[android-developers] Re: Memory leak in BitmapFactory/Gallery?
Thank you very much, fadden! It is much appreciated. For now I appear to have fixed not only my run-to-run memory leaks but also the frequent multi-run crashes by ensuring that my threads finish. From reading this group I had just been looking in the wrong direction when hunting for context leaks in relation to bitmaps and the camera, because in hindsight I could with every run see the number of threads grow in the thread view of DDMS (just not visible by default). When compiling hprofConv.c I noticed that stdint.h is not included with Visual Studio C++ products (http://en.wikipedia.org/wiki/ Stdint.h), so I fetched the portable stdint.h pstdint.h from the web (http://www.azillionmonkeys.com/qed/pstdint.h). Next I found that I had to redefine DBUG for lack of support for variable length argument lists in my (old) C preprocessor, and I had to apply a few explicit casts to HprofBasicType to satisfy the VC compiler. Of course I fully understand that HprofConv was not yet developed for maximum portability but for in-house use. I will experiment with your HprofConv utility later. Thanks!

[android-developers] Re: local service getting killed
Yes, i ran into the very same problem. From what I understood with documentation and logcat traces, I may be wrong for some details but here's the general idea: My background service (I use startService/stopService to handle an XMPP connection and notifying the user of events when no activity is running/binding to it) can be killed when the phone is on low memory (e.g. under 16 MB on my G1, this the value of the threshold, see the ActivityManager class, very interesting monitoring functions...). Android first calls onLowMemory() on Activity, Service and Application classes to give applications a chance to free some memory. After that, android kills the most memory consumer services until the phone's free memory is greater than the threshold, in the logcat you will see tons of traces about all that process. Services that are killed for memory reasons are scheduled for a restart (you will also see a logcat trace for that). On Jan 30, 9:09 pm, brs bernhard.r.su...@gmail.com wrote: I have an app loosely based on the LocalService example from the SDK with a controller activity and a long-running, stateful service which is doing stuff on a periodic handler. The service is also a bit of a memory hog. It seems that the service is sometimes killed by the activity-manager and immediately restarted. I don't see any stack trace, so I assume it is not the application crashing but the system doing that, presumably to claim resources. Is that what is going on here? Is there a way to tell the system that this process is kind of important, even though it has no foreground activity and should only be killed as a last resort?

[android-developers] Re: Memory leak in BitmapFactory/Gallery?
There is bug in BitmapFactory memory allocation, there are tons of
threads in this mailing list dealing with that.
To sum up:
At a normal time when you create an object, the heap size is
automatically grown if not sufficient enough (there is an absolute
limit of 16MB per process though, you will crash if you exceed this).
But the bitmap factory allocates memory in a non Java way, it uses
native code to do that, and the heap growing process fails if not
enough memory in this case!
So even if you are far under the 16MB limit, if you are unlucky enough
to have the heap grown up for your image to be allocated, you will
have an OutOfMemoryError
Some guys claim that this crash can be avoided by catching this error
(catching an error instead of an exception is quite unusual by the
way)...

Hey gym,
1) You don't have to go that far. No need to close or reset anything,
simply run the app from within the emulator (obviously, you need to
update it via adb install -r or something if you changed it). It will
show up in the process list in the DDMS, but you'll see that it
doesn't have that cute bug next to it. You can still add the heap
watch to it, this will not affect anything. And you can always attach
the debugger later if you need to debug something -- if you have the
heap watch on too, you might be able to see a change in behavior as
soon as you attach it. In my test app that repeatedly called
BitmapFactory.decodeFile and/or threw an exception, I noticed an
immediate continual increase in memory usage until it OOMed.
2) You won't necessarily see any garbage collection until the VM
decides to collect. That's okay. It doesn't matter if your app takes
up 15MB without ever collecting garbage. But as soon as you do an
allocation that exceeds the amount of available RAM, the gc should
kick in and take out the trash. Basically, it's all good as long as
you don't OOM. If you OOM, something went wrong.
Please note the very beginning of this thread - there is a known
problem in the Gallery class, it never recycles its views. However, I
have an app that uses two Galleries, both of them using
BitmapFactory.decodeFile(). I've run it on my device, sometimes with
1000 entries in the Gallery and scrolling like crazy, and I've never
OOMed. If I have the debugger attached, I OOM pretty quickly.
3) Interesting. SHOULDN'T happen, the VM should automatically gc as
soon as you're running out of memory.
Are you doing anything funky with your Bitmap/Drawable objects? How do
you manage them?

