JNI crashlog: source file line determination with stacktrace output

Crashes & ANR section of google play developer console provides this kind of feedback when native code crashes on user's device:
*** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***
Build fingerprint: '...'
Revision: '...'
ABI: 'arm'
pid: ...., tid: ...., name: .... >>> com.package <<<
signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x0
<registers>
backtrace:
#00 pc 003ba9be /data/app/com.package/lib/arm/libx.so (sl_setVolumeSound(unsigned int, float)+105)
#01 pc 003b9db7 /data/app/com.package/lib/arm/libx.so (Audio::setVolumeSound(unsigned int, float)+106)
so far, so good. But how could one determine a source code line out of bytecode offset(?), such as +105 for the sl_setVolumeSound function in the sample output above?
I would especially appreciate a solution which would work completely in macosx command line, with no IDEs engaged.

ndk-stack is specially suited for this purpose. Note, that to get it working you need a non-stripped versions of your native libraries. More details here.

Android M Preview 3 emulator Native Browser crash

I have created an Android emulator with OS(6.0) and when the emulator starts i launch directly the "Browser" app and get a crash.
Here are some logs :
W/System(1617): ClassLoader referenced unknown path: /system/app/webview/lib/arm

Abort message: '[FATAL:gl_surface_android.cc(58)] Check failed: kGLImplementationNone != GetGLImplementation() (0 vs. 0)
does anyone know something about that?
Please find the tombstone file that contains the full crash log :
Tombstone01

Resolved by checking "Use GPU Host" when creating the emulator.

How to use CoreData in Apportable?

I trying the full version of apportable and I have a problem with the CoreData:
I have the correct features at configuration.json:
"FEATURES": ["opengles2","landscape","prefer_external_storage","write_external_storage","write_settings"],
Setting the storageURL where I want to store the DB:
#ifdef ANDROID
//tried many different locations but not luck, I think there is the problem
NSURL *storeURL = [NSURL URLWithString:#"/data/data/com.bluepiggames.zombieSlice/files/Documents/ZS_SuperDatabase.db"];
#else
NSURL *storeURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:#"ZS_SuperDatabase"];
#endif
Creating the persistenceCoordinatore:
NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:
[NSNumber numberWithBool:YES],
NSMigratePersistentStoresAutomaticallyOption,
[NSNumber numberWithBool:YES],
NSInferMappingModelAutomaticallyOption, nil];
_persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc]
initWithManagedObjectModel: [self managedObjectModel]];
Finally, these is the place where the app crash:
if (![_persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:options error:&error]) {
NSLog(#"Unresolved error %#, %#", error, [error userInfo]);
//abort();
And no error prompt in the debugger, only a crash like these.

I/DEBUG ( 8708): r0 63c40b68 r1 6412b13c r2 6412b13c r3 00000000
(EDIT) To solve this crash we must set the before:
NSError *error = nil. //!!!!!
if (![_persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:options error:&error])
Now the problem is in a different place:
// Returns the managed object model for the application.
// If the model doesn't already exist, it is created from the application's model.
- (NSManagedObjectModel *)managedObjectModel
{
if (_managedObjectModel != nil) {
return _managedObjectModel;
}
NSURL *modelURL = [[NSBundle mainBundle] URLForResource:#"ZSDataModel" withExtension:#"momd"];
NSLog(#"Test managedModel found %#",modelURL);
_managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL];
return _managedObjectModel;
}
And the error is because the DataModel compiled not found. Anybody knows how to put the compiled DataModel "DataModel.momod" inside a apportable project?
Thanks

sorry for such a late response, but i didn't want to let the question go unanswered. right now momd files aren't automatically added as assets. unfortunately, there's a manual step you'll need to do every time you update the xcdatamodeld.
navigate to your simulator's Applications directory (e.g. ~/Library/Application\ Support/iPhone\ Simulator/6.1/Applications/<randomString>/<YourApp>.app/)
navigate into the momd directory
run the following in terminal: plutil -convert xml1 <ModelName>.mom -o <pathNearYourApprojFolder>/<ModelName>.mom
in your configuration.json in the add_params dictionary, then in the assets array, add the path <pathRelativeToApprojFolder>/<ModelName>.mom of the file you converted with plutil

Did someone give a try the Http Live Streaming in Android V3.0?

As you should know, Google annonced that Apple Http Live Streaming is now supported in the SDK V3.0 via the mediaPlayer Framework.
So I wrote some lines to test this. I started with a "3gp" movie that is correclty displayed on the emulator (a tablet). When I feed the source with a working m3u8 URL nothing is displayed and the debugger reports an error
Can someone lead me from darkness to light ???
I guess it has something to do with codec but...
Many thanks for any clue.
