Android Authentication

The userIdentifier parameter should be used to identify users to the Integration server, which should return a different access token for each user

val tokenProvider = TokenProvider.fromLambda { oldAuthToken, userIdentifier, listener ->
    // The Sensibill SDK calls this method when a new token is required.
    // Provide new valid token for user matching userIdentifier
    MyIntegrationServer.fetchNewAccessToken(object : IntegrationServerListener {
        override fun onNewAccessTokenRetrieved(newAccessToken: String?) {
            if (!newAccessToken.isNullOrEmpty()) {
                // Pass new access token to SDK via the `onTokenProvided` method
                listener.onTokenProvided(newAccessToken)
            } else {
                // If unable to provide new access token, call the `onFailed` method
                listener.onFailed("Couldn't retrieve new token!")
            }
        }
    })
}

final TokenProvider tokenProvider = new TokenProvider() {
    @Override
    public void provideTokenReplacement(@Nullable String oldAuthToken, @NotNull String userIdentifier, @NotNull TokenProvider.OnTokenProviderListener listener) {
        // The Sensibill SDK calls this method when a new token is required.
        // Provide new valid token for user matching userIdentifier.
        MyIntegrationServer.fetchNewAccessToken(new IntegrationServerListener() {
            @Override
            public void onNewAccessTokenRetrieved(String newAccessToken) {
                if (newAccessToken != null && !newAccessToken.isEmpty()) {
                    // Pass new access token to SDK via the `onTokenProvided` method
                    listener.onTokenProvided(newAccessToken);
                } else {
                    // If unable to provide new access token, call the `onFailed` method
                    listener.onFailed("Couldn't retrieve new token!");
                }
            }
