推荐答案

您可以设置安卓clearTaskOnLaunch =真正的属性您MainActivity在AndroidManifest.xml文件。请参见这里找到原因和更多的细节。我觉得这是最便捷的方式，以满足您的需求。

You can set the android:clearTaskOnLaunch="true" attribute for you MainActivity in the AndroidManifest.xml file. See here to find why and more details. I think this is the most convenient way to meet your demand.

编辑： 我只是测试，发现当您退出应用程序，并从应用程序的抽屉启动的应用程序，这仅适用（不长preSS回家，然后选择应用程序）。

I just tested and found this only works when you exit the app and launch the app from the app drawer(NOT long press on HOME and select the app).

如果你想永远把根系活力的前面，无论你什么时候重新启动应用程序，或从最近的画面。你可以声明机器人：launchMode =singleTask的根系活力，在这里，MainActivity

If you want to always bring the root activity to the front, no matter when you re-launch the app or from the recent screen. You can declare "android:launchMode="singleTask" for the root activity, here, the MainActivity.
