[android-developers] Re: How to check the Foreground Process from a Service
Does anyone know how to, or if it's even possible to check the (foreground process/top of the activity stack) from a service? It is possible, see the ActivityManager class functions like getRunningAppProcesses(). getRunningTasks() looks useful but is flakey in my experience e.g. when you return to the launcher it is sometimes not updated.

[android-developers] Re: Android and Proguard
As far as I could work out, no. ProGuard needs to be inserted into middle of the build process, and while ant lets you do this, Eclipse does not (at least, not for someone at my level of expertise). It seems likely Google will integrate ProGuard into the Eclipse plugin at some point, but that hasn't happened yet. Personally, I gave up on ProGuard - after several hours of messing around - when it threw several hundred errors on my app. I also am not impressed with optimization that makes my stack traces worthless, thank you very much.

[android-developers] Re: Optimizing image processing algorithms for Android
Hi, As per the last msg on this thread, I did check out about GC pre- empting the CPU/locking up the thread. As I said, I hadn't considered this possibility, and I wasn't aware of it either, to be honest. I googled around to check out more on it, and came across another thread on the forums http://groups.google.com/group/android-ndk/browse_thread/thread/6bc6b9b0c3540c27 I believe the same thing is happening in my case: except that I am doing image/video processing as opposed to the audio processing that this thread above concerns. Will post back/share as I learn more.. Another related stuff is I was checking out some docs relating to writing efficient/optimized code for ARM11 architecture. For the record, the processor I am running my stuff on has the ARM1176JZF-S which has independent I/D caches of 16 KB each and two TCMs (Tightly Coupled Memories) also of 16KB each... I did some tests on a simple loop which I was using to define my image data (one naive code vs. ARM code) but did not notice significant difference... What is more is that the profile time varies significantly. I checked the logs to see what the GC is upto and sure enough you see the GC thread doing its stuff... So I guess I am going to tackle this more basic issue first, and then think about optimizing the C code :) thanks, Amit On Aug 20, 2:35 pm, Amit prabhudesai.a...@gmail.com wrote: Hi, Thanks for your reply This sounds all find and good, but I still haven't heard anything about the far more common cause of delay: the garbage collector locking up the thread or pre-empting the CPU.

If you use one of these, you are guaranteed word-alignment on the ARM. NB: I say jsr-239 java.nio because there may be subtle implementation differences between those and the original java.nio classes. For example, JSR-239 does not expect flip() to be useful, nor is supporting Mark required.

The memory optimizations can be huge. I remember one project the speed more than doubled once we only using cache memory. That is the entire working data set was less than 8k. The process is fairly straight forward: Determine the size of your cache, then use only that much memory. This typically requires doing tricks like making the output buffer overlap the input buffer. Basically you need to know exactly where every byte of memory is being used. Java tends to be allocate as you need memory model, but for cache optimizations you need tighter control of memory usage.

And even more improvement by packing the Char array owned by a String into the String and arranging it so that the two shared a single header.

[android-developers] vibrate() does not behave according to API docs (HTC Desire)
Hi folks, I'm trying to get a simple vibration working and according to the api docs (http://developer.android.com/reference/android/os/Vibrator.html) all I need to use is this: public void vibrate (long milliseconds) Turn the vibrator on. Parameters millisecondsHow long to vibrate for. However the behavior I am seeing is not what is described. Instead of a number of milliseconds, it seems this parameter translates into an intensity?? I tried: vibrator.vibrate(200); and I got a sustained vibration which didn't stop until I exited my app. Initially I thought perhaps the api docs were wrong and the parameter was seconds, not milliseconds, so I tried: vibrator.vibrate(2); This time I got the same behavior, i.e. continuous vibration, but the vibration was very gentle.. almost in-perceptible. This leads me to conclude that the parameter translates into an intensity, not a time. Is it possible that this is a feature of the particular device? In my case HTC Desire. I'm running 2.1 as my crappy telco hasn't distributed an update to 2.2, but it worries me that this behavior may differ from device to device.

