Question

当运行react-native run-android时，出现以下异常... 运行良好，我做了一个git pull并做了npm ci，之后就来了。新的拉动也没有变化。实际上，对于执行git冒号之后的问题也同样如此。而且它在MAC中运行良好。请帮助我被卡住。

失败：构建失败，并出现异常。

* What went wrong:
Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
        is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
        Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:13:5-33:19 to override.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Answer 1

我解决了这个问题

npm uninstall react-native-device-info

然后

npm install --save react-native-device-info

最新版本应为2.1.2

Answer 2

将此添加到您的app / build.gradle依赖项：

configurations.all {
        resolutionStrategy {
            force 'com.google.android.gms:play-services-gcm:16.1.0'
            force 'com.google.android.gms:play-services-base:16.1.0'
            force 'com.google.firebase:firebase-core:16.0.9'
            force 'com.google.firebase:firebase-messaging:18.0.0'
    }
}

这基本上会迫使依赖gcm的第三方库（例如deviceinfo）使用16.1.0版本。
