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))

Multiple push notifications on android with wrong icon size

Let me preface this post with the fact that I am new to the android programming.
When I issue a notification, the phone shows two notifications for the same thing. The only difference is, the icons look different and they do different things. The first will do nothing when you select it. The other opens the app to the correct page.
I used to only get one notification until I edited this method. I'm not sure what I did but perhaps someone could tell me why this sends 2 and how to fix it?
The other question I have is that on both notifications on the phone, the icon is zoomed in (or too big). How do you make the push notification icon the correct size?
Here is my method
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, FriendGroupActivity.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);
}

Try this :
private void generateNotification(Context context, String message) {
int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
String appname = context.getResources().getString(R.string.app_name);
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
int currentapiVersion = android.os.Build.VERSION.SDK_INT;
Notification notification;
PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
new Intent(context, myactivity.class), 0);
// To support 2.3 os, we use "Notification" class and 3.0+ os will use
// "NotificationCompat.Builder" class.
if (currentapiVersion < android.os.Build.VERSION_CODES.HONEYCOMB) {
notification = new Notification(icon, message, 0);
notification.setLatestEventInfo(context, appname, message,
contentIntent);
notification.flags = Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, notification);
} else {
NotificationCompat.Builder builder = new NotificationCompat.Builder(
context);
notification = builder.setContentIntent(contentIntent)
.setSmallIcon(icon).setTicker(appname).setWhen(0)
.setAutoCancel(true).setContentTitle(appname)
.setContentText(message).build();
notificationManager.notify(0 , notification);
}
}
Hope this helps.This works for me.

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"

Notification not making sound or vibration?

I am making a program and I want the app to make a notification. When the notification goes off then only the ticker text is displayed. No sound or vibration or light is accompanied with it.
Here is an example of my code:
int icon = R.drawable.icon;
NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
Context context = getApplicationContext();
CharSequence contentTitle = "My notification";
CharSequence contentText = "Countdown Complete!";
Intent intent = new Intent();
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
Notification notification = new Notification(icon, myCountDown.getName() + " is completed!", System.currentTimeMillis());
long[] vibrate = {0,100,200,300};
notification.vibrate = vibrate;
notification.defaults |= Notification.DEFAULT_LIGHTS;
notification.defaults |= Notification.DEFAULT_SOUND;
notification.setLatestEventInfo(context, contentTitle, contentText, pendingIntent);
notificationManager.notify(myCountDown.getId(), notification);

To add notification light you need to add this(notice the .flags, not .defaults):
notification.flags |= Notification.FLAG_SHOW_LIGHTS;
notification.ledARGB=0xffffffff; //color, in this case, white
notification.ledOnMS=1000; //light on in milliseconds
notification.ledOffMS=4000; //light off in milliseconds
For default sound:
notification.defaults |= Notification.DEFAULT_SOUND;
For default vibration pattern:
notification.defaults |= Notification.DEFAULT_VIBRATE;
For vibration, as Dean Thomas mentioned, you'll need a permission <uses-permission android:name="android.permission.VIBRATE"/>

To make the LED work, you need to tell it what to do.
notification.ledOnMS = 1000; //Be on for a second
notification.ledOffMS = 1000; //Be off for a second
notification.ledARGB = Color.GREEN; //What colour should the LED be?
To make the vibrate work, you need permission added to your Manifest
<uses-permission android:name="android.permission.VIBRATE"/>

Did you ensure the device is not muted and actually has a notification sound picked by the user (also not silent)?
Another thing to try would be:
[Note obj].sound = value
[Note obj].LEDARGB = value
[Note obj].vibrate = value

I find there is a setDefaults method in NotificationCompat.Builder , and it provides you for adjusting notification preferences.
Here is an example:
NotificationManager notificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationCompat.Builder builder =
new NotificationCompat.Builder(this);
builder.setSmallIcon(R.drawable.taiwanpic)
.setWhen(System.currentTimeMillis())
.setContentTitle("AAAAA")
.setContentText("BBBBB")
.setSubText("CCCCC")
.setContentInfo("DDDDD")
.setTicker("EEEEE")
.setDefaults(Notification.DEFAULT_ALL);
int pid = android.os.Process.myPid();
notificationManager.notify(pid, builder.build());
If you don't use all default values, you can also try DEFAULT_SOUND, DEFAULT_VIBRATE,DEFAULT_LIGHTS as you want.
