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

Here is my gradle file:

dependencies {

    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'com.android.support:appcompat-v7:28.0.0'

    implementation 'com.android.support.constraint:constraint-layout:1.1.3'

    testImplementation 'junit:junit:4.12'

    androidTestImplementation 'com.android.support.test:runner:1.0.2'

    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

    // RxJava

    implementation 'io.reactivex.rxjava2:rxjava:2.1.9'



// RxAndroid

    implementation 'com.android.support:customtabs:28.0.0-alpha3'

    implementation "com.airbnb.android:lottie:2.8.0"



}

            </intent-filter>

        </activity>

    </application>



</manifest>

You have no problem with the Gradle or with the manifest, I'm also looking for the solution to this problem and in the manifest you do not have to change anything, rather use as minimum version of the SDK at least 21 and to avoid confiscations, try to go down version of Lottie (I'm using 2.7.0) and try adding in the Gradle this few lines:

implementation ('com.airbnb.android:lottie:2.7.0') {

    exclude group: 'com.android.support', module: 'support-v7'

    exclude group: 'com.android.support', module: 'support-v4'

    exclude group: 'com.android.support', module: 'design'

    exclude group: 'com.android.support', module: 'recyclerview'

    exclude group: 'com.android.support', module: 'transition'

}

Good luck bro! Update me!
