I'm trying to build my app as a system app so I added the sources to aosp.
I'm having troubles with AIDL files, related to the project structure. Here
is the relevant part of the project's structure

I have an activity that binds to an AIDL service.
The way the AIDL service is constructed, sometimes a IBinder is never
returned..
When that happens onServiceConnected is not called. Seems obvious.
But is there a way to detect that has happened? Is there another callback
I am missing?
Or i

You use AIDL when you have two distinct Android threads communicating.
Even the most basic messaging primitives are built on top of this (in
favor of UNIX IPC), such as

The underlying binder mechanisms keeps track of references across objects.
Native IBinder objects are reference counted; the framework holds a

I've been digging into Android IPC, recently and there's something puzzling
me.
Suppose I define a Parcelable that, as one of its arguments, takes a
callback listener which is also Parcelable.
Like this:

void start(in MyRequest req, in MyResponseListener listen
Try switching to:
Map success();
It may be that Map does not support out properly. I have never used
the out keyword in AIDL, as it leads to scary programming (relying on
side-effects applied to parameters).

Oh, and by the way, this affects two absolutely distinct projects which both
have AIDL files, and which used to build just fine. I have cleaned many times,
and even reimported a project, but it didn't help.

I have recently upgraded to SDK tools r10 and SDK platform tools r3. At first

the changes didn't help.
