Android----Get the current app package name, the name of the current activity, and whether the system desktop, service class

1. Get the current app package name

public static String Getrunningactivityname (context context) {
Activitymanager activitymanager= (Activitymanager) Context.getsystemservice (Context.activity_service);
Full class name
String runningactivity=activitymanager.getrunningtasks (1). Get (0). Topactivity.getclassname ();
String contextactivity = runningactivity.substring (Runningactivity.lastindexof (".") +1);
return contextactivity;
}

2. Get the name of the current activity

public static String Getapppackagename (context context) {
Activitymanager Activitymanager = (activitymanager) context.getsystemservice (Context.activity_service);
List<activitymanager.runningtaskinfo> TaskInfo = activitymanager.getrunningtasks (1);
ComponentName componentinfo = taskinfo.get (0). topactivity;
LOG.D ("Lixx", "Current application:" + componentinfo.getpackagename ());
return Componentinfo.getpackagename ();
}

3, determine whether the system desktop

/**
* Determine if the current interface is desktop
*/
Private Boolean ishome () {
Activitymanager Mactivitymanager = (activitymanager) getsystemservice (Context.activity_service);
list<runningtaskinfo> RTI = mactivitymanager.getrunningtasks (1);
Return Gethomes (). Contains (Rti.get (0). Topactivity.getpackagename ());
}


/**
* Get app package names for apps that belong to the desktop
*
* @return Returns a list of strings that contain all the package names
*/
Private List<string> Gethomes () {
list<string> names = new arraylist<string> ();
Packagemanager Packagemanager = This.getpackagemanager ();
Intent Intent = new Intent (intent.action_main);
Intent.addcategory (Intent.category_home);
list<resolveinfo> ResolveInfo = packagemanager.queryintentactivities (Intent,
PACKAGEMANAGER.MATCH_DEFAULT_ONLY);
for (ResolveInfo Ri:resolveinfo) {
Names.add (Ri.activityInfo.packageName);
}
return names;
}

4, the typical service class

public class Floatwindowservice extends Service {


/**
* Used to create or remove suspended windows in the thread.
*/
Private Handler Handler = new Handler ();


/**
* Timer, timed to detect whether the suspended window should be created or removed at the moment.
*/
private timer timer;


@Override
Public IBinder Onbind (Intent Intent) {
return null;
}


@Override
public int Onstartcommand (Intent Intent, int flags, int startid) {
Turn on the timer and refresh every 0.5 seconds
if (timer = = null) {
Timer = new timer ();
Timer.scheduleatfixedrate (New Refreshtask (), 0, 500);
LOG.D ("Lixx", "===== timed refresh, monitor the status of the suspended window =====");
}
Return Super.onstartcommand (Intent, flags, Startid);
}


@Override
public void OnDestroy () {
Super.ondestroy ();
Service is terminated while the timer continues to run
Timer.cancel ();
timer = null;
}


Class Refreshtask extends TimerTask {


@Override
public void Run () {
Get the name of the current activity
String activity_name = Mywindowmanager.getrunningactivityname (Getapplicationcontext ());
LOG.D ("Lixx", "activity_name---->" + activity_name);
Get the application package name
String pck_name = Mywindowmanager.getapppackagename (Getapplicationcontext ());
LOG.D ("Lixx", "pck_name---->" + pck_name);

The current interface is the desktop, and no hover window is displayed, creating a floating window.
if (Ishome ()) {
Handler.post (New Runnable () {
@Override
public void Run () {
LOG.D ("Lixx", "desktop, remove the hover window!") ");
Mywindowmanager.removesmallwindow (Getapplicationcontext ());
}
});
}else if (! Textutils.isempty (Activity_name)) {
LOG.D ("Lixx", "Activity_name is not null");
if (MYWINDOWMANAGER.ISSHOWINGYKQ (activity_name) && pck_name.equals ("com.ysten.istouch.client.screenmoving ")){
Handler.post (New Runnable () {
@Override
public void Run () {
Mywindowmanager.createsmallwindow (Getapplicationcontext ());
}
});
}else{
Handler.post (New Runnable () {
@Override
public void Run () {
LOG.D ("Lixx", "Remote Control interface, remove the hover window!") ");
Mywindowmanager.removesmallwindow (Getapplicationcontext ());
}
});
}
}else{
Handler.post (New Runnable () {
@Override
public void Run () {
Mywindowmanager.removesmallwindow (Getapplicationcontext ());
}
});
}
}


}
