Solution

Is there any way to find whether the android camera is in use?

Yes, `Camera.open()` will give you an Exception if Camera is in use.

From the docs,

/** 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
}
