Re: [android-developers] Re: Activity without UI
In activity that doesn't UI should finish itself by the time it returns from onResume(). Leaving an activity running without UI will result in various kinds of undesirable behavior.

I have not any idea about Binder concepts. So I could not find out
exact reason for the issue.
Since I need to resolve this issue urgently, I have delved more and
find out, the exception is in this method:
frameworks\base\core\java\android\bluetooth\BluetoothDevice.java -
public int getBondState() {
try {
return sService.getBondState(mAddress);
} catch (RemoteException e) {Log.e(TAG, , e);}
return BOND_NONE;
}
Here this method catches the remote exception, but in catch statement
just prints the exception, but does not return anything.
I understand if I return something from catch statement then this
problem will be solved.
But the point is what to return at that statement?
I understand this class is used at many places, and returning anything
will impact other aspects also.
So please suggest me what should I return from here.
If you have any other solution for this problem, please suggest that
also.

H-m-m-m. Interesting point. Emulating a 1Ghz CPU on a 2Ghz CPU is bound to be slow. But given that, I would be still be happy if the emulator were only 1/25th the speed of the emulated system (I have dealt with worse). It is still, after all, faster than waiting for a developer version;) On Feb 24, 8:33 pm, Zsolt Vasvari zvasv...@gmail.com wrote: I second this. The emulator is unusable for Xoom and I wouldn't hold ny breath for any significant improvements in the speed of the emulated machine, no matter what Romain is saying. Even if they manage to double the speed of the emulator, it would still be pretty much unusable. You will never be able to satisfactorily emulate a 1GHz processor on a 2GHz processor of a completely different architecture. What Google should do is sell a developer version of Xoom, like they do with Nexus One, perhaphs a 16GB WI-FI only version. Until then, I doubt too many indy devs would make a Honeycomb version of their apps.

And since I find it really, really hard to believe that the cause of this problem is just String's own cockpit error, I will not be loading the latest SDK because of that report. I am sure lots of other people will be having a similar reaction. Google has got to respond by either explaining what String did wrong, or fixing the problem in the latest SDK release.

Re: [android-developers] Re: Reflection API:List all classes in a package that extend a specific super class
Thank you for your reply! Very possibly there is another solution. The problem to be solved is that I want to run some test scripts stored as assets to test multiple activities. The test scripts need access to the activity to be tested. This is normally done by subclassing ActivityInstrumentationTestCase2, so my plan was to generate subclass of ActivityInstrumentationTestCase2 for each activity to be tested, and let this class scan the assets directory for related test scripts and run them. Using junit.framework, I would like to define one TestCase per script, or multiple TestCase instances per script. If the suite() method of the ActivityInstrumentationTestCase2 subclass could scan the assets directory, I would not need to scan for classes. Is this possible? How can I scan assets in a static context? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Smooth OpenGL movement and animation tips.
I've not much to add, but at any rate: 1) As has been noted, GC is the enemy. String manipulation, boxing/ unboxing, using most collections other than ArrayList, Collections.sort(), Arrays.sort() - they all create garbage and you simply cannot use them on a per-frame basis. Happily the GC pauses are so noticeable that you'll quickly turn to the (excellent) allocation tracking tools to root out the problem. 2) Everyone doing OpenGL work, and hence working with FloatBuffers, should be aware of http://code.google.com/p/android/issues/detail?id=11078 Ryan On Feb 25, 7:04 am, oldskool73 oldskoo...@gmail.com wrote: It's good of you put some suggestions out there to help others, and I'm not trying to have a dig, but none of those tips have anything to do with opengl(es) specifically.

