如何防止 Android Wear 活动有多个实例? [英] How do you prevent an Android Wear activity from having multiple instances?

问题描述

有时，大多数情况下，当我的 LG G 手表通过进入睡眠/昏暗模式自动关闭应用程序时，如果我通过转到开始菜单再次打开应用程序，则会打开两个活动实例(当我滑动时前一个在下面).

Sometimes, most of the time when my LG G watch closes the app automatically by going to sleep/dim mode, if I open the app again by going to the start menu there are two instances of the activity opened (when I slide one off the previous one is underneath).

这在手机中从未发生过，Android Wear 中的 Activity 就是这样工作的吗?我应该在 onPause() 中完成()"它们吗?

This never happens in a phone, is this how activities work in Android Wear? Should I "finish()" them in onPause()?

谢谢.

推荐答案

您是否查看了 AndroidManifest.xml 中 android:launchMode 活动的 android:launchMode 属性?

Have you looked at the android:launchMode attribute in the AndroidManifest.xml for the activity?

也许 android:launchMode="singleInstance" 会帮助你.
