Hi!!
I have made two different packages for API Demo sample -
RemoteService in Service app package (Service.apk)
RemoteServiceBinding in Client app package(Client.apk)
(two different apk and two different projects in eclipse)
The Service app offer services which Client app binds to and utilizes.
The Service app gets started during BOOT COMPLETE.
This model works great when I do a full source build(without eclipse).
But when I make them under Eclipse, and my Client app invokes
registerCallback method on Service app interface, the
IRemoteServiceCallback instance(interface implemented in Client app)
is received null in Service app.
I have confirmed that mCallback (object passed) is not null.
I couldn't observe any error in logs. What could be the problem?
Thanks in advance
Ash

about

there.

mHandler.sendMessage(mHandler.obtainMessage(BUMP_MSG,

}

public void onServiceConnected(ComponentName className,
IBinder service) {
// This is called when the connection with the service has
been
// established, giving us the service object we can use to
// interact with the service. We are communicating with
our
// service through an IDL interface, so get a client-side
// representation of that from the raw service object.
mService = IRemoteService.Stub.asInterface(service);
mKillButton.setEnabled(true);
mCallbackText.setText("Attached.");
// We want to monitor the service for as long as we are
// connected to it.
try {
mService.registerCallback(mCallback);
} catch (RemoteException e) {
// In this case the service has crashed before we
could even
// do anything with it; we can count on soon being
// disconnected (and then reconnected if it can be
restarted)
// so there is no need to do anything here.
}

Service app code
######################
private final IRemoteService.Stub mBinder = new IRemoteService.Stub()
{
public void registerCallback(IRemoteServiceCallback cb) {
if (cb != null) mCallbacks.register(cb);
}
public void unregisterCallback(IRemoteServiceCallback cb) {
if (cb != null) mCallbacks.unregister(cb);
}
};
####################
PROBLEM---------
---------------------------------
The registerCallback gets invoked on Service app code but parameter
'cb' is null
