// I forked this code from- http://www.piwai.info/chatheads-basics/
// Chat head is displayed from a service. 
// uses a permission: 	<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
// This is a service so it needs to be declared in manifest: 		<service android:name=".ChatHeadService" />
// Whenever you need to display the chat head, just start the service
// example: startService(new Intent(context, ChatHeadService.class));

public class ChatHeadService extends Service {

	private WindowManager windowManager;
