Firebase Quickstart Samples for Android

Firebase Quickstarts for Android

A collection of quickstart samples demonstrating the Firebase APIs on Android. For more information, see https://firebase.google.com.

Samples

You can open each of the following samples as an Android Studio project, and run them on a mobile device or a virtual device (AVD). When doing so you need to add each sample app you wish to try to a Firebase project on the Firebase console. You can add multiple sample apps to the same Firebase project. There's no need to create separate projects for each app.

To add a sample app to a Firebase project, use the applicationId value specified in the app/build.gradle file of the app as the Android package name. Download the generated google-services.json file, and copy it to the app/ directory of the sample you wish to run.

Custom Notifications when app is in background or killed

Hi,

I'd like to implement custom notification styles when app is in background or is killed. Is there a Firebase broadcast receiver class one could extend to implement the same? Would be very helpful. Thanks.

FCM when app in background

Hi,

The FCM works fine when the app is in foreground and a push comes, but when the app is in background and the system tray notification is clicked , it just opens up the app without passing any intent extras. I have added the click_action in Notification Payload from Advanced option of Firebase Console to open an activity but it dosen't work. I have also added the intent-filter ( handle backgound app section) as in documentation.

How can i open a specific activity using FCM service along with the data i pass when the app is in background or exit state.

Firebase Invite always failed...

I wonder why does always fail (resultCode : 3) about 'Firebase Invites' sample app.
What about others? Why does the fail occur?

google-services.json is missing

where is the google-services.json for the messaging project?

FriendlyPing

I know this is not a place to ask for example requests but I was working on updating the friendlyPing application to use Firebase messaging to get myself familiar with it but I ran into a few different issue with parsing the data. If by any chance you could update that sample to use Firebase messaging that would be highly appreciated. Mostly because friendlyPing also includes an XMPP server example.

Thanks for all your work.

GetInvitation resultCallback is called twice

GetInvitation resultCallback is called when I tap a deep link. But after that if I force stop my app and relaunch the main activity through the launcher, the callback is triggered again.
The first time AppInviteReferral.hasReferral(getIntent())) is true but when it is triggered again it is false.
This is in onCreate of MainActivity:

`       boolean autoLaunchDeepLink = false;`
`       AppInvite.AppInviteApi.getInvitation(mGoogleApiClient, this, autoLaunchDeepLink)`
`                .setResultCallback(`
`                        new ResultCallback<AppInviteInvitationResult>() {`
`                            @Override`
`                            public void onResult(@NonNull AppInviteInvitationResult result) {`
`                                if (result.getStatus().isSuccess()) {`
`                                    Intent intent = result.getInvitationIntent();`
`                                    Intent launchGameIntent = new Intent(MainActivity.this, GameActivity.class);`
`                                    startActivity(launchGameIntent);`
`                                } else {`
`                                    Log.d("tag", "getInvitation: no deep link found.");`
`                                }`
`                            }`
`                        });`
`    }     `

subscribe to topic button not creating a topic in the firebase console

In the messaging quickstart app, the subscribe to news button is suppose to create a "news" topic in the firebase console, but even after I click it, the firebase console still shows the "This project does not have any topics" message when I click the topic bubble.

I can send notifications when I click the "User segment" button and when I click the "Single device" button. So firebase is aware of the installation of the app on the device and the token that was created for the device. It's just the subscribing to a topic feature that is not successfully communicating with firebase.

D/FirebaseInstanceId: background sync failed: AUTHENTICATION_FAILED

Hi,

I am trying Firebase Cloud messaging. I cloned this project and created google.service.json as per instruction (https://firebase.google.com/docs/android/setup#prerequisites) and put that file under quickstart-android\messaging\app folder. But I keep getting

D/FirebaseInstanceId: background sync failed: AUTHENTICATION_FAILED

Also, when i click on Log Token button in the emulator, i getnull token.

Can someone please help me?

Isn't there any Authentication by email yet?

Hi

I've already checked in email authentication firebase console.

firebase console -> Auth -> email template
you can see those three menus in there.(email authentication, change password, change email address)

But I couldn't see any api in android api document.(email authentication, change email address)
(I found sending change password api)

How can I clone this project?

