How to create notification inside an activity in android?

I have a task in which I have to show Notification for an incoming message inside an activity using BroadcastReceiver with the address and content on the SMS. Now I have to click in order to insert the values in sms in database. When the task is finished i want it to clear from the activity. Is it possible to create notification for incoming sms inside an Activity?

You can Try This no generate your own Notification.
#SuppressWarnings("deprecation")
private static void generateNotification(Context context) {
int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, "New Contact Added",
when);
String title = context.getString(R.string.app_name);
Intent notificationIntent = new Intent(context, MainActivity.class);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
int iUniqueId = (int) (System.currentTimeMillis() & 0xfffffff);
PendingIntent intent = PendingIntent.getActivity(context, iUniqueId,
notificationIntent, 0);
notification.setLatestEventInfo(context, title, "New", intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
// Play default notification sound
notification.defaults |= Notification.DEFAULT_SOUND;
// Vibrate if vibrate is enabled
notification.defaults |= Notification.DEFAULT_VIBRATE;
notificationManager.notify(2, notification);
}

Perform Action On Button Click in Custom Notification : Android

I am trying to perform some action like pause music , play music on button click of a custom notification in android.
Currently I am doing it in this way ,
int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
Notification notification = new Notification(icon, "Custom Notification", when);
NotificationManager mNotificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.layout);
contentView.setTextViewText(R.id.textView1, "Custom notification");
contentView.setOnClickPendingIntent(R.id.button1, pIntent);
notification.contentView = contentView;
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notification.contentIntent = contentIntent;
notification.flags |= Notification.FLAG_NO_CLEAR; //Do not clear the notification
notification.defaults |= Notification.DEFAULT_LIGHTS; // LED
notification.defaults |= Notification.DEFAULT_VIBRATE; //Vibration
notification.defaults |= Notification.DEFAULT_SOUND; // Sound
mNotificationManager.notify(1, notification);
But this one takes me to another activity.
Is there anyway to implement notification action on the same activity.
for example.. let's say i raise a notifcation, and when the user press on it, then instead of take me to some activity, it invoke some regular method in my current activity/service

First of All assign a intent to your buttons:
RemoteViews contentView = new RemoteViews(context.getPackageName(), R.layout.player_notify_layout);
Intent buttonsIntent = new Intent(context, NotifyActivityHandler.class);
buttonsIntent.putExtra("do_action", "play");
contentView.setOnClickPendingIntent(R.id.imgPlayPause, PendingIntent.getActivity(context, 0, buttonsIntent, 0));
Then create an activity to handle every action that occurred by notification:
public class NotifyActivityHandler extends Activity {
public static final String PERFORM_NOTIFICATION_BUTTON = "perform_notification_button";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String action = (String) getIntent().getExtras().get("do_action");
if (action != null) {
if (action.equals("play")) {
// for example play a music
} else if (action.equals("close")) {
// close current notification
}
}
finish();
}
}
Finally, you should define activity in AndroidManifest.xml. Also you can check this link.

Make Notification cleared by user or once clicked

I have a service that may show a notification, the problem is once the notification is set, it doesn't clear neither when clicked, nor when swiped on. I am using the flag Notification.FLAG_AUTO_CANCEL but it doesn't seem to do anything..
private NotificationManager nm;
nm = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
private final int NOTIFY_ID = 1;
private void showNotification(String date, String name) {
try{
CharSequence text = "You have new Event";
Notification notification = new Notification(R.drawable.small_icon, text, System.currentTimeMillis());
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, viewEvents.class).putExtra("date", date), 0);
notification.setLatestEventInfo(this, name, "Date: "+date, contentIntent);
notification.defaults |= Notification.DEFAULT_SOUND;
notification.defaults |= Notification.DEFAULT_VIBRATE;
notification.defaults |= Notification.DEFAULT_LIGHTS;
notification.defaults |= Notification.FLAG_AUTO_CANCEL;
nm.notify(NOTIFY_ID, notification);
}catch(Exception e){
Log.i("Notification",e.toString());
}
}
So what am I doing wrong?

Try using Notification.Builder or NotificationCompat.Builder instead of rolling the Notification manually.
Among other things, this would prevent the bug in your code, where you are applying FLAG_AUTO_CANCEL to defaults rather than flags.

Notification.FLAG_AUTO_CANCEL is commented out in your code.
But in case it isn't then flag Notification.DEFAULT_LIGHTS should be setted in notification.defaults not in notification.flags

I use this code to show/hide notifications:
private Handler handler = new Handler();
private Runnable task = new Runnable() {
#Override
public void run() {
NotificationManager manager = (NotificationManager) contesto.getSystemService(Context.NOTIFICATION_SERVICE);
Intent launchIntent = new Intent(contesto.getApplicationContext(), SearchHistory.class);
PendingIntent contentIntent = PendingIntent.getActivity(contesto.getApplicationContext(), 0, launchIntent, 0);
//Create notification with the time it was fired
NotificationCompat.Builder builder = new NotificationCompat.Builder(contesto);
builder.setSmallIcon(R.drawable.ic_launcher).setTicker("MESSAGE HERE!").setWhen(System.currentTimeMillis()).setAutoCancel(true).setDefaults(Notification.DEFAULT_SOUND).setContentTitle("TITLE").setContentText("MESSAGE").setContentIntent(contentIntent);
Notification note = builder.build();
manager.notify(100, note);
}
};
And to invoke just put:
handler.post(task);

Android notification click

a notification pops up when I get a new task. On click on that notification, it goes to TestExList.java activity.
private void createNewTaskNotification(String s, String id) {
CharSequence title = "TASK";
CharSequence message = s;
notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.checkyes, s,
System.currentTimeMillis());
notification.flags = Notification.FLAG_AUTO_CANCEL;
notification.defaults |= Notification.DEFAULT_SOUND;
notification.defaults |= Notification.DEFAULT_VIBRATE;
Intent notificationIntent = new Intent(context, TestExList.class);
notificationIntent.putExtra("EmpID", Functions.getLoginEmpID(context));
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP );
PendingIntent pendingIntent = PendingIntent.getActivity(context,
Integer.parseInt(id), notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
notification.setLatestEventInfo(context, title, message, pendingIntent);
notificationManager.notify(Integer.parseInt(id), notification);
}
The way it's working is, if i am on another screen, click on notification takes me to TestExList.java.
If i am on the same screen(TestExList.java), it is NOT loading that page aagain. I would like to refresh that page so that I can see my new task on that page.
what am I doing wrong ?

remove this line
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP );
this line pops up the activity from activity stack if activity exists, otherwise creates a new instance of the activity, hope this helps.
