 *
 * `PermissionsAndroid` provides access to Android M's new permissions model.
 * Some permissions are granted by default when the application is installed
 * so long as they appear in `AndroidManifest.xml`. However, "dangerous"
 * permissions require a dialog prompt. You should use this module for those
 * permissions.
 *
 * On devices before SDK version 23, the permissions are automatically granted
 * if they appear in the manifest, so `check` and `request`
 * should always be true.
 *
 * If a user has previously turned off a permission that you prompt for, the OS
 * will advise your app to show a rationale for needing the permission. The
 * optional `rationale` argument will show a dialog prompt only if
 * necessary - otherwise the normal permission prompt will appear.
 *
 * ### Example
 * ```
 * import { PermissionsAndroid } from 'react-native';
 *
 * async function requestCameraPermission() {
 *   try {
 *     const granted = await PermissionsAndroid.request(
 *       PermissionsAndroid.PERMISSIONS.CAMERA,
 *       {
 *         'title': 'Cool Photo App Camera Permission',
 *         'message': 'Cool Photo App needs access to your camera ' +
 *                    'so you can take awesome pictures.'
 *       }
 *     )
 *     if (granted === PermissionsAndroid.RESULTS.GRANTED) {
 *       console.log("You can use the camera")
 *     } else {
 *       console.log("Camera permission denied")
 *     }
 *   } catch (err) {
 *     console.warn(err)
 *   }
 * }
 * ```
