问题描述
好的开始，我在这里尝试了所有其他答案（一些示例here，here），以至于我什至转到了 Google 搜索的第 5 页。
问题
当我设置 targetSdkVersion <= 28 时，我的应用程序运行良好，但如果我将其设置为更高的值 (29,30)，Android 10 设备的应用程序会在启动时崩溃。我没有任何书法库，我的文件中没有任何 abc_screen_simple 布局。非常感谢任何帮助。

解决方法
多亏了@CommonsWare comment，我才能通过删除来解决这个问题
implementation 'com.asha.nightowllib:nightowllib:0.2'
由于某种原因，这个库是应用在 Android 10 设备上崩溃的原因。
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Object java.lang.reflect.Field.get(java.lang.Object)' on a null object reference

对于将来可能发生类似崩溃的任何人，请查看您的堆栈跟踪以查找对您添加的库的任何引用，这可能是罪魁祸首。
