Yeah I don't bother ever checking if I'm in the UI thread or not, whenever it's an issue I just either spawn a new thread (for things I don't want on the UI thread), or I explicitly start the execution onto the UI thread. It's simpler to put it on the path you want then to check if you are already on it. I like the UI method were you do very little work on the UI thread. I like to return immediately from onCreate with something, but start a thread to do all my calculations, etc. At the same time I try to keep the number of threads low, basically one worker thread for each activity.

[android-developers] Re: What are the advantages of an Android Developers Device?
If you want to trace mass media hype driven by spending large sums of cash I suggest you compare how much Google has spent marketing Android with how much Apple has spent marketing iOS. I can't recall the last Google funded Android commercial I saw on TV. In terms of what platform you want to develop for, you may also wish to compare recent sales numbers for iPhone to recent sales numbers for Android devices. If you are more convinced by existing market share then current sales, I would suggest you compare either of those to J2ME and BREW device sales. While those 2 still greatly outnumber smartphones, there is nothing stopping Android from cannibalizing the feature phone market. On the other hand, if you want money NOW, and you want to be an independent application developer who depends directly upon immediate sales, it does make sense to do iOS development. If you can find funding, and are willing to accept a lower rate of return now, but an exponentially greater rate of return in the long run, I'd target Android. Either way, once you create an application that generates you some revenue, you'll want to port it to the other platform, and then to J2ME, Brew, etc. Uniwar is a good example of that.

[android-developers] Re: Is it possible to start an Activity from a non-context class?
Yeah thats what I usually do. I'm also a fan of static methods that get passed a Context object. You can also have your application or activities extend an interface, and have your methods expect that interface. The important thing is that your utility code trigger an execution thread, with access to the right context. I have a related question. What are the consequences, and best practices, of starting activities from a non activity context? The documentation says: http://developer.android.com/reference/android/content/Context.html#startActivity(android.content.Intent) Note that if this method is being called from outside of an Activity Context, then the Intent must include the FLAG_ACTIVITY_NEW_TASK launch flag. This is because, without being started from an existing Activity, there is no existing task in which to place the new activity and thus it needs to be placed in its own separate task. This seems to work, but I'm betting it has some interaction with http://developer.android.com/guide/topics/manifest/activity-element.html android:launchMode but that already confuses me... -MK On May 4, 8:42 am, Timo Prill timo.pr...@googlemail.com wrote: just pass your context over to the utility class via getter/setter or in constructor...

Thanks Mark. That really surprises me, but from examination of the API's I came to the same conclusion.

[android-developers] Re: OutOfMemoryError: how best to transfer large video files into a byte array?
I think you are on the right track. I have had very similar problems
in the past. For me the temporary file solution was obvious because I
had to modify the media before I uploaded it. Once you have a
temporary file, then you have the generic problem of uploading a large
file to a web server, and you aren't using don't need any Android
specific code.
It also makes it much easier if there are interstitial pages, multiple
activities client side that will need to access the temporary media
file, (perhaps to display a preview), and you can handle low memory
conditions better. The more Android development I do the more I find
myself writing to private local storage, to make sure I never lose
state.

Select a fixed buffer size first.
Then start writing the byte array to a file. Once the file size reaches the
buffer size configured, copy that file to a temporary location (a temp
file). Then transfer this temp file to the web server. Once transferred
successfully, make sure to delete this temp file (by calling deleteOnExit()
) when the file was created.
To make this work properly, there have to be 2 threads at work - the thread
that is writing the byte array to a file and the thread that is doing the
heavy duty stuff in the background - copy to the temp file location and
finally upload it to a server etc. This heavy duty thread waits on a
condition (waits for the file to reach the buffer size configured to start
the transfer).
I hope this makes sense...just sharing my thoughts aloud.

