Cannot resolve symbol default_web_client_id in Firebase's Android Codelab

Question

I am trying to learn Firebase, so I went through the Android Codelab. The project they gave me however, had an error:

Cannot resolve symbol default_web_client_id

And I didn't know how to solve it, since I didn't know the value of default_web_client_id or what it is. It is in the onCreate() method: SigninActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_sign_in);
    mFirebaseAuth = FirebaseAuth.getInstance();

    // Assign fields
    mSignInButton = (SignInButton) findViewById(R.id.sign_in_button);

    // Set click listeners
    mSignInButton.setOnClickListener(this);

    // Configure Google Sign In
    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken(getString(R.string.default_web_client_id))
            .requestEmail()
            .build();
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();
}

I have no idea what it is, what's its value is, and why is it giving me this error. I haven't changed anything so far except for adding the google-services.json. I have added my SHA-1 and enabled Google in the console.

you have to register to the Auth 2.0 from developer.google.com. use this: console.developers.google.com/apis/credentials?project=_ to generate a Auth 2.0 key – Pushkin

@M.WaqasPervez I have already added my SHA1 key, is Auth2.0 different? – Amhara

Can you make sure that you have this line apply plugin: 'com.google.gms.google-services' at the bottom of your app/build.gradle, as documented here? – Burgonet

Answer 1

Sometimes there is issue while parsing google-services.json. I have reported this issue with to concerned team.

Meanwhile follow below step to fix this issue to get going further -

1) Open google-services.json file -> client -> oauth_client -> client_id

2) Copy this client ID and hardcode this .requestIdToken("your ID")

It would allow to request "IdToken" via GoogleSignInAccount post successful google login and to authorize your credential with firebase.

EDIT

Try deleting and recreating the project and re-importing new google-service.jsonin your Android project

Matchbox

This is what I see in oauth_client: "oauth_client": [] there is no ID, and I can't find client_id anywhere in the file either. – Amhara

@AbAppletic try adding SHA1 key and re-downloading the config file from firebase console - project setting – Matchbox

Still nothing. I have added my SHA1 – Amhara

@AbAppletic if you have just started with the project. try deleting and re-creating a new project -> add android app. This should work. Even if does not work try contacting firebase team. – Matchbox

Thanks, it worked. Deleting the app then remaking it fixed the problem from the beginning, didn't have to hardcode anything. – Amhara

What if you have more than 1 client ids? I just looked at my project just now. There is one for client type 1 and client type 3. What does these mean? – Fancywork

This isn't quite right. You need to make sure client_type is 3. See my answer. – Monopetalous

Answer 2

A more generic solution would be to add the google-services.json into the app's root directory.
And add

apply plugin: 'com.google.gms.google-services at the end of build.gradle file.

Explanation

When the app builds the key value pair strings from google-services.json config file are then placed into the values.xml file to make them globally available for use from anywhere in your code. This saves us from hard coding the client_id in your code.

Note

Do not add the default_web_client_id with client_id as its value in the strings.xml in order to avoid the error of duplication, Error: Duplicate resourceslater on when you run your code.

Woolgathering

build worked after making this update and then running invalidate cache & restart. much nicer than having to edit the .json file - thanks – Sedation

Did not work in my case. I am using Android Studio 4.1 – Underhanded

Answer 3

1. google-services.json in ./app/ folder
2. Add in project-level build.gradle the following:

    buildscript {
    ...
    dependencies {
        ...
        classpath 'com.google.gms:google-services:4.3.5'
    }

3. In app-level build.gradle, apply the plugin:

    apply plugin: 'com.google.gms.google-services'

This is the annoying thing I found. Upgrading it from 4.3.5 to anything higher than that makes Android Studio unable to detect the generated values.xml file.

