android - Droid's mediaserver dies on camera.takePicture() -
on motorola droid, firmware 2.1-update1, kernel 2.9.29-omap1, build # ese81
when attempting take picture, mediaserver dies segmentation fault.
i've tried putting takepicture in timer , running few seconds after camera initialization check race conditions, no change. calling camera.open() doesn't cause crash. also, calling camera.open() causes think autofocus motor make sort of ticking sound.
code breaks:
import android.app.activity; import android.os.bundle; public final class choppermain extends activity { public void oncreate(bundle savedinstancestate) { try { camera camera = camera.open(); catch (exception e) { e.printstacktrace(); } camera.takepicture( new camera.shuttercallback() { public void onshutter() { ; } }, new camera.picturecallback() { public void onpicturetaken(byte[] data, camera camera) { ; } }, new camera.picturecallback() { public void onpicturetaken(byte[] data, camera camera) { ; } }, new picturecallback() { public void onpicturetaken(byte[] data, camera camera) { system.out.println("ta da."); } } }); } catch (exception e) { e.printstacktrace(); } } } debug log:
