Hi,
I opened file with SDL_RWFromFile from APK and tried to get it size with: SDL_RWseek(fh, 0, RW_SEEK_END); It’s working everywhere except android 4 03-23 12:19:54.464: E/dalvikvm(563): JNI ERROR (app bug): accessed stale local reference 0x1d200029 (index 10 in a table of size 3) 03-23 12:19:54.464: W/dalvikvm(563): JNI WARNING: 0x1d200029 is not a valid JNI reference 03-23 12:19:54.464: W/dalvikvm(563): in Lorg/libsdl/app/SDLActivity;.nativeInit:()V (CallIntMethodV) I added some traces and found out that app crashes in Android_JNI_FileRead at this line: int result = mEnv->CallIntMethod(readableByteChannel, readMethod, byteBuffer); I don’t understand all this JNI magic code, but found this article: http://android-developers.blogspot.com/2011/11/jni-local-reference-changes-in-ics.html Who may fix this bug? |

I believe the minimum supported API level is android-5, and I'm fairly certain there was at least a feature that required android-7 and up, though I can't recall what was it. -- Gabriel. |
