我的应用程序正常运行，但日志显示“找不到ID为0xffffffff的程序包ID ff”。

Question

我有一个可以在模拟器和自己的设备上正常运行的应用程序。但是，当我在视图之间导航时，会收到消息

No package ID ff found for ID 0xffffffff.

每时每刻。我不知道这意味着什么或它来自哪里。

在日志中搜索，我还会发现以下消息：

I/low.wordscanne: The ClassLoaderContext is a special shared library.
2019-04-10 16:25:10.984 26226-26226/? I/chatty:uid=10099(com.myapp.erikbylow.wordscanner) identical 2 lines

2019-04-10 16:25:10.992 26226-26226/? W/low.wordscanne: Unsupported class loader

而且MainActivity - onCreate我总是得到这个警告

该应用程序至少可以在我的设备上运行，有人遇到过类似的事情吗？

我确实使用了aar-module从另一个项目中导入的内容。可以吗？

Answer 1

这也发生在我身上，我已经苦了几个小时才知道为什么会发生。好像从：

implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha3'

至：

implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha4'

解决了案件。告诉我您是否也遇到了问题（可能是更新中的错误）
