android - EglCore.release() of grafika cause application to terminate on GT-I9500 -


i refered continuouscaptureactivity of grafika implement demo records video mediacodec. demo worked fine in cases, crashed on gt-i9500 device when key pressed ( crash undetectable because assumed activity destroyed, used 'adb shell ps' check existence of demo process ). checked source code repeatedly, found code same continuouscaptureactivity of grafika. did following things:

  1. i installed apk of grafika in gt-i9500 device , launched continuouscaptureactivity, pressed key of phone, application did not crash, turned out grafika worked fine.

  2. i checked code again , found nothing suspicious.

  3. i created new android project , copyed continuouscaptureactivity.java , other necessary files such androidmanifest.xml, activity_continuous_capture.xml on grafika new project. modified androidmanifest.xml make continuouscaptureactivity main activity. compiled code , installed apk on gt-i9500 device. the same thing happened, application crashed after pressed key!!!

i confused problem, why did grafika work fine same code in new project crashed? anyhow believe there solution crash of demo because grafika worked fine. give me advices?

information can offer follows:

  1. i debuged application , found exact code caused crash, code https://github.com/google/grafika/blob/master/src/com/android/grafika/gles/eglcore.java#l191

  2. the crash strage, there no tombstone file generated , adb log limited:

06-15 14:39:33.853 i/activitymanager( 771): process com.example.grafikaaa (pid 13138) (adj 1) has died.
