I have a TextureView based on Romain Guy's example which can be found here. On Android 4.3 and 4.4, after a few rounds of pausing and resuming the application, the application crashes and the only trace of an error is a fatal signal 11 in LogCat. I created a test application which uses Romain Guy's exact code to see if it was something I had done in my code and Romain's code crashes with the fatal signal 11, too.
I have determined that if I run the code with a Handler instead of a Thread, it does not seem to crash the application. The Handler should be running on the main UI thread (or at least I believe it is), which is perhaps suggesting it is a threading issue.
I have also determined that the crash occurs during a call to canvas.drawX (drawColor, drawBitmap, drawRect, etc...). Locking and unlocking the canvas does not seem to be an issue. I suspect that the thread is being cancelled while some other code is still using the canvas, but I am having a very difficult time tracking the issue due to a lack of any real exceptions being thrown and the crash being fairly inconsistent.
Any insights would be greatly appreciated.