I suppose when you say FilePart, you mean this

//Implement your own PartSource to feed your File

FilePart part = FilePart(theFileName, partSource);
then use your part on your multipart request.
Thanks. Constructing a FilePart from a File is actually as easy as this, I
think - but do you think your method would provide some advantage?
File temp_file = new File(Environment.getExternalStorageDirectory(),
myfile.gif);
FilePart vFile = new FilePart(fileupload, temp_file);
As I say, this works for files of 50MB. The only reason I can't use it is
that I can't construct a File object from an Android content Uri. I have to
use an Android content Uri because that's what the video intent returns.
Ah. If I could transform my content Uri into FileInputStream (will have to
experiment) then I could use your method.
I can convert a content Uri to an InputStream already, so it'll just be
getting from an InputStream to a FileInputStream that might be the
challenge. I'll experiment.

I find that most of my problems are device or user specific issues. So to be useful, the unit tests would have to run on the actual hardware used by consumers, and would have to emulate the behavior of real users.

[android-developers] Re: Do Cursors provide write access?
Yeah getting the Android documentation updated would be one of my highest priorities. I waisted a day proving to myself it was wrong. My goal was to have a ListView, with items in the ListView grouped by first letter. Seemed easy, but the best way I could think of was to add 2 database columns, one with what grouping an entry counts as (in case we use a more complicated localized algorithm then the first letter in the string), and one with a groupingrank, which only matters for determining whether an entry is the first entry in a group.. I could not find a better way to do it then to go through each entry in the sorted cursor, calling context.getContentResolver().update( for any row that does not yet have it's grouping and groupingrank set properly. then in my ListView's Adapter I have a view which is invisible unless it is the first row in a group, and then it's group (the Letter A for example) would appear looking like a section header. So it would be A Aardvark Android Anteater B Bear C CyberBear M MutantCyberBear where A Aardvark is really a single row in the ListView.

Yea, trying to communicate between any two Androids, or any devices
for that matter, using their IP address is probably going to be next
to impossible, in the general case.
It would work OK inside an intranet where IP addresses are less
volatile (like the way controllers communicate with robots over a
local wireless LAN). Even then the devices are configured to have
predetermined, unchanging IP addresses.
Like Bob Kerns says you may way to consider using a server as
intermediary, much the same way that instant messaging works. A
reasonably dependable connection can be established between a server
and the Android and then the server can pass messages between the two.
If the Androids are in close proximity, like in the same small room,
take a look at Bluetooth for establishing a connection. That works
really well in such cases.
BTW, you can determine an Android's IP address like this:
public String getLocalIpAddress() {
try {
for (EnumerationNetworkInterface en =
NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
NetworkInterface intf = en.nextElement();
for (EnumerationInetAddress enumIpAddr =
intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
InetAddress inetAddress = enumIpAddr.nextElement();
if (!inetAddress.isLoopbackAddress()) {
return inetAddress.getHostAddress().toString();
}
}
}
} catch (SocketException ex) {
}
return null;
}
But it is mostly useless as it is usually known only to the nearest
DHCP server and not outside that sphere.
On Jan 28, 7:44 am, Bob Kerns r...@acm.org wrote:
The IP addresses will be whatever the DHCP server on that subnet says
they should be. Often, the DHCP server role will be handled by your
router to the internet, but in a corporate environment, things may be
more complicated.
When a device connects to an IP network, it usually broadcasts who am
I?, and a DHCP server then tells it basic stuff like it's IP address.
This can be a pre-allocated address assigned to that device, or it can
be allocated dynamically from a pool of addresses.
I would guess you don't want to require pre-assignment, because,
typically, users would not be able to do so.
So how do the devices discover each other's IP addresses?
Well, there are a lot of options there. You can have each user type in
the IP address. You can register the device dynamically under a DNS
server, and have them type in the DNS name. You can use a service
discovery protocol (like Apple's Bonjour service). You can roll your
own using broadcast or multicast messages. You can register each
device on a server -- and then even talk to each other THROUGH the
server. This last has the great advantage that it allows two devices
on incompatible networks to communicate. (I presume the disadvantages
are obvious).
About the only thing I can say for sure is -- you're going to need to
know more about networking than you do today. It's learnable, and
there are resources out there to help. Most of what you need to know
is information that is not specific to the Android platform, so there
will be a wide array of sources of information. Google searches are
you friend.
You can probably accomplish everything you're trying to do entirely
with the classes in the java.net package. So you can develop your
approach in any connected Java environment.