[android-developers] Re: connecting mysql database
I think it is rather presumptuous of some commentators to suggest one approach is either right or wrong. The real world is never this black or white. A direct connection to a remote database is perfectly secure, usable and technically possible particularly if the Android device is connecting via a secure wi-fi network or a GPRS/3G network where the SIM is part of a private APN. Unlike J2ME for example, the Android framework supports full database JDBC connectivity. Android also supports many technical solutions to supporting offline connectivity that does not just involve REST and web services. Our MobiForms Developer rapid application development tool for example supports the creation of apps that can directly connect to a multitude of back office databases via JDBC. We do not currently support MySQL in this direct mode, but this is a licensing issue rather than a technical issue. The complementary MobiForms Sync Server also supports bi-directional data replication, synchronisation and offline buffering between just about any back office database or ERP package (such as Oracle Apps, SAP, Navision, Dynamics etc.), and Google Android or others such as Windows Mobile. Supported back office databases include Oracle, SQL Server, Access, Sybase, IBM DB2, SQLite, HSQLDB and MySQL For more information go to: http://www.mobiforms.com. crajesh wrote: Hi All, I am new in android.

[android-developers] Re: Empty Spinner before first selection
Thanks, though I wasn't confused about which Listener I needed to set
in order to respond to a selection from a user.
Nor how to ignore the initial selection using a switch in that
Listener (though that is something that is also annoying).
I was hoping to use those Listeners to switch from a null Adapater to
my real Adapter prior to displaying the DropDownView so it would
1) only show the items that are truly available for selection
2) not show any selected item prior to DropDownView.
It seems strange that a ListView can have no items selected via
#setSelection(-1), but a Spinner cannot.
It all hinges on the code in AbsSpinner#setAdapter
if (mAdapter != null) {
...
mItemCount = mAdapater.getCount();
int position = mItemCount 0 ? 0 : INVALID_POSITION;
setSelectedPositionInt(position);
setNextSelectedPositionInt(position);
...
}
which selects the first element in the Adapter when the Adapter is
set. But if it was
if (mAdapter != null) {
...
mItemCount = mAdapater.getCount();
int position = INVALID_POSITION;
setSelectedPositionInt(position);
setNextSelectedPositionInt(position);
...
}
then initial selection of the Spinner would be configurable instead of
always being the first element.

Subclass Spinner, override setAdapter() to behave how you want, and use it.

[android-developers] Calling the stop() function of MediaPlayer
Hi! I don't know if I'm doing something wrong, but I see calling the stop function of MediaPlayer simply does nothing. The playback goes on. I looked in the documentation and I found: Stops playback after playback has been stopped or paused. So, I tried to pause() it before stopping, but the MediaPlayer then pauses and resumes the playback. The only thing I can see is that the buffering stops. But the playback continues. Is this the expected behavior? Could the problem be related to the fact that I call the methods of the MediaPlayer object from different threads than the creator by synchronizing with Semaphores?

[android-developers] Re: Best way to scale for different screen resolutions/dimensions?
The problem, and it may be that I'm misunderstanding how Android handles different screen sizes, is that when trying to incorporate the material found on the Supporting Multiple Screens developer doc, it appears to always display in compatibility mode. If one has a custom layout, or a SurfaceView, and wants to build for HVGA, is there a way to have the OS scale everything nicely when used on other sized screens? Is there a place to define the intended layout or SurfaceView dimensions that are used as the basis for any automatic scaling the OS does (if indeed automatic scaling is possible)? I'm just confused on the process to use and the settings to set. Since all drawing will be custom, similar to a game concept drawing bitmap objects directly, it just seems a little different than if there was a UI with widgets.

[android-developers] So can we use Directions API or not in Android?
I would love to be able to use the Directions API in my Android app, but I'm confused by the information in the Directions API documentation: http://code.google.com/apis/maps/documentation/directions/ so the short form of my question is: can Android apps use the Google Directions API? It clearly states the intended audience includes mobile developers. But it also states that you're limited to 2500 requests per day. Does this mean my app, if deployed to thousands of devices, is in total restricted to 2500 requests per day? How could the Google server tell anyway? Based on IP address? In which case I may be okay. The docs also say no API key is required so again it would seem the Google servers have nothing to use to accumulate a counter of requests per day. Still, I don't want to be in violation of any Google Terms of Service. So is it okay or not?

