关闭使用其他应用程序的服务导致的 IllegalArgumentException

Question

我正在编写一个在后台运行服务的 Android 应用程序，该服务利用OVERLAY_PERMISSION 来利用其他应用程序。它从我的主要活动上的按钮开始。到目前为止，一切顺利。

在我的服务中，在我的onDestroy() 中，我有一个if (myView != null) windowManager.removeView(myView);。当我从活动中调用 stopService 时，我得到一个错误，说：

java.lang.RuntimeException: Unable to stop service com.supernovaapps.cameralevel.LevelService@ed1633f: java.lang.IllegalArgumentException: View=android.widget.AbsoluteLayout{94fb155 V.E...... ......I. 0,0-0,0} not attached to window manager

如果我注释掉该行，我只能关闭服务。但是，如果我这样做，即使在服务关闭后视图仍保留在屏幕上，这不是我想要的。

关闭服务和分离视图的正确方法是什么？

Answer 1

看起来您向 windowManager 传递的视图与之前添加的视图不同。 只需将其传递给正确的视图，它就会起作用。