I have noted the following discrepancies compared to the descriptions
here, using a similar, simple application which uses Gallery, and
BitmapFactory:
1) EboMike, How exactly do I run the application without a debugger
attached? I assume that closing Eclipse entirely, and launching a
new emulator from a DOS prompt (without Eclispe running) would be the
equivalent of not having a debugger attached.
When I do this, I get the same memory leak problem as I always did...
2) When I have the DDMS attached and running, the heap size doesn't
show any garbage collection (see below) going on for my gallery
application (unless I click on Cause GC)...
3) If I call System.GC() intermittently directly in my application
(calling this method alone, and not as part of a {gc() /
runFinalization() / gc()} sequence), this prevents OOM, and then I can
see the GC altering the heap size (in DDMS).

I've tried it with no de-bugger, on the emulator, and on actual G1

Bitmap allocations are done outside of the virtual heap, but are
counted against it. This was done somewhat late in the game and not
all of the tools will include the bitmap heap allocation numbers in
with the actual virtual heap allocations. If you're getting an OOM
you should see it bumping up against the 16MB limit in the logs.
FWIW, the only thing worse than explicit calls to System.gc() is
following those with explicit calls to System.runFinalization(), which

[android-developers] Re: WiFi in Emulator
there is a single ethernet port in the emulated system. It is connected to an internal firewall/router within the emulator code that emulates all connectivity through standard BSD sockets. Which connection is used depends entirely on your host machine setup, but wifi or no wifi doesn't have any importance to the emulated system. second, wifi is not supported in the emulator because it is darn impossible to properly emulate that at the low-level protocol layer, and doing any kind of bridging at a higher layer requires invasive modifications to the system that would be no use to a normal device (except that they introduce much more complexity and potential for bugs / security issues). in the future, we're likely to create emulator-specific system images that can have all kinds of hacks in them to support whatever weird feature, if possible. Right now, we're essentially using the same system images for devices and the emulator, which makes this kind of modifications unreasonable. (yes, it also means that current device images already have a few emulator-specific hacks in them, and we want to get rid of them).

[android-developers] What's the trick to do a (forward) geocode?
IIUC, doing a forward geocode (looking up an address from a name) is pretty
straightforward, you do this:
private void findLocation() {
ListAddress locations = null;
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
try {
locations =
geocoder.getFromLocationName(mName.getText().toString(), 5);
} catch (IOException e) {}
}
If I put in The White House or AP Washington NJ, I get nothing back,
but the application Locale shows both. If I put in The Empire State
Building, I do get an address back.
What's the trick?

[android-developers] Re: gapless playback
Yes, two reasons actually. One, because the Ogg spec allows for specifying the exact number of samples in the stream. MP3 does not have an official way to specify the number of samples (there are unofficial ways). Two, because the Ogg player has a native loop capability that allows us to seamlessly loop at the exact sample boundary. OpenCore does not support seamless loops, we have to explicitly seek to the beginning of the file in loop mode. Thus any streams that are rendered by OpenCore (i.e. everything but Ogg and MIDI) will have gaps.

[android-developers] Re: Audio in the emulator...
Hello,
I have been searching for some time and I can't find a detailled
tutorial on how to easily record and then read audio on the emulator
under eclipse. I have found these steps:
- You have to install a virtual sd card with mksdcard.exe 1024M
sdimg.iso
-then run the emulator : emulator.exe -sdcard
sdimg.iso//where sdimg.iso it is the path to
the sdcard
-then run adb.exe : adb push local_file sdcard/remote_file
-then you should put : uses-permission
android:name=android.permission.RECORD_AUDIO/uses-permission in
the androidmanifest.xml
-then there is some code to implement which should look like :
private void startRecord() {
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC); //ok so
I say audio source is the microphone, is it windows/linux microphone
on the emulator?
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(/sdcard/test.3gpp);
recorder.prepare();
recorder.start();
}
-then you should stop with : recorder.stop(); // at some point (I have
no idea when and where to decide to stop but I haven't searched yet)
-then you should play it.
I have also heard about :
http://code.google.com/intl/fr/android/reference/emulator.html#sdcard
in this page of the manual (~1/4 of the total scroll), there are some
informations about Emulator Startup Options, one of them is about
Media -audio backend
I couldn't find much about that backend thing, google didn't said much
about it. I still don't know if it's important to the audio recording
process.
The fact is all these steps are pretty blurry to me, and I believe I
am not the only android newbie trying to record some sound :)
Anyone knows where we can find a complete tutorial for dummies
teaching this feature?
Any help is of course greatly appreciated
Thanks.

