How to get Firebase Cloud Messaging token in Xamarin?

I have a Xamarin android application and I need to get Firebase Cloud Messaging Token.
I added a file with the following class in my Android Project :
[Service]
[IntentFilter(new[] { "com.google.firebase.MESSAGING_EVENT" })]
[IntentFilter(new[] { "com.google.firebase.INSTANCE_ID_EVENT" })]
public class MyFirebaseIIDService : FirebaseMessagingService
{
const string TAG = "MyFirebaseMsgService";
public override void OnNewToken(string token)
{
base.OnNewToken(token); // << Breakpoint here
SendRegistrationToServer(token);
}
public void SendRegistrationToServer(string token)
{
// Do something with the token
}
}
and my AndroidManifest.xml :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="13" android:versionName="13.1" package="com.MyApp.app" android:installLocation="internalOnly">
<uses-sdk android:minSdkVersion="18" android:targetSdkVersion="30" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CAMERA" />
<application android:label="MyApp" android:icon="#mipmap/launcher_foreground" android:hardwareAccelerated="true" android:debuggable="true">
<receiver android:name="com.google.firebase.iid.FirebaseInstanceIdInternalReceiver" android:exported="false" />
<receiver android:name="com.google.firebase.iid.FirebaseInstanceIdReceiver" android:exported="true" android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="${applicationId}" />
</intent-filter>
</receiver>
</application>
</manifest>
I deploy the application to an emulated device but the breakpoint is never reached. The app is deployed though and running.
I was wondering if this code is enough or whether this class has to be referenced somewhere else.
I'm aware that this code is run only once when the application is installed. So every time I uninstall the application before testing again.
Does anyone have an idea how to solve that please ?
Thanks.
Cheers,

If you want to get the Firebase Cloud Messaging Token, you could use the code below.
var FCMtoken = FirebaseMessaging.Instance.GetToken().GetResult(Java.Lang.Class.FromType(typeof(InstallationTokenResult))).ToString();
This service MyFirebaseIIDService implements an OnTokenRefresh method that is invoked when the registration token is initially created or changed.
OnTokenRefresh is invoked infrequently: it is used to update the token under the following circumstances:
When the app is installed or uninstalled.
When the user deletes app data.
When the app erases the Instance ID.
When the security of the token has been compromised.
You could check the MS docs for more details. https://learn.microsoft.com/en-us/xamarin/android/data-cloud/google-messaging/remote-notifications-with-fcm?tabs=windows#implement-the-firebase-instance-id-service

Android GCM - Cannot receive Messages

The AndroidManifest.xml:
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<!-- Receiver for GCM Messages-->
<receiver
android:name="com.google.android.gms.gcm.GcmReceiver"
android:exported="true"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<action android:name="com.google.android.c2dm.intent.GCM_RECEIVED_ACTION"/>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="de.comp.module.client" />
</intent-filter>
</receiver>
<service
android:name="de.comp.module.client.gcm.GCMBroadcastIntentService"
android:exported="false">
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
</intent-filter>
</service>
The GCMBroadcastIntentService class:
public class GCMBroadcastIntentService extends GcmListenerService {
#Override
public void onMessageReceived(String from, Bundle extras) {
if (extras.containsKey("message")) {}
}
}
The onMessageReceived() method is never called. The server works fine, the messages are send to Google GCM without any errors, but they never arrive at the device. I also use google-services.json which is stored in the folder /app. In my app the user can loggin after a new installation. In this case a new GCM token is requested and send to the server. So it should be correct and up to date.
What is missing? Thanks for your help.
EDIT:
public class GCMRegistrationIntentService extends IntentService {
#Override
protected void onHandleIntent(Intent intent) {
try {
// register server key to GCM
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
String regid = gcm.register(getString(R.string.gcm_defaultSenderId));
// Request new token for this server key
InstanceID instanceID = InstanceID.getInstance(this);
String token = instanceID.getToken(getString(R.string.gcm_defaultSenderId), GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
// Subscribe to topic channels
subscribeTopics(token);
...
}

you must register the sender id in the Gcm:
GoogleCloudMessaging gcm=null;
try {
if (gcm == null) {
gcm = GoogleCloudMessaging.getInstance(getContext());
}
String regid = gcm.register(SENDER_ID);
} catch (IOException ex) {
msg = "Error :" + ex.getMessage();
}
note that SENDER_ID is the id of the server that sends the notification

