In firebase console I can get this source code for java and some adminsdk json file to download. However I'm working in c# xamarin and it doesn't have the setCredential() function. This is java code that I can download in firebase console
FileInputStream serviceAccount = new FileInputStream("path/to/serviceAccountKey.json");
FirebaseOptions options = new FirebaseOptions.Builder()
.setCredential(FirebaseCredentials.fromCertificate(serviceAccount))
.setDatabaseUrl("https://abc-def.firebaseio.com")
.build();
FirebaseApp.initializeApp(options);
But in xamarin, there is no SetCredential function. I can do only things like:
FirebaseOptions options = new FirebaseOptions.Builder()
.SetApplicationId("1:3465124113567:android:81db52b2352255cd")
.SetDatabaseUrl("https://abc-def.firebaseio.com/")
.SetStorageBucket("gs://abc-def.appspot.com")
.SetApiKey("???")
.SetGcmSenderId("???")
.Build();
var firebaseApp = FirebaseApp.InitializeApp(context, options);
How can I use that file? I made couple of tries in SetApiKey, setting some lines from that file, but somehow the application is just crashing on InitializeApp line, without meaningfull explanation in output window. How is it done that my application gets admin privileges in c# - xamarin?
In this question I found that SetCredentials wasn't there always, but all my xamarin.firebase.xxx components are on version 10.2.1 so this shouldn't be problem.
Refer to #Doug Stevenson 's answer, you are using the Firebase Android client library, not the Firebase Admin SDK. You could read the javadoc for FirebaseOptions.Builder in the Android client library :
Android : FirebaseOptions.Builder
Then look at the same class from the java Admin SDK (note the URL is different) :
Admin SDK :
FirebaseOptions.Builder
They are different things, in your project you are using the Android SDK definition and not the admin SDK definition.

I installed firebase with react native expo using expo add firebase, then
I created a file (firebase.tsx) and added the Firebase configuration and initialized the app like in this screenshot with correct values].
I have added the google-services.json and
GoogleService-info.plist to the root of my expo project like the documentation say and i am importing firebase in my api service like this import Firebase from './../../../firebase'.
In my register function I call the firebase create user function
const response = await Firebase.auth().createUserWithEmailAndPassword(values.email.value, values.password.value)
The response is never returned, and if I use . then nothing happens either.
If I log firebase.auth I get an object with my API key and app name, etc. so Firebase is installed, but whenever I call the database for sign in or to access a collection nothing happens.
This is my package.json.
This is my app.json.
I added bundleIdentifier and googleServicesFile to iOS and package and googleServicesFile for Android.
currently Firebase seems not to be working in expo if you are using the android configuration. I have tried the web configuration and it has worked for me. Here is the youtube tutorial for it. Watch from 38:20 to set up.
Unity editor version: 2019.3.15f1
Firebase Unity SDK version: firebase_unity_sdk_6.15.2
Additional SDKs im using: Unity IAP, Gamesparks, Ironsource, Facebook, Appsflyer, GameAnalytics
Platform im using the Unity editor on: Windows
Platform im targeting: Android
Scripting Runtime: IL2CPP
Problem
I am getting data on firebase analytics, but I cannot get crashlytics to report anything. Im stuck on this...
Steps to reproduce:
Add the firebase analytics and crashlytics sdks.
Add the google-services.json GoogleService-Info.plist files somewhere in assets folder
Add this code to initialise the firebase
// Use this for initialization
void Start ()
{
// Initialize Firebase
Firebase.FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(task => {
var dependencyStatus = task.Result;
if (dependencyStatus == Firebase.DependencyStatus.Available)
{
// Create and hold a reference to your FirebaseApp,
// where app is a Firebase.FirebaseApp property of your application class.
// Crashlytics will use the DefaultInstance, as well;
// this ensures that Crashlytics is initialized.
Firebase.FirebaseApp app = Firebase.FirebaseApp.DefaultInstance;
// Set a flag here for indicating that your project is ready to use Firebase.
VisualDebugger.SetText("crashlytics initialised");
}
else
{
UnityEngine.Debug.LogError(System.String.Format(
"Could not resolve all Firebase dependencies: {0}",dependencyStatus));
VisualDebugger.SetText("crashlytics NOT initialised: " + dependencyStatus);
// Firebase Unity SDK is not safe to use here.
}
});
Invoke("IsCrashEnabled", 5f);
}
void IsCrashEnabled()
{
VisualDebugger.AddLine("IsCrashlyticsCollectionEnabled: "+Firebase.Crashlytics.Crashlytics.IsCrashlyticsCollectionEnabled);
}
In order to get the app to run with the facebook sdk installed Ive added these two lines to proguard-user.txt
-keep public class com.facebook.**{public *; }
-keep public class com.facebook.internal.**{ public *; }
and commented out the following lines from mainTemplate.gradle
//implementation 'com.android.support:appcompat-v7:25.3.1' // Facebook.Unity.Editor.AndroidSupportLibraryResolver.addSupportLibraryDependency
//implementation 'com.android.support:customtabs:25.3.1' // Facebook.Unity.Editor.AndroidSupportLibraryResolver.addSupportLibraryDependency
//implementation 'com.android.support:support-v4:25.3.1' // Facebook.Unity.Editor.AndroidSupportLibraryResolver.addSupportLibraryDependency
When I run the app, firebase is initialised successfully. Also Firebase.Crashlytics.Crashlytics.IsCrashlyticsCollectionEnabled returns true.