[android-developers] How to get the position of the click point.
Hi, I'm working on a simple application, I need the application to give different response when the user click different position of the screen. But it seems I can't get the position in the OnClickLisenter, I tried OnTouchListener, but it's not as well as I expected. Can you give me some help on this? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Android Development Forum
Hey Androiders, Buzz is happening around Android already. Off course there are developer groups, where we can find out answers to questions. But we (www.androidcompetencycenter.com/) have decided to provide support to all developers through newly launched forums. Do check out the blog, discuss, bounce each other off with questions. Looking forward for great discussions on the blog. Best Regards, Sushrut PS - I hope this discussion was not spammy, I thought it was relevant enough. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: MediaRecorder - No value other than 0 returned from getMaxAmplitude
are you testing it on the emulator or on the G1 device? I'm not sure about it but I've read around some forums that you need a virtual sd card to record audio on the emulator. (with the mksdcard.exe in the tools provided with the sdk) Some other sources also say it isn't possible to record audio on the emulator yet. Check if you can read/hear what you have recorded since you are using a sdcard, maybe the sdcard is too small. Why would you use a thread to return the max amplitude? I am myself looking forward to record audio on the emulator and constantly find contradictory informations about whether it's possible or not. the manual says it's not. Any insight about that is appreciated in addition to the upper problem. thanks On 31 jan, 15:12, ph...@grantmidwinter.com ph...@grantmidwinter.com wrote: I've got a media recorder, prepared and started in the following way: mRecorder = new MediaRecorder(); mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); mRecorder.setOutputFormat (MediaRecorder.OutputFormat.THREE_GPP); mRecorder.setAudioEncoder (MediaRecorder.AudioEncoder.AMR_NB); mRecorder.setOutputFile(/sdcard/test.3gpp); mRecorder.prepare(); mRecorder.start(); I'm then using a thread to return the mRecorder.getMaxAmplitude int, but it never returns as anything but 0.

[android-developers] Re: Memory leak in BitmapFactory/Gallery?
Guillaume, that kind of sounds like you're running with a debugger
attached... see somewhere in the middle of this long thread, it is
known that the system will leak memory when you run with a debugger
attached - mostly when exceptions are involved, and
BitmapFactory.decodeFile() always throws (and catches) an exception.
Do you get the same results when you run without a debugger? All my
memory woes have been fixed when I stopped using a debugger except
when necessary.
-Mike
On Jan 31, 8:14 am, Guillaume Perrot guillaume.p...@gmail.com wrote:
There is bug in BitmapFactory memory allocation, there are tons of
threads in this mailing list dealing with that.
To sum up:
At a normal time when you create an object, the heap size is
automatically grown if not sufficient enough (there is an absolute
limit of 16MB per process though, you will crash if you exceed this).
But the bitmap factory allocates memory in a non Java way, it uses
native code to do that, and the heap growing process fails if not
enough memory in this case!
So even if you are far under the 16MB limit, if you are unlucky enough
to have the heap grown up for your image to be allocated, you will
have an OutOfMemoryError
Some guys claim that this crash can be avoided by catching this error
(catching an error instead of an exception is quite unusual by the
way)...
On Jan 18, 12:31 am, EboMike ebom...@gmail.com wrote:
Hey gym,
1) You don't have to go that far. No need to close or reset anything,
simply run the app from within the emulator (obviously, you need to
update it via adb install -r or something if you changed it). It will
show up in the process list in the DDMS, but you'll see that it
doesn't have that cute bug next to it. You can still add the heap
watch to it, this will not affect anything. And you can always attach
the debugger later if you need to debug something -- if you have the
heap watch on too, you might be able to see a change in behavior as
soon as you attach it. In my test app that repeatedly called
BitmapFactory.decodeFile and/or threw an exception, I noticed an
immediate continual increase in memory usage until it OOMed.
2) You won't necessarily see any garbage collection until the VM
decides to collect. That's okay. It doesn't matter if your app takes
up 15MB without ever collecting garbage. But as soon as you do an
allocation that exceeds the amount of available RAM, the gc should
kick in and take out the trash. Basically, it's all good as long as
you don't OOM. If you OOM, something went wrong.
Please note the very beginning of this thread - there is a known
problem in the Gallery class, it never recycles its views. However, I
have an app that uses two Galleries, both of them using
BitmapFactory.decodeFile(). I've run it on my device, sometimes with
1000 entries in the Gallery and scrolling like crazy, and I've never
OOMed. If I have the debugger attached, I OOM pretty quickly.
3) Interesting. SHOULDN'T happen, the VM should automatically gc as
soon as you're running out of memory.
Are you doing anything funky with your Bitmap/Drawable objects? How do
you manage them?
On Jan 17, 9:03 am, gymshoe gyms...@bresnan.net wrote:
I have noted the following discrepancies compared to the descriptions
here, using a similar, simple application which uses Gallery, and
BitmapFactory:
1) EboMike, How exactly do I run the application without a debugger
attached? I assume that closing Eclipse entirely, and launching a
new emulator from a DOS prompt (without Eclispe running) would be the
equivalent of not having a debugger attached.
When I do this, I get the same memory leak problem as I always did...
2) When I have the DDMS attached and running, the heap size doesn't
show any garbage collection (see below) going on for my gallery
application (unless I click on Cause GC)...
3) If I call System.GC() intermittently directly in my application
(calling this method alone, and not as part of a {gc() /
runFinalization() / gc()} sequence), this prevents OOM, and then I can
see the GC altering the heap size (in DDMS).

