title: Using FlashLight in appWidget and crashes when start app camera
body: <p>I have an app widget that is a flashlight.</p>
  
  <p>I turn on and turn off the flash inside a service.
  When I turn off the Flash release the camera to be used from other applications.
  Now if I have the flash on and open the camera application, the camera app stops because I'm still using the camera in my service.</p>
  
  <p>As I can release the camera automatically or detect when you want to be used from another application?</p>
  
  <p>Note : I am developing for api 16-22</p>
