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_loop to wait for requests. (Just do a quick prototype here, so no
multi-threads)
On the client side (java), send request to the service I built and receive
replies.
Now, if I run /system/bin/service list, I can see my service like this:
# /system/bin/service list
Found 43 services:
0 Binder.Test.IBindertest: []
But, on the java side, I can not really get the binder object for this
service. The bindService call failed with following error messages:
W/ActivityManager( 581): Unable to start service Intent {
action=Binder.Test.IBindertest }: not found
