在升级Android Studio至3.4版本后遇到代码重复类错误，如INotificationSideChannel$Stub在不同模块中重复定义。通过在gradle.properties文件中添加特定配置解决了该问题，确保了项目兼容性和稳定性。

android studio升级到3.4版本, 各种报错, 代码各种修改.

其中有一个这样的错误, 没有见过, 后来在StackOverflow看到了一样的报错,找到了解决方法;

解决方法:

# 需要在gradle.properties中添加下面两行代码
# 这是因为混合支持库。通过添加这些行选择androidX作为您的支持库

android.useAndroidX=true
android.enableJetifier=true
