[android-developers] Re: Why different icon sizes?
Yes, this is how the system works for drawables. Here a quote from the Android documentation: The system handles most of the work to render your application properly on each screen configuration by scaling layouts to fit the screen size/density and *scaling bitmap drawables for the screen density, as appropriate*. (Source: http://developer.android.com/guide/practices/screens_support.html#support) The only real problems arise when: 1. Your only drawable available has a too low resolution. Upscaling on a high density screen will make it look slightly blurry. That is especially noticeable when your app icon is right next to a hi-res icon. 2. The Android system's scaling introduces unwanted artifacts. By providing your own set of icons you have full control over the appearance. This is especially an issue with 9-patch drawables, since the slice markers may bleed into the image area due to interpolation and the markers themselves may not be readable anymore for slicing up the image. So especially in case of 9-patch drawables you probably want to provide different versions for each supported screen density.

[android-developers] Re: About Application promotion
I guess key in 3) is without informed user action. In your scenario tapping a banner ad is a user action. What appears to me as legal grey area is the informed user bit. How can we possibly know that the user is informed and does in fact know that they are clicking a banner ad for an app, that will open its Google Play store page for installation? That phrase implies that the user is supposed to be knowing what they are doing. What this Google Play policy probably tries to express is that the banner ad must not be deceptive in any way. If you style the ad as a button or any other UI element in your app A, and if it is not obvious that it is actually an ad, then you are violating that policy, because the user is not informed anymore. Their action of tapping the ad does not translate to the intended effect anymore. That means that your app ads must be recognizable as such probably by wording, appearance and also by the position on screen.

[android-developers] Re: SQLite case insensitive matching
There rings a bell with your problem description. It's a while ago, but I remember now that I'm having similar problems with one of my apps and non-ASCII characters. Since you are using the MATCH operator I assume you are also using the FTS3 extension. I just found this piece of information on the documentation page for FTS: *All uppercase characters within the ASCII range (Unicode codepoints less than 128), are transformed to their lowercase equivalents as part of the tokenization process. Thus, full-text queries are case-insensitive when using the simple tokenizer. * (source: http://sqlite.org/fts3.html#tokenizer) That may explain why French accented lower-case letters are not correctly matched against their upper case equivalents, since they are effectively ignored by the default tokenizer. The same page mentions further down that the unicode61 tokenizer implementation solves that problem correctly, however it looks like it is only available for FTS4, which in turn is only available since Android ICS (see http://stackoverflow.com/questions/6339022/sqlite3-fts4-match-and-android). A dirty workaround would be to create an ORed match query for both upper case and lower case versions of accented letters: SELECT * FROM MyTable WHERE content MATCH 'Écuter OR écuter' This however can get out of hand the more accented letters are contained in your search query. But if the data in your database is written according to standard writing rules (all lower case letters except for titles and words at the beginning of a sentence) you could focus just on the first letter of the search term for creating those ORed match queries. On Saturday, April 18, 2015 at 4:03:28 AM UTC-7, Doug Gordon wrote: Similar questions have been asked, but many are old and it's not clear to me exactly what the resolution is. I have a list filter with a local db query that is matching columns against user input (uses MATCH, but that is probably not significant). Both the contents of the columns and the user input can be mixed case, but the match should be case-insensitive. This has been working (for years!) for most situations, but it was recently pointed out to me by a user (in France) that if he inputs a lowercase accented character, e.g. é, it will not match a database entry containing the uppercase equivalent, e.g. É. My understanding is that Android SQLite does not support this automatically as it does for ASCII characters, but is there a solution within Android? I have no control over what is in the database (it comes from an outside source) or what the user inputs.

[android-developers] Re: Android Studio needs create library function! And Android needs a different OS Name!
I had a similar problem with wrapping my head around this libraries issue
when I started using Android Studio and Gradle just a few weeks ago (see
discussion here
https://groups.google.com/forum/?fromgroupshl=en#!topic/android-developers/O1hSIbQK0SU,
also for an overview of the available options). You would usually add 3rd
party libraries as module dependecies to your app project (hit F4 and go to
Dependencies tab, click the green plus icon and select Library
dependency). An online repository is searched for the requested library
(also taking the requested version number into account). As far as I
understand, that library will be downloaded once into your local Maven
cache, which will be used by all your app projects. So in this case there
should be no redundancy.
When it comes to self-developed library modules you can do the same. I get
around this module-inclusion problem by deploying development snapshots of
my own libraries into my local Maven repository and adding them to the
dependencies list of my Android app. No redundancy here. Libraries can be
centrally maintained and developed outside the app project. The same with
3rd party libraries, they also can be added as dependencies from online
repositories. The whole project organization and setup is driven by Gradle
build files. You are free to configure it any way you wish.
I do not quite understand the system property problem and I think there's
also no point in requesting any change. Android updates are super-slow to
roll out and it would take many years until you could rely on that feature.
A library that interfaces with the Android API is also usually compiled
against the Android SDK, so the programmer should be well aware of the
presence of Android. Unless you access the Android API via reflection, but
in this case you can just use reflection to figure out that your code is
running on Android.

It is the lazy man's way out, yes. But if one uses his own libraries across
many projects, it'd be a nightmare. The current method of having different
libraries inside the same project is very bad.
Libraries should be managed from one project to reduce headaches, double
work, not knowing which file is where, etc. In other words, 1 lib project
for all app projects to use will definitely prevent many FUBAR scenarios
that waste everyone's time and makes everyone angry.
Look at how Netbeans does it. That is the way to go.
One more thing I have noticed, is that os.name returns Linux, not
Android. This is not so good. If it returns Android, programmers can
utilise existing libraries for desktop versions of Java and adapt it to
android quickly. Hell, you can even put Linux Android or the other way
around. As long as there is a way to differentiate between desktop and
mobile.
For example:
if(System.getProperty(os.name).equals(Android)){
//android implementation here.
}
else{
//desktop implementation here.
}

Re: [android-developers] Re: What is wow factor about android studio in compare to Eclipse.
Yesterday I tried to set up a web project in IntelliJ IDEA 14 CE and Android Studio. It did not work because all the necessary plugins are reserved for the commercial version of IntelliJ IDEA. Which is fine with me. They are running a business after all. But I guess that may prove your point. It's not really an entirely open IDE and not entirely Open Source, since some features are locked away behind a paywall and the community does not deliver Open Source alternatives, yet. Anyway, after two weeks of daily use of Android Studio I have to agree with what kj said. I prefer IntelliJ over Eclipse because of so many little things. To be on thread topic here: the features that wow me most at the moment are the intelligent code completion http://jetbrains.dzone.com/articles/top-20-code-completions-in-intellij-idea, the resource value previews (strings, constants, drawables) that are embedded directly in the source code, and the whole project configuration through Gradle build files thing. Kind of neat. What drives me nuts at the moment are the bugs. The logcat view is always empty for me and makes the IDE unstable when open. Android Studio also tends to slow down my machine after a few hours of work. And my biggest pet peeve are the default keyboard shortcuts that are not entirely suitable for work on KDE, since some are already defined there. I also do not understand why the default shortcuts are so deliberately non-standard. But other than that I'm happy with Android Studio.