Make sure you animate/move using a timer to maintain a constant rate of movement regardless of processing speed. So, x = now draw 1st frame y = now movementFactor = y - x; draw 2nd frame repeat That sorts some problems. 2. Stop the GC firing. If you're getting the gc firing message in the logcat whilst movement or animation is taking place your likely to be allocating ram. You can check this in ddms, goto the allocation tracker, hit start tracking then get allocation and you'll see what methods have been allocating ram. 3. Stop allocations even if the GC isn't firing! This helped me a bundle, I was allocating a lot of Strings and once I sorted this out I found the frame rate to fluctuate less. 4. Put the phone in airplane mode when doing performance testing and kill all tasks prior to running your app. 5. (Not tried this one yet) Apparently you're eye is very good at seeing jerks in animations.movement so it's actually better to reduce your frame rate artificially as explained by Mario Zechner below, Average your delta times, it's the only way you can smooth things out. I use a window of 5 frames per second for which i sum up the delta times and divide by the number of frames. An example, 15ms, 15ms, 33ms, 15ms, 15ms will give you an average delta time of 18.6ms for frame 6. The 33ms will also influence the delta time of the next 4 frames after it. To avoid that effect you could use weighted averaging: frame delta times that are newer receive a higher weight (just an example, haven't boughtered using it) Does anyone have any other ideas concerning this topic? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] AdapterView.OnItemSelectedListener.onItemSelected called with out of date position argument!
Hi, I have a strange behavior in a very specific case and wonder if the issue comes from my code or not. I have a TabActivity A with 2 tabs: - Tab 1 content is created as a view with a spinner in it - Tab 2 content is an activity B. I want at some point when Tab2 is selected to switch to Tab 1 and update spinner selection in it. Case 1) Tab 2 is selected, from Activity B context: activityA.updateSpinnerSelection(newposition); activityA.getTabHost().setCurrentTabByTag(tab1tag); later AdapterView.OnItemSelectedListener.onItemSelected is called with my newposition = so this *usually *works fine: Case 2) Tab 2 is selected, from Activity B context, but before doing the same things, if the users for some reason *first open a new acticity C on top of B (like preference screen) and close this activity C*, (so A and B are paused then resumed), then if I later try again the same things: activityA.updateSpinnerSelection(newposition); activityA.getTabHost().setCurrentTabByTag(tab1tag); so far so goog, but later AdapterView.OnItemSelectedListener.onItemSelected is called not with newposition as argument *but with the older position value*. I hope the description is clear. Did I missed something? or could this behavior dues to some bug in Android?

[android-developers] Controlling Android init process / staged boot
Hi, I am trying to achieve something like a controlled or 'staged' boot process, where I can make sure that a specific program or script is executed first in the init process and then the remainnig services are started. I was able to start my own services from the init script (init.rc) in Android, following the guides found at: http://www.androidenea.com/2009/08/init-process-and-initrc.html or with the official documentation found at http://android.git.kernel.org/?p=platform/system/core.git;a=blob;f=init/readme.txt;hb=HEAD There is a trigger called on service-exit-name where 'name' is the name of the service which has to exit before the actions of this trigger are executed. However, this trigger does not seem to work. I started a small shell script as a service and created the trigger accordingly to start all remaining services afterwards. The init process seems to be stuck after the execution of my script and does not continue with the remaining services. Example layout: on boot #default entries # changed from start of default services to class initialize class_start initialize #service section for my own app to be started first before anything else service runfirst /system/bin/logwrapper /sbin/myapp class initialize oneshot on service-exited-runfirst #start remaining services class_start default # further service descriptions, e.g. service zygote ... etc. Any help on that subject is very much appreciated. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: Reflection API:List all classes in a package that extend a specific super class
Don, ActivityInstrumentationTestCase2 has a method, getInstrumentation(), which gives you an Instrumentation object instance that's used in the test. Instrumentation has getContext() which gives you your test package's context object, now you can access its resources (as opposed to resources of the target application - those are under getTargetContext()). http://developer.android.com/reference/android/app/Instrumentation.html#getContext() Now you can call getResources() on your test package's context, and the rest should be easy: - Either call getAssets() to get AssertManager and then list() to get the list of script files; - Define a integer-array's within your test package resources, with references to individual XML entries, one array per test case. Load the array with res.getIntArray(), then call res.getXml() to open individual scripts. I'd do the latter, to separate the scripts for individual tests from one another. Hope this helps. -- Kostya 25.02.2011 12:58, donV ?: Thank you for your reply! Very possibly there is another solution. The problem to be solved is that I want to run some test scripts stored as assets to test multiple activities. The test scripts need access to the activity to be tested. This is normally done by subclassing ActivityInstrumentationTestCase2, so my plan was to generate subclass of ActivityInstrumentationTestCase2 for each activity to be tested, and let this class scan the assets directory for related test scripts and run them. Using junit.framework, I would like to define one TestCase per script, or multiple TestCase instances per script. If the suite() method of the ActivityInstrumentationTestCase2 subclass could scan the assets directory, I would not need to scan for classes. Is this possible? How can I scan assets in a static context? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Smooth OpenGL movement and animation tips.
Yeah perhaps I could of named the topic something else... But these tips/ideas are aimed specifically at game devs who will clearly be using OpenGL ES. Anyway RE 1, that's a very interesting take on it and yeah I definatley think that slowing the physics down if the frame rate drops sounds like a great idea in your case... The point was however though that you should always be using time not processing power as a reference point. Games should have an optimum speed they try to run at which is not dependant on the hardware. RE 4, I think you've missed the point. I mean when checking for smoothness you should use airplane mode and kill everything. You need to know any glitches you see aren't related to what's going on in the background. I didn't mean you should tune your game so it only runs in airplane mode. Thanks for the link to the openGL stuff by the way!

