I have found the cause of the problem,
android6.0 need request Permission.

[JeroenMols]

Great to hear!

[flyou]

if user did't give the permission of

the camera can prew but can not record video
when i open the camera will appear can not connect the camear service

Can somebody tell me how request permission for the activity? Because i'm asking and nothing changes. The "request" popup appears, i'm accepting and same "Camera in use" message appears.

Basically i'm using this in my MainActivity

ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, STORAGE_PERMISSION_CODE);
The MainActivity call the recordvideo() method after checking if the permission was conceded

final Intent intent = new Intent(this, VideoCaptureActivity.class);
            intent.putExtra(VideoCaptureActivity.EXTRA_CAPTURE_CONFIGURATION, configuration);
            intent.putExtra(VideoCaptureActivity.EXTRA_OUTPUT_FILENAME, videoUri);
            startActivityForResult(intent, REQUEST_VIDEO_CAPTURE);

I was having this trouble with the android default service to record videos, but my permission fixed the problem.
