取消在另一个Android活动之上启动的React Native活动

Question

我试图弄清楚如何通过桥接公开一种方法来“杀死”一个本机应用程序。这是我们挂载运行我们的js代码的活动的方式。

    public void startReactApp(Activity activity, String configString) {
        if (activity == null) {
            Log.e("MobileSDK", "activity can't be null. returning.");
            return;
        }
        MobileSDKActivity sdkact = new MobileSDKActivity();
        sdkact.setConfigString(configString);

        Intent intent = new Intent(activity, MobileSDKActivity.class);
        activity.startActivity(intent);

        // Send Events to React Native after 5 seconds of starting React app.
        new Handler().postDelayed(new Runnable() {
            public void run() {
                // Send event to react native to enabled back button.
                MyReactBridge.sendEnableBackButton();
            }
        }, 5000);
    }

这是我在网上找到的解决方案。

void dismissReactActivity() {
        if (this.myActivityReference.get() != null) {
            Handler handler = new Handler(Looper.getMainLooper());
            handler.post(new Runnable() {
                public void run() {
                    ((MobileSDKActivity) myActivityReference.get()).onBackPressed();
                }
            });
        }
    }

有没有一种方法，而无需调用onbackpressed
