当我迁移到 AndroidX 时，我得到 java.lang.RuntimeException: Unable to start activity ComponentInfo
When I migrated to AndroidX I am getting java.lang.RuntimeException: Unable to start activity ComponentInfo
最近我将应用程序推送到上线，但它无法在 android 9 及更高版本上运行。所以，我升级了 android studio 到 2020.3.1，更新了插件，迁移了代码到 AndroidX。从那时起，我面临以下问题。
这里是运行时的错误

我不知道如何解决这个问题。有什么建议吗？
只需清理您的项目并重建您的项目。
您使用的 Calligraphy 版本已过时，您需要更新 Calligraphy 3 以支持 android 10 及更高版本。
