Android How to show alert on another app

Hi I want to show alert after click on my notification. Here is code:
#SuppressWarnings("deprecation")
private void Notify(String notificationTitle, String notificationMessage) {
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon_stat, "Powiadomionko", System.currentTimeMillis());
notification.ledARGB = Color.CYAN;//0xFFff0000;
notification.ledOnMS = 800;
notification.ledOffMS = 2400;
notification.vibrate = new long[]{100, 120, 100, 120};
Intent notificationIntent = new Intent(this, TerminarzActivity.class);
notification.flags = Notification.FLAG_SHOW_LIGHTS | Notification.FLAG_AUTO_CANCEL | Notification.DEFAULT_VIBRATE;
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
notification.setLatestEventInfo(Serwis_updateTERM.this, notificationTitle, notificationMessage, pendingIntent);
notificationManager.notify(1, notification);
}
And I want to show Alert on anything not on my Activity after click. Anyone know how to do this ?
I know i must add
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
but nothing else..

Check out the creation of this notification (taken from Geofence sample). This code creates a notification and if you touch it it launches your MainActivity.
// Create an explicit content Intent that starts the main Activity
Intent notificationIntent = new Intent(getApplicationContext(), MainActivity.class);
// Construct a task stack
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the main Activity to the task stack as the parent
stackBuilder.addParentStack(MainActivity.class);
// Push the content Intent onto the stack
stackBuilder.addNextIntent(notificationIntent);
// Get a PendingIntent containing the entire back stack
PendingIntent notificationPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
// Get a notification builder that's compatible with platform versions
// >= 4
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
// Set the notification contents
builder.setSmallIcon(R.drawable.ic_folder)
.setContentTitle(getString(R.string.geofence_transition_notification_title, transitionType, ids))
.setContentText(getString(R.string.geofence_transition_notification_text))
.setContentIntent(notificationPendingIntent);
// Get an instance of the Notification manager
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// Issue the notification
mNotificationManager.notify(0, builder.build());
This code might help you, but still it depends what do you mean by "alert".

How can I open activity when notification is touched?

I am building a notification for my Music Player, so it displays what music is playing.
But I want to add a function where, when I touch it. It opens my layout player.xml. Which is deployed through the MainActivity.class.
I have researched on Notifications on developer.android.com and found a way to deploy and activity upon clicking the notification. But it did't work.
Here is my current code -
Notification.Builder builder = new Notification.Builder(getApplicationContext());
builder.setContentTitle(songsList.get(songIndex).get("songTitle"));
builder.setContentText("NexPlay™");
builder.setTicker(songsList.get(songIndex).get("songTitle"));
builder.setSmallIcon(R.drawable.ic_launcher);
builder.setSmallIcon(R.drawable.play_default);
builder.setAutoCancel(true);
builder.setPriority(0);
builder.setOngoing(true);
Notification notification = builder.build();
NotificationManager notificationManger =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManger.notify(01, notification);
Thanks to everyone for answering!
I added
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, new Intent(this, NotificationToPlayer.class), 0);
builder.setContentIntent(pendingIntent);
to my notifications and it worked great !

Try this
private void showNotification() {
// In this sample, we'll use the same text for the ticker and the expanded notification
CharSequence text = getText(R.string.service_started);
// Set the icon, scrolling text and timestamp
Notification notification = new Notification(R.drawable.android, text,
System.currentTimeMillis());
// The PendingIntent to launch our activity if the user selects this notification
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
new Intent(this, ServiceLauncher.class), 0);
// Set the info for the views that show in the notification panel.
notification.setLatestEventInfo(this, getText(R.string.service_label),
text, contentIntent);
notification.defaults |= Notification.DEFAULT_SOUND;
// Send the notification.
// We use a layout id because it is a unique number. We use it later to cancel.
nm.notify(R.string.service_started, notification);
}
Hope this will solve your problem

You need to add intent on ur code:-
int icon = R.drawable.app_launcher;
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message.split(":::")[1], when);
String title = context.getString(R.string.app_name);
Intent notificationIntent = null;
notificationIntent = new Intent(context, MessageDetail.class);
PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
notification.setLatestEventInfo(context, title, message.split(":::")[1], 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(0, notification);

You'll also want to add an intent. Something like:
Intent actIntent = new Intent(this, do MyActivity.class);
Then in your builder:
.setContentIntent(PendingIntent.getActivity(MyActivity, 131314, actIntent,
PendingIntent.FLAG_UPDATE_CURRENT))