Hi guys,

I am sorry for being a noob at the moment. I tried to clone the whole project to try and test it out.
But when I tried to clone it using Android Studio 2.1.2 (Checkout From Version Control -> Github -> https://github.com/firebase/quickstart-android.git -> Create project from existing sources ), I just got a series of folders but couldn't run it.

I am having a problem with the Gradle if I chose

"Import project from external model"

saying

"The project is using an unsupported version of Gradle. Please point to a supported Gradle version in the project's Gradle settings or in the project's Gradle wrapper (if applicable.)"

So I am quite at a loss on how to try cloning the project and see how this works. Hope someone with a good soul can help out. Thanks!

Firebase Dynamic links always returned CANCELED

I'm using dynamic links for my app.

I've followed the tutorial step-by-step and I'm able to open the app by clicking on the link posted on facebook.

But when I invoke getInvitation, I always have CANCELED as status of AppInviteInvitationResult.

    AppInvite.AppInviteApi.getInvitation(mGoogleApiClient, this, false).setResultCallback(
            new ResultCallback<AppInviteInvitationResult>() {
                @Override
                public void onResult(@NonNull AppInviteInvitationResult result) {
                    if (result.getStatus().isSuccess()) {
                        // Extract deep link from Intent
                        Intent intent = result.getInvitationIntent();
                        String deepLink = AppInviteReferral.getDeepLink(intent);

                        // [END_EXCLUDE]
                    } else {
                        Log.d("StartActivity", "getInvitation: no deep link found.");
                    }
                }
            });

Into debug, I can see that result.getStatus() returns CANCELED, but the click on lick open the app correctly.

Where I'm wrong?

Could not find com.firebaseui:firebase-ui-database:0.4.0.

This is a known issue, firebase-ui-database is currently propagating to jCenter and should be available by the end of the day.

If you want to try the sample sooner, you can install FirebaseUI locally.

Can Firebase console push notification if apps is closed? (User swipe away with the long click menu)

I have tried developing a firebase notification apps with this MyFirebaseMessagingService link and MyFirebaseInstanceIDService link example that will receive notification from the console. However, if I close the apps by swiping away the app from the task manager, the app will no longer be able to receive any notification.

I have tried using a service that return START_STICKY and using it to start the MyFirebaseMessagingService but still couldn't receive any notification.

Is this how the firebase push notification intended to perform or am I doing it wrongly?

Extra Info. : My apps is working if I only click back but not if I swipe it away in task manager.

firebasedatabase.getinstance vs new firebase

why in your tutorial video it is used :
Databasereference mRootRef = FirebaseDataBase.getInstance().getReference();
but at firebase.com in docs they use:
Firebase rootRef = new Firebase("https://docs-examples.firebaseio.com/web/data");
-what's the difference ?when we should use 1st one & when the 2nd one?? :S

The code is not executed at onMessageReceived ()

This method onMessageReceived () is not called when the app in the background. only when in the foreground. when I send a push msg from FCM console, it shows a notification as of a hidden implementation in the FCM Library itself that overrides my implemntation.

The documentation is also a bit vague.
public void onMessageReceived (RemoteMessage message)

Also: Google Play Services
Called when a message is received. This is also called when a notification message is received while the app is in the foreground. The notification parameters can be retrieved with getNotification().

Firebase auth error -23, "limits exceeded" on staging server

I can authenticate the user on iOS without any issues, so Firebase is accepting auth requests for this user. It is working for iOS auth on both our staging AND production Firebase URLs.

However, on Android simulator/device I cannot login with same user on the staging Firebase.

I have tried using older login example with 'com.firebase:firebase-client-android:2.0.3+' as we well as newer example using Google GSM and com.google.firebase:firebase-auth:9.0.2. Both return auth error -23 with message "limits exceeded".

Does this require some additional settings or config in the Firebase dashboard?

Thanks,
Anthony

Email not appearing for FirebaseUser when used with GoogleSigninActivity

This may have been inherited from FirebseAuth, when logging in with Google account the firebase user email is empty/null.
Seems we have to manually update email whereas photo Url is seamlessly picked up by firebase user !

Till few days ago (com.firebase) when users were added with google sign-in, email was added automatically as seen on users console.

