We have recently started beta testing our game through the play store. Nexus 7 users are reporting a crash on start, but I'm not sure how to debug it. That stacktrace in the dev console is shown below.
I am finding this particularly tricky to debug for two reasons,
- I don't have physical access to a nexus 7
- The stacktrace appears to show the crash occuring with libGLESv2_tegra.so, but its not giving me a line of java code to start from.
Can anyone give me some hints on how to debug this?
The game is 100% java, no NDK, and all the rendering is done with OpenGL ES 2.0
