Android Firebase Messaging

Android Firebase Messaging

Step 1. Create New Android Project

Step 2. Open 2nd build.gradle file and paste the dependency

compile 'com.google.firebase:firebase-core:11.8.0'
compile 'com.google.firebase:firebase-messaging:11.8.0'
//and in bottom put this line

apply plugin: 'com.google.gms.google-services'

Now its look like this

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.sswebtricks.sanjeev.firebasetutorial"
        minSdkVersion 16
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

        }
    }
}


dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    compile 'com.google.firebase:firebase-core:11.8.0'
    compile 'com.google.firebase:firebase-messaging:11.8.0'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}
apply plugin: 'com.google.gms.google-services'

Step 2a. Open 1st build.gradle file and paste the classpath

        classpath 'com.google.gms:google-services:3.1.1' // google-services plugin

Now file look like this

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        classpath 'com.google.gms:google-services:3.1.1' // google-services plugin
        

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Step 3. Open AndroidManifest.xml file and paste the service code and notification color for firebase inside application Tag 

<meta-data android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="@drawable/marker" />
<meta-data
android:name="com.google.firebase.messaging.default_notification_color"
android:resource="@color/colorAccent" />
<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>

Step 4. Create MyFirebaseMessagingService.class which is firebase messaging service which is responsible for receiving our firebase notification

package com.sswebtricks.sanjeev.firebasetutorial;

import android.app.Service;


import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.media.RingtoneManager;
import android.net.Uri;
import android.support.v4.app.NotificationCompat;
import android.util.Log;


import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private static final String TAG = "MyFirebaseMsgService";

    @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());
        }
        sendNotification(remoteMessage.getNotification().getBody());
    }
    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);

        String channelId = getString(R.string.project_id);
        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder =
                new NotificationCompat.Builder(this, channelId)
                        .setSmallIcon(R.drawable.marker)
                        .setContentTitle("FCM Message")
                        .setContentText(messageBody)
                        .setAutoCancel(true)
                        .setSound(defaultSoundUri)
                        .setContentIntent(pendingIntent);

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
    }
}

Step 5. Create MyFirebaseInstanceIDService.class which is firebase messaging service for generating our firebase tokens

package com.sswebtricks.sanjeev.firebasetutorial;

import android.app.Service;

/**
 * Created by sanjeev on 31/1/18.
 */

import android.util.Log;

import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;


public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {

    private static final String TAG = "MyFirebaseIIDService";

    @Override
    public void onTokenRefresh() {
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
        Log.d(TAG, "Refreshed token: " + refreshedToken);
        sendRegistrationToServer(refreshedToken);
    }

    private void sendRegistrationToServer(String token) {

    }

}

Step 6. Create New Project in https://console.firebase.google.com/
Add android to your project and download google-services.json which you got when generating your project.

Step 7. Then from right nav click on Android->then Select Project and Paste the google-services.json in app directory

Step 8. Now we are Ready to check our messages Go to Firebase Console then Grow->Notifcation and send your test Message

Step 9. Then Check in Your App
