# Android {% hint style="danger" %} **This generation of SDK is deprecated and is no longer supported.**\ Information about the [current version can be found here](/integration/integration-of-sdk-v2/push-notifications/android.md). {% endhint %} Push Notifications on Android are sent with the help of the FCM service. To work with it, two keys are required: a client and server key. If you have a project, move on to the second part of this article. ## Creating a project in Firebase Add a new project to the [Firebase console](https://console.firebase.google.com/). ![](https://www.devtodev.com/upload/images/android_push_doc1.png) Fill in the name and country of your project. ![](https://www.devtodev.com/upload/images/android_push_doc2.png) Congratulations, the project has been created! Now you need to indicate the package name of your Android app. ![](https://www.devtodev.com/upload/images/android_push_doc4.png) ![](https://www.devtodev.com/upload/images/%D0%A1%D0%BD%D0%B8%D0%BC%D0%BE%D0%BA%20%D1%8D%D0%BA%D1%80%D0%B0%D0%BD%D0%B0%202018-09-25%20%D0%B2%2013.44.45.png)\ After a successful registration in Firebase, you can receive your keys that you will use in devtodev. ## Obtaining the necessary keys Go to the settings of your Android project. ![](https://www.devtodev.com/upload/images/android_push_doc7.png) Remember or copy Server key and Sender ID from the Cloud Messaging tab. You will need them to integrate push notifications and create push campaigns. ![](https://www.devtodev.com/upload/images/android_push_doc8.png) ## Implementation in the app Download the generated by google-service.json file and add it to the project. The Google services plugin for [Gradle](https://gradle.org/) loads the google-services.json file that you just downloaded. Modify your build.gradle files to use the plugin. 1. Project-level build.gradle (\/build.gradle): ``` buildscript { dependencies { // Add this line classpath 'com.google.gms:google-services:4.3.3' } } ``` 2. App-level build.gradle (\/\/build.gradle): ``` dependencies { ... implementation 'com.devtodev:android:1.14.5' implementation 'com.google.android.gms:play-services-base:17.1.0' implementation 'com.google.firebase:firebase-core:17.2.3' implementation 'com.google.firebase:firebase-messaging:20.1.0' } // Add to the bottom of the file apply plugin: 'com.google.gms.google-services' ``` 3. Finally, press "Sync now" in the bar that appears in the IDE: \ ![](https://www.gstatic.com/mobilesdk/160330_mobilesdk/images/android_studio_gradle_changed_butterbar@2x.png) 4. In Activity (where the SDK initializes) add the push notifications initialization and the listener of push notifications processing. ``` public class MainActivity extends AppCompatActivity implements PushListener { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); DevToDevPushManager.setPushListener(this); DevToDevPushManager.init(getIntent()); } @Override public void onRegisteredForPushNotifications(String s) { // Insert the code for processing the received token } @Override public void onFailedToRegisteredForPushNotifications(String s) { // Insert the code for tracking integration errors } @Override public void onPushNotificationsReceived(Map map) { // Insert the code to track received notifications } @Override public void onPushNotificationOpened(PushMessage pushMessage, @Nullable ActionButton actionButton) { // Insert the code to track opened notification } } ``` 5. Optional. To set the custom icons to be shown in push-notification on the SDK part, use the following methods:\ To set the small icon: ``` DevToDevPushManager.setCustomSmallIcon(int resourceId); ``` To set the default color of the small icon: ``` DevToDevPushManager.setCustomSmallIconColor(int colorHexadecimal) ``` To set the large icon: ``` DevToDevPushManager.setCustomLargeIcon(int resourceId); ``` Use resources of your app. For example, R.drawable.ic\_launcherIcons which set in the push-notification wizard have priority over the icons which set in these methods. {% hint style="warning" %} **In case you use several push notifications services or would like to use your own implementation of FirebaseMessagingService**, please add the call of the method for displaying messages sent from the devtodev system: {% endhint %} ``` DevToDevPushManager.displayPushNotification(Context context, RemoteMessage remoteMessage); ``` For example: ``` public class MyFirebaseMessagingService extends FirebaseMessagingService { @Override public void onMessageReceived(RemoteMessage remoteMessage) { Map data = remoteMessage.getData(); if (data != null) { if (data.containsKey("_k")) { DevToDevPushManager.displayPushNotification(this, remoteMessage); } else { showNotification(remoteMessage); } } } } ``` ## Changing the application settings in devtodev system 1\. Go to [Firebase console](https://console.firebase.google.com/) and then to your project settings. On the Cloud messaging tab get the Firebase Cloud Messaging token of your project. ![](https://www.devtodev.com/upload/images/6%289%29.png) 2\. Proceed to Settings of your app in devtodev. ![](/files/-M4SRFz2Ydu2T5p4b1Ye) 3\. Go to Integration page and insert the previously received Firebase Cloud Messaging token to the FCM token field in Push notifications section. ![](/files/-M4ST26oGxcbNPkMp3Kz) 4\. If the Firebase Cloud Messaging token is correct, you will see the following result ![](/files/-M4STdF3AeQYCDGAPua2) ## Creating a new push notification in devtodev interface 1. Open PUSH NOTIFICATIONS section and click on 'Add new campaign" button 2. Fill in campaign name, select an app for delivery\* 3. Choose user group to send a message. You can choose existing segment or create a new one 4. Enter notification details 5. Make some tests and correct the message if it's required 6. Schedule the delivery 7. That's it! {% hint style="warning" %} You can create a campaign only after at least one push token comes from devtodev SDK integrated to your application. Otherwise the app will not be displayed in the list. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
