OAuth 2.0 authentication for RADAR-pRMT

Plugin that contains a LoginManager that can handle OAuth 2.0 authentication using the Authorization Code Grant flow. See the source in src/main/java/org/radarbase/android/auth/oauth2/OAuth2LoginManager for more information.

Installation

To add the plugin code to your app, add the following snippet to your app's build.gradle file.

dependencies {
    implementation "org.radarbase:radar-android-login-oauth2:$radarCommonsAndroidVersion"
}

Configuration

The following Firebase parameters are available:

Parameter	Type	Default	Description
oauth2_authorize_url	string	<none>	OAuth 2.0 authorization code URL
oauth2_token_url	string	<none>	OAuth 2.0 token URL
oauth2_redirect_url	string	<none>	URL to refer back to. This must be a URL registered to be used by your app.
oauth2_client_id	string	<none>	Client ID for the OAuth 2.0 server.

In addition to these requirements, add a setting to build.gradle:

android.defaultConfig.manifestPlaceholders = [
  'appAuthRedirectScheme': 'com.example.app'
]

This redirect scheme must be unique to your app, and match the prefix of the oauth2_redirect_url setting. For the above example, oauth2_redirect_url could be com.example.app://oauth2/callback.
