React Native Android构建错误：清单合并失败：属性application @ appComponentFactory

Question

Suddenly got this build error (out of nowhere) which worked well in the morning.

I tried enabling AndroidX flags, but got ViewCompat class not found issue. So I rolled it back. I didn't make any changes since yesterday and it had no issues at all until today.

Is it because of this release ?

Would be great if someone could help out.

* 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:7:5-117 to override.

Answer 1

I just came across the same issue this morning as well.

I resolved it by updating both react-native-app-auth and react-native-device-info to their latest versions.

npm install react-native-app-auth && npm install react-native-device-info

OR

yarn add react-native-app-auth && yarn add react-native-device-info

No need to update to AndroidX.
