Question

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

我不知道代码中的错误是什么，因为日志没有指向我的任何类文件。任何人都可以帮我解决这个问题吗？

更新项目级build.gradle文件后，我得到了不同的错误

这是我的gradle文件

Answer 1

升级到3.1时，我将所有库更新到最新版本并遇到了与您相同的问题。

我回滚了build.gradle文件并且编译没有问题。然后我一次更新了一个库，发现改造是导致问题的那个（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'

您也可以尝试使用回滚方法。

修改

您可以尝试将其添加到您的proguard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google“okhttp3.internal.platform.ConscryptPlatform：找不到引用的类org.conscrypt.OpenSSLProvider”

它引导我进行以下操作：https://github.com/square/okhttp/issues/3922

引导我到这个链接：https://github.com/square/okhttp/blob/5fe3cc2d089810032671d6135ad137af6f491d28/README.md#proguard（告诉我将上面的内容添加到proguard文件中）。

Answer 2

在下面使用

-dontwarn okhttp3。** -dontwarn okio。** -dontwarn org.conscrypt。**

如果使用Java 8，请在下面添加

-dontwarn retrofit2.Platform $ Java8

我已经将android studio版本更新为3.1 - 在运行应用程序时导致错误
