我想我的应用程序有一个密码查询。这应该显示在每个应用程序启动时或恢复。​​

I want my app to have a password-query. This should be displayed every time the app is started or resumed.

因此​​，我宣布一个Startactivity显示密码提示。如果用户通过pressing'Back'硬件按钮关闭应用程序有些时候，一切都很好。 但是，如果用户暂停用pressing家的应用程序，该应用程序打开的活动之前显示不显示我的提示。

So I have declared a Startactivity that shows a password prompt. If the user closes the App by pressing 'Back'-hardware Button some times everything is fine. But if the user pauses the app by pressing 'Home' the app opens in the activity displayed before without showing my prompt.

1）什么是实现这个，因为我想最好的方法是什么？也许在做每一项活动的东西的onStop（），但是这就是所谓经常，不是只有当应用程序被家休息。

1)What is the best way to implement this as I want? Maybe doing something in OnStop() of each activity but this is called to often, not only when the app is closed by 'Home'.

2）是否有任何其他的方式来关闭应用程序，以便不显示我的PROMT？我在哪里要注​​意？

2)Is there any other way to close the app so that my promt is not displayed? Where do I have to pay attention?

感谢和问候， 直到

If you want to clear your activity stack everytime the user brings the app to fore-ground after pressing the home key and the passowrd screen to top the set android:clearTaskOnLaunch="true" in the application tag in the manifest and set <category android:name="android.intent.category.LAUNCHER" /> for your Startactivity
