    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        // Prevent screenshot
        AppSafer.INSTANCE.preventScreenshot(window)

        // App Safer start

    func initAppSaferExample() {
        // APP_SAFER_KEY generated when registering an app to the Console
        let result = AppSafer().initAppSafer(AppSaferDelegator.delegator, serviceCode: "ncloud", key: "<APP_SAFER_KEY>")

        NSLog("initAppSafer() result: %d", result);

        if(result == SUCCESS) {
            // init success
        } else if(result == FAIL) {
