JNI ERROR (app bug): non-zero capacity for NULL pointer: 80000 in LibGDX

Question

As I have previously asked and some people have asked me to post the dalvik compiler log,here you go. Please notify me of where exactly the memory leak is taking place and the necessary changes i've to make in my code. Thanks!

Answer 1

Use the DDMS Memory Tracker and Heap Analyzer to figure out where your memory leak is. This backtrace is just the final allocation that hit the limit.

You are allocating a SpriteBatch in render, unless you have some lazy initialization code around that allocation, it seems rather sketchy. See https://code.google.com/p/libgdx/wiki/SpriteBatch.