Use FCM instead of GCM.Check this official links. FCM is a new Version of GCM

Try to start from the beginning.
Make sure SENDER_ID matches the project number in console.
Make sure you implement registration IntentService, device registration is successful and you receive push token (GCM registration id).
Make sure you pass it to server.
Not forget to implement InstanceIDListenerService.
Add missing services to manifest.
Start everything from the beginning and pay attention at each step
https://developers.google.com/cloud-messaging/android/client

Set up the GCM client according to https://developers.google.com/cloud-messaging/android/client
If you still not get a call to onMessageReceived(), you can check whether the problem is somwhat similar to GcmListenerService.onMessageReceived() not called
Also GCM requires a Google account for Pre-4.0.4 devices if you are using the deprecated library (GCMRegistrar.register), . If yes you need to make an entry in AndroidManifest as
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
Refer GET_ACCOUNTS permission while using GCM - Why is this needed?

Parse Installation not getting DeviceToken

I am trying to use parse for push notification in android, I am registering parse in the Application class like this:
#Override
public void onCreate() {
super.onCreate();
Parse.initialize(this, "***************", "***************");
}
I am subscribing to push like this in the main activity:
#Override
protected void onCreate(Bundle savedInstanceState) {
ParsePush.subscribeInBackground("", new SaveCallback() {
#Override
public void done(ParseException e) {
if (e == null) {
ParseInstallation.getCurrentInstallation().saveInBackground(new SaveCallback() {
#Override
public void done(ParseException e) {
if (e == null) {
String deviceToken = (String) ParseInstallation.getCurrentInstallation().get("deviceToken");
Log.e("MainActivity", "device toekn " + deviceToken);
} else {
Log.e("MainActivity", "failed to subscribe for push " + e.getLocalizedMessage());
}
}
});
} else {
Log.e("MainActivity", "failed to subscribe for push", e);
}
}
});
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
And here is my manifest section the apply to parse:
<service android:name="com.parse.PushService" />
<receiver android:name="com.parse.ParseBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.USER_PRESENT" />
</intent-filter>
</receiver>
<receiver android:name="com.parse.ParsePushBroadcastReceiver"
android:exported="false">
<intent-filter>
<action android:name="com.parse.push.intent.RECEIVE" />
<action android:name="com.parse.push.intent.DELETE" />
<action android:name="com.parse.push.intent.OPEN" />
</intent-filter>
</receiver>
<receiver android:name="com.parse.GcmBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<!--
IMPORTANT: Change "com.parse.starter" to match your app's package name.
-->
<category android:name="com.****" />
</intent-filter>
</receiver>
however, device token returns null most of the times and the device has no device token in the parse dashboard, therefor, my device is not getting the push notifications.
The odd part is that sometimes it does work, i do get deviceToken and the installation object does get the push, has anyone encountered this behavior?

This problem was eventually solved, a simple mistake in the Application name in the tag of the manifest in the tag.
since the code i posted here was "com.***" no one could have helped, i apologize.

I encountered this problem and i solved it by modifying my AndroidManifest file.
It appears that you can configure parse to either use "Parse Push Network" or GCM (Google Cloud Message).
Parse uses its own push network for apps that want to avoid a dependency on the Google Play Store, and for devices (like Kindles) which do not have Play Store support.
Thus it is important to set the below in other to use GCM.
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<permission android:name="YOUR_PACKAGE_NAME.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission android:name="YOUR_PACKAGE_NAME.permission.C2D_MESSAGE" />
Replace YOUR_PACKAGE_NAME in the declarations above with your application's package name. Also, make sure that com.parse.GcmBroadcastReceiver and com.parse.PushService are declared as children of the element:
This worked for me, it might as well work for you.
Read this to get a full understanding

I guess you are using version 1.9.3. In version 1.9.4 they have fixed the problem. Check the release notes.

