My Android application uses Java OAuth library, found here for authorization on Twitter. I am able
to get a request token, authorize the token and get an acknowlegement but when the browser tries the call
back url
to reconnect with my application, it does not use the URL I provide in code, but uses the one I supplied while registering with Twitter.
Note:
1. When registering my application with twitter, I provided a hypothetical call
back url:http://abz.xyc.com and set the application type as browser.
2. I provided a callback url in my code "myapp" and have added an intent filter for my activity with Browsable category and data scheme as "myapp".
3. URL called when authorizing does contain te callback url, I specified in code.
Any idea what I am doing wrong here?
Relevant Code:
public class FirstActivity extends Activity
{
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
OAuthAccessor client = defaultClient();
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(client.consumer.serviceProvider.userAuthorizationURL + "?oauth_token="
+ client.requestToken + "&oauth_callback=" + client.consumer.callbackURL));
startActivity(i);
}
OAuthServiceProvider defaultProvider()
{
return new OAuthServiceProvider(GeneralRuntimeConstants.request_token_URL,
GeneralRuntimeConstants.authorize_url, GeneralRuntimeConstants.access_token_url);
}
OAuthAccessor defaultClient()
{
String callbackUrl = "myapp:///";
OAuthServiceProvider provider = defaultProvider();
OAuthConsumer consumer = new OAuthConsumer(callbackUrl,
GeneralRuntimeConstants.consumer_key, GeneralRuntimeConstants.consumer_secret,
provider);
OAuthAccessor accessor = new OAuthAccessor(consumer);
OAuthClient client = new OAuthClient(new HttpClient4());
try
{
client.getRequestToken(accessor);
} catch (Exception e)
{
e.printStackTrace();
}
return accessor;
}
@Override
protected void onResume()
{
// TODO Auto-generated method stub
super.onResume();
Uri uri = this.getIntent().getData();
if (uri != null)
{
String access_token = uri.getQueryParameter("oauth_token");
}
}
}
// Manifest file