Make sure you animate/move using a timer to maintain a constant rate of movement regardless of processing speed. So, x = now draw 1st frame y = now movementFactor = y - x; draw 2nd frame repeat That sorts some problems. 2. Stop the GC firing. If you're getting the gc firing message in the logcat whilst movement or animation is taking place your likely to be allocating ram. You can check this in ddms, goto the allocation tracker, hit start tracking then get allocation and you'll see what methods have been allocating ram. 3. Stop allocations even if the GC isn't firing! This helped me a bundle, I was allocating a lot of Strings and once I sorted this out I found the frame rate to fluctuate less. 4. Put the phone in airplane mode when doing performance testing and kill all tasks prior to running your app. 5. (Not tried this one yet) Apparently you're eye is very good at seeing jerks in animations.movement so it's actually better to reduce your frame rate artificially as explained by Mario Zechner below, Average your delta times, it's the only way you can smooth things out. I use a window of 5 frames per second for which i sum up the delta times and divide by the number of frames. An example, 15ms, 15ms, 33ms, 15ms, 15ms will give you an average delta time of 18.6ms for frame 6. The 33ms will also influence the delta time of the next 4 frames after it. To avoid that effect you could use weighted averaging: frame delta times that are newer receive a higher weight (just an example, haven't boughtered using it) Does anyone have any other ideas concerning this topic?- Hide quoted text - - Show quoted text - -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: SQLite and Collate UNICODE
Read some other pages maybe ;-) But thanks for the comments. Elsewhere in the Android docs it says the unicode collator is case-insensitive by default. the c source seems to be trying to setup a level 1 collatorbut... and as I said in my original post, the unicode collation *sorts* in a case-insensitive way. it just does not test equality in the same way it sorts. which seems very odd. Maybe I just don't understand unicode collation. On Feb 25, 10:36 pm, DanH danhi...@ieee.org wrote: That page says nothing about UNICODE doing case folding.

Re: [android-developers] Differnce between Page Switcher and Page Flipper
There is no PageSwitcher or PageFlipper class in Android. Hence, you will want to ask your question of whoever wrote those classes, in whatever third party package you are referring to. If you are really referring to ViewSwitcher and ViewFlipper, ViewSwitcher has only two children, while ViewFlipper can have as many as is needed.

[android-developers] Android 2.3.3 on N1 - Slow bitmap blitting?
Hi, I have updated my Nexus One (not rooted) to stock 2.3.3. Everything looks fresh and nice! But my app runs only half as fast as before! It is a fluid simulation ( https://market.android.com/details?id=com.gestaltgeber.hyperspacejellylite). The simulation and rendering is done in native code with the NDK. I pass a bitmap to native code (an Android 2.2 feature) and blitt the final bitmap in Java. It works exactly like the plasma example from the NDK. But my frame rate has dropped from approx. 30FPS to approx. 15FPS after the update. I will probably measure more exactly over the weekend. I think the native code is probably running as fast as before. So the slow down is probably caused by a slower blitt function or the screen composition has become slower. Does someone else see similar problems with Android 2.3? Any slow downs in other apps?

[android-developers] Re: Service Lifecycle
In my particular situation, I was using onCreate() to initialize state variables to their initial values. My expectation was that onCreate() is called just once for the lifetime of my app. Now that I know that Android can destroy my service if needed and cause it to be recreated, that form of initialization won't work for me. That being the case, I moved that logic to onHandleIntent() where it initializes the state variables from persisted storage. Incidentally, onStart() is deprecated and onStartCommand() is not recommended for override according to the docs; it specifically states that you should override onHandleIntent() instead.

[android-developers] EditText behaving weirdly

The dialog is created with a xml layout and using an inflater at runtime. I also populate the edit text field with a value. For some reason, the following happens when the dialog opens. 1st time: The cursor is posistioned after the text in the edit text. The getSelectionStart value is 0. 2nd time: the cursor is correctly at the start. getSelectionStart returns a random value, but never 0. 3rd time: Everything works as it should. Cursor at start and getSelectionStart returns 0. Not sure if this matters, but I build the dialog in the onCreateDialog and set the values of the title and textbox in the onPrepareDialog.

