在我的应用程序上运行ProGuard时，我一直收到错误消息（远低于此）。我的应用程序中确实有外部库文件。
这是我的proguard-android.txt文件代码

将其添加到您的proguard.cfg:
#### -- Picasso --
-dontwarn com.squareup.picasso.**
#### -- OkHttp --
-dontwarn com.squareup.okhttp.internal.**
#### -- Apache Commons --
-dontwarn org.apache.commons.logging.**
您的行-dontwarn com.squareup.okhttp.OkHttpClient.*与Warning: com.squareup.picasso.OkHttpDownloader不相关。
您可能尝试在proguard.cfg 中更改包名称
已添加：尝试添加proguard.cfg
-dontwarn
-injars bin/classes
-injars libs
-outjars bin/classes-processed.jar
-optimizationpasses 5
-dontskipnonpubliclibraryclasses

我理解proguard.cfg或proguard-project.txt（proguard-android.txt）文件之间的区别。请在两个文件中都尝试此代码。
检查您是否已经从/libs中删除了库，我删除了我放入的jar文件，它立即生成了我的apk！：）祝你好运
