我不断收到此错误，我不知道该怎么办了，请问您能帮忙吗？

Logcat 日志

好的，所以这是崩溃发生位置的 sn-p 我希望这是有帮助。我在构建中没有收到任何错误，我已经运行了通过调试器，我将电话部分更改为 WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY 但 Logcat 仍然出现相同的错误。我已经从logcat中给出的三行中追踪到了错误。

Line 182  wm.addView ( view, params );
Line 111  ShimejiView ();
Line 95 pause ();

我有错误？

【解决方案1】：

已弃用：

WindowManager.LayoutParams.TYPE_PHONE

您在 ShimejiView 方法中使用它。

“此常量在 API 级别 26 中已被弃用。对于非系统应用。请改用 TYPE_APPLICATION_OVERLAY。”

在文档中找到：看这里： https://developer.android.com/reference/android/view/WindowManager.LayoutParams

也许这是你的问题？

它与痕迹相匹配，如果我必须在上面投入资金，那就是它。如果不是这样，您应该查看窗口管理器文档，也许您会找到其他内容。
