Access denied finding proper         


        

Answer 1

I had the same problem with the Camera 1 API on my Test device "LG V30". I found out, that this message (Access denied finding property "camera.hal1.packagelist") appeared when I opened the camera like this:

int numberOfCameras = Camera.getNumberOfCameras();
CameraInfo cameraInfo = new CameraInfo();
for (int i = 0; i < numberOfCameras; i++) {
    Camera.getCameraInfo(i, cameraInfo);
    if (cameraInfo.facing == CameraInfo.CAMERA_FACING_BACK) {
        camera = Camera.open(i);
        cameraId = i;
    }
}

Important is, that this only happened for the LG V30, which has 2 back cameras (numberOfCameras=3).

After some testing I found out, that this works for this device:

/** A safe way to get an instance of the Camera object. */
public static Camera getCameraInstance(){
    Camera c = null;
    try {
        c = Camera.open(); // attempt to get a Camera instance
    }
    catch (Exception e){
        // Camera is not available (in use or does not exist)
    }
    return c; // returns null if camera is unavailable
}

The example code above will access the first, back-facing camera on a device with more than one camera. Here you can find a detailed description.
