Hi folks I am having difficulties with the lifecycle of the opengl context. While rendering my scene and the user hits the back button, home button or another application opens in front of my application, my app is still running in the background.
So when my application comes to the foreground later on (user relaunches it or the app that was opened on top of it finishes), my application crashes and leaves me nothing but a GL stack trace which i can't properly decipher. For rendering i use the GLSurfaceView and therefore delegate the onPause and onResume. The crash happens on the first call to glDrawElements(..). I have tried to reload my resource (geometry/textures etc.) on onSurfaceChanged but with or without reloading... The problem persists. This behavior can be observed on all AVD versions of the emulator as well as on the G1. Here is the gl stacktrace i get. Any help would be greatly appreciated. Thanks Moritz 02-07 10:33:26.768: INFO/DEBUG(28): *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** 02-07 10:33:26.778: INFO/DEBUG(28): Build fingerprint: 'generic/ google_sdk/generic/:2.1/ERD79/22607:eng/test-keys' 02-07 10:33:26.778: INFO/DEBUG(28): pid: 403, tid: 410 >>> com.comp.app <<< 02-07 10:33:26.788: INFO/DEBUG(28): signal 11 (SIGSEGV), fault addr 00000000 02-07 10:33:26.788: INFO/DEBUG(28): r0 00001401 r1 0000007e r2 00000000 r3 00001403 02-07 10:33:26.788: INFO/DEBUG(28): r4 0041d6c0 r5 00000000 r6 0000007e r7 0041d6c0 02-07 10:33:26.788: INFO/DEBUG(28): r8 00000000 r9 0000007b 10 00000000 fp 00137d10 02-07 10:33:26.798: INFO/DEBUG(28): ip 00000000 sp 46b3bd48 lr acc86014 pc acc850a0 cpsr 80000010 02-07 10:33:27.368: INFO/DEBUG(28): #00 pc 000050a0 /system/ lib/egl/libGLES_android.so 02-07 10:33:27.378: INFO/DEBUG(28): #01 pc 00006010 /system/ lib/egl/libGLES_android.so 02-07 10:33:27.388: INFO/DEBUG(28): #02 pc 0000f1f4 /system/ lib/libdvm.so 02-07 10:33:27.388: INFO/DEBUG(28): code around pc: 02-07 10:33:27.388: INFO/DEBUG(28): acc85090 5affffde e8bd87f0 e1a05002 e3a0a000 02-07 10:33:27.388: INFO/DEBUG(28): acc850a0 e5d51000 e1a00004 ebffff4a e5d51001 02-07 10:33:27.398: INFO/DEBUG(28): acc850b0 e1a06000 e1a00004 ebffff46 e5d51002 02-07 10:33:27.398: INFO/DEBUG(28): code around lr: 02-07 10:33:27.408: INFO/DEBUG(28): acc86004 e0845105 e1a02008 e1a0e00f e595f2c0 02-07 10:33:27.408: INFO/DEBUG(28): acc86014 e8bd81f0 e8bd81f0 e597098c e3a01b01 02-07 10:33:27.408: INFO/DEBUG(28): acc86024 e281c008 e150000c 1affffe1 eafffff7 02-07 10:33:27.418: INFO/DEBUG(28): stack: 02-07 10:33:27.418: INFO/DEBUG(28): 46b3bd08 3f800000 02-07 10:33:27.418: INFO/DEBUG(28): 46b3bd0c 00000000 02-07 10:33:27.418: INFO/DEBUG(28): 46b3bd10 40600000 02-07 10:33:27.428: INFO/DEBUG(28): 46b3bd14 3fc00000 02-07 10:33:27.428: INFO/DEBUG(28): 46b3bd18 41a00000 /dev/ ashmem/dalvik-LinearAlloc (deleted) 02-07 10:33:27.428: INFO/DEBUG(28): 46b3bd1c 3f800000 02-07 10:33:27.438: INFO/DEBUG(28): 46b3bd20 000000af 02-07 10:33:27.448: INFO/DEBUG(28): 46b3bd24 acf08c14 /system/ lib/libpixelflinger.so 02-07 10:33:27.448: INFO/DEBUG(28): 46b3bd28 0041d6c0 [heap] 02-07 10:33:27.448: INFO/DEBUG(28): 46b3bd2c acf091ac /system/ lib/libpixelflinger.so 02-07 10:33:27.458: INFO/DEBUG(28): 46b3bd30 0041d6c0 [heap] 02-07 10:33:27.458: INFO/DEBUG(28): 46b3bd34 acc9b850 /system/ lib/egl/libGLES_android.so 02-07 10:33:27.458: INFO/DEBUG(28): 46b3bd38 00001100 02-07 10:33:27.468: INFO/DEBUG(28): 46b3bd3c acc9540b /system/ lib/egl/libGLES_android.so 02-07 10:33:27.468: INFO/DEBUG(28): 46b3bd40 df002777 02-07 10:33:27.468: INFO/DEBUG(28): 46b3bd44 e3a070ad 02-07 10:33:27.468: INFO/DEBUG(28): #00 46b3bd48 acc9b008 /system/ lib/egl/libGLES_android.so 02-07 10:33:27.468: INFO/DEBUG(28): 46b3bd4c acc9b018 /system/ lib/egl/libGLES_android.so 02-07 10:33:27.468: INFO/DEBUG(28): 46b3bd50 0000007e 02-07 10:33:27.468: INFO/DEBUG(28): 46b3bd54 0041d6c0 [heap] 02-07 10:33:27.468: INFO/DEBUG(28): 46b3bd58 00000000 02-07 10:33:27.468: INFO/DEBUG(28): 46b3bd5c 42f28e48 02-07 10:33:27.468: INFO/DEBUG(28): 46b3bd60 42f28e30 02-07 10:33:27.478: INFO/DEBUG(28): 46b3bd64 acc86014 /system/ lib/egl/libGLES_android.so 02-07 10:33:27.478: INFO/DEBUG(28): #01 46b3bd68 46b3bda8 02-07 10:33:27.478: INFO/DEBUG(28): 46b3bd6c 00000000 02-07 10:33:27.478: INFO/DEBUG(28): 46b3bd70 42aadedc /data/ dalvik-cache/sys...@framework@[email protected] 02-07 10:33:27.488: INFO/DEBUG(28): 46b3bd74 42f28e58 02-07 10:33:27.488: INFO/DEBUG(28): 46b3bd78 46b3bd88 02-07 10:33:27.488: INFO/DEBUG(28): 46b3bd7c ad00f1f8 /system/ lib/libdvm.so 02-07 10:33:28.908: DEBUG/Zygote(30): Process 403 terminated by signal (11) -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
