Android

First to start Android integration, be sure that Setup – Firebase setup was fully completed.

Note

Push Notifications are available from Targets API level 19 (KitKat) and Android 4.4, and later.

  1. Put a google-services.json into the app-level folder of the app.
  2. Add the Google Services package into the app:
    1. Into the root-level Gradle file build.gradle add the Google Service plugin: 
      buildscript {

  repositories {
    google()  // Google's Maven repository
  }

  dependencies {
    // ...
    classpath 'com.google.gms:google-services:4.3.10'  // Google Services plugin
  }
}

allprojects {
  // ...

  repositories {
    google()  // Google's Maven repository
    // ...
  }
}
    2. In the app-level Gradle file build.gradle, apply the plugin:
      app/build.gradle
      apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'  // Google Services plugin

android {
  // ...
}

  3. Integrate the Firebase SDK.

    1. Into the app-level gradle file build.gradle declare dependencies with/without Firebase Android BOM:

      app/build.gradle
      dependencies {
  implementation platform('com.google.firebase:firebase-bom:29.0.0')

  implementation 'com.google.firebase:firebase-messaging'
  implementation 'com.google.firebase:firebase-analytics' // if Firebase Analytics required 
}
      app/build.gradle
      dependencies {
  implementation 'com.google.firebase:firebase-messaging:23.0.0'
  implementation 'com.google.firebase:firebase-analytics:20.0.0' // if Firebase Analytics required
}
      app/build.gradle
      dependencies {
  implementation platform('com.google.firebase:firebase-bom:29.0.0')

  implementation 'com.google.firebase:firebase-messaging-ktx'
  implementation 'com.google.firebase:firebase-analytics-ktx' // if Firebase Analytics required
}
      app/build.gradle
      dependencies {
  implementation 'com.google.firebase:firebase-messaging-ktx:23.0.0'
  implementation 'com.google.firebase:firebase-analytics-ktx:20.0.0' // if Firebase Analytics required
}

    2. Add the service in the manifest:

      app/src/main/AndroidManifest.xml
      <service 
    android:name=".java.MyFirebaseMessagingService"
    android:exported="false">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT" />
    </intent-filter>
</service>
      app/src/main/AndroidManifest.xml
      <service
    android:name=".kotlin.MyFirebaseMessagingService"
    android:exported="false">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT" />
    </intent-filter>
</service>

    3. Create the FirebaseMessaging.getInstance().getToken() method to receive the current token. MainActivity class example:

      public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ActivityMainBinding binding = ActivityMainBinding.inflate(getLayoutInflater());
        setContentView(binding.getRoot());

        binding.logTokenButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                FirebaseMessaging.getInstance().getToken()
                    .addOnCompleteListener(new OnCompleteListener<String>() {
                        @Override
                        public void onComplete(@NonNull Task<String> task) {
                            if (!task.isSuccessful()) {
                                return;
                            }

                            String token = task.getResult();
                            String msg = getString(R.string.msg_token_fmt, token);
                            // send request to the NeuCurrent method for token registartion according to Swagger UI
                        }
                    });
            }
      }
    }
}

      class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(binding.root)

        binding.logTokenButton.setOnClickListener {
            FirebaseMessaging.getInstance().token.addOnCompleteListener(OnCompleteListener { task ->
                if (!task.isSuccessful) {
                    return@OnCompleteListener
                }

                val token = task.result
                val msg = getString(R.string.msg_token_fmt, token)
                // send request to the NeuCurrent method for token registartion according to Swagger UI 
            })
        }
    }
}

      Request sending with NeuCurrent API

      Please, notice that in the code you should send a HTTP request to NeuCurrent API with a received device token on https://app.neucurrent.com/push/api/v1/device-token/add. Docs: https://app.neucurrent.com/push/api/v1/docs

    4. Create MyFirebaseMessagingService file and add the regenerated token receiving method:

      public class MyFirebaseMessagingService extends FirebaseMessagingService {
    @Override
    public void onNewToken(String token) {
    // send request to the NeuCurrent method for token registartion according to Swagger UI
    }
}

      class MyFirebaseMessagingService : FirebaseMessagingService() {
    override fun onNewToken(token: String) {
    // send request to the NeuCurrent method for token registartion according to Swagger UI
    }
}

  4. Congratulations! You've finished the integration process.
