问题
I have a part of code, i use this code four times, but the the sixth time, my application crash , i don't get any Exception or error code. The code is:
Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width, height, matrix, false);
I try to use:
try{
Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width, height, matrix, false);
}catch (Exception e){
e.printStackTrace();
e.getMessage();
}catch (OutOfMemoryError o){
o.printStackTrace();
o.getMessage();
}catch (AssertionError a){
a.printStackTrace();
a.getMessage();
} catch ( Throwable t ){
t.printStackTrace();
t.getMessage();
}
But nothings happen. I test my application in diferent dispositives, works fine in a Sony Xperia Z3, Moto G , GenyMotion with different simulators.
But dont works in my Motorola Moto Max.
The log console dont shows an error, but print some codes:

any suggestions ?
回答1:
I am pretty sure you are running out of memory for your device, which is why the 6th createBitmap is going to crash your application. Try the following:
try{
Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width, height, matrix, false);
} catch (Exception e) {
e.printStackTrace();
} catch (OutOfMemoryError e) {
e.printStackTrace();
}
This should properly give output for errors that are thrown. Let me know the output, you might need to manually call System.gc() to handle all the garbage collection youself.
