Integration with Graph SDK from Java is very unclear

[diyoyo]

As someone very well stated here,
while the sample code for authentication from Android works perfectly fine, it is very unclear how to combine this with the Graph SDK, and especially the creation of the GraphServiceClient

How do we create a new instance of GraphServiceClient (Or how to get a AuhtenticationProvider like AzureIdentityAuthenticationProvider) from IAuthenticationResult or ISingleAccountPublicClientApplication or IAccount ?

Hi @diyoyo, Thanks a lot for feedback. I will consider your request and work with my team in near future to provide guidance for working MSAL in combination with Graph SDK. Thanks for your patience.

We use a BaseBearerTokenAuthenticationProvider to create a GraphServiceClient(authProvider, okHttpClient) object.
You have to substitute the "getToken()" call with your graph token - we keep ours in a cache and otherwise call aquireTokenSilent on the IMultipleAccountPublicClientApplication.

BaseBearerTokenAuthenticationProvider authProvider = new BaseBearerTokenAuthenticationProvider(new AccessTokenProvider() {
	@NonNull
	@Override
	public String getAuthorizationToken(@NonNull URI uri, Map<String, Object> additionalAuthenticationContext) {
		return getToken();
	}

	@NonNull
	@Override
	public AllowedHostsValidator getAllowedHostsValidator() {
		//list of allowed hosts from AzureIdentityAccessTokenProvider
		return new AllowedHostsValidator("graph.microsoft.com", "graph.microsoft.us", "dod-graph.microsoft.us", "graph.microsoft.de", "microsoftgraph.chinacloudapi.cn", "canary.graph.microsoft.com");
	}
});
