Question

I have an Android application with the following logic of activities execution:

if FIRST_RUN: SplashScreeen -> Logon -> MainScreenTabHost

if PUSH:

1. Not Running: SplashScreeen -> Logon -> MainScreenTabHost
2. Running: MainActivity receives a message

I can’t figure out how to achieve this. My source code for NotificationBar item:

Notification notif = new Notification(R.drawable.ic_launcher, "Text in status bar", 
System.currentTimeMillis());
Intent intent = new Intent(this, MainScreenTabHost.class);//HERE PROBLEM
PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);
notif.setLatestEventInfo(this, "Notification's title", "Notification's text", pIntent);
notif.flags |= Notification.FLAG_AUTO_CANCEL;
this.notificationManager.notify(1, notif);

This code always runs application MainScreenTabHost, but if application is not running it makes some init in Logon screen.

My question is: How can I check that application is running and if it’s not then create an Intent to run Splash screen and cycle for FIRST RUN? On the other hand, if application is running I just want to send an Intent (maybe a Broadcast) for some operations.

And one thing, my service is not always running because it is run by a broadcast intent from Push Notification.

Hm, i found next solution:

// Check current activity
        ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);

        List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(1);

        ComponentName componentInfo = taskInfo.get(0).topActivity;
        if (componentInfo.getPackageName().equals(this.getPackageName())) {
            Intent broadCast = new Intent(MainScreenTabHost.BROADCAST_ACTION);
            broadCast.putExtras(arg1.getExtras());
            sendBroadcast(broadCast);
        } else {

            this.sendNotif(arg1);
        }

So trick is: when fired onMessage method i check what activity currently on Top and if it’s part of mine – i just send broadcast to it. If NOT a show notification with SplashScreen intent.