Pheni

Same com.google.gms:google-services:4.3.10 not working ,so I implemented 4.3.5 – Renaterenato

Damn, this really works. My build didn't fail by that error so I was ignoring it all along thinking its a glitch somewhere. – Septic

Answer 4

After a time searching the "smart" fix without insert directly the client_id, following this answer from FirebaseUI project I just need to add the next line in app/build.gradle:

implementation 'com.firebaseui:firebase-ui-auth:4.3.2'

Nolin

That helps to resolve an error during build. However, yet it does not automatically put ID from json file to values.xml... So it works but does not login :( – Gilthead

Yes it worked for me, thank you so much and it's better than just insert the client_id directly – Contort

still there. in 2023. Google is amazing in hardliving. – Diorama

Answer 5

Apparently R.string.default_web_client_id is generated from the IDE build

I had assumed we are supposed to manually add it - time consuming mistake

https://developers.google.com/android/guides/google-services-plugin

The google-services plugin has two main functions: 1) Process the google-services.json file and produce Android resources that can be used in your application's code.

~~~~

The main result of the JSON processing is to produce two XML files which you can reference as Android resources in your Java code.

And so - after successful build, if you search the IDE for string default_web_client_id , you will see one result is values.xml under the /generated folder, and there it has the values for your firebase config, like the example below.

Actually seeing that file, helped to clarify things here

<resources>
    <string name="default_web_client_id" translatable="false">123.apps.googleusercontent.com</string>
    <string name="firebase_database_url" translatable="false">https://123.firebaseio.com</string>
    <string name="gcm_defaultSenderId" translatable="false">123</string>
    <string name="google_api_key" translatable="false">123</string>
    <string name="google_app_id" translatable="false">123</string>
</resources>

This is solution to my problem, I just did rebuild of project & it worked. – Predecease

Answer 6

**The main issue with this right now for me was to make sure to download the json file from the same location. If the initial one came from the firebase console do not use the api console to get the file, and vise versa. The files are not the same **

Schecter

Thanks for your comment. I just tried to google download json file from API, but for now all the links refer to download page of Firebase :( – Gilthead

sorry to hear that, but it kind of depends where the original file came from. if the project was originally a firebase project then use that file. if the project came from the api console download and use that file. Don't mix them. At the time of this post that was true. Unfortunately it is a moving target. – Schecter

Well anyway for now I hardcoded the web id, at least it works, even though hardcoded – Gilthead

also sent an issue to firebase, they didn't respond at all - so in the future I would move all the backend from firebase to something more reliable – Gilthead

Answer 7

I already have google-services.json downloaded and parsed, but still it doesn't find the string.

I noticed that my oauth_client had a key with client_type of 1 and that's all. In the Google API console, I only had an Android key.

So, you need to go to the API console and generate a Web Server key. Then, download your google-services.json again, and you'll have a oauth_client with a type of 3.

Now, the plugin will generate a string called default_web_client_id.

Monopetalous

Answer 8

I had the same problem or similar,

Make sure that in your google-services.json you have:

...    
"client": [
        ...
          "oauth_client": [
            ...
            {
              "client_id": "YOUR WEB CLIENT ID",
              "client_type": 3
            }     
...

For some reason the file downloaded from firebase console doesn't include it.

After adding the entry in the google-services.json file, everything started working as expected.

Answer 9

Download your newest google-services.json. List of client_id is present for OAuth 2.0 client IDs in your Google Cloud Credentials.

Then check whether it contains client_id with "client_type" : 3 or not. If not, you need to create a new one:

1. Open the Credentials page in the API Console.
2. Click Create credentials -> OAuth cliend ID. Then chose type Web application.
3. Wait 2-3 minutes, refresh Firebase Console & download your google-services.json again. It should contain client_id with "client_type" : 3 now.

Clean & rebuild your project to apply new API config.

---

The client_id with "client_type" : 3 is usually inside oauth_client tag, not services or other_platform_oauth_client.

