Manage multiple (Stable) AIDL clients

[Hoang Le Huy]

Hello team,

Currently, I'm implementing a AIDL HAL server (ndk backend - Android 11),

which will support multiple clients at runtime.

In my service, I need to manage all clients, and their callback interfaces in parallel.

For example: a client might register its callback interface multiple times,

but the server only stores one entry for that client. 

I looked at NDK Binder API, and even libbinder source, however,

could not find any public method or attribute which might help identify

the client.

I appreciate any idea, or potential solution for this use case.

Best Regards,

Le Huy Hoang