[android-developers] Re: Null pointer exception
I do the management in onStop, for my cursor which supplies the data
needed by a ListView (which means the cursor has to be open whenever
the activity is displayed).
@Override
protected void onStop() {
super.onStop();
if(db!=null){
if(db.isOpen()){
db.close();
}
}
if(mCursor!=null){
if(!mCursor.isClosed()){
mCursor.close();
}
}

What do you think about this:
1. Cursor created in onContextItemSelected() is null (for some reason)
2. Since its lifecycle is managed by the activity (startManagingCursor
(c)), it tries to release it when the activity is stopped (when the
new intent is launched)
3. It doesn't expect managed cursor to be null and crashes (at
android.app.Activity.performStop(Activity.java:3604))
Does that make sense? I have little idea about how this cursor
management works, but I would do the following:
1. Try removing startManagingCursor() calls to see if these are
related
2. Double check if the cursor is null
3. Take a look inside Android source and specifically Activity.java:
3604
Just a guess :)

I do get the impression most game developers ignore most of the Android specific stuff.

Garbage collection is your enemy for real time games. So for RT games you'll want to create nearly all of your objects up front, and thus attempt to avoid garbage collection.

[android-developers] What does targetSdkVersion do?
What does targetSdkVersion do? There isn't much detail on what targetSdkVersion actually does. I've read: http://developer.android.com/guide/topics/manifest/uses-sdk-element.html#target android:targetSdkVersion An integer designating the API Level that the application is targetting. With this attribute set, the application says that it is able to run on older versions (down to minSdkVersion), but was explicitly tested to work with the version specified here. Specifying this target version allows the platform to disable compatibility settings that are not required for the target version (which may otherwise be turned on in order to maintain forward-compatibility) or enable newer features that are not available to older applications. This does not mean that you can program different features for different versions of the platform—it simply informs the platform that you have tested against the target version and the platform should not perform any extra work to maintain forward-compatibility with the target version. Introduced in: API Level 4 I'm curious because it appears that switching from: uses-sdk android:minSdkVersion=3 android:targetSdkVersion=4/ to uses-sdk android:minSdkVersion=3/ is the change that started the android.view.InflateException ... java.lang.OutOfMemoryError: bitmap size exceeds VM budget errors I was randomly seeing in setContentView.

[android-developers] Re: Upload multiple versions for single android application for different SDK levels 1.5, 1.6, 2.0
An Android developer has to develop the habit of untraining management that is used to J2ME. If you release multiple different APKs you technically can fork your codebase, into different packages, to target different firmware. But you don't want to compete with yourself for market listings, you don't want to fork your code, you don't want to have to maintain different branches. Mind you, I don't want to use reflection, it frightens me a bit, and it's annoyed me and made my app harder to debug every time I've used it. Eventually though we'll really want to use a feature not in 1.5. I'm curious, what happens if you release an application that requires Android 1.5 or higher on the market, and then you update it with a version that requires 1.6 or higher? Will 1.5 users simply no longer be able to download the application? What is their user experience? Thanks, -MK On Dec 18, 2:42 am, lk vaish.alo...@gmail.com wrote: hi TreKing Thanks for your reply.

I don't imagine anyone is going to take the time to write the code solely to post it here, so if you can just point me in the right direction it would be greatly appreciated. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: GK:How to Kill all Activity at a time ?
I've implemented a Sign Out function before which was much like exit
except we still wanted the initial login screen to display. You can
try to open your activities with startActivityForResult and in
onActivityResult check if you were sent an exit code you chose, then
call finish in every activity. Lots of things can cause this to
fail though.
I find I typically have a ThisApplicationsActivities parent Activity
that most of my activities will inherit from. So to implement
SignOut you change a static variable to indicate you've signed out,
and in onResume of this master Activity class check if the user is
currently logged in, and if not call finish(). This worked fine for
me.

Any other try ? ?