Use notification ID to change logo & text

I'd like to know how applications like Facebook change their notification title & logo depending on the content.
For example, in Facebook, if you get tagged you get another title & another logo.
I assume it should be possible with notify to create a unique notification.
Though I can't find any clear examples for this.
My GenerateNotification:
private static void generateNotification(Context context, String message, String url) {
int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
String title = context.getString(R.string.app_name);
Intent notificationIntent = new Intent(context, ShowChange.class);
notificationIntent.putExtra ("url",url);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent =
PendingIntent.getActivity(context, 0, notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
// Play default notification sound
notification.defaults |= Notification.DEFAULT_SOUND;
//notification.sound = Uri.parse("android.resource://" + context.getPackageName() + "your_sound_file_name.mp3");
// Vibrate if vibrate is enabled
notification.defaults |= Notification.DEFAULT_VIBRATE;
notificationManager.notify(0, notification);
}

It should be something like this:(this is basically your code with some modifications)
public static void generateNotification(Context context, String message, String url,int icon_from_drawable) {
int icon = icon_from_drawable;
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
String title = context.getString(R.string.app_name);
Intent notificationIntent = new Intent(context, ShowChange.class);
notificationIntent.putExtra ("url",url);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent =
PendingIntent.getActivity(context, 0, notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
// Play default notification sound
notification.defaults |= Notification.DEFAULT_SOUND;
//notification.sound = Uri.parse("android.resource://" + context.getPackageName() + "your_sound_file_name.mp3");
// Vibrate if vibrate is enabled
notification.defaults |= Notification.DEFAULT_VIBRATE;
notificationManager.notify(0, notification);
}
If you targeting your app for API LEVEL>=11, then use Notification.Builder
refer here : http://developer.android.com/reference/android/app/Notification.Builder.html
One more point the above code will keep updating the same notification object because the notify method of notification manager is taking always the same id i.e 0, so the same object of notification will be updated.

Push Notification received, but no message

I am developing an android app, which needs to receive the push notification.
The push notification is received but there is no message, just when I click on launcher icon in notification it launched app, but no message is received.
I am here handling only the receiving notification part, the notification is sent by some other guy from server and he is using VB.net for that, cant check his code. But I can post mine.
My onMessage:
protected void onMessage(Context context, Intent intent) {
Log.i(TAG, "Received message");
String message = intent.getExtras().getString("price");
generateNotification(context, message);
}
My generateNotification
private static void generateNotification(Context context, String message) {
int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
String title = context.getString(R.string.app_name);
Intent notificationIntent = new Intent(context, CoursesMainActivity.class);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent =
PendingIntent.getActivity(context, 0, notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, 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(0, notification);
}
Please help with this, if someone wants to VB.net code for sending message I can provide that too.
Thanks,
Asmi

I resolved it as the other person(sending the push notification) was not sending it as "price", but as "message"

Android - GCM push notifications not appearing in notifications list

I'm working on my first Android app to use the Google Cloud Messaging (GCM) service for push notifications. I've got to the point where I can successfully send a message from my server application, and log the content of the message in the onMessage event within my GCMIntentService class on the client app. However I don't see any visual indication on the device that a message was received. I was expecting the message to appear in the pull-down notifications list on the phone, as it does on the iPhone. Does this have to be coded manually? Also is there a common method for displaying the message regardless of which activity is currently active, and if the app is idle in the background? Any help appreciated.

This code will generate a notification in the android system bar at the top of the screen. This code will create a new intent that will direct the user to a "Home.class" after clicking on the notification in the top bar. If you would like it to do something specific based on the current activity you could send broadcast requests from the GCMIntentService to your other activities.
Intent notificationIntent=new Intent(context, Home.class);
generateNotification(context, message, notificationIntent);
private static void generateNotification(Context context, String message, Intent notificationIntent) {
int icon = R.drawable.icon;
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
String title = context.getString(R.string.app_name);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent =PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, notification);
}
Note that this example uses resources in R.drawable and R.String that will need to be present to work but it should give you the idea. See this for more information about status notifications http://developer.android.com/guide/topics/ui/notifiers/index.html and this about broadcast recievers. http://developer.android.com/reference/android/content/BroadcastReceiver.html

If you are using GcmListenerService you can use this code, add to your onMessageReceived the sendNotification()
#Override
public void onMessageReceived(String from, Bundle data) {
String message = data.getString("message");
sendNotification(message);
}
private void sendNotification(String message) {
Intent intent = new Intent(this, YOURCLASS.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_park_notification)
.setContentTitle("Ppillo Message")
.setContentText(message)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
