# EPF5 Week 1 Updates

I am able to build trin as a library for Android arm64 ABI.
I am able to embedd that library into an Android application and call functions from the Android side and return strings to the Android side.

### Current problems

When starting trin from the command line it automatically starts a Tokio reactor. That doesn't happen automatically when calling the library from Android. So I have to start a tokio reactor manually. I also need a way to pass data from trin to the Android app and vice versa.

1. Start Tokio reactor programmatically
2. Pass arbitrary data types from Android to trin via JNI
3. Return arbitrary data types from Rust code to the Android app via JNI