If you fall to this case & cannot build the project, try copy your client_id to oauth_client tag and rebuild again.

"client": [
        ...
        "oauth_client": [
            ...
            {
              "client_id": "YOUR WEB CLIENT ID",
              "client_type": 3
            }
        ]
]

Answer 10

In addition to the Dexto's Answer I would like to mention one more thing In the JSON file you will get two kind of client id

One Which is having client_type value 1 and Another with the client_type value 3 Make sure you specified the client_id of client_type which has value of 3

Answer 11

classpath 'com.google.gms:google-services:4.1.0'

has a problem. instead use:

classpath 'com.google.gms:google-services:4.2.0'

Poorly

Answer 12

I also had the same issue, make sure "google-services.json" is in your app directory. Then simply rebuild the project from "Build -> Rebuild Project"

Since the string resource "default_web_client_id" is auto-generated, it will be resolved once you rebuild the project

Answer 13

for my case: The lib was old so I go get the last lib at: https://firebase.google.com/docs/auth/android/firebaseui

put in dependency: implementation 'com.firebaseui:firebase-ui-auth:7.2.0'

along with what currently there

// Import the BoM for the Firebase platform implementation platform('com.google.firebase:firebase-bom:26.7.0')

// When using the BoM, you don't specify versions in Firebase library dependencies implementation 'com.google.firebase:firebase-auth-ktx'

and it is fixed

Prudenceprudent

Not fixed for me. – Procora

Answer 14

Try downloading your .json file again after changing the configuration in the Firebase console. Use this newer configuration file, not the old one.

Hols

Answer 15

Fixed after using this link to create my backend id to Google API.

https://developers.google.com/identity/sign-in/android/start-integrating#get_your_backend_servers_oauth_20_client_id

• 1- Open the Credentials page in the API Console.

• 2- The Web application type client ID is your backend server's OAuth 2.0 client ID.

After this, you can re-download your json file and android studio will automatically matching your string id.

Answer 16

I know it is late to answer but hope this will help someone in the future.

To access there is no need to hard code default_web_client_id in app.

To access default_web_client_id in Android App from google-services.json, we have to add SHA1 key under FireBase project Settings.

Go to Firebase Console > Open Project > Select App > Add Fingerprint.

After this copy generated google-services.json to project.

After this you will see the difference in json file as below:

Before :

"oauth_client": []

After :

"oauth_client": [
    {
      "client_id": "23........4-asdj...........................asda.googleusercontent.com",
      "client_type": 1,
      "android_info": {
        "package_name": "com.abc.xyz",
        "certificate_hash": "asjhdashhs"
      }
    },.....

This will solve your issue.

Generic solution for this is to apply google play services plugin at the end of build.gradle like this

  apply plugin: 'com.android.application'

    compileSdkVersion 30
    buildToolsVersion "30.0.0"

    buildFeatures {

Answer 19

Use BOM to use the compatible version of firebase.

In your module (app-level) Gradle file:

dependencies {
  // ...

  // Import the Firebase BoM
  implementation platform('com.google.firebase:firebase-bom:29.3.0')

  // When using the BoM, you don't specify versions in Firebase library dependencies

  // Declare the dependency for the Firebase SDK for Google Analytics
  implementation 'com.google.firebase:firebase-analytics'

  // Declare the dependencies for any other desired Firebase products
  // For example, declare the dependencies for Firebase Authentication and Cloud Firestore
  implementation 'com.google.firebase:firebase-auth'
  implementation 'com.google.firebase:firebase-firestore'
}

Answer 20

What I have done is just Rebuild the project and that works for me.

Yes I have checked before doing that my google-services.json file is on the proper place and it is having client_type = 3 as key and client_id = "Your Client Id" as well.

Consider here "Your Client Id" = Your app's client ID which you will get from the firebase.

Answer 21

In my case, google-services.json file "client" -> "oauth_client" -> has no details.

"oauth_client": [
    { 
    }

],

Therefore I download google-services.json file from my Firebase Project Settings and replace the file in my project.

Answer 22

I see some workarounds here, Root cause: When we create the firebase project and download the google-services.json file, firebase authentication is not enabled and thus google-services.json won't contain oauth id'

Correct solution:

1. Enable GoogleAuthentication in Firebase as shown in image below:

2. Download google-services.json again.