[android-developers] Reusable code organization with Android Studio
I've been pulling out my hair over this in the past two days and searched
the Internet for best practices when it comes to organizing reusable code
in an Android Studio project. Coming from an Eclipse development background
it's not really all that intuitive to understand. This post is a bit
longer, so bear with me.
*TL;DR:* *What's your best practice when it comes to module organization
and version control?*
The way I organized code so far using Eclipse for development and Apache
Ant for building projects allowed me to easily keep the app project
separate from its library projects. They could reside in different
directories that belong to different version control system repositories.
Now with Android Studio and my limited understanding of Gradle and the new
build process I am basically forced to have all so-called library
*modules* arranged as sub-directories of the main app project directory.
In terms of code organization I have the following options:
- *I use only a single massive repository *that is basically an Android
Studio project that hosts all my Android app modules and custom library
modules
- This is not going to happen
- I keep app projects in separate repositories and *I import my
custom library modules*
-
*Importing a module creates a copy of the original *
- This means *redundancy* and *code synchronization issues*. I may
forget to merge back changes I've done to one of the library modules
- Unfortunately this is the official solution provided by the
IntelliJ IDEA documentation
https://www.jetbrains.com/idea/help/sharing-android-source-code-and-resources-using-library-projects.html#d806616e254
- I keep app projects in separate repositories and *check out my
library modules from a separate repository as a Git submodule
http://git-scm.com/book/en/v2/Git-Tools-Submodules*
- I *cannot cherry-pick the needed library modules* from the Git
repository. Git submodule checks out the whole library repository
- It does not play nicely with that one level deep project/module
directory structure for Android Studio projects
- I set up a *Maven repository for my library modules* and add the
needed modules as dependencies to my app project
- Very elegant, but...
- Every single tiny change in my library code requires rebuilding and
deploying the module.
- I also fear that I need to increase the version code / build number
every single time so the local Maven cache gets updated? I have no
experience with this. :-/
*Here is what I am currently doing* and I'm not sure if it's good enough or
can be considered a best practice:
This is my directory structure for app projects:
\ projects
\ my-android-libs (checked out from library modules repository)
\ module-1
\ module-2
\ ...
\ App-1 (checked out from App-1 repository)
\ app
\ ...
\ App-2 (checked out from App-2 repository)
\ app
\ ...
As suggested in this post http://stackoverflow.com/a/17490233/1473663, in
any of those app projects I need to alter the settings.gradle file and add
the desired module dependency like this:
include ':app'
include ':module-1'
project(':module-1').projectDir = new File(settingsDir,
'../my-android-libs/module-1)
Then I also need to add to the app module's build.gradle file a compile
project statement to the dependencies list:
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:21.0.3'
compile project(':module-1')
}
This workaround works so far and right now it's the lesser evil for me.
However, I'm still totally new to Android Studio, Gradle and Maven and I'd
like to hear if you guys know some best practices when it comes to module
organization, project setup and version control. I'm especially interested
if anyone of you goes with the private Maven repository solution and how
that works for you.

[android-developers] Re: How to implement crossfade texture effect in Opengl?
OpenGL ES 2.x and higher are the way to go, so you probably won't get around coding your own shaders. That comes with a lot of advantages and a few problems. Yes there are some compatibility issues but they are universal and also affect desktop GPUs due to subtle inconsistencies in driver implementations. The article you linked to points out the main problems I also encountered. However, those issues do not mean that you should avoid using the OpenGL ES 2.x and higher. Take it as a list of best practices to follow. You should also read through the following blog about OpenGL ES programming for Android: http://www.learnopengles.com/android-lesson-one-getting-started/ The articles there also explain how to bind textures, prepare and upload vertex data and so on. I hope they will answer your other questions. In my experience you won't run into big problems with most basic shader approaches. That cross-fading effect should not cause any issues.

[android-developers] Re: How to implement crossfade texture effect in Opengl?
Never tried that myself but from OpenGL ES 2.x you could assign two
textures to a fragment shader that gradually achieves that blending effect
over time. The simplest blending effect would be linear, which has the
basic formula:
P_mix = P_a * (1 - t) + P_b * t
where...
- P_a would be the RGB color channel values of texture A
- P_b the color channel values of texture B
- t would be a time factor ranging from 0 to 1 and
- P_mix is the blended result.
Now my GLSL skills are a bit rusty at the moment. It may look like the
following (without any lighting calculations):
uniform sampler2D texA;
uniform sampler2D texB;
uniform float t;
varying vec2 texCoord;
void main() {
vec4 pA = texture2D(texA, texCoord);
vec4 pB = texture2D(texB, texCoord);
vec4 pMix = pA * (1.0 - t) + pB * t;
gl_FragColor = pMix;
}
From your host app you'd need to animate the uniform value t over time.

Re: [android-developers] Re: Free App suspended for adding Google Analytics?
You could in fact (try) to get around Google's payment processor if you change your donate button into an in-app purchase of a media file that can also be processed by other apps (images, videos, songs, eBook...), see Google Play Developer Policies https://play.google.com/about/developer-content-policy.html: Developers offering additional content, services or functionality within another category of app downloaded from Google Play must use Google Play's in-app billing service http://developer.android.com/google/play/billing/index.html as the method of payment, *except:* - where payment is primarily for physical goods or services (e.g., buying movie tickets, or buying a publication where the price also includes a hard copy subscription); or - *where payment is for digital content or goods that may be consumed outside of the app itself (e.g., buying songs that can be played on other music players). * The only difficulty would be communicating the message to your users that the purchase is meant to be a donation for your work on the app. If you would phrase it like that you still would be violating the policies.