Hi Ganesh,there are two ways
android.os.Process.killProcess(android.os.Process.myPid())
System.exit(0);
I normally use the second, I agree that some times you just want to
properly exit an app as you dont want it using memory and slowing
your phone

Press HOME, and you're done. Moreover, that's what Android is trying to
teach users to do -- press HOME, and they're done.
Remember: everybody keeps holding iPhone up as perfection for user design,
and applications there do not have normally an exit option AFAICT. Users
just press The One And Only Button, and they're done. (Note: my iPod Touch
hasn't been, er, touched since before the OS 3.0 upgrade, so perhaps they
changed their UI approach recently and I missed it).
So, just make sure your app behaves the way you want when the user presses
HOME, and you're done.

[android-developers] } catch (OutOfMemoryError E) {
Can I ask what Android does with un caught OutOfMemoryErrors that it
wouldn't do if I caught them? It's really tempting for me to do this:
try {
setContentView(R.layout.result);
} catch (OutOfMemoryError E) {
outOfMemoryCount++;
e.printStackTrace();
finish();
}
If I don't catch the OutOfMemory my activity crashes, but then the
user just clicks the button again and it loads great the second time.
So something happens resulting in the right memory being cleared.

My guess is that the app goes into pause mode and when restarted since
I was reattaching the same animation to the ImageView it was causing a
leak.
Note this ImageView and Animation were not static variables they were
loaded only on the onWindowFocusChange event. I made the assumption
since I was not letting my ImageView and Animation be created as
static variables I wouldn't leak the Context, but apparently the
recreation of the animation attachment to the ImageView was for some
reason, this I'm not 100% sure on, but it seems to be the case.

I tried: http://developer.android.com/reference/android/app/Activity.html#startManagingCursor%28android.database.Cursor%29 but at best it throws ugly log messages. So I'm implenting onPause, onResume etc to manage it myself, which is annoying for a ListView since ListView seems to need my cursor open. Really I just want to materialize the view, and re fetch it on resume, not leave an open database connection, it's a tiny database since every row in the database is reflected in the UI (so it crops to 10 items).

[android-developers] Re: AnimationDrawable and Out of Memory Errors
Got any advice on tools to use to debug the most likely situation

immensely. It beats re writing every class.

As I understand it if you do

javac will strip the doStuff call since it's known to be unreachable

I don't get it. If you're nulling your static bitmap in onPause why is it static to begin with?

[android-developers] Re: HTML sanitization
http://d.android.com/reference/android/text/Html.html This lets you put sanitized html content into a textview. It's great for clickable links or styled text with inline images if you aren't too picky about where the image ends up. It's going to basically treat each image as a character in the textfield, in terms of how it looks. The sanitized html is returned as a Spanned: http://d.android.com/reference/android/text/Spanned.html which is a really useful class, and this is a good way to start using it. Often if I want to display simple stylized text the easiest way I can find is to create some simple html, and use the above method. It's weak on properly wrapping text around the images, you can have one line of text to the left and or right of an image, but you can't wrap multiple lines around, so a lot of white space will be created with tall images. -My 2 cents On Dec 4, 1:02 am, Samuh samuh.va...@gmail.com wrote: The best way I can think of getting around this problem would be showing your HTML content inside a WebView. :) Thanks for your reply Bibek.

