I have made an forum application in android and used phpmyadmin as my database. But when a question gets a new answer the application should show a notification to all users so how can i do it is there a need to use firebase or by just using a webservice!
Firstly, you need to go to the firebase console and create an app. (For this you will need to login into your google account) and follow the steps provided here.
https://firebase.google.com/docs/
Once that is done you will need to add these services to your Manifest.xml file
<service
android:name=".firebase.FirebaseMessagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
<service
android:name=".firebase.FirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
FirebaseInstanceIdService.class
public class FirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String TAG = "FirebaseInstanceIDService";
#Override
public void onTokenRefresh() {
String token = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "OnTokenRefresh callback. Token received : " + token);
}
}
FirebaseMessagingService.class
public class FirebaseMessagingService extends com.google.firebase.messaging.FirebaseMessagingService {
private static final String TAG = "FirebaseMessagingService";
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG,"onMessageReceived.");
showNotification(remoteMessage.getData().get("message"));
}
private void showNotification(String message) {
Intent i = new Intent(this, HomeActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this,0,i,PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
.setAutoCancel(true)
.setContentTitle("Slapr Notification Demo")
.setContentText(message)
.setSmallIcon(R.drawable.common_google_signin_btn_icon_dark)
.setContentIntent(pendingIntent);
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
manager.notify(0,builder.build());
}
}
Now you can get the tokenId in your activity by doing the following
Log.d(TAG, "Recieved token : " + FirebaseInstanceId.getInstance().getToken());
This are the most helpful tutorials that i had found when i started. I hope it helps you.

i am new to android, here is how i am reciving and showing notification, but the thing is everytime i am sending notification from server the code comes to onMessageReceived but not not displaying any notification on Android Phone testing :
public class MyFirebaseMessagingService extends FirebaseMessagingService{
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d("Message Notic", "========================>>>>> >>>>> >>>>> Some message came: " +remoteMessage.getData().get("message"));
showNotification(remoteMessage.getData().get("message"));
}
private void showNotification(String message) {
Intent i = new Intent(this,MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this,0,i,PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
.setAutoCancel(true)
.setContentTitle("FCM Test")
.setContentText(message)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentIntent(pendingIntent);
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
manager.notify(0,builder.build());
}
}
Here i am not able to get the data on two devices i tested :
OnePlus 5 - Android Version (Oreo 8.0.0)
Le Echo - Android Version (6.0.0)
Any issue you can address here will be great! Why i am not seeing any notification.
Thank you!
Add this in your manifest.xml :
<service
android:name=".MyFirebaseMessagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
<service
android:name=".MyFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
MyFirebaseInstanceIDService.java
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String TAG = "MyFirebaseIIDService";
#Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "Refreshed token: " + refreshedToken);
sendRegistrationToServer(refreshedToken);
}
private void sendRegistrationToServer(String token) {
// TODO: Implement this method to send token to your app server.
}
}
MyFirebaseMessagingService.java
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG, "From: " + remoteMessage.getFrom());
}
}
For Android O you must specify notification channel for your notification.
check the documentation
https://developer.android.com/guide/topics/ui/notifiers/notifications.html#ManageChannels
I am trying to send push messages from Firebase to my Android application:
Both of the MyFirebaseInstanceIDService and MyFirebaseMessagingService class are inside the service package of my main package. Below is my folder structure
So in my AndroidManifest they are represented as
<service
android:name=".services.MyFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
<service
android:name=".services.MyFirebaseMessagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
MyFirebaseInstanceIDService class:
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String TAG = MyFirebaseInstanceIDService.class.getSimpleName();
#Override
public void onTokenRefresh() {
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "-------- refreshedToken: " + refreshedToken);
//TODO: send the token to the node server to store it in mysql
}
}
MyFirebaseMessagingService class:
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = MyFirebaseMessagingService.class.getSimpleName();
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG, "From: " + remoteMessage.getFrom());
if(remoteMessage.getData().size() > 0) {
Log.d(TAG, "Message data payload: " + remoteMessage.getData());
}
if(remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
}
Intent intent = new Intent(this, SplashActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, "280887");
notificationBuilder.setContentTitle("FCM Notification");
notificationBuilder.setContentText(remoteMessage.getNotification().getBody());
notificationBuilder.setAutoCancel(true);
notificationBuilder.setSmallIcon(R.mipmap.ic_launcher_round);
notificationBuilder.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}
}
The issue is when I run my app I do not get the registration token. All the examples I have seen online or youtube, they have all their files under single package. But in my case I got sub-packages for each type of file. Is this is issue?
Also, in MyFirebaseInstanceIDService when I store the token in shared preference and retrieve it in HomeActivity the token is null.
***************** EDIT*****************
My Logcat gives Tag Manager is not found and thus will not be used message. It is not showing any tags V, I, D non of them
You need to add your project in Firebase and then download a file named "google.json" and insert it inside your project. otherwise the authentication will fail and you won't receive any token.