Re: [android-developers] Re: Physical address is required for paid apps or in-app purchases
I added all information on both tabs, with the same address, since I'm running a business. The legal profile is likely just between you, Google and the authorities which will be contacted by Google to validate your business. The public profile is probably the one you want to be careful with, if you want to hide your home address. In my experience, the legal profile is the more important one. It should be absolutely identical with whatever records you have filed with your bank and tax authorities. In my case Google denied payment a few months ago because they found a tiny typo in my business address and they said they could not match it against the records of the IRS. It was something like a missing letter, so they are going to be very pedantic there.

[android-developers] Re: To implement Donation functionality using paypal natively
The current Google Play Developer Program Policies https://play.google.com/about/developer-content-policy.html state the following about payment processing and monetization: *Paid and Free Apps* - *App purchases:* Developers charging for apps and downloads from Google Play must do so by using Google Play's payment system. - *In-app purchases:* - - Developers offering virtual goods or currencies within a game downloaded from Google Play must use Google Play's in-app billing service http://developer.android.com/google/play/billing/index.html as the method of payment. - Developers offering additional content, services or functionality within another category of app downloaded from Google Play must use Google Play's in-app billing service http://developer.android.com/google/play/billing/index.html as the method of payment, except: - where payment is primarily for physical goods or services (e.g., buying movie tickets, or buying a publication where the price also includes a hard copy subscription); or - where payment is for digital content or goods that may be consumed outside of the app itself (e.g., buying songs that can be played on other music players). - Developers must not mislead users about the apps they are selling nor about any in-app services, goods, content or functionality they are selling. If your product description on Google Play refers to in-app features to which a specific or additional charge applies, your description must clearly notify users that payment is required to access those features. These conditions do not explicitly mention donations, but the way I read it is that using a 3rd party payment processor such as PayPal is only forbidden when the payment is meant for the app itself or extended features and goods that can only be used / consumed with the app. According to those conditions it's probably also not allowed to ask for PayPal donations for your programming work, since that could be seen as a late payment for the app. I would say that donations for a good cause unrelated to yourself and your app, are acceptable. To be sure you could either try and get in touch with the Google Play developer support team https://support.google.com/googleplay/android-developer/ or consult a lawyer.

[android-developers] Re: Image captured from my app is rotated by default
This is expected behavior, and Doug's assumption is right. JPEG images may contain EXIF http://en.wikipedia.org/wiki/Exchangeable_image_file_formatdata blocks that also specify the orientation of the image. On your server you need to read the orientation data and use it to rotate the image into the opposite direction. If your server code is written in PHP you can use the Imagick library and the following functions for determining the orientation and rotating the image respectively:Imagick::getImageOrientation()http://www.php.net/manual/en/imagick.getimageorientation.php, Imagick::rotateImage()http://www.php.net/manual/en/imagick.rotateimage.php . If the server software is written in Java you could use a library such as Metadata-Extractor http://code.google.com/p/metadata-extractor/ for reading the orientation and any image processing library of your choice for rotating the image.

[android-developers] Re: ANR from internal function
I guess the solution is trying to debug the heck out of it, that's also what the OP was basically asking for. The causes in her/his case will most likely be too different to be useful for you, since I think it's related to multithreading deadlocks due to bad locking / synchronization. I had similar problems in my last game, because I screwed up at some places. Proper thread synchronization can be subtly difficult to implement. What you could do is running your app using a debugger. As soon as the app gets unresponsive, look into the list of currently active threads that belong to your app process (in Eclipse that would be in the debug view in the debug perspective). As far as I recall, locked up threads are marked as waiting. You should be able to see the currently executing method names and complete call stacks per thread. Their locations in code may give you hints what's causing the problem. You also may have to pause your app in order to avoid that crash happening.

[android-developers] Re: Activty on orientation
By default the activity gets recreated on certain events such as orientation change. This is, as far as I know, the preferred behavior. You can handle these so-called runtime changes (such as orientation change, but there are more events that trigger activity re-creation such as changed system language) yourself by specifying the android:configChanges attribute of your activity in the manifest XML file. Handling orientation changes yourself will basically tell Android not to re-create the activity in case of an orientation change, and therefore your view hierarchy will be retained. See herehttp://developer.android.com/guide/topics/resources/runtime-changes.htmlfor more information.

[android-developers] Re: LVL: possible to check license for a different app?
Educated guess: the UID may be the app's user id (UID). As far as I know, Android creates a unique user for each installed app for enforcing app-specific file system permissions. The licensing service probably checks that the requesting app process' user id matches the user id for the requested package. So it looks more like a security check and I'd assume that you cannot work around that, unless you'd run your request as that other user. And that's probably only possible on a rooted device.

Why would I want to do this? I'm developing an app which I'm considering publishing using a free + pro license model. The main app would be a free, ad supported app. To turn off ads the user would purchase a pro license key from the market (published as a paid app containing no functionality). The user would continune to use the app that was downloaded for free, which checks if the paid app is installed, and if so it disables ads. I prefer this model to a fully featured paid app model, as it eliminates the need to migrate data from the free version to the paid when the user upgrades. Under this model I would like the free app to check if the paid app is installed, and if so the free app would then use LVL to check if the user has purchased the paid app via the market. Will it be possible for the free app to pass the package name of the paid app to LVL, and to get back a result confirming whether the paid app has been purchased or not? Looking at the LVL source code I suspect I can do this by modifying the constructor of LicenseChecker to set mPAckageName to a supplied argument rather than setting it to mContext.getPackageName().

It could be just about any app that uses some ad(ware) SDK. As far as I know doing that kind of thing also requires a specific permission ( com.android.launcher.permission.INSTALL_SHORTCUT).

[android-developers] Re: licensing - ServerManagedPolicy not caching
Actually Google isn't doing their developers any favor with the LVL. The documentation reads like it is meant to serve as a drop-in solution that adds reliable DRM to your paid app. Just configure it a little bit with some policy and your app is safe. On the other hand there is that lengthy Google I/O talkhttp://www.google.com/events/io/2011/sessions/evading-pirates-and-stopping-vampires-using-license-verification-library-in-app-billing-and-app-engine.htmland some official blog postshttp://android-developers.blogspot.com/2010/09/securing-android-lvl-applications.htmlthat discourage from using the LVL as is, since all its components are known and a cracker can easily find them in your decompiled Java code and just remove them. The LVL is more of a proof of concept that should give you ideas how to interface the Play licensing service. That means changing and rewriting the whole LVL up to a point where the original is not recognizable anymore and at that point you understand every single bit of it yourself and don't run into that policy problem anymore, because you'd implement that policy yourself. I voiced my opinion about the LVL and DRM here in the past and I used to be in favor of all these efforts. But trying to do it as properly as possible is a lot of additional overhead (it took me almost a week the first time), and when not done properly it either does not protect your app at all and / or pisses off legitimate customers. So I decided to get rid of any kind of DRM in my products altogether. It makes me sleep better because I know that it won't accidentally accuse one of my paying customers of theft just because I may have done some silly mistake. And in the end, if your app is interesting enough someone will crack it anyway. I guess it's more important to focus on those people who are willing to pay for your work and services. And maybe it really does help to see those cracked copies as some kind of free advertisement for your name and brand. If you still want to implement DRM for your app, then watch that video I linked above. It's probably as in-depth as it can get when it comes to the LVL.

