迁移到 AndroidX -“程序类型已存在：android.support.v4.media.MediaBrowserCompat

Question

我正在迁移到 androidX 并被此异常阻止。

AGPBI: {"kind":"error","text":"Program type already present: 
android.support.v4.media.MediaBrowserCompat$ConnectionCallback$StubApi21",
"sources":[{}],"tool":"D8"}

这就是我的应用程序依赖项的样子，

}

我已经尝试排除这个模块，如下所示，

exclude group: 'com.android.support', module: 'support-media-compat'

真的不确定这一点，因为像这样排除，可能会在运行时破坏功能。

任何建议将不胜感激。

Answer 1

1)。第一步应该是，使用获取依赖图/树，

gradlew app:dependencies --scan 

（在我的例子中，app 是模块名称）

2)。然后找出哪个正在使用受影响的模块，就我而言，它是 support-compat & support-media-compat in firebase-core强>依赖

排除受影响的模块有助于我编译，但由于在运行时使用排除的模块而导致崩溃，所以这不是正确的做法。

3)。这里的诀窍是，将所有依赖项更新到最新版本。

一旦你迁移到AndroidX，如果你遇到编译错误，记下它，只是注释掉那些行，实际上可以帮助你编译，但这不是正确的方法。您需要查看受影响的依赖项是迁移到 AndroidX 还是仍在使用支持库。

如果受影响的依赖项尚未迁移到 AndroidX，您将无能为力。，如果依赖项正在生成使用支持库的代码

Answer 2

我通过将此行添加到Gradle 中解决了这个问题。 Google Document

implementation "androidx.media:media:1.1.0"