It could be useful to set parse logging to verbose to help debug further:
Parse.setLogLevel(Parse.LOG_LEVEL_VERBOSE);
With that I noticed that I was using the wrong "sender_id" in my manifest:
<meta-data android:name="com.parse.push.gcm_sender_id"
android:value="id:123456789"/>
I'm using my own GCM which your not doing here...but LOG_LEVEL_VERBOSE might help others debug this.

Why are you saving the installation if you're not adding anything to it? ParseSDK does that for you already.
You must pass a valid "channel" parameter into subscribeInBackground:
This is the channel that parse uses to push with; without it you won't get any pushes at all.
https://parse.com/docs/android/api/com/parse/ParsePush.html#subscribeInBackground(java.lang.String,%20com.parse.SaveCallback)
In addition make sure you've added the needed tag in your manifest for parse push to work properly - and the needed just like it explained here:
https://parse.com/docs/android/guide#push-notifications-receiving-pushes

Can't send push from Parse.com

I had a project with Parse in my app, but I've changed the project (and so the keys) and my pushes (test or normal) doesn't get sent from Parse.
When I try to send them I'm notified that it's going to be received by 2 recipients:
My Client push is ENABLED:
Although I think it's not needed, I've got my GCM credentials:
I've tried with a custom ParsePushBroadcastReceiver extended on Android and logging onReceive
I've tried to sign as release and debug.
I've tried with Wi-Fi, 3G and 4G.
I've tried to clear data, uninstall the app, rebooting.
My permissions on AndroidManifest.xml are:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<permission android:protectionLevel="signature"
android:name="taggie.me.permission.C2D_MESSAGE" />
<uses-permission android:name="taggie.me.permission.C2D_MESSAGE" />
My application is:
<application
android:name=".MainApplication"
android:allowBackup="true"
android:icon="#drawable/logo_help"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
which code is:
public class MainApplication extends Application {

super.onCreate();
Parse.initialize(this, "YBi4ki505TcwKSNEIW7gkFCdWvjHC9yNJmrZHBGR", "APwUw3laazYRhvkSRwZZqpxsROUjH5jWP6QzeHiq");
ParseInstallation.getCurrentInstallation().saveInBackground();
}
}
and the rest of my AndroidManifest.xml is:

but THE PROBLEM IS HERE
I don't get notifications, and when I send them I can see this:
Does anyone has a clue before shooting myself? Thank you :)
This is incredible, I've tried to send the apk to one friend of mine... and he gets the push notifications but I don't! why could it be possible?
I've just opened the port 8253 as I've seen some posts reporting this, but it's still not working. :'(

I had a similar issue that was resolved in a strange way, but still - might help:
if you re-install (actually re-deploy, sometimes uninstalling sometimes just running over an existing apk) your application on a device, it might create several entries for device tokens that point to the same actual device (inside the Parse dashboard, go to Core, you can see the full table there), in which case - the system doesn't always know which is the correct physical device.
this might explain:
a. the dashboard telling you it will send more than 1 message (assuming only 1 was supposed to be sent).
b. your friend getting the push (he has only 1 valid device token)
Anyway - the refresh button on the Core page didn't help, but - manualy sending a push from the dashboard would result in the device receiving multiple pushes (for the number of duplicates it had in the table), and then, re-entering the Core table page would automatically clear the duplicates.
from there on - Pushes got back to normal.
you might need another clean, complete removal and re-installation on the device.
Hope this Helps!
Note: GCM Credentials were'nt needed in my case.

The main problem is I was working with Genymotion.
Being a simulator, push notifications should ARRIVE or NOT ARRIVE at all, but they were arriving sometimes. I can't explain why.

