Greetings, Dianne, Yi and others,
I have a need to do something similar, that is to access a backend
native service from the application.
Going through the messages here, there are several things that are
unclear to me. I'd really appreciate if you can provide more
information on them.

It just depends how you want to structure things
Hi Dave,
With respect to performance, which approach is more better? Because
all the other modules in Android such as Camera or Media Recorder
module all use native binding and JNI layer for java access.

Dianne,
BTW--- should we make the binder.c in the service_manager directory into a
library? So that people who write native service by C can reuse the code.
What do you think?

Thank you for the hint. I will try this out to see if I can make it work or

You are mixing two different things. You are creating a low-level core
system service, and then trying to connect to it as if it is a high-level
application service. If you are using service manager to publish it, you
need to use service manager (in Java ServiceManager) to access it.

Hi Dianne,
Thanks for the reply. Actually here is what I want to do:
On the service side (C code), reusing binder.c in the service_manager
directory. So my code will call
1. binder_open,
2. bio stuff to build an io block for adding service,
3.binder_call to add service to service_manager.
4. binder
If you are writing a low-level system service, the high-level Service API
(onBind() etc) is irrelevant. The aidl stuff is part of the primitive
Binder IPC stuff; Service is a much higher-level facility built on top of
it.

Ok, let me try out the AIDL part, it seems simpler. But I do have a
question about it and hope you could give more hits. I took a look on
the AIDL, it seems that on the service(server) side, we have to
implement onBind and other methods. For my case, does it mean that I
don't need to care about th
You can write AIDL to generate your Java binding, or you can write
your own native binding and put a JNI layer on top of that. If you
don't plan on calling your service from native code, AIDL is much
easier.

Hello,
I'm writing a service by C. My code calls binder to add a service
called "myservice" into servicemanager. And I can add "myservice"
without any problem. Also, when I run "/system/bin/service list", it
shows the service added by me. The question is -- What is the correct
