 Android **WILL NOT** execute your configured ```callbackFn```.  The plugin manages sync-ing GeoLocations to your server automatically, using the configured ```url```, ```params``` and ```headers```.  Since the Android plugin must run as an autonomous Background Service, disconnected from your the main Android Activity (your foreground application), the background-geolocation plugin will continue to run, even if the foreground Activity is killed due to memory constraints.  This is why the Android plugin cannot execute the Javascript ```callbackFn```, since your app is not guaranteed to keep running -- syncing locations to the server must be handled by the plugin.
 
-The Android plugin sends an HTTP POST to your configured ```url``` with ```Content-Type: application/json```.  The JSON location-data is encoded into the Request Body.  PHP people have [trouble with this](https://github.com/christocracy/cordova-plugin-background-geolocation/issues/50).  In PHP, find the raw JSON body with ```$data = file_get_contents('php://input');```.