I have licensing added to my paid game, but I've found it goes online to check for a license every single time the app is run, instead of only occasionally doing it, as it's supposed to do with the 'servermanagedpolicy' as opposed to the 'strict policy'. there are no ads in my paid game and I don't want the user to always have to be online and wait for verification for every play. now I actually set a flag in the 'preferences' file the first time the license check succeeds, so it doesn't check for licensing at all after the first check, although I imagine this could be easy to hack for piraters. should the servermanagedpolicy' be cacheing something in the phone so it doesn't have to check every play? here is the policy in the docs: A flexible Policy that uses settings provided by the licensing server to manage response caching and access to the application while the device is offline (such as when the user is on an airplane).

[android-developers] Re: CSS Height % Not working in Android App Screen
I'm not sure if this is the cause but I noticed that your sample HTML page
is missing a view port meta tag, which is commonly used in mobile web
pages. The rendering logic is a bit different in mobile browsers due to the
smaller screen size of mobile devices. Here is an explanation of mobile web
browser view ports: http://www.quirksmode.org/mobile/viewports2.html
You have to add a meta tag to your HTML page header that tells the mobile
browser something along the lines that the view port has to match the
actual device screen width. Here is a Mozilla documentation page that
explains it very well:

[android-developers] Re: Android how we can free the RAM memory of the device.
I could imagine that forcing the OS into a low memory situation might trigger what you want. By temporarily allocating large blocks of memory from native code (using the NDK) the OS may try to stop background apps and services which in turn will free their claimed resources and RAM. Don't forget to free your allocated memory.

AndroidQuery works with an ExecutorService and that my callback objects
also are getting garbage collected when the Runnable has to wait for its

aq.progress(new ProgressCallback() {

@Override
public void setMax(int max, int progress) {

Is there a way to pass such a callback object without loosing the
reference when it is referenced inside an WeakReference object?

Try to debug by retrieving the GL error code: Log.d(GL Error, gl.getErrorCode()); When the value is non-0 then there is an error. You need to identify the GL function call causing that error state. You could for example add a logging output line after each GL function call like this: gl.glEnable(GL10.GL_FOG); Log.d(Enable fog, gl.getErrorCode()); gl.glFogx(GL10.GL_FOG_MODE, GL10.GL_EXP); Log.d(Set fog mode, gl.getErrorCode()); gl.glFogfv(GL10.GL_FOG_COLOR, fogColorsBuffer); Log.d(Set fog color, gl.getErrorCode()); If you get a non-0 number you need to look up the meaning of that error code.

Re: [android-developers] Re: .db files being renamed to .back
The SQLite documentation http://www.sqlite.org/limits.htmlsays that the maximum database file size is 2,147,483,646 pages A single page can range from 512 to 65,536 bytes. So the minimum page size configuration would yield a maximum database file size of 1 TB. So something else is going wrong here. Out of curiosity I checked the vanilla SQLite C source code for occurrences of .back and could not find anything. Just a vague guess: it looks to me like some odd kind of data corruption recovery handling. In older versions of Android the strategy was just deleting the corrupted database file and starting from scratch. It could be a vendor-specific customization or maybe a different firmware like CyanogenMod. But I think it's more likely that your customers who report that problem are to blame. Probably by misusing some file manager or backup software as gjs already mentioned :-/ Could they recover their data by renaming these .back files to .db?

[android-developers] Re: why does SharedPreferences framework allow you to insert a preference with a null key - given it can't reload the preferences afterwards?
I quickly peeked into the source code and well, this is the way how it is
programmed. When an exception occurs while the preferences data file gets
read, SharedPreferences sets internally an empty map so you start from
scratch. I even dug a bit deeper. The XML serializer just ignores NULL keys
and creates XML output that cannot be properly read anymore through the map
deserialization method which seems to expect an existing key value.
As for why it has been programmed like that... I think the reasoning may be
that preferences are not deemed to be of so much importance that it should
make the app crash in case of failure. This error state is silently
discarded and you start over with the defaults. I think that's a reasonable
approach since any app should be able to start over with empty preferences.
In this particular case you may have discovered a tiny bug you may want to
report. But to be honest, using null keys is a pretty unusual thing to do.

[android-developers] Re: Signed APK corrupt on deploy. FC with Class Not Found exceptions
If it just happens with the release version this may be a ProGuard misconfiguration issue. Class not found and Method not found exceptions are symptomatic for that. Check the exact exception message for the class name that couldn't be found. Make sure that your release build really contains that class (it may be part of a linked library or JAR file, make sure that it really gets included with your APK, there are various ways and tools for doing so like dex2jar). If it is in fact an obfuscation problem you need to add ProGuard rules for protecting this class (and probably others, too) from being obfuscated.

[android-developers] Re: NDK: faster alternative to JNI based custom rendering
As you already pointed out, floats can be a bottleneck. In many cases it is possible to rewrite graphics algorithms in a way to make exclusive use of integers. You need to get rid of the fractional part and that can be done by scaling up all values depending on your needs for the precision. When all calculations are done you need to scale the numbers down again. Multiplications and especially divisions can be expensive, too of course. When your scale factor is a power of 2 you can use bit-shifting instead of multiplication and division which is computationally as cheap as it can get. I wrote a small image processing and drawing library a while ago and wrote all algorithms to make use of integers. In case of convolution matrices it was possible to speed up the calculations up to 3 times compared to their floating point counterparts. Another speed optimization trick is precomputing a table of reoccurring or known terms and values. This can be done with gradients for example. What I didn't dabble with yet is ARM's NEON extension. I read all over the place that (if used correctly) it can give you another significant speed boost. GCC provides some intrinsicshttp://gcc.gnu.org/onlinedocs/gcc/ARM-NEON-Intrinsics.htmlfor the extension. And as far as I know you can also tell GCC to automatically optimize for NEON. Since not all ARM CPUs are equipped with that extension this may be dangerous, though, unless you create a version for NEON and a standard version and determine on runtime which one to load and use. Android's RenderScripthttp://developer.android.com/guide/topics/renderscript/compute.htmlmight be a pretty fast solution, too, but I'm not sure if you'll be able to easily convert your drawing algorithms to make it work with it. It's basically pretty good at crunching numbers and quickly running convolution matrices for image processing by using the GPU and theoretically all available CPU cores.

