title: How to check if user has given camera or location permissions (android) UNITY
body: <p>I really struggle with this since a while :( as I need an <strong>solution that works within UNITY3D.</strong></p>
  
  <p><strong>I need to check if the user has given the permission to access the Android device camera</strong> (and location on a second level).</p>
  
  <p>Normally the app start by <strong>asking for this permissions at launch, but if the user denies the access</strong> for the camera I need to know and check that later.</p>
  
  <p>Otherwise the user could hit the camera UI button I made and try to access the camera via webcamtexture... and that leads into a <strong>crash of the app.</strong></p>
  
  <p><strong>Since Android API 23 you cannot ignore or already grant permissions by changing the android manifest</strong> like I tried after reading several posts about that.</p>
  
  <p>Thank's to everyone who has an idea to solve this.</p>
