 // The flow for geolocation permissions on Android needs to take into account
 // the global geolocation settings so it differs from the desktop one. It
 // works as follows.
 // GeolocationPermissionContextAndroid::RequestPermission intercepts the flow
 // and proceeds to check the system location.
 // This will in fact check several possible settings
 //     - The global system geolocation setting
 //     - The Google location settings on pre KK devices
 //     - An old internal Chrome setting on pre-JB MR1 devices
 // With all that information it will decide if system location is enabled.
 // If enabled, it proceeds with the per site flow via
 // GeolocationPermissionContext (which will check per site permissions, create
 // infobars, etc.).
 //
 // Otherwise the permission is already decided.