[android-developers] Re: getRotationMatrixFromVector() broken on Note 3
As a temporary fix you could just copy-paste the original source code from
the Android SDK as a drop-in replacement:
public static void getRotationMatrixFromVector(float[] R, float[]
rotationVector) {
float q0;
float q1 = rotationVector[0];
float q2 = rotationVector[1];
float q3 = rotationVector[2];
if (rotationVector.length == 4) {
q0 = rotationVector[3];
} else {
q0 = 1 - q1*q1 - q2*q2 - q3*q3;
q0 = (q0 0) ? (float)Math.sqrt(q0) : 0;
}
float sq_q1 = 2 * q1 * q1;
float sq_q2 = 2 * q2 * q2;
float sq_q3 = 2 * q3 * q3;
float q1_q2 = 2 * q1 * q2;
float q3_q0 = 2 * q3 * q0;
float q1_q3 = 2 * q1 * q3;
float q2_q0 = 2 * q2 * q0;
float q2_q3 = 2 * q2 * q3;
float q1_q0 = 2 * q1 * q0;
if(R.length == 9) {
R[0] = 1 - sq_q2 - sq_q3;
R[1] = q1_q2 - q3_q0;
R[2] = q1_q3 + q2_q0;
R[3] = q1_q2 + q3_q0;
R[4] = 1 - sq_q1 - sq_q3;
R[5] = q2_q3 - q1_q0;
R[6] = q1_q3 - q2_q0;
R[7] = q2_q3 + q1_q0;
R[8] = 1 - sq_q1 - sq_q2;
} else if (R.length == 16) {
R[0] = 1 - sq_q2 - sq_q3;
R[1] = q1_q2 - q3_q0;
R[2] = q1_q3 + q2_q0;
R[3] = 0.0f;
R[4] = q1_q2 + q3_q0;
R[5] = 1 - sq_q1 - sq_q3;
R[6] = q2_q3 - q1_q0;
R[7] = 0.0f;
R[8] = q1_q3 - q2_q0;

}
}
Interestingly enough the original code does not explicitly throw the
exception you mentioned. So it must be some weird Samsung hack. You could
try registering with Samsung as a developer and use their support ticket
system in order to tell them about this problem. However, I already
complained once about one of their SDKs and never heard back from them.
On Wednesday, October 2, 2013 8:41:01 AM UTC-5, String wrote:
I've been getting error reports from users of the Note 3 that boil down to
the following:
*java.lang.IllegalArgumentException: R array length must be 3 or 4*
*at
android.hardware.SensorManager.getRotationMatrixFromVector(SensorManager.java:1336)
*
This function, *getRotationMatrixFromVector()*, is documented as a
Helper function to convert a rotation vector to a rotation matrix. Given a
rotation vector (presumably from a ROTATION_VECTOR sensor). My typical
call to this function looks like this:
*SensorManager.getRotationMatrixFromVector(R, rotationVector);*
Where the *rotationVector *comes from the hardware accelerometer and
gyroscope, and (despite the error message about *R*) it's with this
parameter where the problem lies. It's directly passed from
*android.hardware.SensorEventListener.onSensorChanged(SensorEvent
event)* for a *Sensor.TYPE_ROTATION_VECTOR* event. The *event *parameter
there has a *values *property that is passed as the *rotationVector *in
the previous call. And according to the docs at
http://developer.android.com/reference/android/hardware/SensorEvent.html#values,
this array can legitimately have up to 5 elements - moreover, in Android
4.3, it *should *have all 5. However, passing an array of length 5 causes
the Note 3 to crash on the aforementioned *IllegalArgumentException*; it
seems to expect 4 elements at most.
So, here's the summary: Android 4.3 passes an array with 5 elements to
this hardware event, and the Note 3 throws an exception when passed that
same array to the system-defined helper function for that event. This
behavior does not happen on the other 4.3 devices I have at hand (Galaxy
Nexus and Nexus 7); it appears to be a basic flaw in the Samsung
implementation of 4.3.
And I know, this all looks like minutiae of a hyper-specific issue - but
believe me, it's likely to be encountered by any app using the device's
motion sensors. A Google search for *getRotationMatrixFromVector *returns
51,400 results.
Any comment from Samsung on this would be most welcome, if unlikely.

[android-developers] Re: Should SQLiteDatabases be limited to 2Gig?
I just did some digging around and your error code translates into the following define constant: *SQLITE_IOERR_FSTAT*http://sqlite.org/c3ref/c_abort_rollback.html So basically it's an fstat error which according to this threadhttp://sqlite.1065341.n5.nabble.com/reasons-for-SQLITE-IOERR-FSTAT-td66646.htmlcan happen when you try to access the database after it (or one of the journal files) have been deleted. Othershttp://t3391.codeinpro.us/q/51502007e8432c04261a3ca8also mention that this error has to do with changing data while another thread is trying to read it simultaneously. I guess the write-ahead journaling of SQLite does not mix well with thread concurrency. In my experience you should try to synchronize all concurrent read and write access to your SQLite database yourself and not rely on the built-in locking facilities (they never worked for me correctly).

[android-developers] Re: AudioTrack
From the documentation of
AudioTrackhttp://developer.android.com/reference/android/media/AudioTrack.html
:
It allows streaming *PCM audio buffers* to the audio hardware for playback.
PCM is basically uncompressed audio data. MP3 is compressed audio that's
why you hear noise. You have two options for solving that problem:
1. Decode your MP3 stream on the fly and feed it to your AudioTrack
2. Use
MediaPlayerhttp://developer.android.com/reference/android/media/MediaPlayer.htmlinstead
of AudioTrack

[android-developers] Re: Detect a gesture startet from the outside of a view
You could still try the approach I described by getting rawX and rawY from
the motion event and match it with the global rect position of the target
view. Motion event coordinates are usually in a local coordinate system. I
guess the local coordinate system is the one of the ImageView you start