Also you won't receive any new token until it changes.
on the other hand, Google usually doesn't send pushes immediately specially on Debug mode.
Send Registration To Server
Make sure you have added your project to Firebase and downloaded the correct google-services.json file and placed it in the Apps folder
Use the code similar to the one below and Register the token to the Server
package com.dev.gideon.services;
import [LOCATION-TO-YOUR-SHAREDPREF].SharedPref;
import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;
public class FcmInstanceIDService extends FirebaseInstanceIdService {
private SharedPref sharedPref;
#Override
public void onTokenRefresh() {
sharedPref = new SharedPref(this);
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
sendRegistrationToServer(refreshedToken);
}
private void sendRegistrationToServer(String token) {
sharedPref.setFcmRegId(token);
sharedPref.setOpenAppCounter(SharedPref.MAX_OPEN_COUNTER);
}
}
Try if it Helps!!!
I can receive push notification when my app is in foreground or background
I added FcmBroadcastReceiver extends WakefulBroadcastReceiver in order to get push
when I close my application.
But I continue without receiving notifications when the app is closed.
Thanks for your help.

The issue that I can see in your code is that you are implementing the FireBase push notification but you are trying to implement that in a way that was used to implement GCM. You don't need to set any Broadcast Receivers, Firebase is doing that by itself. You just have to run "FirebaseMessagingService". The services looks like this:
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "FCM Service";
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// TODO: Handle FCM messages here.
// If the application is in the foreground handle both data and notification messages here.
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated.
Log.d(TAG, "From: " + remoteMessage.getFrom());
Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
}
}
As you can see it has it's own "onMessageReceived" method that takes care of Broadcast Receiver's functionality.
Check this tutorial, it will help you to understand:
https://www.codementor.io/flame3/send-push-notifications-to-android-with-firebase-du10860kb
Note: If you want your app to work in each situation even app is in background, foreground or even closed then you need to send some data through payload in your notification.then it will work for all conditions. To do that you need your own server, Firebase doesn't facilitate for that.
I try this code for GCM push notification.
In this for send notification I use this. But it shows the message like Cool! Message sent successfully check your device... But My device does not receive Notification.
Try Firebase, here is the documentation of Push-Notification https://firebase.google.com/docs/cloud-messaging/ or you can check this tutorial https://www.simplifiedcoding.net/android-push-notification-tutorial-using-firebase/
You should use FCM. See
1) Add this line to build.gradle: dependencies {
compile 'com.google.firebase:firebase-messaging:9.8.0'}
2) Add this service to manifest.
<service
android:name=".MyFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
3) Add this class to your project. I suggest to you to save your FCM Token:
public class MyInstanceIDListenerService extends FirebaseInstanceIdService {
#Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d("FirebaseService", "Refreshed token: " + refreshedToken);
SharedPreferences sharedPref = getSharedPreferences("YOUR_SETTING_NAME", Context.MODE_PRIVATE);
//There are optional steps
SharedPreferences.Editor editor = sharedPref.edit();
editor.putString("token", refreshedToken);
//notify the token update
editor.putBoolean("tokenUpdate",true);
editor.commit();
//You can send this token to your server (if you have)
sendServer(refreshedToken)
}
}
4) Now register your app to https://console.firebase.google.com/. This will generate a JSON file that's you must put inside app folders.
5) For generate FCM message you have 2 possibility:
5.1) Use the default Firebase Console: https://console.firebase.google.com/project/fantamanager-2017/notification/compose
5.2) Built your server app (If you want, i can send to you my Php Server Code)
6) Add this Service to your Manifest.xml
<service android:name="FcmBroadcastReceiver">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
And create a class that can intercept the push:
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final ID_NOTIFICATION = ...
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
String from,data;
from=remoteMessage.getFrom());
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
data=remoteMessage.getNotification().getBody());
}
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated. See sendNotification method below.
sendNotification(data);
}
private void sendNotification(String messageBody) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_stat_ic_notification)
.setContentTitle("FCM Message")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(ID_NOTIFICATION, notificationBuilder.build());
}
}
Or, if you have a custom service, change the body of onMessageReceived function with this:
Map data = message.getData();
if (data.containsKey(YOUR_DATA_FIELD_1)) {
String field1= data.get(YOUR_DATA_FIELD_1).toString();
String field2= data.get(YOUR_DATA_FIELD_2).toString();
....
sendNotification(field1,field2...);
return;
}
Did you try a part or whole code ? Coz last I saw , new applications for gcm are closed. Only FCM is available. So you need to register as they say , implement the json file in app and proceed. If you already had a project which implemented gcm and you tried part of this code , then please check if the key is proper and you have not copied they key from this project or something . or maybe some meta data from manifest file is missing.
