react native app auth google oauth redirect url

Question

I'm trying to use FormidableLabs/react-native-app-auth in my react native android app. I have created google oauth client id in google developer console as a web application. I have a problem adding correct redirect url in the console. As i have read the redirect url for android applications should look like something like this com.testapp.app:/oauth but these type of urls cannot be added in the google developer console. So how should i add it ?

AndroidManifest.xml

<intent-filter>
        <action android:name="android.intent.action.VIEW"/>
        <category android:name="android.intent.category.DEFAULT"/>
        <category android:name="android.intent.category.BROWSABLE"/>
        <data android:scheme="com.testchat.app" android:host="heybuddyapp/callback"/>
</intent-filter>

is the scheme correct or should it be changed ?

build.gradle

defaultConfig {
    ...
    manifestPlaceholders = [
        appAuthRedirectScheme: 'com.testchat.app:/heybuddyapp/callback'
    ]
}

config of react native app auth

const config = {
  issuer: 'https://accounts.google.com',
  clientId: 'ID.apps.googleusercontent.com',
  redirectUrl: 'com.testchat.app:/heybuddyapp/callback',
  scopes: [
    'openid',
    'profile'
  ],
};

How should be the redirect url in the above sections ? And how should it be on the google developer console ?

Any help would be appreciated !

For future readers.. I have figured out the answer. I was using web application in the google developer console create credentials section, but it should be Android instead. After adding the Signing-certificate fingerprint reference - react native sign apk Then you should add your package name as in the AndroidManifest.xml (example - com.testapp.app) Then in the android\app\build.gradle file add

defaultConfig {
    ...
    manifestPlaceholders = [
        appAuthRedirectScheme: 'com.testapp.app' //this line
    ]
}

And if you are usging FormidableLabs/react-native-app-auth package, config should be like this

const config = {
  issuer: 'https://accounts.google.com',
  clientId: 'ID.apps.googleusercontent.com',
  redirectUrl: 'com.testapp.app:/oauth2callback',
  scopes: [
    'openid',
    'profile'
  ],
};

And that's it !
