java - android bad token异常无法在WindowManager服务中添加窗口

Question

我正在尝试在 windowManager 服务中打开视频播放器。如果我使用图像而不是“VideoView”，一切正常。但是，如果我使用 VideoView，则会出现此异常。

01-06 12:17:46.237: E/AndroidRuntime(1129): android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application

我在谷歌上搜索并修复了所有问题，但仍然无法正常工作。

这是我的代码。
