I'm trying to integrate
Yahoo into my application. I want them to login using their
Yahoo accounts because I will be needing their names later in the application. But whenever I request for a token, I receive the following errors:
getRequestToken() Exception: oauth.signpost.exception.OAuthCommunicationException:
Communication with the service provider failed: Service provider responded in error: 400 (Bad Request)
Here is my code (Request_Token_Activity.java):
import oauth.signpost.OAuth;
import oauth.signpost.OAuthConsumer;
import oauth.signpost.OAuthProvider;
import oauth.signpost.commonshttp.CommonsHttpOAuthConsumer;
import oauth.signpost.commonshttp.CommonsHttpOAuthProvider;
import oauth.signpost.signature.HmacSha1MessageSigner;
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.net.Uri;
import android.os.Bundle;
import android.preference.PreferenceManager;
import android.util.Log;
public class Request_Token_Activity extends Activity {
private OAuthConsumer consumer;
private OAuthProvider provider;
private SharedPreferences prefs;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
consumer = new CommonsHttpOAuthConsumer("my consumer key", "my consumer secret");
consumer.setMessageSigner(new HmacSha1MessageSigner());
provider = new CommonsHttpOAuthProvider(
"http://api.login.
yahoo.com/oauth/v2/get_request_token",
"http://api.login.
yahoo.com/oauth/v2/get_token",
"http://api.login.
yahoo.com/oauth/v2/request_auth");
} catch (Exception e) {
Log.e("", "onCreate Exception: " + e.toString());
}
getRequestToken();
}
private void getRequestToken() {
try {
String url = provider.retrieveRequestToken(consumer, "yahooapi://callback");
Log.i("", "
Yahoo URL: " + url);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url)).setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_FROM_BACKGROUND);
this.startActivity(intent);
} catch (Exception e) {
Log.i("", "getRequestToken() Exception: " + e.toString());
}
}
@Override
public void onNewIntent(Intent intent) {
super.onNewIntent(intent);
prefs = PreferenceManager.getDefaultSharedPreferences(this);
final Uri uri = intent.getData();
if (uri != null && uri.getScheme().equals("yahooapi")) {
getAccessToken(uri);
}
}
private void getAccessToken(Uri uri) {
final String oauth_verifier = uri.getQueryParameter(OAuth.OAUTH_VERIFIER);
try {
provider.retrieveAccessToken(consumer, oauth_verifier);
final Editor edit = prefs.edit();
edit.putString("YAHOO_OAUTH_TOKEN", consumer.getToken());
edit.putString("YAHOO_OAUTH_TOKEN_SECRET", consumer.getTokenSecret());
edit.commit();
String token = prefs.getString("YAHOO_OAUTH_TOKEN", "");
String secret = prefs.getString("YAHOO_OAUTH_TOKEN_SECRET", "");
consumer.setTokenWithSecret(token, secret);
Log.i("", "
Yahoo OAuth Token: " + token);
Log.i("", "
Yahoo OAuth Token Secret: " + token);
} catch (Exception e) {
Log.i("", "getAccessToken Exception: " + e.toString());
}
}
}
And this is a snapshot of my AndroidManifest.xml:
<activity android:name="Request_Token_Activity" android:launchMode="singleTask">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="yahooapi" android:host="callback" />
</intent-filter>
</activity>
I have set-up my
Yahoo Project as a Web Application and put Read and Write access to Social and
Contacts. What am I doing wrong?
