Unfortunately, Camera has stopped

Question

Answer 1

Edit

Have you tried one of these ? It seems like your camera service didn't work properly / camera may be used for another application.

Failed to connect to camera service

Use the web camera in the android emulator

---

I use MacOSX by the way. i just say that, it works on my machine. I sent installed tools and logs. Maybe it helps.

VD Configuration

Nexus 5, API 23 (Both Cameras are selected)

When i start the emulator, it gives warning in the log but at in the end it worked.

Logs

WARNING: Camera name 'webcam0' is not found in the list of connected cameras.

Answer 2

With Android API >= 23, you must ask for permission in code like:

int REQUEST_PERMISSION= 100;
int cameraPermission = this.checkSelfPermission(Manifest.permission.CAMERA);
if (android.os.Build.VERSION.SDK_INT >= 23) {
  if (cameraPermission != PackageManager.PERMISSION_GRANTED  ) {


      this.requestPermissions(
            new String[]{Manifest.permission.CAMERA },
            REQUEST_PERMISSION
    );
  }
}

Now ok to run.