[android-developers] Re: Must pass Context to other classes?
Yes. The more you find that you are doing this, the more you have over-engineered your object model, IMHO. I don't know, I would actually argue the opposite. IMHO, any object that doesn't need a Context or one of its super or subclasses, is not really targeting the Android platform. The Android specific code can obviously factored out of any class using the Strategy patttern, but I think that just complicates the design and mostly a useful exercise only for cross-platform libraries. It would also requiry violating MY first rule in an AndroidStrategy class: - I never EVER store a Context family object as a member of a class -- I always pass it as an argument. This is to avoid accidentally leaking the context. - The above is true for cases when inner classes need the context, like UI event handlers. In my app, for example, there is a CopyUI class. This CopyUI is comprised of a few dialogs -- it may prompt for a file name, or it may pop-up a warning that the file already exists and it also displays a spinner while copying. The method CopyUI.show() takes a Context, but it's never stored in a member, but instead, it is made final and passed around from dialog to dialog. - I always pass the most appropriate context. For example, if I need to retrieve a string only, I only pass a Resources object. This is more a self-documentation style, than a real requirement, though. -- You received this message because you are subscribed to the Google Groups Android Developers group.

and should appear above the other viewport showing a cube. Now, when i
have both viewports active I cannot see the white polygon but the
smaller viewport with the cube. In case I have the second viewports
code in block comments it again apears. I don't get where I have to
modify the code that both viewports appear correctly on the emulator.

}
}

[android-developers] Re: Running JUnit 4 Tests on Android Device
Just put the JUnit 4 jar before the Android jar in the classpath. This will hide the JUnit 3 classes. Note that you must not use any Android classes in your test! You will get Stub! exceptions if you do. If you need a few basic Android classes in your tests (like Intent and Bundle), add simple replacements to your test folder. Try to separate testing close to Android with the Android testing framework (JUnit 3 based), and core logic without Android framework dependencies (using JUnit 4) and you're good to go..

Re: [android-developers] So can we use Directions API or not in Android?
As far as I know, the 2500 requests per day is for all applications out there (be it desktop, mobile or whatever), so your application really can't rely on this directions API since it can be brought offline in less then an hour by all the applications using it. (And in my opinion that's why noone is using it for anything but debugging.) 2010/8/22 davemac davemac...@gmail.com I would love to be able to use the Directions API in my Android app, but I'm confused by the information in the Directions API documentation: http://code.google.com/apis/maps/documentation/directions/ so the short form of my question is: can Android apps use the Google Directions API? It clearly states the intended audience includes mobile developers. But it also states that you're limited to 2500 requests per day. Does this mean my app, if deployed to thousands of devices, is in total restricted to 2500 requests per day? How could the Google server tell anyway? Based on IP address? In which case I may be okay. The docs also say no API key is required so again it would seem the Google servers have nothing to use to accumulate a counter of requests per day. Still, I don't want to be in violation of any Google Terms of Service. So is it okay or not?

Answering my own question here. I solved it and in my case the problem was that my Google account on the phone wasn't set up to sync and do background data.

I'm probably not the only developer that needs to try C2DM on the emulator so a solution to this could be quite useful. First of all let me say that I'm running the latest Google APIs 8 rev 2 as AVD which should have all the necessary magic to allow me to run C2DM (it even has all the market components to run the LVL). I tried both Chrome to Phone and Jumpnote and it was impossible to make the C2DM service work. - Chrome to Phone fails when trying to connect from the Android app running on the emulator with a Error: Unable to connect. On the Chrome to Phone site they recommend that Talk should be tried first and that the Market should be available (none of these come in the emulator image and I'm not sure if I should even try to install them on the emulator). - Jumpnote does not synchronize automatically and gives me an error: Error calling remote note sync RPC (when I do a manual sync I can see the docs being synchronized but looks like C2DM, which enables the auto sync, is broken). I also heard a comment that maybe port forwarding via adb could be necessary (but I'm really not sure this makes any sense). So can anybody confirm or deny that C2DM enabled apps can be run properly on the emulator? (eg Jumpnote, Chrome to Phone). How can I test C2DM on the emulator? Alternatively, does anybody know of an AVD image with all features on it? (full Market, Talk, etc) Best!! Thx in advance.

