Hi, You can run a *gRPC server inside an Android app*, exposing APIs like launching intents, accessing system services, or interacting with the Android framework. This allows *any gRPC-capable client* (Python, C++, Rust, etc.) to call the Android system *without using JNI.* *How It Works* 1. *Set up a gRPC server in Java/Kotlin* inside an Android Service. 2. *Expose Android API functionality* via gRPC endpoints. 3. *Handle incoming gRPC requests* and return results. 4. *Run the gRPC server as a Foreground Service* to ensure it stays alive. 5. *Connect from an external app or another stack* via a gRPC client.
