Android dependency 'androidx.appcompat:appcompat' has different version for the compile (1.0.0) and runtime (1.0.2) classpath. You should manually set the same version via DependencyResolution code example

Example: Android dependency 'androidx.core:core' has different version for the compile (1.0.2) and runtime (1.1.0) classpath. You should manually set the same version via DependencyResolution

I solved it by upgrading my gradle dependency in the android/build.gradle file: classpath 'com.android.tools.build:gradle:3.3.1' (I was previously on version 3.2.1)
