How to check callback_url in twitter application

Question

I have many examples for O_Auth, but no one is working properly, and I think that the only thing that is the return URL in each example, I get error 401, for example, the consumer key or signature does not match. I have already seen so many examples on 401, the only thing that concerns me is my callback.

Android app cannot connect to twitter .    Getting 401 when requesting an access token with a pointer inside android with-signpost-in-android   Android Dev - the callback URL does not work ... (0_o)

I have already seen all these examples and much more.

But still, I don’t understand if during the application form I use http://www.meomyo.com at the return URL, then I should use it in my coding as android: scheme = "?" android: "?" host = I use other callback examples

    //private static final Uri CALLBACK_URI = Uri.parse("bloa-app://twitt");
private static final Uri CALLBACK_URI = Uri.parse("twitterapp://connect");

I have a key for the user as well as a secret key, but in the case of url callback I got stuck on it. If someone wants, I can provide my consumer, as well as a secret key.

public class OAuth extends Activity {

private static final String APP =   "OAUTH";

private Twitter twitter;
private OAuthProvider provider;
private CommonsHttpOAuthConsumer consumer;

private String CONSUMER_KEY =       "Xh3o8Gh1JQnklkUnTvvA";
private String CONSUMER_SECRET =    "SCLy6yoUSth53goAsYYkoqR4ZuBoaInyJXsm5PQR11I";
private String CALLBACK_URL =       "merabharatmahan://piyush";

private TextView tweetTextView;
private Button buttonLogin;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    tweetTextView = (TextView)findViewById(R.id.tweet);
    buttonLogin = (Button)findViewById(R.id.ButtonLogin);
    buttonLogin.setOnClickListener(new OnClickListener() {  
        public void onClick(View v) {
            askOAuth();
        }
    });
}

/**
 * Open the browser and asks the user to authorize the app.
 * Afterwards, we redirect the user back here!
 */
private void askOAuth() {
    try {
        consumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
        provider = new DefaultOAuthProvider("http://twitter.com/oauth/request_token",
                                            "http://twitter.com/oauth/access_token",
                                            "http://twitter.com/oauth/authorize");
        String authUrl = provider.retrieveRequestToken(consumer, CALLBACK_URL);
        Toast.makeText(this, "Please authorize this app!", Toast.LENGTH_LONG).show();
        this.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(authUrl)));
    } catch (Exception e) {
        Log.e(APP, e.getMessage());
        Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
    }
}


/**
 * As soon as the user successfully authorized the app, we are notified
 * here. Now we need to get the verifier from the callback URL, retrieve
 * token and token_secret and feed them to twitter4j (as well as
 * consumer key and secret).
 */
@Override
protected void onNewIntent(Intent intent) {

    super.onNewIntent(intent);

    Uri uri = intent.getData();
    if (uri != null && uri.toString().startsWith(CALLBACK_URL)) {

        String verifier = uri.getQueryParameter(oauth.signpost.OAuth.OAUTH_VERIFIER);

        try {
            // this will populate token and token_secret in consumer
            provider.retrieveAccessToken(consumer, verifier);

            // TODO: you might want to store token and token_secret in you app settings!!!!!!!!
            AccessToken a = new AccessToken(consumer.getToken(), consumer.getTokenSecret());

            // initialize Twitter4J
            twitter = new TwitterFactory().getInstance();
            twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
            twitter.setOAuthAccessToken(a);

            // create a tweet
            Date d = new Date(System.currentTimeMillis());
            String tweet = "#OAuth working! " + d.toLocaleString();

            // send the tweet
            twitter.updateStatus(tweet);

            // feedback for the user...
            tweetTextView.setText(tweet);
            Toast.makeText(this, tweet, Toast.LENGTH_LONG).show();
            buttonLogin.setVisibility(Button.GONE);

        } catch (Exception e) {
            Log.e(APP, e.getMessage());
            Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
        }

    }
}

}

manifest code

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".OAuth"
              android:label="@string/app_name"
              android:launchMode="singleInstance">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <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="merabharatmahan" android:host="piyush" />
        </intent-filter>
    </activity>

</application

Now I get a message with the service provider crashing: the received authentication is zero. This is the simplest example that I set here.

Answer 1

twitterapp: // connect is your return URL.

Android manifest.xml :

<activity android:name=".auth.SocialNetworkActivity"
    android:configChanges="orientation"
        android:label="Connect SNS" 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="twitterapp" android:host="connect" />
        </intent-filter>
    </activity>

- Twitter onNewIntent() callback.

.

, twitter twitter4j.

, ... , - , , ... :

... , URL- . ? android:launchMode="singleTask", ?

, -, onNewIntent auth. - :
