In  Android ASOP, I Have a Crash: 

I Don't Know why

Hi,

Can you provide more detail like what version of AOSP are you using, how are you calling the encoder and what input is causing the crash? This stacktrace (if that's what it is) looks corrupted as there's no path from regenerateAtlasForGanesh to ApplyFiltersAndEncode.
