Migrating to Android Studio 3.0

Slides from my talk at Dutch Android User Group in July 2017

I also have a blogpost explaining the api vs implementation dependency: https://jeroenmols.com/blog/2017/06/14/androidstudio3/

21. @MOLSJEROEN
    MIGRATE DEPENDENCY CONFIGURATIONS
    ▸ Replace all compile with implementation
    ▸ Use api where you leak a module’s interface
    ▸ Replace provided configuration with compileOnly
    ▸ Replace apk configuration with runtimeOnly
    ▸ Other variants: debugApi, testImplementation
