I have been trying camera2 API. I have downloaded code from

https://developer.android.com/samples/Camera2Video/index.html to learn about how it works. It works fine till I stop recording. When I stop recording it runs following code.

private void stopRecordingVideo() {

// UI

mIsRecordingVideo = false;

mBtn_Video.setText(R.string.record);

// Stop recording

try {

mMediaRecorder.stop();

mMediaRecorder.reset();

}

catch (Exception e) {

e.printStackTrace();

}

Activity activity = getActivity();

if (null != activity) {

System.out.println("file " + getVideoFile(activity));

Toast.makeText(activity, "Video saved: " + getVideoFile(activity),

Toast.LENGTH_SHORT).show();

}

startPreview();

at mMediaRecorder.stop(); it throw following error

Any Idea what I am doing wrong. I spent few hours but couldn't find any solution.

Edit - I am using geneymotion emulator. The path I am using

file /storage/emulated/0/Android/data/com.gold.cameratwoapi/files/video.mp4

Thanks
