Android Can't Record Video with Front Facing Camera, Mediarecorder Start Failed: -19

Front Camera Record Video Failed

I finally solved the problem occasionally.

mMediaRecorder.setProfile(CamcorderProfile.get(1,CamcorderProfile.QUALITY_HIGH)); ==> mMediaRecorder.setProfile(CamcorderProfile.get(1,CamcorderProfile.QUALITY_LOW));

Now it works well. But I don't know exactly why it works and why it did not work before?

MediaRecorder failed when i stop the recording

Look at the documentation:

Note that a RuntimeException is intentionally thrown to the
application, if no valid audio/video data has been received when
stop() is called. This happens if stop() is called immediately after
start(). The failure lets the application take action accordingly to
clean up the output file (delete the output file, for instance), since
the output file is not properly constructed when this happens.

In other words: Dalvik throws the exception on purpose. You have to handle it to clean up after your app. You'd have to handle it like this:

private void stopRecording() {
    try {
        recorder.stop();
    } catch(RuntimeException stopException) {
        // handle cleanup here
    }
    camera.lock();
}

camera app not working?

You have to unlock the camera before creating MediaRecorder. And lock it before releasing it.

Try this code, it will work Have fun...
