清单合并失败 android.support.v4.app.CoreComponentFactory

Question

Error given:

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).

Gradle dependencies

dependencies {
implementation project(':react-native-image-resizer')
implementation project(':react-native-gesture-handler')
implementation project(':react-native-device-info')
implementation project(':react-native-camera')
implementation project(':react-native-agora')

Edit: This GitHub ticket helped me solve it, seemed to be an androidx and react-native problem. Got gms and firebase versions here

Answer 1

You need to migrate to AndroidX from andorid.support and android.arch dependencies. Your project is having conflicts as the error message says probably because of react native depencencies,

This link should be helpful

Take a look also here

TL;DR Get rid of all andorid.support and android.arch dependencies and use androidX instead

for example change

implementation 'com.android.support.constraint:constraint-layout:1.0.2'

into

implementation 'androidx.constraintlayout:constraintlayout:1.1.2' ,

second example change

implementation 'com.android.support:animated-vector-drawable:28.0.0'

into

implementation 'androidx.vectordrawable:vectordrawable-animated:1.0.0'

and do similar for all support dependencies

Answer 2

I solved it by including the following within app/build.gradle:

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

Put these flags in your gradle.properties

android.enableJetifier=true
android.useAndroidX=true

Changes in gradle :

implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation 'com.google.android.material:material:1.1.0-alpha04'
