// 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.
