I have been writing an emulator for a game console on Android. I had to use some C code (JNI) in order to gain good performance. I was excited that it ran at full speed (60 fps) on my G1 (Firmware version: 1.0; Builder number: kila_uk-user 1.0 TC5-RC8 116470). But after I have updated my G1 to a newer version (Firmware version: 1.5; Builder number: kila-user 1.5 CRB21 147201), it runs much slower (30 fps). After digging into the source code, I found out that the function android::Surface::lock(SurfaceInfo *info, bool blocking) is taking 12-15 milliseconds. But originally, it almost took no time to finish.
Is there any significant change about how surface is locked between the old and new versions? I was about to publish my app on Android market, but was very upset about the poor performance on the newer versions. Does anyone have any idea about this? Thanks. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "android-framework" group.
