Android Newly Taken Photo from custom camera does not appear in gallery

   Sometimes a newly taken photo from custom camera does not appear in the  
   gallery,for that you just need to send a broadcast 
  "ACTION_MEDIA_SCANNER_SCAN_FILE" so that the media scanner can scan   
   for the image you have saved

   Apply the below code in your activity class



   Intent ScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
                                       

ScanIntent.setData(uri); //captured image uri
sendBroadcast(ScanIntent);
