Question

我正试图将我的react-native项目更改为androidx。我想这样做是因为尝试运行项目时突然出现此错误：

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

我正在阅读有关此问题的一些帖子，并尝试添加这些行：

android.useAndroidX=true
android.enableJetifier=true

因为使用堆栈跟踪时出现此错误：

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

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

此外，我正尝试将软件包react-native-device-info更新到最新版本2.1.2，但结果仍然相同...

我的本机版本：

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

我正在附加文件：

现在是否有解决此问题的方法？我不能突然运行我的项目

Answer 1

根本原因是与向Androidx的迁移有关，Google Play服务已更新为androidX

如果您使用的是real-native-info，请升级。它将通过 2.1.2

解决您的问题

yarn uprade react-native-info@2.1.2

请参见here apply link