In your parseApplication class declare the channel. If you are sending notifications you have to set the channel. See this ParsePush.subscribeInBackground . It is describing the channel .
public class ParseApplication extends Application {
#Override
public void onCreate() {
super.onCreate();
System.out.println("Application");
Parse.initialize(this, "86q5mwgypd1Q2URFV6kJh5MBPmUpuPvoN3lTdeWx", "OhrkrJTuTwtbMprYtiywnQ3f4wnQdr5pitmI7tNt");
ParsePush.subscribeInBackground("temboo", new SaveCallback() {
#Override
public void done(ParseException e) {
if (e == null) {
Log.d("com.parse.push", "successfully subscribed to the broadcast channel.");
} else {
Log.e("com.parse.push", "failed to subscribe for push", e);
Toast.makeText(ParseApplication.this, "Failed to subscribe for push.", Toast.LENGTH_SHORT).show();
}
}
});

This works for me.
Parse.enableLocalDatastore(this);
// Add your initialization code here
Parse.initialize(this, APP_ID, CL_ID);
ParseInstallation.getCurrentInstallation().saveInBackground();
ParseUser.enableAutomaticUser();
ParseACL defaultACL = new ParseACL();
// Optionally enable public read access.
// defaultACL.setPublicReadAccess(true);
ParseACL.setDefaultACL(defaultACL, true);
// IF NEEADED
String topic ="YOUR_TOPIC";
System.out.println(topic);
ParsePush.subscribeInBackground(topic, new SaveCallback() {
#Override
public void done(ParseException e) {
if (e == null) {
Log.d("com.parse.push",
"successfully subscribed ");
} else {
Log.e("com.parse.push", "failed ", e);
}
}
});

PARSE: Push Notifications "deviceToken" undefined

This is the situation in my Installation page on Parse Console:
As you see some devices have the "deviceToken" and some do not have the "deviceToken". This is not good because every device should have the deviceToken in order to work.
How is this possible? This is a serious problem because the ones that do not have the deviceToken do not receive push notifications!
I've followed all the instructions on Parse.com and implemented everything as they said, even with the help of their blank project and with the help of various questions on the web. But nothing fixed my problem and now I can't do anything.
The only thing I can think about is that before my application (it is already on the Store) used to use Google Cloud Messaging and then with this new update I've decided to change the system and use Parse removing completely GCM system. Is there maybe a conflict between the two systems?
I need to fix this as you can imagine this is a serious bug and now 3/4 of my users do not receive push notifications.
If you download the app and install it: everything is good, the deviceToken is ok. If you update the app because there already was a version with GCM on the device:
some devices register in Parse good, without any problem
some devices register in Parse but without the deviceToken
For the devices that do not have the deviceToken I've tried a lot of things: inserting a deviceToken manually, uninstall and reinstall the application, delete the specific row on Parse, etc. But nothing good... Still facing this problem.
MY CODE
Application.java
public class Application extends android.app.Application {
public Application() {
}
#Override
public void onCreate() {
super.onCreate();
// Initialize the Parse SDK.
Parse.initialize(this, "x", "x");
// Specify an Activity to handle all pushes by default.
PushService.setDefaultPushCallback(this, MainActivity.class);
}
}
MainActivity.java
In my mainActivity I just concatenate the deviceToken (in my case it is the installationId) into my userAgent: and this work fine: I always have the installationId without any problem! And this is the only thing I am doing in my MainActivity (do I need to do anything else? saveInBackground, callback, etc..?)
deviceToken = ParseInstallation.getCurrentInstallation().getInstallationId();
webSettings.setUserAgentString(userAgent + " ||" + deviceToken);

Thank you.

Are you using 2 user profiles at the same time on the tablet? Because I've had exactly the same problem and from my experience there is a conflict between the profiles. Infact, in my situation one device was registering 2 rows into the Parse database. One with the deviceToken and one with "undefined" deviceToken.
Unfortunately I've never solved this problem, I guess this is a bug from Parse.

