My app is using NDK (4r-crystax in my case) to proccess images from a camera. Problem is, it falls after few minutes of work. I guess there can be some memory leaks or something like that, but i dont know how to find out where the problem is. This is a log around this error:

Any ideas? Are there any usefull tools to help me find answer?

Is possible that Android kill on screen activity during proccessing a native code?

    If you’re using NDK r5 or greater, you can use the ndk-gdb script to run your program and connect to it via GDB. If your native code is crashing, it should drop you into the GDB command line, where you can examine the area of code that’s causing the problem.