Hi :)
Thanks for your post
I'm trying to implement specific gesture between images...no drag drop
The images are inside *GestureOverlayView (because of prediction =
gestureLibrary.recognize()...I don't know how to recognize a gestures which
have curls or shapes)*, and I thought the parent intercepts touch event
automatically (by automatically I mean set the OnTouch listener to the
parent).
Don't you think inheritance is wrongly used in this case??
Anyway..I used *gestureOverlayView.setOnTouchListener* to intercept
touch events on children, and *
gestureOverlayView.addOnGesturePerformedListener* to check whether the
gesture was recognized, and user's finger passed through both images.
The problem now is that in *gestureOverlayView.setOnTouchListener,*instead
of ACTION_UP, I get ACTION_CANCEL :S
I don't know if it should be like that

So let's say you create a derivative class L of your layout that

You could override

L and check for the following motion event states:
*1. Gesture started (ACTION_DOWN)*
Iterate your list of ImageView children of L and see if the touch event
point is in one of them. If yes, your gesture starts.
The View class has the method getGlobalVisibleRect(Rect,
Point)http://developer.android.com/reference/android/view/View.html#getGlobalVisibleRect(android.graphics.Rect,%20android.graphics.Point)which
can be used for checking if your touch event coordinate hits one of
your image views. It would roughly look like the following (not tested
since I'm not sure if these methods return locations in screen or window
coordinate system, you may need to debug it):
*Rect* r = new *Rect*();* *// should be class member you can reuse
float x = motionEvent.getRawX();
float y = motionEvent.getRawY();
*for*(*ImageView* iv : imageViews) {
iv.getGlobalVisibleRect(r);
*if*(r.contains(x, y)) {
// Touch event is inside image view
}
}
*2. Gesture ongoing (ACTION_MOVE)*
If you visualize your gesture by drawing some trail or moving around the
first touched image view then this is the right point to do so. Here you
can update your view(s).
*3. Gesture finished (ACTION_UP)*
Here you need to iterate your ImageView children again in order to see
if the finger has been lifted over another image view. In that case your
gesture was successful.
*4. Gesture canceled (ACTION_CANCEL)*
Whatever your gesture is doing should be canceled here.

[android-developers] Re: SurfaceHolder.setFormat() only working when called from the *wrong* thread?
I'm not sure if I understand you correctly when exactly you set the format. It sounds too me as if you're setting it too late, after the OpenGL ES context has been created. What I do is setting the format in the Activity's onCreate method on the UI thread before the OpenGL context is initialized and before a renderer has been set. Maybe your setFormat call is postponed in a way so you lose the OpenGL context and it forces a re-creation? I guess it just works for you on different devices because your call to setFormat does not actually change the format, so nothing happens. Your older 2.2 Android device may have a different default format for the surface view (such as RGB565) compared to newer devices. On Friday, August 23, 2013 1:11:57 PM UTC-5, latimerius wrote: In a testing program I'm playing with currently, I want to use setFormat() to adapt the pixel format of my surface to the chosen EGL config before I pass the surface holder to eglCreateWindowSurface(). Now, I call EGL from my render thread and I know SurfaceHolder.setFormat() is documented to have to be called from the same thread running the SurfaceView's window, which I take to be the main thread. To comply, I wrap my setFormat() call in a Runnable which I pass to runOnUiThread() and wait() until it's actually executed. This works perfectly on some devices, however it gives me intermittent failures on Optimus One (with Android 2.2) - on program start-up, three times out of four the screen is just black. Even if start-up goes right, the first configuration change makes the screen go black. The program still runs and no GL or EGL calls signal any errors. Here's the weirdest part - if I omit the runOnUiThread() stuff and simply call setFormat() from my render thread, it fixes the problem and the program runs 100% solid on Optimus no matter much beating I give it - randomly pressing Home and Back while rotating the device wildly, putting it to sleep and waking it back up, the renderer always handles the native window changes correctly and renders just fine.

[android-developers] Re: Designing Help into Your App
Personally I always go for option 2, a full screen webview in an extra activity for displaying help for the current page. I store localized HTML files in the assets directory. It's just a matter of adding some language code to the file names and loading the correct page for the current locale while falling back to English. It works so far for me. I also agree with what TreKing: it's not a top priority for most developers. But in my humble opinion they probably shouldn't write the end user documentation of their own apps in the first place. First of all because of some kind of blindness when it comes to possible real help questions. They know their babies inside out. Second of all documentation written by programmers tends to sound way too technical. I guess it's better to let somebody who isn't that technical but good at writing do that job. And that person should try to figure out the app with a fresh pair of eyes. Ultimately I don't think that users really care that much about detailed context-sensitive help texts because of *tl;dr. *Most users require the app to be self-explaining. At best there should be some easy to understand tutorial overlays that explain UI elements with arrows and short texts. In an early version of my latest game I tried to force the player through a 4 minutes tutorial that explains with an animated character every aspect of the game. I was thinking that ought to be alright and digestible for a one-time experience. But my beta testers felt bored and complained about that. So I went with that overlay mini-tutorial approach. No more complaints.

[android-developers] Re: drawBitmap Flip, Scale and Translate
Keep in mind that the origin of a bitmap draw operation is the upper left corner of the bitmap. So is the origin of canvas (unless you change it with a transformation matrix). When you tell canvas to render everything flipped horizontally and draw the bitmap on the canvas at (0;0) the bitmap will be rendered outside the canvas to the left. Just imagine that all pixel coordinates of canvas are multiplied by your scale values. Your x-axis scale value gives every pixel's x-coordinate a negative sign. So every pixel on the visible side of the canvas is flipped alongside the left edge of the canvas and become invisible. You need to translate the bitmap horizontally to compensate for that. You can set an additional postTranslate on the transformation matrix. Or you could set the x-coordinate of the bitmap draw operation accordingly. Matrix flipmatrix = new Matrix(); flipmatrix.setScale(-1, 1); flipmatrix.postTranslate(-canvas.getWidth(), 0); I haven't tried that myself and I'm sometimes also a bad with affine matrix calculations. I'm not sure about the negative sign of canvas.getWidth() so you probably need to play around a bit with that. You also probably should try a plain bitmap draw operation without source and target rect but just coordinates in order to see if that works for you.

I'm not sure if that really works properly with animations, since I'm not sure how and if they trigger re-layouts. But in theory you could try android:gravity=bottom in your RelativeLayout or use android:alignParentBottom=true in your bar child views. If this doesn't work, you may have to bite the bullet and create a custom view that just renders your bars the way you need it. But maybe someone else has a better idea.

