我一直在构建一个包含许多活动的启动器应用程序。我希望主页按钮始终将用户带回 mainActivity，当按下主页键并且他们将我的应用程序设置为默认启动器时。这在 90% 的情况下都有效，但一段时间后 home 键最终停止工作。它会记录用户的按下，但不再将它们返回到 mainactivity。这是什么原因让我回避了……我们已经尝试了几个月以某种一致性重新创建错误，但无济于事。我们无法弄清楚是什么原因导致它停止工作.. 下面是我的清单。我想知道我是否缺少某种标志或其他东西。

我相信您遇到的问题可以通过将您的家庭更换的主要活动作为一项任务来解决。

为此，您可以在清单中添加以下行作为主要活动的一部分：launchMode="singleTask" 可以在此处找到有关此功能的说明。

现在，每当您的应用收到主页按键事件并且应用未运行时，它都会使用onCreate. 如果应用程序已经在前台运行或处于挂起状态，onNewIntent将在您的主活动中调用并将其带到最前面。