Authentication failed refresh Token

I'm using Firebase Authentication 9.0.2 (Facebook, Google, email/password or anonymous) in my Android app, this part works correctly.

mAuthListener = new FirebaseAuth.AuthStateListener() {
        @Override
        public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
            FirebaseUser user = firebaseAuth.getCurrentUser();
            if (user != null && !flagAuth) {
                // User is signed in
            } else if (user == null) {
                // User is signed out
            }
        }
    };

After this, I'm listening on database.getReference(".info/connected") and database.getReference(".info/authenticated"), first time I'm connecting these 2 values are true for all authenticated providers. When I'm restarted my application, it is always true.

final DatabaseReference refAuthenticated = database.getReference(".info/authenticated");
    refAuthenticated.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
            boolean connected = dataSnapshot.getValue(Boolean.class);
            if (connected) {
                AppLog.d("Authenticated");
                });
            } else {
                AppLog.d("No more Authenticated");
            }
        }

        @Override
        public void onCancelled(DatabaseError databaseError) {
            AppLog.d("Listener was cancelled at .info/authenticated");
        }
    });

But after 1 hour (when my token is expired), Firebase SDK has to refresh the token automatically but it failed with this error

pc_0 - Authentication failed: expired_token (Auth token is expired)

Or this one

pc_0 - Authentication failed: invalid_token (Invalid claim 'kid' in auth header.)

I have checked my SHA-1 key in my Firebase project and it is correct.

Anybody can help me?
Thank you.

in order to compile code.

Topic not being created with FirebaseMessaging.getInstance().subscribeToTopic(...)

Hello,

I am able to successfully send notifications to a single device and I am able to send them to a user segment, but in the Firebase Notifications console for my application for Target=Topic it shows "This project does not have any topics" even though I called FirebaseMessaging.getInstance().subscribeToTopic() from my Android application with several different topic names days ago.

The documentation for this is very sparse. Does this call not actually create a new topic? Is an HTTP call required to create the topic before the Android client can subscribe to it through this API?

If this API should indeed create the topic then how long does it take? I have been waiting almost 3 days now for it to appear in the console. I do not see any exceptions or errors generated on the client side when I make the call.

This was from a Samsung Galaxy S6 with Marshmallow.

Thanks,
Thomas

FirebaseMessagingService Custom notifcations/other tasks when app is in backgorund

ISSUE FIXED

I have switched from gcm to firebase messaging and I regret it now.

I know it clearly states in documentation that Notifications delivered when your app is in the background. In this case, the notification is delivered to the device’s system tray.
A user click on a notification opens the app launcher by default.

But onMessageReceived is not called when the app is background or killed
that means i don't know when a messaged is received and cant really write code according to that
and since my application needs to perform other task when this messaged is received, I cant find a way to do it.

and Additional Information This is the from only the tests i conducted from the firebase console and not the apis

and please explain this a little more:
When you send a notification from the Firebase console and your app is in the background it cannot be customized.

If you want custom background notifications you should use the FCM API to send data messages to your app and handle them in the FirebaseMessagingService where you can decide how the notification should look.

ISSUE TO FIX

1) I WANT DO CREATE A CUSTOMIZED MESSAGE WITHOUT THE DATA FROM THE MESSAGE AND ALSO PERFORM OTHER THINGS WHEN I RECEIVE THE MESSAGE.

2) And if onMessageReceived is not called then what part of the service or method is called ?

3) Is moving back to GCM my only option ?

But the idea of it only sounds so bad.
Please fix this in the future release .

