Android Manifest merge error

Hello,

I am facing the following error:

Task :app:processDebugManifest FAILED /Users/my-user/Documents/pushproject/android/app/src/debug/AndroidManifest.xml:22:18-91 Error: 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.

See http://g.co/androidstudio/manifest-merger for more information about the manifest merger.

My OS and settings are: OS: Mac Platform: Android React Native version: 0.59.10 RN Push Notifications version: 3.1.3 Device: Moto G6 Android Pie(9.0)

Steps to reproduce:

1. Install RN -v 0.59.10
2. react-native run-android
3. npm install --save react-native-push-notification
4. react-native link react-native-push-notification
5. Did not change the App.js. It was left untouched.
6. react-native run-android There is when the error occurs. Note that I did not even started to use the RN push notification module. I just installed and linked it, then react-native run-android to see if everything still running ok, but it is not.

@mAlaliSy you saved me bro! after hours i finally could build my project but with a little bit more changes.

First: go to the ‘node_modules\react-native-push-notification\android\build.gradle’ and add these two lines:

def DEFAULT_GOOGLE_PLAY_SERVICES_VERSION = "+"
def DEFAULT_FIREBASE_MESSAGING_VERSION = "+"

then go to ‘Your_project_folder\android\app\build.gradle’ and replace implementation project('react-native-push-notification') with

compile (project(':react-native-push-notification')) {
        exclude group: "com.google.android.gms", module: "play-services-gcm"
        exclude group: "com.google.firebase", module: "firebase-messaging"
 }

After hours and hours and a lot of attempts, this is what worked so far. In android/app/build.gradle use: dependencies { implementation(project(":react-native-push-notification"), { exclude group: "com.google.android.gms" exclude group: "com.google.firebase" }) }

In android/build.gradle use:

ext{ ... googlePlayServicesVersion = "16.0.0" firebaseVersion = "17.3.4" ... }
