CheckSelfPermission始终返回权限被拒绝

Question

在Android M(Android 6)中,我正在使用该方法ActivityCompat.checkSelfPermission().

即使我在应用程序设置中手动启用了请求的权限,此方法的结果始终是"权限被拒绝".

这可能是什么原因？

  int smsPermission = ActivityCompat.checkSelfPermission(AuthActivity.this, Manifest.permission_group.SMS);

  if (smsPermission != PackageManager.PERMISSION_GRANTED) 
  {
      dialog.setCancelable(false);
      dialog.setMessage("dialog content");
      dialog.setPositiveButton("OK", new DialogInterface.OnClickListener()
      {
          @Override
          public void onClick(DialogInterface dialogInterface, int i)
          {
             ActivityCompat.requestPermissions(AuthActivity.this, new String[]{Manifest.permission.SEND_SMS}, Constants.REQUEST_SMS_PERMISSION);
             dialogInterface.dismiss();
          }
       });
       dialog.show();
   }

Answer 1

checkSelfPermission()获得许可(例如SEND_SMS),而不是权限组.