PS: I have read through the closed issue which still doesn't solve this problem

HERE IS THE PROBLEM AND SOLUTION

Problem

Switching from the old gcm to new FirebaseMessagingService i thought it would be good to test hence i created messages using firebase console and only found that when app is background my custom notification was not working and Firebase onMessageReceived not called when app in background

In SHORT SOLUTION

It happens only when sending messages through console of firebase and not the apis

Solution

I tried to create messages from the api and only then did i realize that the Firebase onMessageReceived not called when app in background issue happens only when creating messages from the Firebase Console and not when sent from API

PS: FIREBASE TEAM PLEASE CLEARLY MENTION THIS IN THE CONSOLE, SINCE MANY PEOPLE HAVE THE SAME QUESTION

Request for user profile from GMail is returning null

I would like to retrieve the user's profile picture and name after google login:

            .requestIdToken(getString(R.string.default_web_client_id))
            .requestEmail()
            .requestProfile()
            .build();

...
mAuthListener = new FirebaseAuth.AuthStateListener() {
        @Override
        public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
            FirebaseUser user = firebaseAuth.getCurrentUser();
            if (user != null) {
                // User is signed in
        Log.v(TAG,"pic "+user.getPhotoUrl()+" name "+user.getDisplayName());
            } else {
                // User is signed out
                Log.d(TAG, "onAuthStateChanged:signed_out");
            }
        }
    };

In the logcat am getting: pic null name null

Get facebook user's info

I have no clue about getting user's facebook info from the current Firebase version. In old versions, onAuthenticated callback function had AuthData object which used to get user's info. How can this be done now?

FirebaseRemoteConfigFetchException when fetching Remote Config

Using GMS and Firebase 9.0.2

I set up my app with Firebase, features like Analytics or Notifications are already working. Now I tried to add Remote Config but every time I call fetch, I get a com.google.firebase.remoteconfig.FirebaseRemoteConfigFetchException.

I'm not doing anything special. Basicly, all I do is

FirebaseRemoteConfig.getInstance().fetch().addOnCompleteListener {
    toast(it.isSuccessful.toString())
    it.exception?.printStackTrace()
}

Question: A/B testing +RemoteConfigs- how to track, and is cacheExpiration needed?

I can't find a sample or tutorial about how to track the current variant of the experiment.
For example, suppose we have 2 variants for the position of an button, and we wish to track how many people pressed the button on each variant. I'd also like to know where in the console website I need to see the stats.

I also don't understand the need for cacheExpiration when calling :

mFirebaseRemoteConfig.fetch(cacheExpiration)

Is it really needed? Shouldn't there be an option that the cache will stay for as long as it can, perhaps removing it upon app-update? Or override it when there is new data from the server?

Google FCM getIntent return null on app is not running

Please help me! I check debug this code extras alway return null when click on new notification, if app is not running, and show good on app is running

    @Override
    public void onNewIntent(Intent intent) {
        Bundle extras = intent.getExtras();
        if (extras != null) {
            if (extras.containsKey("local_notification_message")) {
            }
        }
    }

How to know the data sent to the database has reached successfully?

   mDatabase = FirebaseDatabase.getInstance().getReference();
    Task<Void> base = mDatabase.child("demo").child(id).setValue(story);

    Log.d(TAG, "getEditTextVals: This is after base");
    if(base.isComplete()){

        Log.d(TAG, "getEditTextVals: completed");

    }
    if (base.isSuccessful()){
        Log.d(TAG, "getEditTextVals: successful");
        Intent intent = new Intent(getApplication(), MainActivity.class);
        startActivity(intent);
        finish();

    }

What this doesn't do is, it doesn't call isComplete, or isSuccessful, meaning those are all fasle.

Why the expiry time of Firebase custom auth token is limited to max 1Hr(3600sec) ?

exp The time, in seconds, at which the token expires. It can be at a maximum 3600 seconds later than iat.

I'm doing a chat application using Firebase. where I need to listen for incoming messages most of the time. If auth token expires every hour, its difficult for me to maintain the valid session all the time :(

In Legacy Firebase system, token expiry time was too flexiable; where we can adjust TTL value from 1Hr to as many years!! Never expire option was also there!

Why the current Firebase API, is forcing the client to refresh the Auth token every hour?

Also, I couldn't verify the Auth session length at client side,
In Firebase 9.0.0 API, how to check the user has valid Auth session or not?

Kindly help me on this.Thanks in advance!

Failed to load module descriptor class

There seems to be problem with the app or perhaps I am running it in the wrong way. I am able to start the app. However, if I tap on "Sign in" the app does not respond, but the Android Monitor shows the following error:

I'm using the Genymotion emulator and since somewhere around last week, my app won't launch anymore when I use Remote Config. Everytime the app starts, I get the following stacktrace:
