Question

有一个旧源需要更新，但显示错误:

Program type already present: android.support.v4.media.MediaBrowserCompat$CallbackHandler

gradle.properties文件包括:
android.useAndroidX = true android.enableJetifier = false
app.gradle :
compileSdkVersion 29 minSdkVersion 19 targetSdkVersion 29

根据您在问题中包含的内容，您正在尝试将AndroidX库添加到您的项目中。

无论如何，从多个依赖项中引用了较旧的支持库android.support.v4.media.MediaBrowserCompat。这就是您所看到的错误的含义。

要解决此问题，您应该运行gradlew app:dependencies来检索所有库的列表，并查看哪个库正在引用该库。

找到问题后，可以通过以下方式将库从依赖项中排除:

implementation ('library_name') {
       exclude module: 'android.support.v4.media.MediaBrowserCompat'
 }

我也将引用 documentation迁移到AndroidX，因为不再支持较早的支持库。
