Android Material and appcompat Manifest merger failed in react-native or ExpoKit

Question

I updated \'android.support:appcompat-v7\' to 28.0.0.

But it brought an error from the build.

Attribute application@appComponentFactory          


        

Answer 1

I found a solution through my search by referring to @MehulSolanki answer.

I add

tools:replace="android:appComponentFactory"
android:appComponentFactory="whateverString"

in my on AndroidManifest.xml

and update com.android.tools.build:gradl:

dependencies {
    classpath 'com.android.tools.build:gradle:3.2.1'
  }

And add this in your gradle.properties file

android.useAndroidX=true
android.enableJetifier=true

ERROR: [TAG] Failed to resolve variable '${animal.sniffer.version}'

ERROR: [TAG] Failed to resolve variable '${junit.version}'

In case of above error

1. File -> Invalidate Caches / restart
2. Build -> Clean project

error: package android.support.annotation does not exist error: cannot find symbol class Nullable

In case of above error

Add implementation 'androidx.annotation:annotation:1.1.0'

change import android.support.annotation.Nullable; => androidx.annotation.Nullable;

change import android.support.annotation.NonNull; => androidx.annotation.NonNull;

Compile version and target version should be 28.