It could be useful to set parse logging to verbose to help debug further:
Parse.setLogLevel(Parse.LOG_LEVEL_VERBOSE);
With that I noticed that I was using the wrong "sender_id" in my manifest:
<meta-data android:name="com.parse.push.gcm_sender_id"
android:value="id:123456789"/>
That might not be the exact solution, but LOG_LEVEL_VERBOSE might help debug this.

Some installations do have a GCM Registration Id set up in their deviceToken column, which is a good indication that your setup is correct. Is it definitely possible for an installation to lack a GCM Registration Id:
The device may not have access to Google Services Framework (e.g. Amazon Kindle Fire). If you have set up the non-GCM ParsePush receiver, pushes to these devices should still get delivered.
The app has been deleted from the device, and thus it has been unregistered from GCM. We do not automatically delete installations in this case as that could potentially lead to unintended data loss, given that you're allowed to store arbitrary data in your installation class.
Google Services Framework may have been unavailable when the device attempted to register itself.
In the first two scenarios, this is working as expected and it's not something to generally worry about.

Are those simulator users? From my experience if you are running an installation on your simulator it does not auto setup the device token.

I had been struggling with this problem for a long time until I recently realized what has been going on. Not only does the package name need to match, but you also need to include the build flavor in your declaration.
If you followed the parse tutorial and replace com.parse.starter with your package name, you are done if you have no build flavor, but if you do you need to make sure to include that as such:
com.packagename.build_flavor{debug, release, etc.}

You may create a class and extends Application to initialize your app. Such that initialize ParsePush and updateParseInstallation.
Sample code:
public class YourappApplication extends Application {
#Override
public void onCreate() {
super.onCreate();
Parse.initialize(this,YOU_PARSE_applicationId, YOU_PARSE_clientKey);
ParseInstallation.getCurrentInstallation().saveInBackground();
ParsePush.subscribeInBackground("", new SaveCallback() {
#Override
public void done(ParseException e) {
if (e == null) {
Log.d("com.parse.push", "successfully subscribed to the broadcast channel.");
} else {
Log.e("com.parse.push", "failed to subscribe for push", e);
}
}
});
}
public static void updateParseInstallation(ParseUser user) {
ParseInstallation installation = ParseInstallation.getCurrentInstallation();
installation.put("userId", user.getObjectId());
installation.saveInBackground();
}
}
And then in your LoginActivity: updateParseInstallation
ParseUser.logInInBackground(username, password, new LogInCallback() {
#Override
public void done(ParseUser parseUser, ParseException e) {
setProgressBarIndeterminateVisibility(false);
if(e == null){
YourappApplication.updateParseInstallation(parseUser);
Intent intent = new Intent(LoginActivity.this,
MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
}
}
});

I had similar issue after renaming module.
Try 'Clean Project' followed by 'Rebuild Project'

I had this problem but in a cordova app using the phonegap-parse-plugin. I had to edit the android java code in the plugin to fix, so effectively the same.
Try adding this save BETWEEN the Initialize and the setDefaultPushCallback:
ParseInstallation.getCurrentInstallation().save();
It has to be between them to work.

My problem was that I was missing this permission in the manifest:
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
Also I had to add meta-data just before
<service android:name="com.parse.PushService" />:
<meta-data
android:name="com.parse.APPLICATION_ID"
android:value="YourParseApplicationID" />
<meta-data
android:name="com.parse.CLIENT_KEY"
android:value="YourParseClientKey" />
Now check if you can get the deviceToken. Also check your app dashboard in Parse if everything is ok.

I dont know if tghis helps anyone but I was able to get the device token and notification correctly after removing this line from my Application Class containing parse intalation. here is the code. the commented line (removed line) made everything work properly. Can anyone explain why this works?
package com.test.android.push;
import android.app.Application;
import com.parse.Parse;
import com.parse.ParseInstallation;
import com.parse.ParsePush;
public class FarrApplication extends Application {
#Override
public void onCreate() {
super.onCreate();
Parse.initialize(this, "xxxx", "xxxx");
ParseInstallation.getCurrentInstallation().saveInBackground();
ParsePush.subscribeInBackground("---"); // REMOVED AND WORKS