[android-developers] OpenGL ES 1.1 with alpha channel
I have a problem with setting up OpenGL ES 1.1 with alpha channel support. First of all: I need an alpha channel within OpenGL ES for performing alpha masking and blending effects. My game uses a texture with alpha channel for masking another texture. This only happens to work when I initialize OpenGL ES with the following configuration: glView.setEGLConfigChooser(8, 8, 8, 8, 0, 8); I could use the stencil buffer instead and parts of my game do that, too. However, my Nexus 7 tablet crashes pretty hard with a colorfully distorted screen when I use the stencil buffer in conjunction with alpha testing (which is necessary for discarding transparent pixels in the masking texture): gl.glEnable(GL10.GL_ALPHA_TEST); gl.glAlphaFunc(GL10.GL_GREATER, 0.05f); Romain Guy says herehttps://groups.google.com/d/msg/android-developers/enRw0sImmN0/uXPWFJ7fQzcJthat the alpha channel set in setEGLConfigChooser does not need to be used unless the window is translucent. However, when I compile my game with: glView.setEGLConfigChooser(8, 8, 8, 0, 0, 8); // alpha = 0 My texture masking effect does not work anymore. Instead I can only see the unmasked texture hovering as a square on the screen. All other textures with alpha channel are rendered correctly but only when I don't try to alpha-mask them. I could leave the configuration with 8 bits alpha channel. However, then I get on some older devices crashes with an EGL_BAD_MATCH error because their surface view apparently only supports RGB565 or maybe even something worse than that. I tried fixing the problem as follows: glView.setEGLConfigChooser(5, 6, 5, 8, 0, 8); But that does not work either (config chooser cannot find a matching configuration). What can I do in this situation? How can I keep my alpha channel within OpenGL ES (I don't need it for the surface nor the window) and make older devices happy without crashing right on initialization? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Need to show a dialog on top of all other Apps for a custom hardware.
I played around with the Google Play Games Services SDK a bit and it looks like they also have such a kind of dialog that is able to be on top of everything else (and even survives activity transitions). It's the welcome log in message that pops up on top of the screen. I'm not sure where the code for this popup resides. You may want to take a look at the SDK code, though I believe you may not be able find it there since it could be part of a system component (Play Services system app).

Re: [android-developers] [Market] Commenting unpublished application
In response to my own question and for the public record: Everybody who downloads a published (free) app still has access to the unpublished market page by opening the direct market page URL. You can still download it from scratch when the app is not there on your device and you can also update it. It's pretty convenient, because I can still roll out updates for an unpublished app. People are apparently not notified through the Google Play app about it, but my app has its own update notification feature, so that's no big deal.

Re: [android-developers] [Market] Commenting unpublished application
I wonder if this is still true, since Google Play changes the rules every now and again. Unfortunately I cannot find any official statement on that matter. My problem right now is that I participated in an AppGratis campaign and I had to unpublish my app. However, people are still reporting bugs and I need to roll out updates somehow without re-publishing that AppGratis app on Google Play. Most users are not tech-savvy enough for side-loading APKs. So are the following assumptions correct: 1. User downloads published app from Google Play 2. App is unpublished from Google Play 3. App gets updated while still being unpublished A) User gets update through Google Play B) User only gets updates as long as the originally downloaded app is installed on the phone C) User does not get updates / cannot install app when she decides to uninstall or switches the Android device On Wednesday, May 2, 2012 10:18:16 AM UTC-5, MagouyaWare wrote: It is my understanding that once a user has downloaded your app they will ALWAYS have access to it in Google Play...

[android-developers] Re: Web search.
Make yourself familiar with regular expressions and try to evaluate the input string for matching known URL address patterns. The problem here is, that your pattern matching must not be strict. So you also need to allow input like www.domain.com domain.com without http(s) protocol prefix which will be the most likely user input. Unfortunately that is a malformed URL and you need to auto-complete it so it gets valid: www.domain.com -- http://www.domain.com/ Everything that does *not *match your URL pattern should be treated as search query. You could pass on that query to Google or whatever search engine of your choice.

[android-developers] Re: Fragments navigation and backstack issue
Hi!
I remember the pain with fragments and the back stack while working on an
app last year. My solution was the following. In the activity's onCreate
method I would do the following:
FragmentManager fm = getSupportFragmentManager();
fm.addOnBackStackChangedListener(new OnBackStackChangedListener() {
@Override
public void onBackStackChanged() {
FragmentManager fm = getSupportFragmentManager();
if(fm.getBackStackEntryCount() == 0) {
finish();
}
}
});
It basically listens to fragment back stack changes and forces the Activity
to finish when the stack is empty

The fragments are shown in FrameLayout content. The navigation bar is

Most of it works as it should, but I have the problem that with a complex
workflow like this:
Start(home) - A - B - A - Back - B - Back
I expect that it will show home, but instead it shows A. I think it's
because the first transaction (home - A) it's in the backstack and it shows
A. But I don't understand why then it works correctly in the simple cases?
The code:
public class MainActivity extends FragmentActivity {
boolean isInHome; //a flag to control when we add fragment to the backstack
or not
@Overrideprotected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

Button a = (Button) findViewById(R.id.a);
Button b = (Button) findViewById(R.id.b);

@Override
public void onClick(View v) {
//clear complete backstack (in this case, just pop home
transaction)
getSupportFragmentManager().popBackStackImmediate(null,

//show home fragment
FragmentTransaction transaction =
getSupportFragmentManager().beginTransaction();
Fragment fragmentHome = new FragmentHome();
transaction.replace(R.id.content, fragmentHome);
transaction.commit();
isInHome = true;
}
});
a.setOnClickListener(new View.OnClickListener() {

that press back on this fragment shows home again
transaction.addToBackStack(home);
}
transaction.commit();
isInHome = false;
}
});

Hi James, as far as I know it's not (reliably) possible to have more than one SurfaceViewhttps://groups.google.com/forum/#!msg/android-developers/fQihJKLki7M/nz4QWV8eyxQJ(or GLSurfaceView) in one Activity at the same time. Since it sounds like you just want to draw graphs, it would be probably better to resort to a custom view component and drawing on a Canvas. If you fancy OpenGL ES rendering capabilities then you should just have a single GLSurfaceView and implement swiping / paging yourself by capturing touch events and drawing the OpenGL ES scene accordingly.

Oh my... when I think about that, I have a pretty old first generation Samsung Galaxy S (I9000). Its internal storage memory seems to be dying and quite a few apps behave erratically, including crashes and data loss. Sometimes it's stuck in an infinite reboot loop. So I'm pretty sure it won't last for too long. I guess these are also probably things to watch out for when talking to customers (how old is their phone, do they store data on an external SD card, because these things can also break and silently corrupt your data.

