At this point, the Patchy project should compile cleanly. It will not run,

though, without the corresponding service.

Step #6: Implement the Service Side................................................

Finally, we need to make similar sorts of changes on the PostMonitor service.

First, modify TMonitor/AndroidManifest.xml to add an (so

Patchy can reference it from another process and package) and add the

INTERNET permission that JTwitter will need:

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="apt.tutorial.three"

android:versionCode="1"

android:versionName="1.0">

<uses-permission android:name="android.permission.INTERNET" />

<application android:label="@string/app_name">

<service android:name=".PostMonitor">

<intent-filter>

<action android:name="apt.tutorial.IPostMonitor" />

</intent-filter>

</service>

</application>

</manifest>

Next, change our binder object from being an instance of LocalBinder to

being an instance of an IPostMonitor.Stub anonymous inner class instance

as follows:

private final IPostMonitor.Stub binder=new IPostMonitor.Stub() {

public void registerAccount(String user, String password,

IPostListener callback) {

Account l=new Account(user, password, callback);

poll(l);

accounts.put(callback, l);

}

public void removeAccount(IPostListener callback) {

accounts.remove(callback);

}

};
