  1. POAndroid: how do I authenticate to my google account and how can I get my GMail Tasks?
    text
    copied!<p>I am developing an Android app to connect to my Google Tasks and show them in a ListView. I tried to follow step by step some tutorial such as <a href="https://developers.google.com/google-apps/tasks/oauth-and-tasks-on-android" rel="nofollow">https://developers.google.com/google-apps/tasks/oauth-and-tasks-on-android</a> but none of those works. I tried to download the google-api-services-tasks-v1-1.1.0-beta.jar and all the jars inicated in that tutorial, and after importing all the necessary libraries it just didn't work, and when i try to get my tasks after the connection i just get nulls.</p> <p>I found out that i could use Oauth2.0 for the authentication and to access to the tasks API, to get my clientID ecc., so i created an account on the Google API's Console and created my OAuth clientID.</p> <p>After that I try to authenticate with this code</p> <pre><code>HttpTransport transport = new NetHttpTransport(); JacksonFactory jsonFactory = new JacksonFactory(); String clientId = "myID"; String clientSecret = "mySecret"; String redirectUrl = "https://localhost/oauth2callback"; Iterable&lt;String&gt; scope ="https://www.googleapis.com/auth/tasks"; String authorizationUrl = new GoogleAuthorizationCodeRequestUrl(clientId, redirectUrl, scope) .build(); String code="Code"; GoogleTokenResponse response = new GoogleAuthorizationCodeTokenRequest(transport, jsonFactory, clientId, clientSecret, code, redirectUrl).execute(); GoogleAccessProtectedResource accessProtectedResource = new GoogleAccessProtectedResource( response.getAccessToken(), transport, jsonFactory, clientId, clientSecret, response.getRefreshToken()); Tasks service = new Tasks(transport, jsonFactory, accessProtectedResource); AccessProtectedResource accessProtectedResource = new GoogleAccessProtectedResource(accessToken); Tasks service = new Tasks(transport, new JacksonFactory(), accessProtectedResource); service.accessKey="MyKey"; service.setApplicationName("GTasks"); </code></pre> <p>I don't get any error but after creating this service I tried to get my tasklists but nothing happened and i didn't get any result. When I tried to Log the content of the List of tasklists i just got an empty list "{}". I suspect that this could be because of the old version of the libraries that i found, but even when i tried to use the latest versions it didn't work and i got the same results. I'm really confused.</p> <p>Every tutorial I found recommends a different version of the libraries and a different strategy. I really don't know wich one should I follow.</p>
