最近我将我的 Android Studio 版本更新到了 3.1。更新后我的项目没有构建，而是给我以下错误:

我不知道我的代码中有什么错误，因为日志没有指向我的任何类文件。谁能帮我解决这个问题？
更新项目级别的 build.gradle 文件后，我得到了不同的错误

最佳答案
升级到3.1时，我把所有的库都更新到最新版本，遇到了和你一样的问题。
我回滚了 build.gradle 文件，它编译没有问题。 然后我一次更新一个库，发现改造是导致问题的原因(2.4.0 对我不起作用，但 2.3.0 有效)。
implementation 'com.squareup.retrofit2:converter-gson:2.3.0'
implementation 'com.squareup.retrofit2:retrofit:2.3.0'
你也可以试试回滚的方法。
编辑
您可以尝试将其添加到您的混淆文件中。 (它修复了我的错误，我可以毫无问题地更新到 2.4.0)
-dontwarn okhttp3.**
-dontwarn okio.**
-dontwarn javax.annotation.**
-dontwarn org.conscrypt.**
我注意到我的构建中有一些警告(见图)
我去谷歌搜索“okhttp3.internal.platform.ConscryptPlatform:找不到引用的类 org.conscrypt.OpenSSLProvider”
这让我想到了以下内容:https://github.com/square/okhttp/issues/3922
它引导我到这个链接:https://github.com/square/okhttp/blob/5fe3cc2d089810032671d6135ad137af6f491d28/README.md#proguard (它告诉我将以上内容添加到混淆文件中)。
关于android - 我已将 android studio 版本更新到 3.1 - 运行应用程序时导致错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/49554730/
