Android 8.1 關機

之前發送Intent i = new Intent("android.intent.action.ACTION_REQUEST_SHUTDOWN");會報

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.ACTION_REQUEST_SHUTDOWN flg=0x10000000 (has extras) }

在8.1 用下面的代碼 ，記得app system 權限

 private void shutDown(){
        Intent intent = new Intent(Intent.ACTION_REQUEST_SHUTDOWN);
        intent.putExtra(Intent.EXTRA_KEY_CONFIRM, false);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);
    }
