In-app or Android System: Should your feature be built into your Android app or does it fit better as an Android system integration? We’ll provide detailed implementation steps, code snippets, and architectural insights to help you build your own intelligent Android applications.

In that case, we can switch from running an on-device model to using a cloud model instead. The automatic chat translation dynamically translates chat messages in real time to facilitate seamless communication, demonstrating custom hybrid inference logic.
