在 react-native 中更改为 androidX

Question

我正在尝试将我的 react-native 项目更改为 androidx。 我想这样做是因为我在尝试运行我的项目时突然遇到了这个错误：

com.android.build.api.transform.TransformException: Error while generating the main dex list.

我正在阅读有关该问题的一些帖子，并尝试添加这些行：

android.useAndroidX=true
android.enableJetifier=true

因为当我使用堆栈跟踪时，我收到了这个错误：

Program type already present: androidx.versionedparcelable.CustomVersionedParcelable react native

我将此行添加到我的 local.propeties 文件中，但是当我这样做时，我发现我需要更改所有 node-module 文件以使用 androidx

此外，我试图将包 react-native-device-info 更新到最新版本 2.1.2，但结果仍然相同...

我的 react 原生版本：

react-native-cli: 2.0.1
react-native: 0.50.4

我正在附加我的文件：

现在有什么办法可以解决这个问题吗？我突然无法运行我的项目

Answer 1

android/app/build.gradle 中的这些行为我修复了它（基于this GitHub comment）。 react-native-push-notification 依赖于导致失败的 androidx。

implementation(project(':react-native-push-notification')) {
    exclude group: 'com.google.android.gms'
}
implementation ("com.google.android.gms:play-services-gcm:16.1.0") {
    force = true
}
implementation ("com.google.android.gms:play-services-base:16.1.0") {
    force = true
}
implementation ("com.google.firebase:firebase-core:16.0.9") {
    force = true
}
implementation ("com.google.firebase:firebase-messaging:18.0.0") {
    force = true
}

如果您还没有 react-native-push-notification 依赖项，您可以检查您的 androidx 依赖项所在的位置：

cd android && ./gradlew app:dependencies

（有关该方法的更多详细信息，请参阅this comment。）

Answer 2

根本原因是相关迁移到Androidx，google play服务更新为androidX

如果您使用的是real-native-info，请升级。 2.1.2

将解决您的问题

yarn uprade react-native-info@2.1.2

应用注意：将com.google.android.gms 升级到 17.0.0 会导致很多 问题。
