Hello, I am currently developing an application that uses OpenGL with the Android 1.6 SDK. I am testing on both a Nexus One and an I/O Device (Magic).
The application runs perfectly on the Nexus. On the Magic, the application crashes >50% of the time on the first frame with a segmentation fault (see end of post). If it does not crash immediately, it runs fine and exits normally. The crash occurs when calling glDrawArrays for one of my vertex buffer objects. Oddly, when I enable lighting and one light, the application no longer crashes. Unfortunately this is not a solution because the application runs too slowly with lighting. I have found reports of crashing with vertex buffer objects when using non-direct buffers, but I am using direct buffers. For debugging, I modified my code to Log each gl call before it was made. Everything looks fine to me but maybe I'm doing something wrong: http://p5ui5jjnxq.pastebin.com/m2e2c1754 Does anyone have any idea what could be causing the segmentation fault? Any ideas why lighting would affect it, or why everything is fine on the Nexus? Is there something in addition to using direct buffers that needs to be done when using vertex buffer objects? Thanks ----------------------------------------------------------------------------------------------------------------------------------------------------------- *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** Build fingerprint: 'google_ion/google_ion/sapphire/sapphire:1.6/ DRC83/14721:user/test-keys' pid: 536, tid: 553 signal 11 (SIGSEGV), fault addr 001fa000 r0 001b51b8 r1 001f9ff8 r2 00000003 r3 001b9e70 r4 001f9ffc r5 001b9e74 r6 00000014 r7 000003ff r8 00000000 r9 001b9e58 10 00000003 fp 001b51a4 ip 00000002 sp 44847d08 lr 8042b8dc pc 8043fdd8 cpsr 20000010 #00 pc 0003fdd8 /system/lib/libhgl.so #01 lr 8042b8dc /system/lib/libhgl.so stack: 44847cc8 001af0e0 [heap] 44847ccc 001177e0 [heap] 44847cd0 4210aecc 44847cd4 8043bac0 /system/lib/libhgl.so 44847cd8 001af0e0 [heap] 44847cdc 00000000 44847ce0 001b00e0 [heap] 44847ce4 804251a0 /system/lib/libhgl.so 44847ce8 001177e0 [heap] 44847cec 00984300 44847cf0 001b5198 [heap] 44847cf4 001af0e0 [heap] 44847cf8 001afbdc [heap] 44847cfc 00000005 44847d00 df002777 44847d04 e3a070ad #00 44847d08 00000400 44847d0c 001177e0 [heap] 44847d10 00989300 44847d14 001b5198 [heap] 44847d18 001af0e0 [heap] 44847d1c 001afbdc [heap] 44847d20 00000000 44847d24 00001000 44847d28 00000008 44847d2c 00000000 44847d30 00000000 44847d34 001af0e0 [heap] 44847d38 001b00e0 [heap] 44847d3c 001177e0 [heap] 44847d40 4210aecc 44847d44 4210aeb8 44847d48 000003c0 44847d4c 8041f79c /system/lib/libhgl.so -----------------------------------------------------------------------------------------------------------------------------------------------------------
