| // 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. |
