Things are now nicely modularized. Include this in your gradle:

dependencies {
    implementation 'com.wireguard.android:tunnel:1.0.20200329'
}

And then you'll be able to embed a tunnel in your Android app.

Documentation is available at:

We're working on improving these docs, but here's a small sample
