Sending Notifications To Your Users Just With Phone ! Using Firebase

For any Android developer, sending notifications or messages is an important thing to notify the user and get his attention, therefore most developers use firebase (cloud service) as a “third part” to get this feature. However, you can’t just send your message or notification with your mobile phone, instead you’re gonna need a computer to get access to the cloud service website,and do your job.

But hold on a minute, what should I do ?

Great question ! here’s your answer : You can use an app that’s gonna help you sending your notifications at any time, without having to use a computer or a laptop, it’s called “Push Notification firebase”.

Download from here Assuming you have the application now, there’s a couple of steps that need to be executed before you start using it

1-subscribe all user in same topic named “any”

make all your users subscribing to topic named “Any”, just like this code below (In JAVA):

SharedPreferences shared_Save = getSharedPreferences("UserData", Context.MODE_PRIVATE);
if (!shared_Save.getBoolean("NOTIFICQTION",false)){
FirebaseMessaging.getInstance().subscribeToTopic("any").addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()){
shared_Save.edit().putBoolean("NOTIFICQTION",true).apply();
}
}
});
}

2 add your Server key to app

Add your server key to the “Push Notification” app, you can find the server key of your firebase project by going to

Project settings -> cloud Messaging -> server key

3- One last thing, don’t forget to add MyFirebaseMessagingService class to your project And that’s it ! you’re good to go .