I've got Firebase building without any warnings using Eclipse (see related: Unable to find obfuscated Firebase class in Eclipse)
I try to send a test notification, however I'm not getting anything. I'm using a library project as well. This is my code:
AndroidManifest.xml
<application />
...
<!-- ==================================
FIREBASE
=================================== -->
<service
android:name=".MyFirebaseMessagingService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<service
android:name=".MyFirebaseInstanceIdService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
....
</application>
These files are practically straight from the samples:
public class MyFirebaseMessagingService extends FirebaseMessagingService {
public static final String PUSH_NOTIFICATION_TEXT = "pushnotificationtext";
private static final String TAG = "Firebase";
public static final int NOTIFICATION_ID = 1;
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// Handle data payload of FCM messages.
String messageId = remoteMessage.getMessageId();
RemoteMessage.Notification notification = remoteMessage.getNotification();
Map<String, String> data = remoteMessage.getData();
Log.d(TAG, "FCM Message Id: " + messageId);
Log.d(TAG, "FCM Notification Message: " + notification);
Log.d(TAG, "FCM Data Message: " + data);
sendNotification(this, notification.toString());
}
// Put the GCM message into a notification and post it.
private void sendNotification(Context context, String message) {
NotificationManager mNotificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
final Intent intent = new Intent(context, Splash.class);
//intent.putExtras(bundle);
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
//Save push notification message to show when app starts
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(context);
sp.edit().putString(PUSH_NOTIFICATION_TEXT, message).commit();
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_ONE_SHOT);
final NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
.setAutoCancel(true)
.setVibrate(new long[] { 0, 500, 200, 500, 200, 500 })
.setContentIntent(contentIntent)
.setContentTitle(context.getString(R.string.app_name))
.setSmallIcon(R.drawable.ic_launcher)
.setStyle(new NotificationCompat.BigTextStyle().bigText(message))
.setContentText(message)
.setWhen(System.currentTimeMillis()).setOngoing(false);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}
}
Other class:
public class MyFirebaseInstanceIdService extends FirebaseInstanceIdService {
private static final String TAG = "Firebase";
private static final String FRIENDLY_ENGAGE_TOPIC = "friendly_engage";
/**
* The Application's current Instance ID token is no longer valid
* and thus a new one must be requested.
*/
#Override
public void onTokenRefresh() {
// If you need to handle the generation of a token, initially or
// after a refresh this is where you should do that.
String token = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "FCM Token: " + token);
// Once a token is generated, we subscribe to topic.
FirebaseMessaging.getInstance().subscribeToTopic(FRIENDLY_ENGAGE_TOPIC);
}
}
I send a message via the Firebase console targeting the package name with no luck. I'm uncertain what I should do to get this to work. Do I need to use the google-services.json file in some way?
Thanks
I don't use Eclipse and am not able to verify that these steps work. I hope they will get you started on the right path.
The Firebase framework is initialized by FirebaseInitProvider. You don't need to implement or subclass it. Just declare it in your manifest.
<provider
android:authorities="${applicationId}.firebaseinitprovider"
android:name="com.google.firebase.provider.FirebaseInitProvider"
android:exported="false"
android:initOrder="100" />
FirebaseInitProvider expects to find string resources that contain the configuration values for the project. In an app built with Android Studio and the Google Services Gradle Plugin, the resource values are created from the google-services.json file. Because you are not using AS and the plugin, you will need to define these resources in your res folder. The values can be found in your Project Settings at the Firebase Console or in the google-service.json file. Because you are only interested in messaging, some values may not be needed. To be safe, define them all initially.
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="default_web_client_id" translatable="false">8888888888888-ooqodhln4cjj4qst7b4sadfiousdf7.apps.googleusercontent.com</string>
<string name="firebase_database_url" translatable="false">https://project-888888888888888.firebaseio.com</string>
<string name="gcm_defaultSenderId" translatable="false">888888888888</string>
<string name="google_api_key" translatable="false">AIzaSyB0Bhr1sfsydfsdfnwelhkOYifak_Go2xU</string>
<string name="google_app_id" translatable="false">1:888888888888:android:526f9740dfg987sdfg</string>
<string name="google_crash_reporting_api_key" translatable="false">AIzaSyDkG-g8hH7T4TV7Rrsdfgiopudfmn234897</string>
<string name="google_storage_bucket" translatable="false">project-8888888888888888888888.appspot.com</string>
</resources>
You can confirm that the initialization succeeded by putting this code in the onCreate() method of your main activity:
FirebaseOptions opts = FirebaseApp.getInstance().getOptions();
Log.i(TAG, "onStart: ID=" + opts.getApplicationId());
Log.i(TAG, "onStart: SenderId=" + opts.getGcmSenderId());
Log.i(TAG, "onStart: Key=" + opts.getApiKey());
If valid results are logged, it indicates the default FirebaseApp has been initialized, and you should be able to receive messages.
