如何在android M上测试ActivityCompat.requestPermission？

这是我的java代码

public static void checkSinglePermissionCompat(final Activity activity,
                                               ActionNeedsPermission action, final String permission,
                                               final int permissionCode, String message) {
    int hasPermission = ActivityCompat.checkSelfPermission(activity, permission);
    if (hasPermission == PackageManager.PERMISSION_GRANTED) {
        action.performAction();
    } else {
        if (!ActivityCompat.shouldShowRequestPermissionRationale(activity, permission)) {
            showRationaleDialog(activity, message,
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog,
                                            int which) {
                            ActivityCompat.requestPermissions(activity, new String[]{permission}, permissionCode);
                        }
                    });
        } else {
            ActivityCompat.requestPermissions(activity, new String[]{permission}, permissionCode);
        }
    }
}

我的gradle文件

android {
compileSdkVersion "android-MNC"
buildToolsVersion "23.0.1"

defaultConfig {
    minSdkVersion "MNC"
    targetSdkVersion "MNC"
}
}

还有我的清单文件

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

<uses-permission-sdk-m android:name="android.permission.RECORD_AUDIO" />
<uses-permission-sdk-m android:name="android.permission.SEND_SMS" />

它只是回调权限被拒绝，没有显示系统权限请求对话框。有人能帮我吗？thx参考此样本