I crash the app in a number of different ways, then open it again without reinstalling. But no crash reports are sent.
When I watch logcat when starting the app I see this error from firebase each time the app is opened
2020-09-28 16:18:59.332 25773-25847/? E/FirebaseCrashlytics: Failed to retrieve settings from https://firebase-settings.crashlytics.com/spi/v2/platforms/android/gmp/REDACTEDblahblahblah/settings
Update Oct 19, 2020:
Today a developer updated the issue I linked in this answer saying the Firebase team fixed a backend bug last Friday (Oct 16) that was affecting some new Unity Android apps registering w/ Firebase - likely the bug behind your issue. I had already solved the issue in my own project using the below solution, but if you haven't yet updated your project, I recommend running it again and seeing if Crashlytics is working for you now..
I've been dealing with the same issue this week in Unity 2019.4.11f1 - i see the same error message about not being able to retrieve settings, but with my specific project and appIds in the URL.
I found a solution in this Github issue, which suggests the problem is caused by the version of an android library that is a dependency for the Unity Firebase Crashlytics package. My rough understanding is that the firebase-crashlytics-unity library is a wrapper around android library firebase:firebase-crashlytics, and the unity package allows the underlying native Android code to be used from Unity. Version com.google.firebase:firebase-crashlytics:17.10.0 has issues with getting the settings for some Firebase projects on Android. Myself and several others following this issue found forcing Unity to use this specific dependency at version 17.1.1 resolved the issue.
Someone else with the same issue in the thread contacted Firebase support and was told:
The error you are seeing "Failed to retrieve settings" is related to
the SDK version being used. If you go to "Assets > Firebase > Editor>
CrashlyticsDependencies" you can manually update the SDK to point to
the latest Crashlytics SDK version 17.2.2. Please give it a try and if
you continue having issues, let me know.
It turned out this advice wasn't quite right - some of us following the thread then experienced a different issue when using the Android Crashlytics SDK version 17.2.2 with Unity crashlytics version 6.16.0. So I'd specifically recommend trying out the below suggestion or other solutions in the thread to set your Android crashlytics library to v17.1.1.
Changes I made in my project to address this:
First, I updated my unity firebase packages in the package manager to use version 6.16.0. In my project 4 packages were installed - core, analytics, crashlytics, and messaging.
Then I searched for the the Crashlytics package's dependency file - Crashlytics-Dependencies.xml (found by searching project - was in /Library/PackageCache/com.google.firebase.crashlytics#6.16.0/Firebase/Editor/ for me). This file initally had "com.google.firebase:firebase-crashlytics:17.0.0" listed, which I updated to be: "com.google.firebase:firebase-crashlytics:17.1.1".
As an extra precaution, I also added created a MyProject-Dependencies.xml file, as was suggested by a user in the thread - this file also specifies version "com.google.firebase:firebase-crashlytics:17.1.1".
Next, I modified the Unity build process to use a custom mainTemplate.gradle file to specify dependencies,
rather than using the External Dependency Resolver to manage and
embed unity packages (option in Build Settings > PlayerSettings >
Android).
I also updated the settings on the External Dependency Manager Android Ressolver:
Disabled AutoResolve and Disabled Resolve on Build (we dont want EDM updating dependencies without our knowledge when building)
I also turned disabled AndroidPackageInstallationEnabled - this has made the resolution process much faster and removed a bunch of .aar files from the android dependencies list, and hasn't caused any problems in my project.
I then ran External Dependency Resolver > Android > Force Resolve, which after the settings changes above, should now embed a list of the dependencies for the Android build into the mainTemplate.gradle file - Check this file (its in Assets/Plugins/Android) and you should now see com.google.firebase:firebase-crashlytics:17.1.1 in that list.
Also, I recommend reading this article about managing Unity Firebase dependencies from one of the Firebase developer advocates, Patrick Martin. It helped me wrap my head around how Android dependency management in Unity works, as well as how the Android gradle build process works.
I work on Share Extension. And it only has a sample project (following link) and a general extension documentation.
Basic project:
Extension documentation:
When I click share with my app on iphone (for example on photos), I want to send this file to my app and upload it remote server. But I couldn't find anyway to send object from share extension. I looked up and probably I need to use "NSUserDefaults" and I tried to use it that:
I did necessary settings (creating group id, app id etc) on my apple developer account.
I did necessary settings on my project Entitlements.plist
I try to send on ShareViewController - DidSelectPost method in the my project's share extension as below:
var default = new NSUserDefaults ("group.com.myapp.AppName", NSUserDefaultsType.SuiteName);
default.SetString ("Test content", "TestKey");
default.Synchronize ();
4)I try to receive string data on my main project's AppDelegate as below:
var default = new NSUserDefaults ("group.com.myapp.AppName", NSUserDefaultsType.SuiteName);
var key = default.StringForKey ("TestKey");
string value = key;
But I couldn't do it. And I saw someone did this with OpenUrl function. I tried this and this didn't work.
