    <p>I have an Android application with GAE server. I tried to authenticate the user as described on developers.google.com, I added the user parameter to the endpoint methods etc. I get a User which is not null, but this method getUserId() returns null. It is similar to this, rather old problem: <a href="https://stackoverflow.com/questions/16171225/function-user-getuserid-in-cloud-endpoint-api-returns-null-for-a-user-object-t">Function User.getUserId() in Cloud endpoint api returns null for a user object that is not null</a> But I still don't know how to work around it. How do you handle this error? Have you ever encountered it?</p> <p>In android client here's what I did (its simplified) :</p> <pre><code>credentials = GoogleAccountCredential.usingAudience(getApplicationContext(), "server:client_id:" + WEB_CLIENT_ID); credentials.setSelectedAccountName(accountName); WarriorEntityEndpoint.Builder endpointBuilder = new WarriorEntityEndpoint.Builder(AndroidHttp.newCompatibleTransport(), new GsonFactory(), credentials); warriorEntityEndpoint = endpointBuilder.build(); new AsyncTask&lt;Void, Void, Void&gt;() { @Override protected Void doInBackground(Void... params) { // TODO Auto-generated method stub try { warriorEntityEndpoint.getWarrior().execute(); } catch (Exception e) { } return null; } }.execute(); </code></pre> <p>And on GAE:</p> <pre><code>@Api(name = "warriorEntityEndpoint", namespace = @ApiNamespace(ownerDomain = "szpyt.com", ownerName = "szpyt.com", packagePath = "mmorpg.monsters"), version = "version1", scopes = {"https://www.googleapis.com/auth/userinfo.email", "https://www.googleapis.com/auth/userinfo.profile"}, clientIds = {Constants.ANDROID_CLIENT_ID, Constants.WEB_CLIENT_ID}, audiences = {Constants.ANDROID_AUDIENCE}) public class WarriorEntityEndpoint { private static final Logger log = Logger.getLogger(WarriorEntityEndpoint.class.getName()); @ApiMethod(name = "getWarrior") public WarriorEntity getWarrior(User user) throws OAuthRequestException, IOException { log.log(Level.SEVERE, "this gives correct email: " + user.getEmail()); log.log(Level.SEVERE, "this is null: " + user.getUserId()); </code></pre> <p>I have also another very important question: is this user authenticated, if getMail() gives me correct account, but getUserId() gives null? I read that user object should be null if it was not authenticated but I am not sure any more... I'm using App engine SDK 1.8.7. I'm testing on a real device and backend deployed to GAE.</p>

    2. COSure, but I'll submit my code around 4pm, when I get back home. I thought I'll ask now when I am at work and maybe when I get back home I'll have the answer and be able to progress with my own project... Although I belive I followed this: https://developers.google.com/appengine/docs/java/endpoints/consume_android#making-authenticated-calls and that: https://developers.google.com/appengine/docs/java/endpoints/auth prety literally...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
