Question

我有电话号码活动以及电话号码控制器类我已经在我的标准方法中定义了checkpermission和requestpermission，并从控制器类调用它们，如下所示：

public static boolean checkPermission ( Context context ) {
    Log.e ( "checkPermission: " + context.getClass ( ) );
    if (ContextCompat.checkSelfPermission (context,
          Manifest.permission.READ_EXTERNAL_STORAGE != PackageManager.PERMISSION_GRANTED)
        return true;
    return false;

public static void requestPermission ( Activity activity ) {
        Log.e ( "AA---->>>", "requestPermission: " + activity.getClass ( ) );
        ActivityCompat.requestPermissions ( activity,
                new String[]{Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE},
                1);
}


 calling from controller:

boolean isPermissionGiven = StandardMethods.checkPermission ( phoneActivity );
    if ( !isPermissionGiven ) {
       StandardMethods.requestPermission ( phoneActivity );
    }


gives this Error :

E/Utkarsh---: checkPermission: class .PhoneNumberActivity
E/Utkarsh---->>>: requestPermission: class.PhoneNumberActivity
V/FA: Activity resumed, time: 80577484
V/FA: Screen exposed for less than 1000 ms. Event not sent. time: 19
V/FA: Activity paused, time: 80577499
E/Utkarsh---: checkPermission: class.PhoneNumberActivity
V/FA: Activity resumed, time: 80577732

我要求的许可是：

public static boolean checkPermission ( Context context ) {

if ( hasPermission ( context, Manifest.permission.READ_EXTERNAL_STORAGE ) )
                return true;
else if ( hasPermission ( context, Manifest.permission.WRITE_EXTERNAL_STORAGE ) )
                return true;
else if ( hasPermission ( context, Manifest.permission.READ_SMS ) )
                return true;
else if ( hasPermission ( context, Manifest.permission.SEND_SMS ) )
                return true;
else if ( hasPermission ( context, Manifest.permission.RECEIVE_SMS ) )
                return true;
            return false;

}

private static boolean hasPermission ( Context context, String flag ) {
            return ContextCompat.checkSelfPermission ( context, flag ) != PackageManager.PERMISSION_GRANTED;
        }

“SEND SMS”存在一些问题权限，它总是发送权限未授予我不知道为什么，虽然我不是在我的应用程序发送短信所以我删除它。删除这个使我的错误消失了。在那之前，错误一直无限，我不知道为什么它有所帮助。虽然如果写在活动内部，相同的权限也很有效。现在他们处于非活动类（标准方法）。

请某人提供原因
