Listening To Your Friendsprivate void poll() {
Twitter client=new Twitter(); // need credentials!
List<Twitter.Status> timeline=client.getFriendsTimeline();for (Twitter.Status s : timeline) {
if (!seenStatus.contains(s.id)) {
// found a new one!
seenStatus.add(s.id);
}
}
}Of course, eventually, we will need to alert Patchy to the new statuses, but
we can leave that for the next tutorial.
Step #5: Set up the Public API............................................................
Finally, we need to begin the process of adding a public API that the Patchy
activity will be able to access.
First, we should define a Java interface that will represent our public API.
Create a src/apt/tutorial/IPostMonitor.java file with the following content:
package apt.tutorial;public interface IPostMonitor {
}Then, we need to create a "binder" that implements this API. The binder
will be supplied to Patchy when it binds to the PostMonitor service. So, add
the following inner class to PostMonitor:
public class LocalBinder extends Binder implements IPostMonitor {
void registerAccount(String user, String password) {
}
}Next, create an instance of our LocalBinder as part of initializing our
PostMonitor instance:
private final Binder binder=new LocalBinder();
