那些遇到过的问题

库类（来自 Android sdk）取决于程序类（同样，Android sdk）

Gak*_*ket 5 android proguard gradle gradle-plugin android-proguard

我们正在从 Android Gradle 插件 2.3.3 迁移到 Gradle 插件 3.0.1。我们的应用程序由应用程序模块和库模块组成。一些依赖项是可传递的（使用api关键字连接），但即使使用使它们成为非传递也implementation无济于事。将所有compile-type 依赖项更改为新依赖项后，调试构建运行良好。然而，使用 Proguard 的发布版本显示了数千个警告（在 2.3.3 上一切顺利）

特别是，我不明白为什么当库中的 Android 类依赖于程序中的 Android 类时我们会遇到这样的问题（这里只是几个例子）：

Warning: library class android.app.ActionBar$LayoutParams extends or implements program class android.view.ViewGroup$MarginLayoutParams
Warning: library class android.app.ActivityManager$TaskDescription extends or implements program class android.os.Parcelable
Warning: library class android.widget.Toolbar depends on program class android.view.ViewGroup$LayoutParams

总体而言，以下类型的警告不会出现在 Gradle 插件 2.3.3 上（因此，Proguard 已配置）：

Warning: there were 72 unresolved references to classes or interfaces.
         You may need to add missing library jars or update their versions.
         If your code works fine without the missing classes, you can suppress
         the warnings with '-dontwarn' options.
         (http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedclass)
Warning: there were 1373 instances of library classes depending on program classes.
         You must avoid such dependencies, since the program classes will
         be processed, while the library classes will remain unchanged.
         (http://proguard.sourceforge.net/manual/troubleshooting.html#dependency)
Warning: there were 1056 unresolved references to program class members.
         Your input classes appear to be inconsistent.
         You may need to recompile the code.

不会解决你的问题。您需要查看依赖关系树并找到导致问题的库。

例如在我的例子中是

+--- com.foursquare:foursquare-android-oauth:1.0.3
|    \--- com.google.android:android:4.1.1.4
|         +--- commons-logging:commons-logging:1.1.1
|         +--- org.apache.httpcomponents:httpclient:4.0.1
|         |    +--- org.apache.httpcomponents:httpcore:4.0.1
|         |    +--- commons-logging:commons-logging:1.1.1
|         |    \--- commons-codec:commons-codec:1.3
|         +--- org.khronos:opengl-api:gl1.1-android-2.1_r1
|         +--- xerces:xmlParserAPIs:2.6.2
|         +--- xpp3:xpp3:1.1.4c
|         \--- org.json:json:20080701

所以你需要排除这个库的 com.google.android

implementation ('com.foursquare:foursquare-android-oauth:1.0.3'){
        exclude group: 'com.google.android'
}

快速修复： 我在升级到 Gradle 插件 3.0.0 时遇到了这个问题，一个快速解决方案是将其添加到您的 proguard 文件中，

-dontwarn android.**
Run Code Online (Sandbox Code Playgroud)

这应该也适用于 3.0.1。

建议： 当您使用的库未引用支持库中的 android 类或引用已弃用的类时，会发生这种情况。我的猜测是，

com.github.tony19:logback-android-core
Run Code Online (Sandbox Code Playgroud)

您正在使用的是导致此问题的原因，您可以删除此依赖项并尝试重建。如果这没有帮助，您可以尝试删除您正在使用但最近未更新的任何其他库。
