A/libc Fatal signal 11 (SIGSEGV), GLSurfaceView Crash on Intel Atom x86 AVD

06-04 09:59:32.355: A/libc(2495): Fatal signal 11 (SIGSEGV) at 0x00002600 (code=1), thread 2508 (Thread-117)

This was a common error when stopping a OpenGL-ES app on Intel x86 AVD. Here's a quick solution (worked fine on JPCT-AE Engine):

- Open AndroidManifest.xml, add android:allowClearUserData="true" tag to the application node.

For now it's only available in portuguese language.

Android rom downgrade

posted Jul 5, 2012, 7:36 AM by Andres Jessé

Unfortunately my android device came with a very unstable rom, so i decided to downgrade it to a more stable version. I've choosed the factory 2.3.4 android release. To my surprise the "flash" process is not so easy as it seems, so i asked for help. I want to thank the GSMFans forum and specially the user GDInfo for the useful tips and video tutorials.
