Android dalvik garbage collection may crash?

We're working on a project for Android jelly bean. Our platform is arm-based, and the kernel version is 3.1.10. In our development process, we found that there is very low probability that the application crash happened in dalvik. Based on the following backtrace log, the crash appeared during garbage collection function. After using addr2line to analyze the pc address, we found the obj->clazz became a violate address when the issue has happened.
The code flow is:
(dvmHeapScanMarkedObjects -> processMarkStack-> scanObject->(IS_CLASS_FLAG_SET(obj->clazz,CLASS_ISARRAY)))
Now we are stuck here and can’t find a way to solve it. So we need more suggestion and help.
Does anyone know this issue or how to keep checking on it?
The backtrace log as below:

Ah it took me quite a long time to analyse the situation for me with a similar issue. Hope my analysis help you .
With my issue , the problem is because of Memory reordering by compiler . In dalvik several threads share common memory ASHMEM . This ASHMEM might have been corrupted because of memory re-ordering by compiler for optimisation .
To avoid memory reordering at particular point execute memory barrier (AKA membar) .Check this link for executing membar
Just put a memory barrier ANDROID_MEMBAR_BARRIER() before object allocation and object freeing in Garbage-collecting memory allocator(like dalvik/vm/alloc/alloc.cpp) and in class.cpp , array.cpp and proxy.cpp in dalvik directory of android source code . This should solve the issue.
For more infomation on Memory barrier pls check following links
memory barrier
example
white paper on Hardware View of Memory Barriers

Do you mean put ANDROID_MEMBAR_FULL() behind all dvmMalloc just like code in the following?
And Where is the memory free function in the garbage collection flow? thank you
static bool createInitialClasses() {
/*
* Initialize the class Class. This has to be done specially, particularly
* because it is an instance of itself.
*/
ClassObject* clazz = (ClassObject*)
dvmMalloc(classObjectSize(CLASS_SFIELD_SLOTS), ALLOC_NON_MOVING);
ANDROID_MEMBAR_FULL();

How to play Live Streaming video in Android

In my project I have a requirement to play live streaming video. I have seen many comments that "live streaming is supported only from 3.0" so that I have to use emulator 3.0. But it does not play. Can anybody help for me.. This is my code:
String SrcPath="http://akamedia2.lsops.net/live/smil:cnbc_en.smil/playlist.m3u8";
myVideoView = new VideoView(this);
myVideoView.setVideoURI(Uri.parse(SrcPath));
setContentView(myVideoView);
myVideoView.setMediaController(new MediaController(this));
myVideoView.requestFocus();
myVideoView.setOnErrorListener(new OnErrorListener() {
public boolean onError(MediaPlayer mp, int what, int extra) {
// TODO Auto-generated method stub
return false;
}
});
myVideoView.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
// TODO Auto-generated method stub
myVideoView.start();
}
});
The following logcat for this:

According to some threads, you should use httplive:// scheme for version 2.3 and 3.0 and the http:// scheme for 3.0+: How to play m3u8 on Android?
It worked on my 2.3 device but I'm not sure if it wold work on an emulator. Moreover, I made it work using the m3u8 test URI ( http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8 ) of apple. I can't still make it work using the my own URI.

Errno = 13 and how to debug this more efficiently?

I'm making an application and when i go from menu to an other activity that display image using the e3roid framework, i allways get this (logcat):
D/PhoneWindow( 1562): DebugMonitor class=com.recisio.kfandroid.gui.tab.KFFeaturedTab focus=false
E/copybit ( 1562): Error opening frame buffer errno=13 (Permission denied)
D/PhoneWindow( 1562): DebugMonitor class=com.recisio.kfandroid.gui.player.KFPlayer focus=true
I'm questionning myself about where does the error come?
Is there a way to know exactly where it happens?
May i have to ignore this?
Apparently, copybit is just an abstraction for a basic 2D blitter with support for rotation, scaling and color/pixelformat conversions.
But where it's strange it's that all the images loaded appears well on my screen.
Ok: I tried to change the way i was encoding the bmp I print like this:
return Bitmap.createBitmap(bitmap_width, bitmap_height, Bitmap.Config.RGB_565);
but it doesn't solve the problem.
By printing several display infos everywhere in my code i realised that the error happens while loading the e3roid engine.
I'm going to look at the sources while waiting for more answers.
After some tests with printing a bmp i create before (valid), I get this

What is this?

Hmm..I guess your device supports ARGB_8888 because all the images
loaded well on your screen. OpenGL sometimes shows strange errors when
the device encounters low memory situations.

I had the same error some times ago, it was due to a lack of memory. In the emulator logcat and not on my phone (wildfire) it was saying: OutOfMemoryException.
Make sure you use the recycle() nethod to clear bitmap from the memory.

This can happen if you are using a not supported texture format. Try using a RGB565. Here you can find some info about the issue: http://code.google.com/p/processing/issues/detail?id=391

Android & JNI_OnLoad lead to a crash on device

I am pretty new to working with JNI on Android, and I've been writing an app that requires the implementation of JNI_OnLoad.. I've perused the internet for help, and it seems like a lot of different documents conflict in how this function should be implemented. Nevertheless, I went with a method that seemed to work on my emulator but not on my device.
LogCat produces the following:

The following is my JNI_OnLoad implementation...
JNIEXPORT jint JNICALL JNI_OnLoad(JavaVM *vm, void *reserved)
{
LOGI("Executing JNI_OnLoad");
JNIEnv *env;
jint onLoad_err = -1;
jclass k;
static const char* const strClassName="com/example/helloandroid/HelloAndroid";
cached_jvm = vm;
// Checks JNI version
if((*vm)->GetEnv(vm, (void**) &env, JNI_VERSION_1_4) != JNI_OK){
LOGE("JNI Check failure");
return onLoad_err;
}
// Checks if environment is null
if (env == NULL) {
LOGE("Env is NULL");
return onLoad_err;
}
k = (*env)->FindClass(env, strClassName);
if(k == NULL){
LOGE("Find Class returns NULL");
return onLoad_err;
}
if ((*env)->RegisterNatives(env, k, methods, sizeof(methods)/sizeof(methods[0])) != JNI_OK){
LOGE("Method registration failure");
return onLoad_err;
}
LOGI("Successfully executed JNI_onLoad");
return JNI_VERSION_1_4;
}
Is there something specific about native code that makes it act differently on an emulator than on an actual device? Or do I need to do more in JNI_OnLoad?
Thanks in advance!

There's nothing you should need to do to run on a device that isn't already done on the emulator.
I notice from your log that your device is an x86 type device. The emulator is an ARM processor... are you trying to run ARM code or x86 code on your device?