[android-developers] Re: java.lang.OutOfMemoryError: bitmap size exceeds VM budget
My app involves taking a picture with the camera, or recording voice using the microphone, and sending the results to the server. It's a search tool. The UI isn't very complicated, as much as possible it is done in XML. For the droid we added some layouts in res/long that differ only in layout margins. I, like a great many Android developers, had to re create the look and feel that was established with our iPhone application. On the droid we had gradient banding so we pre dithered a png, but that was the art guy. The layouts could be simpler, but I have already repeatedly simplified them from the first version that had the right look and feel. I have some FrameLayouts, containing RelativeLayouts, containing single Views. It seems like RelativeLayout has been redone and is less brittle then I remember it, so I probably can start skipping the FrameLayouts. Framelayouts just seem like the simple easy way to control over lap of views, and I often have 4 over lapping views. I also have some linear layouts in side other linear layouts, but all with different weights. The 1 or 2 pixel differences between 1.5,1.6 and 2.0 make our application look worse on the Hero. I use ListViews, that sometimes are populated by CursorAdapters. I have gone back and forth between letting the activity manage the cursors, and managing them myself. (I'm referencing AdMob and other's numbers to try and figure out what Android versions I need to support, and what handsets I need to test on http://daringfireball.net/linked/2009/11/23/admob ) Much of the code for my app was written for Android 1.0, 1.1 etc. and it has been maintained by different developers over the years. Now I guess my task is to go over every line of code and reduce how much memory is used. I've tried to check every static reference that wasn't a private static final constant primitive, to make sure we weren't hindering garbage collection. I don't think I ever store a context, but we pass them around everywhere as arguments. I can't really recycle my drawables because I'm not managing them, I just call setContentView. My activities have some member variables, views, etc. I create some handlers, but more often just call runOnUiThread. I guess I can explicitly set these to null in onStop... when I hear improve memory management my first response is to set things null, my problem is the unusual lifecycle of an Android application, it's activities, and it's static variables. I'm already prepared for my major static variables, strings, to unexpectedly become null, and write my strings to a private preference, or save my camera or microphone content as a private application file. It's all pretty vanilla. The networking is done using some included apache jars, I guess I could redo all my networking to use something else, that would make it even more vanilla. But I will probably wait until my application becomes less vanilla and we need a push solution. SoftwareForMe, I have read your post a couple times now, I think it's clear to me now. Generating a new version of most or all of our PNGs, especially our largest, sounds like a good idea. Is there a good blog post I can send to the art guy so he can understand what he needs to do? I'd like not to have to go 11 more revisions on each asset. It'd be real cool if there was an easy way to just remove all my unused PNGs from my project, before I double them. I have not go through and removed every PNG that is no longer being referenced yet. My 2 cents, Matt Kanninen Android Developer On Dec 2, 8:38 pm, SoftwareForMe.com SoftwareForMe.com softwareforme@gmail.com wrote: The bitmap issue on the Droid is really about whether you want to show more graphics at smaller size, or the same graphics at larger size. I don't know what you app does, but imagine that it's a 2d game, where the graphics are re-used a lot (land tiles, character icons, etc.). If you let the higher resolution screen show more of the game map at a time, your program will consume NEARLY identical memory to what it would on other devices. Why? Because the tiles will be the same size in memory; the only thing that would be larger would be the screen surface, and any back buffers you use. On the other hand, if you want the graphics on the Droid to look the same (same game play area visible), then without work, your application will take more memory on the Droid. Why? Because unless you explicitly avoid it, Android will scale your image up to higher resolution when you load them, so they take more memory. The solutions are to: 1) Create high-density images that are simply smaller, but occupy the same number of pixels. This way, loading resources on the denser devices won't take any memory, or 2) Resize the images after you load them, understanding that loading the exact same resource on two different devices may result in two different sized bitmaps in memory Of course approach #1 is the standard

I think you next need to display your canvas. It does not appear to
be attached to your view hierarchy, that I can see. You setContetView
main, but I don't see you attach to any views.

I recommend you don't display anything to the user until the next time they run the main application, and on first run of the main application you congratulate the user on the upgrade. You could go over board and add more code to the main application to test for the existence of the second application, going so far as to add a service in your main application, that checks for the existence of upgrades. Android lets you go over board :) -My 2 cents On Dec 3, 9:51 am, Mike michaeldouglaskra...@gmail.com wrote: Here's my use case that will hopefully explain why I even want to do this: 1) I have a free app 2) I wrote another app that serves strictly as a token which the user can purchase to upgrade features in the free app 3) When they purchase the upgrade app, I want to give them the impression they actually downloaded it and it installed correctly. Simply having it install without any confirmation will, I assure you, result in countless emails to me. 4) I really don't want to have to show the upgrade app in their app tray since they now would have two icons.