Sure, you need Context pretty much everywhere the UI and other Android specifics are concerned, but your core objects that represent the general layout of your application should not know anything about what a Context is or have any reason to use it. Just because Context is usually readily available (in your Activity or Service) does not mean you should force arbitrary dependencies on it. The Android specific code can obviously factored out of any class using the Strategy patttern, but I think that just complicates the design and mostly a useful exercise only for cross-platform libraries. I think (a variation of) MVC is more appropo in this case and definitely simplifies things, IMO. Example: in my app I have a Bus object. This has absolutely no reason to know about Context or the Android platform in general. However, when I, say, plot a bus on a map, it's *view* knows about the bus and how it should be displayed, using the current Context.

Hi From the TabWidget example in the docs, this is what the tabs look like in v1.5/1.6: http://developer.android.com/resources/tutorials/views/images/hello-tabwidget.png As you can see, the TabIndicator is white, with the icon in grey. In v2.x the TabIndicator is no longer white, but grey. This, then, leads to the issue of the tab's selected/unselected icons not being visible on one platform or the other (i.e. if the icon is white, it won't show up on the white background in v1.5/v1.6 but is OK on v2.x and vice-versa). So, my current thoughts are to essentially flip the icons and put them in resource directories specific to the platforms (i.e. using the v3 and v4 qualifiers). Is there another workaround that I'm missing? Cheers James -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: connecting mysql database
In other words, eat cake. On Aug 21, 6:26 pm, Bob Kerns r...@acm.org wrote: Re: This is a limitation/shortcoming/feature of Android. No, it's not. It's a characteristic of SQL database connections, vs the characteristics of distributed clients. This is not new with Android -- well-written desktop applications use a service layer rather than direct connection to the SQL database. There are many, many very important reasons for this, from performance and scalability to network reliability. But to my mind, the single most important reason for it is this: If you change your database schema for whatever reason, you are not able to force all of the clients to synchronously update to use that brand-new schema. Yes, you can use views, triggers, and such to try to mask such changes, but they're both extremely awkward to maintain and quite limited, and often negate the very benefit you wanted to achieve with the schema change. I would even agree with Miguel's formulation, that Any decent developer should know this -- if you take it as advice. This is core architectural savvy that if a developer is not familiar with, he should seek to remedy. And -- despite it not being useful in this way -- I would also say that a solid knowledge of SQL is something any well-rounded developer should acquire. Put them on the list with all the others...

When the app starts up it shows the activity label property in the title bar. If you set a different title for the activity in onCreate that will show up later. You see the launcher activity title for a while and then the programmatic title replaces it, which is not very nice visually. The icon on the home screen uses the label for the activity. What I'm trying to do is get a label for the icon on the home screen that is different from the activity title bar. I tried setting the intent- filter label, but that didn't appear under the home screen icon. There is a label property for the application, the activity, and the intent-filter.

[android-developers] Re: Android and Proguard
To integrate an Ant build step into your Eclipse project, go to the Builders section in the project properties, and add an Ant builder, tell it what targets and when to run them, etc. You get to tell it what changes trigger it, and what changes it produces. But I wouldn't recommend integrating ProGuard into a development build process, for any number of reasons. Nor would I do production builds with an Eclipse-based build process, for an entirely different set of reasons. If you use Proguard correctly, it doesn't mess up your stack traces, it obfuscates them, and you then unobfuscate them when you need them. You can set that up to be pretty convenient, but it's not as convenient as reading the trace in an email and instantly knowing the problem -- you'll have to feed it to the stack trace unobfuscator first. Using it correctly that way requires a certain amount of effort, planning, and discipline. That can be more of a distraction than the value it adds -- as can the learning curve, as you experienced. As an indication of where I stand on that -- I have yet to apply Proguard to an Android project. I expect it would take me a couple of days of fiddling and testing and build engineering and testing and setting up the tracking of the data for deobfuscation, and more testing etc. If it's your first Proguard project, I'd suggest allowing a week for a small project, or two for a large one. If obfuscation, or optimization, are worth that size investment, go for it. But don't do it just because it's there, and you want to keep your code secret. On Aug 22, 12:24 am, String sterling.ud...@googlemail.com wrote: As far as I could work out, no.