[android-developers] Java code limited to ~24Mb memory and NDK code has no limit?
After writing Java apps for a while and being mindful of the heap memory limit (typically 16Mb or 24Mb), I was surprised to discover recently that NDK apps have no limit on how much memory they can allocate. I have a few queries: 1. Why was the decision made to not enforce the same limitations on NDK code? 2. What are the implications of rewriting apps that use the NDK to allocate, say, double the regular Java heap limit? I've done some experiments and e.g. using 40Mb on a phone with 256Mb RAM and a Java heap limit of 24Mb doesn't seem to cause any noticeable problems. Background apps start getting killed when you use a lot more memory though. 3. Are there any plans to increase the Java heap limit? Seeing as phones are now getting =512Mb RAM, giving less than 10% of this to the foreground app seems an odd limitation. I've noticed apps on the market that say they require 256Mb RAM to run (!) so other developers are definitely taking advantage of the NDK in this way. I much prefer coding in Java but the memory limit makes certain apps very tough to write so sticking to Java makes it hard to compete with developers that use the NDK. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Just as I suspected there is a bug in Honeycomb that allows me to work
around not having a setHasAlpha function.
Using the new inMutable option in BitmapFactory.Options I can decode a
dummy JPG and because it is a JPG the opaque hint is set. Now whatever
set function you call on the bitmap, the opaque flag is never cleared
and so it optimizes the drawing. It is rather silly though that I have
to do it this way.
I also wonder how the Android team is going to fix the actual bug in
Honeycomb. There are four ways as I see it:
1) When inMutable is set it always clears the opaque hint. This would
be dumb because it assumes the worst case scenario.
2) For every set function check if it has transparent values so it can
clear the opaque flag. Lots of work and not very fast
3) Add a XRGB_ Config. Not sure what kind of work is involved
here.
4) Make the setHasAlpha public. This would be the easiest
solution :-)

Hi Romain
Looking further into the Android source code when you create a 32-bit
color bitmap the system always assumes you have alpha and there is no
way to turn it off. Only when you load a JPEG or something does the
system set the flag to ignore it.
That is an unnecessary performance penalty that can easily be avoided.
For Honeycomb could you please make the setHasAlpha public or provide
an XRGB_ config. For the upcoming tablets we are going to draw
even more and bigger bitmaps.

not present in ADT's android.jar so you cannot compile against it. We
also
might rename or remove such APIs at any point in the future.

Something like Bitmap.createBitmap( 512, 512,

Or does the system somehow detect that the bitmap is opaque?

[android-developers] MediaPlayer issues in certain devices
Hello all: I've searched around and have not been able to find an answer to this problem: My application plays mp3 files and mp4 files in a variety of ways. The first way is that I have an mp3 stream that I'm streaming through a MediaPlayer object...the second way is that I'm navigating to either mp3 or mobile mp4 files on a website and using the device's native media player and/or downloaded 3rd party media players to play some podcasts. My issues come from the fact that I've tested my app on two different devices...(a Droid2 non-global Android 2.2 system version 2.3.20.a955, and an HTC EVO with Android 2.2). The issues I'm having is that the streaming mp3 audio plays totally fine on the HTC device, but will not play at all on the Droid2, and then the opposite issue is happening with the podcast audio...it will play fine on the Droid2 using both Winamp and doubletwist...but the HTC device will not open and play these files even in the native music player. The HTC user says that a browser begins to open and then closes and no audio ever plays...he didn't say anything about an error message either. The Droid2 user gets no error message for the streams...they simply don't play...he also says he's not been able to get streaming audio from other apps as well so he figures it's his device. However with the podcasts, it will open a browser and then ask him which application he wants to use to play the media...then it opens just fine and plays. Has anyone else experienced this or knows of something I might be able to do in my app to fix this? Is this strictly a device issue? Both the streams and the podcast audio and video play perfectly fine in the Emulator (not that that is any indicator that everything is going to work on a device) and I'm getting no error messages or anything in the logcat. I'm working on getting a third device to test on to see what, if any issues occur. The rest of the app seems to work totally fine on both devices.

