ActivityManager.getRunningTasks is deprecated android

I am working on push notification in android where i am using a below method to show notification, but the problem is that now ActivityManager.getRunningTasks(1); is being deprecated. From one stackoverflow question i read that: " you can use

getAppTasks()
returning a
List<AppTask>
where you can get the
RecentTaskInfo
with
getTaskInfo
" but i can't figure it out how to use it. Please help me out here in this regard.

private void postNotification(Context ctx, Intent intent) {
try {
if (intent == null) {
Log.d(TAG, "Receiver intent null");
} else {
String action = intent.getAction();
if (action.equals("com.ziza.cy.UPDATE_STATUS")) {

JSONObject json = new JSONObject(intent.getExtras()
.getString("com.parse.Data"));

String type = json.getString("type");

if (type.equals("AlertNotification")) {

String msg = json.getString("header");
String title = "ncy";

ActivityManager am = (ActivityManager) ctx
.getSystemService(Context.ACTIVITY_SERVICE);
List<RunningTaskInfo> taskInfo = am.getRunningTasks(1);
ComponentName componentInfo = taskInfo.get(0).topActivity;

// don't show notification if app is in foreground
if (componentInfo.getPackageName().equalsIgnoreCase(
ctx.getPackageName())) {

// send broadcast receiver
Intent intentBroad = new Intent();
intentBroad.setAction(Constants.sNOTIFICATION);
intentBroad.putExtra("msg", msg);
intentBroad.putExtra("title", title
+ " "
+ taskInfo.get(0).topActivity.getClass()
.getSimpleName());
ctx.sendBroadcast(intentBroad);
} else {
// Activity Not Running
// Generate Notification

Intent intnt = new Intent(ctx, LogInActivity.class);
PendingIntent contentIntent = PendingIntent
.getActivity(ctx, 0, intnt, 0);
intnt.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_NEW_TASK);

NotificationCompat.Builder builder = new NotificationCompat.Builder(
ctx)
.setContentTitle(title)
.setContentText(msg)
.setTicker(msg)
.setSound(
RingtoneManager
.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
.setStyle(
new NotificationCompat.BigTextStyle()
.bigText(msg))
.setAutoCancel(true)
.setSmallIcon(R.drawable.iconed)
.setOnlyAlertOnce(true)
.setDefaults(Notification.DEFAULT_VIBRATE);

Uri alarmSound = RingtoneManager
.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
builder.setSound(alarmSound);
builder.setContentIntent(contentIntent);
NotificationManager notificationManager = (NotificationManager) ctx
.getSystemService(Context.NOTIFICATION_SERVICE);

notificationManager.notify(0, builder.build());

}
}
}
}

} catch (JSONException e) {
Log.d(TAG, "JSONException: " + e.getMessage());
}
}

Answer

This should help you get started

ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.AppTask> tasks = activityManager.getAppTasks();

for (ActivityManager.AppTask task : tasks) {
    Log.d(TAG, "stackId: " + task.getTaskInfo().stackId);
}
