推荐答案

这意味着另一个应用程序正在后台运行，并且正在访问此图钉.如果一个应用在打开新应用之前没有完全停止，则可能会发生这种情况.

This means another app is running in the background and is currently accessing this pin. This may happen if one app is not fully stopped before a new one is opened.

您可以通过运行以下命令来查看所有已安装的应用程序:adb shell pm list packages -3

You can see all your installed apps by running: adb shell pm list packages -3

您可以通过运行adb shell am force-stop <package name>

卸载或强行停止恶意应用程序应该可以让您正确地控制它.

Uninstalling or force stopping the rogue app should allow you to properly get control of it.

正如评论所指出的那样，我没有包含执行卸载的命令. adb uninstall <package-name>

As a comment pointed out, I did not include the command to do uninstalling. adb uninstall <package-name>
