Get ID of currently open camera

Question

How can I get the ID of the currently open android camera from an android camera instance? I can't see it in the parameters and getCameraInfo requires the id as a parameter.

Answer 1

There isn't a way to get the id of the currently open android camera. I ended up storing the id when I opened it.

Answer 2

It is just a number of the camera, so you loop through looking for the camera you want.

Here is a snippet to find the front-facing camera:

int cameraId = -1; int numberOfCameras = Camera.getNumberOfCameras(); for (int i = 0; i < numberOfCameras; i++) {   CameraInfo info = new CameraInfo();   Camera.getCameraInfo(i, info);   if (info.facing == CameraInfo.CAMERA_FACING_FRONT) {     Log.d(DEBUG_TAG, "Camera found");     cameraId = i;     break;   } }
