Hello piplz,
While I searched for "CPU pegged" issue resolutions and found multiple
solutions, not one of them seemed to satisfy the following
circumstances.
Situation: Creating a live-wallpaper using strictly OpenGL ES 2.0
Problem: "CPU-Pegged" and then automatic device crash and restart
Cause: result of selecting "setEGLConfigChooser(8, 8, 8, 8, 0, 0)"
instead of "setEGLConfigChooser(5, 6, 5, 0, 0, 0)" (look up gl surface
etc.)
Logic problem 1: there aren't no EGL or GL errors.
Logic problem 2: device seems to be able to handle the 8888
configuration and shouldn't have any problems.
Device: Nexus One
Details: look up the last log excerpt (infos logged from application).
