android Oreo Crash错误

我自横刀向天笑,去留肝胆两昆仑。这篇文章主要讲述android Oreo Crash错误相关的知识,希望能为你提供帮助。
该应用程序适用于以前版本的android,但不适用于Oreo,它是使用Firebase通知的Web视图。我对此有点新,但一直在研究这个错误,并没有发现任何类似的东西。

答案通道名称无效时会发生此异常。通过使用空的通道名称运行,我能够重现堆栈跟踪:
< string name="default_notification_channel_name"> < /string>

检查为default_notification_channel_name定义的值并将其更改为有效值。
另一答案AppCompactActivity是向后兼容但不向前兼容,您使用的是Android 8.0不支持的任何组件,还是Android Studio或最新的Oreo IDE。
