native Android client for Keycloak

Features

• gets the OAuth2.0 access token via the Authorization Code flow (access type: public client)
• uses Browser authentication
• stores the access token in the SharedPreferences
• checks if the stored access token is expired and periodically refreshes it (via WorkManager)
• uses Koin as the dependency injection framework
• Proguard configuration for the latest versions of RxJava2, retrofit2, okHttp3

Usage

Edit the file Config.kt according to your setup:

object Config {
    const val clientId = "myClientID"
    const val baseUrl = "https:/[KEYCLOAK-URL]/auth/realms/[REALM]/protocol/openid-connect"
    const val authenticationCodeUrl = "$baseUrl/auth"
    const val redirectUri = "maslick://oauthresponse"
}

Edit AndroidManifest.xml and add your redirectUri to the LoginActivity intent-filter:

<data android:scheme="maslick" android:host="oauthresponse"/>
