Solution 1:

I found this directly from android source and it works fine :)

finalActivityManageram= (ActivityManager)
                getSystemService(Context.ACTIVITY_SERVICE);

        final List<ActivityManager.RecentTaskInfo> recentTasks =
                am.getRecentTasks(3, ActivityManager.RECENT_IGNORE_UNAVAILABLE);
        for (inti=0, index = 0; i < 3 && (index < 3); ++i) {
            final ActivityManager.RecentTaskInforecentInfo= recentTasks.get(i);

            Intentintent=newIntent( recentInfo.baseIntent);
            if ( recentInfo.origActivity != null) {
                intent.setComponent( recentInfo.origActivity);
            }

            finalPackageManagerpm= getPackageManager();
            finalResolveInforesolveInfo= pm.resolveActivity(intent, 0);
            finalActivityInfoinfo= resolveInfo.activityInfo;
            finalStringtitle= info.loadLabel(pm).toString();

            Log.d("hello","  "+title+" "+info.packageName);
           finalImageViewiv= (ImageView)findViewById(R.id.imageView1);
           iv.setImageDrawable(info.loadIcon(pm));
                ++index;
            }

Solution 2:

Try this

ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        List<RunningTaskInfo> tasks = am.getRunningTasks(1);
        if (!tasks.isEmpty()) {
          ComponentName topActivity = tasks.get(1).topActivity;
          if (!topActivity.getPackageName().equals(context.getPackageName())) {
            returntrue;
          }
        }

It may useful to you to get second top activity.