[android-developers] Yet another EGL_BAD_MATCH problem. How to do it the right way? For all devices?
I have another rather rare problem with OpenGL ES which has to do with the dreaded EGL_BAD_MATCH problem. I do know that there is a correlation between the following factors that yield that problem and make the game crash: 1. The Android device is most of the time rather old with a dated Android version (API level 8 to 10) 2. I explicitly set the surface view holder's pixel format to RGB_888 3. I request the following configuration: setEGLConfigChooser(8, 8, 8, 8, 16, 8); (I have to admit that I probably don't need a 16 bits depth buffer, but I do need the 8 bits stencil buffer) What I have read so far about this problem is the following silver bullet solution: just create your own config chooser. I get that point. But even then developers say on some forums that it crashes on some devices, so apparently it's pretty difficult to find a good matching configuration that doesn't make OpenGL ES crash. How to approach that problem reliably without having all these gazillion Android devices at your hands? Is there a good recipe for that, like a solid generic implementation of a chooser?

[android-developers] Re: GLSurfaceView lag/delay on Galaxy S3.
Hi Edvinas, I need to ask again, because I think that may be the cause of the delay: how do you communicate the touch events to your rendering thread? Because Android can bombard your UI thread with lots of touch events in no time. But your rendering thread needs to peek before updating the game state in regular intervals into the current state of touch input. It's your game loop / rendering thread that needs to dictate the rhythm in order to synchronize the whole experience. What I do in my game is the following: 1. Touch input event handler receives all motion events on UI thread --- converts motion event data into a custom data structure and puts it into one queue that belongs to UI thread 2. Simultaneously the game loop / render thread updates the game state and checks for input first: --- It requests the data from touch handler in a thread safe manner (synchronized) --- Touch handler internally swaps motion data queue A with a secondary motion data queue B --- Touch handler returns queue A to game loop --- Game loop / render thread processes queue data and recycles all motion data structures (so they can be re-used in order to avoid garbage collection activity) And that repeats like this and these two queues get always swapped. That way you let your game loop determine the pace. On Thursday, August 1, 2013 4:30:57 AM UTC-5, Edvinas Kilbauskas wrote: OK, I did that. And yes. It doesn't have the delay anymore!

Other ContentResolver methods behave exactly the same. Also the query methods. It can - without a warning - just return null, even though it works in your tests a million times. You therefore need to check the result for null and come up with a strategy for coping with that problem, like scheduling a re-query or checking if your activity is about to be finished.

[android-developers] Bizarre OpenGL ES rendering artifact on Nexus 7 with Android 4.3
I got a big problem with a game of mine and the latest version of Android. Semi-transparent pixels rendered on the OpenGL ES surface let the underlying activity shine through as following screen shot shows. This problem only appears in a new AppGratis promoted version of the game I just released this morning and here is the really bizarre thing: ONLY the APK downloaded from Google Play has this problem. When I install the same APK that is locally stored on my computer via adb I do not have this problem. I re-installed the Google Play version multiple times and the rendering artifact is always reproducible. It looks like Google Play alters the APK or maybe it is incorrectly installed on the device. However, I do not even know what may trigger that shine through effect. Any help (especially from Google) appreciated. https://lh5.googleusercontent.com/-dHoFBBlJjUo/UfkqiTWOIAI/ADc/PZDIZTdKawQ/s1600/device-2013-07-31-100411.png -- -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Dealing with 1000's of different devices, each one with its own bugs
I think a central website for collecting known issues and workarounds would be a great idea.

We can bring Google's attetntion at this problem but we should be focused on it! If you don't create any workarounds for the buggy devices and just ban them from your app, imagine what could happen for those devices..They would only be able to download 4-5 apps (just saying...)... That would be absolutely perfect. What do you think an user able to download 4-5 apps of that device? -- This device sucks What will the reviews say about it? -- don't buy it What will the vendor producing that device do with next devices? -- be more complain to the standards. But hey, that's was just a suggestion on what one can do knowing the devices causing more issues. The main proposal was to put up a bug database for this kind of issues. -- -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Bizarre OpenGL ES rendering artifact on Nexus 7 with Android 4.3
Tiny update: The SHA1 digest as displayed on the Google Play developer console is identical with the one from my uploaded APK on my computer. So I just guess that the Google Play app installs things differently or it is a really bizarre device quirk. And I do hope it's a rare one because I really dread coping with lots of support requests and bad ratings for a problem I probably cannot solve on my end. -- -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Do SQLiteDatabase references go stale?
How are you handling transactions in your queries? In later versions of
Android SQLite writes by default temporary journaling data files that are
not immediately merged with the actual database file (see here:
http://www.sqlite.org/tempfiles.html). This might be an explanation for the
reported behavior, see the following quote from the SQLite documentation:
However, if the last connection does not shutdown cleanly, the WAL file
will remain in the filesystem and will be automatically cleaned up the next
time the database is opened.
Other than that, are you sure the path argument is always the same?
On Monday, July 29, 2013 7:00:11 PM UTC-5, Nathan wrote:
Based on previous discussions of best practices here, I employ a factory
method for opening SQLite Databases.
/**
* Factory method ensures only one instance of database in memory.
* @param path on external storage
* @return
*/
static public SQLiteDatabase getInstance(String path)
{
try
{
if(alreadyOpened.containsKey(path))
{
return alreadyOpened.get(path);
}
SQLiteDatabase tdb= SQLiteDatabase.openDatabase(path, null,
SQLiteDatabase.OPEN_READWRITE |SQLiteDatabase.CREATE_IF_NECESSARY);
alreadyOpened.put(path, tdb);
return tdb;
}
catch(Exception ex)
{
Log.e(TileDatabase, openExisting, ex);
return null;
}
}
This ensures that an SQLiteDatabase is opened once and closed never, which
Diane and others here said is a reasonable pattern.
Nonetheless, I get some reports from some users that their data
dissappears and reappears. In the morning it works, in the afternoon it is
not available, and the next day it is back again.
Ie, there is a query for blobs in this database and is either coming back
with zero results or throwing a SQLiteException that I am handling and
returning not available. If I manage to get logs from the users, I might
know what exception it is.
So in general, my question is this. Is there a reason that SQLiteDatabase
object may become inneffective, due to some changes in the system or
something I am doing, such as leaking a cursor or something? Could a
terminated process, due to Android wanting more memory or a crash, cause me
to be unable to open the database when the process starts again?
Should I be calling SQLiteDatabase.isOpen periodically or anything like
that?
