Anyone have a good use case for using channels on Android? I'm trying to learn it, but I can't think in any good reason to use it on Android (Not saying that it doesn't exists tho)

Callbacks hells like Camera2 or BluetoothGatt (for BluetoothGatt, an open source library I worked on already exists for this: https://github.com/Beepiz/BleGattCoroutines)

o observe changes in a DB for instance

Here’s how I’m using channels on android currently for work: https://medium.com/@rocketwagon/presenter-as-a-function-reactive-mvp-for-android-using-kotlin-coroutines-442fc4c77119

- Channels (directly) to wrap callbacks and make it readable.
- Actors to confine mutability, and so, remove synchronize calls

@dekans if you like that definitely check out @louiscad’s libraries for bluetooth

Aha, great 🙂

I already use channels to hide callback API
