Step 4 - Set pushidentifier

The pushidentifier is a string that contains the device token for Push notifications. It is the same token that is sent by Firebase and is passed to the SDK using the MobileCore.setPushIdentifier method.

Open your project in Android™ studio. Delete the entire code in MainActivity except the first line which is your package statement.

Paste the following code into MainActivity:

import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;

import com.adobe.marketing.mobile.MobileCore;
import com.google.android.gms.tasks.OnCompleteListener;
import com.google.android.gms.tasks.Task;
import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.InstanceIdResult;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

registerToken();
}

void registerToken() {
FirebaseInstanceId.getInstance().getInstanceId()
    .addOnCompleteListener(new OnCompleteListener<InstanceIdResult>() {
        @Override
        public void onComplete(@NonNull Task<InstanceIdResult> task) {
            if (!task.isSuccessful()) {
                Log.w("Message App", "getInstanceId failed", task.getException());
                return;
            }

// Get new Instance ID token
String token = task.getResult().getToken();

Log.d("Got token", token);

MobileCore.setPushIdentifier(token);
}
});
}

@Override
public void onResume() {
super.onResume();
MobileCore.setApplication(getApplication());
MobileCore.lifecycleStart(null);
}

@Override
public void onPause() {
super.onPause();
MobileCore.lifecyclePause();
}
}

Test your app

Now is a good time to test your app, before going any further.

• Run your app by clicking green arrow or select Run->Run’app’.
• The Android™ emulator should start and you should see your app running with “Hello World” text.
• Open the logcat window. Search for “Got”. You should see the token that was received from Firebase written to the log as shown below. The long string after “Got token” is the pushidentifier that is sent to Adobe Campaign.

Check Mobile Application Subscribers

Log in to your Adobe Campaign Standard instance.
Navigate Administration->Channels->Mobile App(Experience Platform SDK). Open the appropriate mobile application. Tab to the Mobile Application Subscribers tab. You should see a registration token listed.