[android-developers] Re: How good to use intents with an application to communcate and modularise it
Hi Firedger, Thank you bringin clarity by way of internal and external. The one I am refering here is for internal usage. The application I am refering here has Main menu list, which has Settings and About and Help as menu items. On user choosing Settings it would show submenu Login Register Check Updates On About and Help it would display a Rich Text with Hyperliks to talk about vendor of the application and how to use the application. In such impl. is it enough to have one main activity and work on a model to change the view or Do we need to go for One Activity for Main Menu, One each for Settings, Help and About. In one each approach we have to associate a respective view with each of them and go for intent way to bring them to to life. In the contex of one each activity approach, we the following advantages - Go with just one activity for the enitre application, hence no need to think of managing many activities life cycle - AndroidManifest would have only one configuration - Switch the view by way of creating views as it demands and use them - if each view needs a context to create it self properly, pass the paratmers to the constructor of the view, this would also enhance compile checks and enable maintnace as opposed to intent key value pair approach. Closure comparision to J2ME is Canvas which has lifecycle, however many frameworks recommend one instance of canvas only.. We really appricate your inputs on this.

It will tell you which audio backends are available on your system.
You didn't specify what OS you are using.
I think there was also some sample code in the SDK at one point. Maybe
one of the developer advocates can point you to it. Another option is
to look for the source for the Sound Recorder application on

recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(/sdcard/test.3gpp);
recorder.prepare();
recorder.start();
}
-then you should stop with : recorder.stop(); // at some point (I have
no idea when and where to decide to stop but I haven't searched yet)
-then you should play it.
I have also heard about
:http://code.google.com/intl/fr/android/reference/emulator.html#sdcard
in this page of the manual (~1/4 of the total scroll), there are some
informations about Emulator Startup Options, one of them is about

I couldn't find much about that backend thing, google didn't said much
about it. I still don't know if it's important to the audio recording

I have a strange problem where, if the screen is rotated while a
dialog is displayed, an exception gets thrown every time. It happens
_only_ during this single dialog, and the exception is thrown outside
of the app (there's no trace information that touches any of my
code). It happens in both the emulator and the G1.
I'm wondering if anybody has any suggestions about how I might analyze
this problem, or what might be the cause. The stack trace, for what
it is worth, follows. Is this something I can work around, or is it
an Android bug?
Thanks!

I use Thread.stop() but it is not working..Please help.. Killing one thread from another is dangerous, because you don't know what resources are being held by the target thread. The Thread methods for doing this are deprecated, and have not been implemented in Dalvik. The thread should check a variable periodically to see if it should continue running. In many situations you'll want to declare the variable volatile. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Sending Intent to specific Activity
Hi Lutz, When we talk of sending intents from Activity1 to Activity2 , Activity2 should have the intent filter with the intent with which it wants to be invoked. After getting invoked from activity1 , activity2 can further invoke another activity with intent data it wants. You can also use broacastreceivers to get such kind of functonality. Note: Receivers are invoked only by a broadcast call! -Rishi Kaura On Jan 9, 9:56 pm, Lutz Schönemann lutz.schoenem...@sit.fraunhofer.de wrote: Hi, I want to create a activity that receivesintentsmodify these and send them to an other activity that is also registerd to receive this kind ofintents.

[android-developers] Re: INSTALL_FAILED_UPDATE_INCOMPATIBLE
I just figured out how to fix this, but it requires root access. Pull /data/system/packages.xml Find the entry for your package and comment it out. shell back in and chmod packages.xml to be world-writeable Push packages.xml back into the phone. Restart the phone. You can then install the app with the different signature. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: android audio
In SDK 1.0, you can only record to a file using the AMR-NB codec, which is bandwidth limited to 4KHz, and the encoding process itself is pretty lossy. If you want to experiment with this on a G1, go to Messaging, create a new message, click menu and select Attach, and select Record Audio. This will take you to the Sound Recorder activity where you can record and playback audio to get an idea of the audio quality. A future release of the SDK will enable getting at the raw audio samples. On Jan 31, 8:34 pm, solid young...@gmail.com wrote: I am trying to discover the frequeny of recored audio.
