如何调试Android App授予特权权限？

<uses-permission android:name="android.permission.CAMERA" />

String[] permissions = {Manifest.permission.CAMERA};
int requestCode = 1;
requestPermissions(permissions, requestCode);

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    if (requestCode == 1) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            // 权限已授予，可以进行相应操作
        } else {
            // 权限被拒绝，无法进行相应操作
        }
    }
}

Log.d("TAG", "Debug message");
