I'm writting a plug-in which defines a remote Service and provides a AIDL interface for 3rd party developers. How can I use this remote service to deal with defferent clients' concurrent requests? It is that service apk's activitys can keep status for each client, when they switched between each other, how to do it? This can be achieved using HandlerThread with Looper which maintains and service all the request no matter received from 100 applications. For this AIDL callback interface is also needs to be added as request will be furnished through these callbacks. SERVER APP IAidlService.aidl

It describes the mechanisms used by different types of android components to communicate with one another. 1) Intents are messages which components can send and receive. It is a universal mechanism of passing data between processes. With help of the intents one can start services or activities, invoke broadcast receivers and so on. 2) Bundles are entities of data that is passed through. It is similar to the
