We've been building a product called Doppl for several months. Its an Android-focused code sharing toolkit. The core tech is based on J2objc, with Gradle tools and popular Android libraries. We use this internally at touchlab, and the Droidcon app for the conference is built with it. This talk will be a preview about what and why it is. I'll be discussing the architecture, and why the Objective-C versions of retrofit and SQLiteDatabase are less scary than they sound.
