Enable multidex.

Open project/app/build.gradle and add following lines.

defaultConfig {
    ...

    multiDexEnabled true
}

and

dependencies {
    ...

    implementation 'com.android.support:multidex:1.0.3'
}

2) Enable Jetifier.

Open project/android/app/gradle.properties and add following lines.

android.useAndroidX=true
android.enableJetifier=true