I started mobile programming with Xamarin forms and I don't know enough native iOS programming (I only learn with Xamarin). I think share extension has insufficient documentation.
I would like to use Firebase analytics for one of my library modules. I would like to program in such a way that configuration file (google-services.json) should be accessible from either client app folder or configure the same from the client side.
Is there a way I could implement the above mentioned scenario?
Thanks in advance.
You can initialize your library project configurations manually as below,
For more info, kindly refer working-with-multiple-firebase-projects-in-an-android-app
Also go-through how-does-firebase-initialize-on-android to understand; how the Firebase module is getting initialized by itself.
For Android apps using Firebase, there is a central FirebaseApp object
that manages the configuration for all the Firebase APIs. This is
initialized automatically by a content provider when your app is
launched, and you typically never need to interact with it. However,
when you want to access multiple projects from a single app, you'll
need a distinct FirebaseApp to reference each one individually. It's
up to you to initialize the instances other than the default that
Firebase creates for you.
FirebaseOptions options = new FirebaseOptions.Builder()
.setApplicationId("1:530266078999:android:481c4ecf3253701e") // Required for Analytics.
.setApiKey("AIzaSyBRxOyIj5dJkKgAVPXRLYFkdZwh2Xxq51k") // Required for Auth.
.setDatabaseUrl("https://project-1765055333176374514.firebaseio.com/") // Required for RTDB.
.build();
FirebaseApp.initializeApp(this /* Context */, options, "secondary");
Hope I've answered your question.
I've found interesting workaround. Try the following:
put your google-services.json to any sample app google provides for Firebase integration. Compile it.
Take a look on path app/build/generated/res/google-services/debug/values/ there should be generated values.xml file with bunch of strings mentioned in errors you described. Copy these strings to value.xml file of your project. That's it.
Just loaded firebase 3.0 with react-native and getting the error
[fatal][tid:com.facebook.react.RCTExceptionsManagerQueue] Unhandled
JS Exception: Can't find variable: document
Is react-native supported yet?
React-native code:
var firebase = require('firebase')
// Initialize Firebase
var config = {
apiKey: '<apiKey>',
authDomain: '<app>.firebaseapp.com',
databaseURL: 'https://<app>.firebaseio.com',
storageBucket: 'firebase-<app>.appspot.com'
};
firebase.config(config)
The newest version of firebase uses the document variables that are used in web applications and the RCTWebSocket or RCTView doesn't work the same way. (I'm not 100% sure about all the details). Anyway, you can just install an older version of firebase and it will work for you. Assuming you have npm installed follow these instructions.
Uninstall Firebase from your react-native project npm uninstall firebase --save
Install version 2.4.2 of firebase npm install firebase#2.4.2 --save
Happy Firebaseing!
Firebase JS SDK 3.1 just got released and is now compatible with React Native!
See release notes.
I was able to get Firebase 3.0.2 to load in React Native by putting the following in a .js file and importing it at the top of index.ios.js:
global.location = {
href: ''
};
global.screen = {
};
global.document = {
getElementsByTagName: function(){}
};
global.parent = global;
There may be other gotchas - I have not explored further than this but it might get Firebase 3 working for you.
Firebase 3.x is not supported in RN (yet..).
Issue
I think the issue relates to the auth module's dependency on the browser's window variable.
Will it be officially supported?
According to the following discussion thread from the Firebase team, they are presently working on 3.x support. There is however no release time frame set.
Google Groups Discussion.
Workarounds
Option 1 (with FB 2.x)
From Jacob Wenger:
If React Native support is a blocker for you, please continue to use
the 2.x.x SDKs until we resolve this issue. The 2.x.x SDKs will
continue to work, even after you migrate to the new console..`
Option 2 (with FB 3.x)
From Jacob Wenger:
As a "workaround" if you don't need auth (unlikely, I know, but still
worth mentioning), you should be able to do the following:
var app = require('firebase/app');
var database = require('firebase/database');
To use last version of Firebase with ReactNative you can use Firebase Bridge.
I have a demo app here.
Whilst the Firebase JS SDK does work on react native now, it is mainly built for the web and is generally not the best solution for react-native.
The Firebase Web SDK runs entirely on react native's JS thread, therefore affecting your application frame rate (the link explains this well).
In my tests, the native firebase SDK's has been roughly 2-3 times quicker than using the web SDK.
But on top of the potential performance impacts there's a lot of features you'll be unable to use with the web SDK on android/ios devices. For example:
Notifications / FCM
Offline capabilities
Storage upload/download
Firebase Crash Reporting
Analytics
Use of social authentication providers
The best approach would be to run with the native android/ios firebase sdk's and have a bridge between them and your js code (i.e. a native module setup).
Thankfully you don't have to implement this yourself, there's already modules out there to do this for you:
react-native-firebase for example mirrors the the web sdk's api js side but executes on the native side using the native android & ios firebase sdk's. It's fully compatible with any existing firebase js logic that you may have already implemented and is intended as a drop in replacement for the web sdk.
