How to set the icon of the app in Device's Status Bar and do notification process? Here it is how to do it:

public static void notifyIcon(Context context){

NotificationManager notifier = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

Notification notification = new Notification(R.drawable.your_app_notification, "", System.currentTimeMillis());

/**

*Setting these flags will stop clearing your icon

*from the status bar if the user does clear all 

*notifications.

*/

    notification.flags |= Notification.FLAG_NO_CLEAR | Notification.FLAG_ONGOING_EVENT;

    RemoteViews contentView = new RemoteViews(context.getPackageName(), R.layout.custom_notification_layout);

    notification.contentView = contentView;

   

//If you want to open any activity on the click of the icon.

    Intent notificationIntent = new Intent(context, YourActivity.class);

    PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);

    notification.contentIntent = contentIntent;

   

    notification.setLatestEventInfo(context, "title", null, contentIntent);

    notifier.notify(1, notification);

//To cancel the icon ...

    notifier.cancel(1);

}

Here is custom_notification_layout.xml

<?xml version = "1.0" encoding = "utf-8"?>

<LinearLayout

    xmlns:android="http://schemas.android.com/apk/res/android"

    android:orientation="horizontal"
