Some Little Hints:
OpenIntents is a very interesting project. It has a simple but important and helpful target: It wants to "[...] collect, design, and implement open intents and interfaces to make Android mobile applications work more closely together". And therefore the project also "[...] provides samples and free applications to demonstrate their usage". But the most astonishing point is that it successfully combines Open Source development and commercial activities - based on the Apache 2 licence. That's a kind the world should be.
The user expierences the succesful combination of interacting oi modules if he not only installs the applications but additionally the extensions.
Little Android Helpers...
