在react native中更改为androidX

我正在尝试将我的

react native

项目更改为

androidx

。 我之所以想这样做，是因为我在尝试运行项目时突然出现了以下错误：

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

我读了一些关于这个问题的帖子，并试图添加以下内容：

android.useAndroidX=true
android.enableJetifier=true

因为当我使用堆栈跟踪时，我遇到了以下错误：

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

我将这一行添加到我的

local.properties

文件中，但当我这样做时，我发现我需要将所有

节点模块

文件更改为使用

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

我的本地版本：

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

我正在附加我的文件：

目前是否有解决此问题的方法？我无法突然运行我的项目

根本原因是迁移到

Androidx

，google play服务更新为

Androidx

如果您使用的是

real native info

，请升级。它将通过2.1.2解决您的问题

yarn uprade react-native-info@2.1.2

看

对这个问题的回答

对这个问题

应用说明：将

com.google.android.gms

升级到17.0.0将导致很多问题 问题

android/app/build.gradle中的这些行为我修复了它（基于）<代码>反应本机推送通知

依赖于导致故障的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本机推送通知

依赖项，可以检查androidx依赖项的位置：

cd-android&./gradlew应用程序：依赖项

（有关该方法的更多详细信息，请参阅。）

谢谢您的回答，我使用npm，反应本机信息是什么，我应该执行什么命令？正如您在我的gradle文件中看到的，没有提到反应本机信息…@jredikes

warn升级反应本机设备-info@2.1.2

和

cd-android&&gradlew-clean

我需要保留以下行：android.useAndroidX=true-android.enableJetifier=true还是删除它们？更重要的是，我的com.google.gms版本是4.1.0，而不是17…删除该部分似乎不错。如果需要此语法，

android.useAndroidX=true android.enableJetifier=false

您不能执行一个false和第二个true。。它们必须是相同的价值观任何人都有解决方案吗？我也遇到过这样的情况：-/@AsifAli你找到解决方案了吗？你知道为什么会这样吗？还没有@JJ Redikes，我想有些内部依赖项无法用android x编译。。需要单独查看每个依赖项许多库都受到新发布的google服务的影响。对我们来说，这是反应本机推送通知和反应本机设备信息。由于您的app/build.gradle中有第一个依赖项，请在此处检查此解决方案：。这为我们解决了问题