[android-developers] Do existing scheduled items on the AlarmManager get cancelled after an application update from the Marketplace?
Hi all. I was wondering what would happen in the following scenario: Your application schedules a service or any type of pending event on the AlarmManager. Let's say it repeats every 24 hours at noon. If an application update is available, and the user updates the application at 10 AM through the Marketplace app, does that update remove all scheduled events from the AlarmManager? Or will the service still start at noon? I understand that there could be complications if the pending events aren't removed: the application update could have completely removed the service that would have been started. But in that case, the AlarmManager would just catch an exception when it tries to start the service and ignore it. On the other hand, if the AlarmManager DOES remove all the scheduled events, how is your application supposed to restart the services? 1. You can't tell on the application startup whether or not your previous services have been cancelled, because there is no way for your application to query AlarmManager to see if your services are still scheduled or not. 2. You can't blindly start your service at app startup, because you don't want a service that is supposed to run every 24 hours to run 5 times a day if the user starts your app 5 times that day. 3. Even if you persist a flag to disk indicating that your service is running, your application doesn't receive an event that the service was stopped (that I know of), so you can't turn that flag off if the service is cancelled during an application update. Does anyone have any advice on how to reliably keep a service scheduled consistently after an application update?

Re: [android-developers] Java code limited to ~24Mb memory and NDK code has no limit?
On Fri, Feb 25, 2011 at 8:31 AM, spaceraiders spaceraid...@gmail.comwrote: 1. Why was the decision made to not enforce the same limitations on NDK code? It is much harder to enforce on native code. 2. What are the implications of rewriting apps that use the NDK to allocate, say, double the regular Java heap limit? I've done some experiments and e.g. using 40Mb on a phone with 256Mb RAM and a Java heap limit of 24Mb doesn't seem to cause any noticeable problems. Background apps start getting killed when you use a lot more memory though. If you aren't careful in native code, your app will simply be silently killed on you. 3. Are there any plans to increase the Java heap limit? Seeing as phones are now getting =512Mb RAM, giving less than 10% of this to the foreground app seems an odd limitation. The heap size is larger in HC. I've noticed apps on the market that say they require 256Mb RAM to run (!) so other developers are definitely taking advantage of the NDK in this way. I much prefer coding in Java but the memory limit makes certain apps very tough to write so sticking to Java makes it hard to compete with developers that use the NDK. It's up to you whether you want to stay within the limit or risk issues like your app suddenly disappearing on the user. You can use the onLowMemory() callback to help you determine when you are starting to allocate too much memory. The browser uses this for example to know when it really needs to flush its caches. HOWEVER, you should NOT be relying on that as the only way to control your allocations, since it happens when the device is really getting low on memory to the point of not being able to keep any background processes running, so things like app switching are already being impacted by your memory use. -- Dianne Hackborn Android framework engineer hack...@android.com Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.

Re: [android-developers] Out of memory - despite being way under 16mb
Memory fragmentation does not cause this; the Dalvik heap limit is enforced based on the actual active allocations. Note that bitmaps are NOT include in the Dalvik heap based on what ddms reports, but they are included in the heap limit, so most likely you have a lot of bitmap data. (In HC this is changed and bitmap data is now allocated directly on the Dalvik heap.) On Thu, Feb 24, 2011 at 12:42 PM, Sheado chad...@gmail.com wrote: Hello. I tried posting this earlier, but it didn't seem to stick (so sorry if it double posts). My app occasionally runs out of memory when loading bitmaps.

Re: [android-developers] Problems with Calendar Provider queries
The calendar provider has and will change, often significantly, between platform releases. And I would be willing to bet that some device manufacturers have changed it for their own use.

[android-developers] NFC question: card emulation is not supported in the Android SDK yet, right?
I'm no NFC guru, but from what I can tell of the docs and the samples, there's no way to do card emulation on an Android device at this time, using the SDK. Is that correct? I see the published classes/methods for reading/writing tags, and for the Ndef push using P2P and the mysterious com.android.npp package (anyone know where there's more information on that?). But that doesn't get me to turning the Android device into whatever tag I want it to be read as by some other NFC reader, at least I'm pretty sure it doesn't. Unless the NFC sensor reads and writes my device's tag if there happens to be one on the device. Is that how it's supposed to work? If that last part is true, is there some sort of convention on how I recognize my tag as compared to any other tag I come into contactless with? I saw posts describing how to do this from the NDK level but I'm asking about from the SDK level. I also saw source code with unpublished methods for card emulation, which leads me to believe that it's just not possible, yet.