[android-developers] New SDK!
As I wait for it download I'll enjoy the documentation. I'm particularly excited about: http://developer.android.com/guide/developing/tools/layoutopt.html layoutopt layoutopt is a command-line tool that helps you optimize the layouts and layout hierarchies of your applications. You can run it against your layout files or resource directories to quickly check for inefficiencies or other types of problems that could be affecting the performance of your application. To run the tool, open a terminal and launch layoutopt resources from your SDK tools/ directory. In the command, supply a list of uncompiled resource xml files or directories that you want to analyze. When run, the tool loads the specified XML files and analyzes their layout structures and hierarchies according to a set of predefined rules. If it detects issues, it outputs information about the issues, giving filename, line numbers, description of issue, and for some types of issues a suggested resolution. Here's an example of the output: $ layoutopt samples/ samples/compound.xml 7:23 The root-level FrameLayout/ can be replaced with merge/ 11:21 This LinearLayout layout or its FrameLayout parent is useless samples/simple.xml 7:7 The root-level FrameLayout/ can be replaced with merge/ samples/too_deep.xml -1:-1 This layout has too many nested layouts: 13 levels, it should have = 10! 20:81 This LinearLayout layout or its LinearLayout parent is useless 24:79 This LinearLayout layout or its LinearLayout parent is useless 28:77 This LinearLayout layout or its LinearLayout parent is useless 32:75 This LinearLayout layout or its LinearLayout parent is useless 36:73 This LinearLayout layout or its LinearLayout parent is useless 40:71 This LinearLayout layout or its LinearLayout parent is useless 44:69 This LinearLayout layout or its LinearLayout parent is useless 48:67 This LinearLayout layout or its LinearLayout parent is useless 52:65 This LinearLayout layout or its LinearLayout parent is useless 56:63 This LinearLayout layout or its LinearLayout parent is useless samples/too_many.xml 7:413 The root-level FrameLayout/ can be replaced with merge/ -1:-1 This layout has too many views: 81 views, it should have = 80! samples/useless.xml 7:19 The root-level FrameLayout/ can be replaced with merge/ 11:17 This LinearLayout layout or its FrameLayout parent is useless The layoutopt tool is available in SDK Tools, Revision 3 or later. If you do not have SDK Tools r3 or later installed in your SDK, you can download it from the Android SDK repository site using the Android SDK and AVD Manager. For information, see Adding SDK Components.

[android-developers] Re: java.lang.OutOfMemoryError: bitmap size exceeds VM budget
The app worked great on the G1. I've clearly hit a case where the

Droid.
The bitmap out of memory errors can still occur on any setLayout(res/
xml/id), after running the app for 5-30 mins. But I did fix the
bitmap out of memory crash that occured during
glow.setBackgroundResource(glowDrawableIds[scale]);
We just don't set a new background resource anymore.
I had 10 animation frames, and the animation frame chosen was based
upon the volume coming from the mic.
Now we take what was the last frame, and vary it's drawable's
transparency depending on volume.
glow.getBackground().setAlpha(alpha);
I will now start creating additional res/xml/files, so that LESS
complex layouts are used on the Verizon Motorola Droid with firmware
2.0 then we used on the G1.
The layouts, and the final resulting screens were approved by
management, so I will be trying hard not to change ANYTHING on the G1,
while adding support for the inferior memory handling on the only
Android 2.0 handset. The one with better specs.

[android-developers] Re: java.lang.OutOfMemoryError: bitmap size exceeds VM budget
The same code works great on the G1 and the MyTouch. We've done some
testing on the Hero, and the Moment, but only on the Droid is the
issue significant. I've told my boss that I am spending time porting
to the Droid.
You have explained that bitmaps are scaled and require more memory.
This creates a stricter limitation, on the complexity possible for my
xml, on the frequency with which I can create bitmaps, etc.
It's a bug if an application works on phones A, B, C and D, but not
E. My first instinct is not to blame the guy who wrote the
application, but the guys responsible for handset E's software. In
fact situations like that are the textbook case for a bug with handset
E. Especially if handset E is newer, or running a newer firmware then
handsets A, B, C and D.
I think this is a big deal, especially given the fact for a lot of
users and non users, Droid -- Android. I'd consider it a priority
to make sure that G1 applications can run on the Droid.
Extensive googling didn't lead me to a lot of other people
complaining, so I may be one of the unlucky few who happens to use the
exact amount of memory such that it works on every phone but the
Droid. I'm not unfamiliar with that sort of luck :)
Extensive googling did lead me to old posts I remember reading the
year they were written, and I remember being suprised by how Bitmap
memory was handled then.