[android-developers] Re: Adding a contact without a READ_CONTACTS permission
Giving the program permission to write what it cannot read sounds like a recipe for trouble. If anything, I would expect the finer granulation of permission to go exactly the other way, i.e. granting permission to read contacts w/o permission to write them. But we don't get that either. Not having it still sounds to me like a small loss, though. Writing what you cannot read is like painting your windshield black before driving your car out of the driveway. I can do without permissions for doing that. If a program asked for such permissions, I would assume the author was crazy. I can think of use cases for reading contacts w/o write permissions, but they are not THAT compelling. So I can see making it a feature request, but I can't see expecting a very high priority for it. After all, it seems Google was more concerned about someone reading your contacts to get your private information than they were about a malicious program writing bogus values to your contacts (though I can see that as an attack vector too). On Aug 22, 9:06 am, Pinheiro rui.c.pinhe...@gmail.com wrote: It is very hard to ensure that someone with write access can't also get data back from the provider, so generally no.

[android-developers] Button State does not toggle automatically!! Help!
Guys, I am trying to get the button in my layout to have focus as I am programmatically changing its state. My application is a video player using VideoView. I am toggling the state of the button based on where my video is. So basically, I am doing videoview.getCurrentPosition() and if it is in a certain window, I want to toggle my Button state (enabled to disabled and vice versa). The layout is LinearLayout and I have the VideoView and Button layed horizontally. When I first had the MediaController in my Video, the button would change focus on touching the videoview (which is when the MediaController would pop up). I later removed the controller because I didn't want the button state to change when the user touches the screen. I want it to change automatically. I tried all sorts of combinations possible. button.setFocusable(), button.requestFocus(), button.bringToFront() and so on. But none of them seem to work. Is there any way I can make it toggle programatically and without user intervention through touch? or is it impossible to do it with the VideoView?

[android-developers] Strange ActivityNotFoundException
The error I receive is, android.content.ActivityNotFoundException:
Unable to find explicit activity class {com.droidea.birthday/
EditBirthdayActivity}; have you declared this activity in your
AndroidManifest.xml?
The error seems simple enough, but I don't see a problem with the way
I have identified this activity in my manifest file. I have also been
unable to see any problems with the activity class itself.
Code:
AndroidManifiest.xml:
activity
android:name=com.droidea.birthday.EditBirthdayActivity
android:windowSoftInputMode=stateVisible|
adjustResize
/activity
Activity call:
Intent intent = new Intent(Intent.ACTION_INSERT,
People.CONTENT_URI);
intent.setClassName(com.droidea.birthday,
EditBirthdayActivity);
startActivity(intent);
The EditBirthdayActivity is public, and I can see the activity from
Dev Tools - Package Browser using the emulator.
I have spent several hours trying different configurations, but I'm
spinning my wheels at this point.
Has anyone experienced this?

Re: [android-developers] Re: How to get absolute time ?
I assume you are trying to get current UTC time for purposes of DRM, such as expring a trial license. From what I can tell on my Droid, there are two ways the system time is set, automatically and manually. I'm pretty sure manually can be used to defeat time-based DRM, as it has been on desktops for years. If your app can tell if the time is automatic or manual, you could require that it be automatic to run your app. The other way is to make a network request to a trusted time server. Even that can be defeated, but requires more effort in networking than a typical hacker would probably find worthwhile. The other problem with this approach is what do do when the network is unreachable. If the app requires network access to function anyway, then OK. Otherwise, there's probably some reasonable way to validate the app during network unavailable times. BTW, local time has nothing to do with this problem, if you implement it correctly. -- You received this message because you are subscribed to the Google Groups Android Developers group.
