Mark,
Your subject says "synchronous" - afaik, only content providers are
synchronous. Service startup / binding is asynchronous, binder requires
a service (although I could be wrong on this one), and so is
asynchronous as well. Intents are of course asynchronous too.
A content provider doesn't have to be backed by SQL, or to really
implement data storage - you could pass various commands encoded in the
URI, returning results in your own Cursor implementation.
If you are keen on using intents, though - your code is pretty close,
but you need to use startActivityForResult rather than startActivity, so
that you can retrieve the result (set with setResult) later. This can't
be used from a Service, only from an Activity, though.

Hi,
I've got an application, and I'd like to publish a way for third-party
services to get data from it. Ideally I could expose this through
intents, as in the following pseudocode:
// third party apps
class ThirdPartyService extends Service {
@Override
public void onCreate() {
Intent i = new Intent(this, "com.me.test.MyAppIntent");
Intent result = startActivity(i);
}
}
// part of my app
class MyAppIntent extends Activity {
@Override
public void onCreate() {
Intent i = new Intent();
i.putExtra("result", "hi there");
setResult(i);
finish();
}
}
The above won't work of course - I have some work done on this, just
wondering if anyone has any recommendations or best practices?
Thanks
