I'm using AndEngine with the PhysicsBox2DExtension to make a game. My game keeps crashing and I get this in the unfiltered LogCat:

Can anyone explain to me what's going on and how I might find what exactly is causing the crash?
There are two places in my code where it crashes, but it's fairly random when it does. After executing this method:
private void destroyFiller(){ //Deletes filler
if(filler[fillerNum].active){
Log.e("destroyFiller","Destroying filler");
filler[fillerNum].active=false;
filler[fillerNum].body.setActive(false);
scene.detachChild(filler[fillerNum].sprite);
fillerCount--;
fillersLeftText.setText("Balls left: "+Integer.toString(fillerCount));
if(fillerCount==0)
gameOver();
Log.e("destroyFiller","Destroyed");
}
}
And after executing the indicated line in this method:
private void levelComplete(){
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(TestGFX5Activity.this, "Level Complete", Toast.LENGTH_SHORT).show();
}
});
Log.e("Level Complete","Going to reset values");
//Reset values
level++;
destroyerNum++;
fillerCount = (originalNumberOfFillers + level - 1);
areaFilled=0;
fillAreaPercent = 0;
//Rid scene of sprites
for(int x=0;x<=fillerNum;x++){
filler[x].body.setActive(false);
scene.detachChild(filler[x].sprite);
filler[x].active=false;
filler[x].scale=originalSpriteScale;
filler[x].body.setUserData("inactive");
}
levelText.setText("Level: "+Integer.toString(level));
fillersLeftText.setText("Balls left: "+Integer.toString(fillerCount));
percentFilledText.setText("0%");
fillerNum = -1;
Log.e("Level Complete","values reset");
randx = random.nextInt(650) + 25;
randy = random.nextInt(400) + 25;
randix = random.nextInt(10);
randiy = random.nextInt(10);
if(randix%2==0)
ix = 5;
else
ix = -5;
if(randiy%2==0)
iy = 5;
else
iy = -5;
Log.e("Level Complete","Creating destroyer");
destroyer[destroyerNum] = new Ball(randx, randy, destroyerTR, getVertexBufferObjectManager(), ix, iy); //crashes here
Log.e("Level Complete","complete"); //This line never reached.
}

You should use addr2line tool as described here and lookup these two addresses in your library to find what causes the crash:
#02 pc 00026558 /data/data/com.prattia.webs.testgfx5/lib/libandenginephysicsbox2dextension.so
#03 pc 00013e7c /data/data/com.prattia.webs.testgfx5/lib/libandenginephysicsbox2dextension.so
So under Windows you should:
Copy the library from device:
adb pull /data/data/com.prattia.webs.testgfx5/lib/libandenginephysicsbox2dextension.so C:\
Run addr2line tool for it using command line:
cd %PATH_TO_YOUR_NDK%\toolchains\arm-linux-androideabi-4.4.3\prebuilt\linux-x86\bin
arm-linux-androideabi-addr2line -C -f -e C:\libandenginephysicsbox2dextension.so
Enter adress by adress:
00026558 [ENTER]
> here will be function name and line
00013e7c [ENTER]
> and again
Note: running this tool under Windows may give you less information than under Linux, so you may choose to install the distro as a virtual machine and follow instructions from the link to original answer above.
Another (easier?) way is to use ndk-stack:
Run ndk-stack:
cd %PATH_TO_YOUR_NDK%
ndk-stack -sym C:\libandenginephysicsbox2dextension.so -dump C:\dump.txt
