- Now add this to your application module’s build.gradle
apply plugin: 'com.android.application' // or apply plugin: 'java' apply plugin: 'me.tatarka.retrolambda'

So things like this:
button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { log("Clicked"); } });
Become this:
button.setOnClickListener(v -> log("Clicked"));
