The app crashes for me too when i press save. No idea why, can't seem to find an exception for the app in logcat as well.

ask permission like below before open intent

if(ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED){ Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); startActivityForResult(intent, 1); } else { ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 2); }
