        '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")

Methods

參考

Methods

constructor()

constructor();

check()

check(permission);
返回一個解析為布爾值的promise，以確定是否已授予指定的權限。
參數:
NAMETYPEREQUIREDDESCRIPTION
permissionstringYes要檢查的權限。

request()

request(permission, [rationale]); 
提示用戶啟用權限並返回解析為字符串值的promise（請參閱上面的結果字符串），指示用戶是允許還是拒絕請求，或者是否不想再次詢問。

 如果提供了基本原理，此功能會檢查操作系統是否有必要顯示一個對話框，說明需要權限的原因(https://developer.android.com/training/permissions/requesting.html#explain) ，然後顯示系統權限對話框。
參數:
NAMETYPEREQUIREDDESCRIPTION
permissionstringYes請求的權限。
rationaleobjectNo帶標題和消息的對象。

requestMultiple()

requestMultiple(permissions);
提示用戶在同一對話框中啟用多個權限，並返回一個對象，其權限為鍵和字符串作為值（請參閱上面的結果字符串），指示用戶是允許還是拒絕請求，或者不想再次詢問。
參數:
NAMETYPEREQUIREDDESCRIPTION
permissionsarrayYes要求的權限數組。
