因此，我正在尝试OAuth使用该Twitter4J库来解决这个问题。

我会介绍一点背景。

我在我的AndroidManifest.xml.

我有一个完全处理我的推特身份验证的活动。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    //set up the datahelper
    dh = new DataHelper(this, null);
    tae = dh.GetAuthenticationObject();
    setContentView(R.layout.main);
}

@Override
protected void onResume() {
    super.onResume();
    selectOption(getIntent());
}

public void selectOption(Intent intent) {
    Uri uri = intent.getData();
    if (uri != null && uri.toString().startsWith(CALLBACKURL) && tae.hasBeenAuthenticatedTwitter()) {           
        completeAuth(intent);           
    } else {
        doOauth();
    }
}

private void doOauth() {
    try {
        consumer = new CommonsHttpOAuthConsumer(Enums.TWITTER_APPLICATION_KEY,
                Enums.TWITTER_APPLICATION_SECTRET);

        provider = new DefaultOAuthProvider(
                Enums.TWITTER_REQUEST_TOKEN_URL,
                Enums.TWITTER_ACCESS_TOKEN_URL,
                Enums.TWITTER_AUTHORIZE_URL);

        String authUrl = provider.retrieveRequestToken(
                consumer, CALLBACKURL);

        tae.TwitterToken =  consumer.getToken();
        tae.TwitterTokenSecret = consumer.getTokenSecret();
        dh.SaveAuthenticationObject(tae);

        this.startActivity(new Intent(Intent.ACTION_VIEW, Uri
                .parse(authUrl)));
    } catch (Exception e) {
        Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
    }
}

/**
 * After use authorizes this is the function where we get back callbac with
 * user specific token and secret token. You might want to store this token
 * for future use.
 */

public void completeAuth(Intent intent) {
    Uri uri = intent.getData();
    if (uri != null && uri.toString().startsWith(CALLBACKURL)) {

        tae = dh.GetAuthenticationObject();
        String verifier = uri
                .getQueryParameter(oauth.signpost.OAuth.OAUTH_VERIFIER);
        tae.TwitterVerifier = verifier;
        dh.SaveAuthenticationObject(tae);   
    }

    Intent settingsIntent = new Intent(this, com.undetowdevelopment.kontakt.Settings.class);
    settingsIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
    settingsIntent.putExtra("REQUEST_CODE", Enums.REQUEST_CODE_TWITTER_LOGIN);
    settingsIntent.putExtra("RESULT_CODE", Activity.RESULT_OK);
    startActivity(settingsIntent);  
}

这门课完全符合我的预期。它会打开 Twitter 身份验证页面，返回活动并将其保存Token & Secret到我的共享首选项中。

我的AndroidManifest.xml样子：

    <activity android:name=".TwitterSuccess" android:label="@string/app_name" android:launchMode="singleTop">
        <intent-filter>
            <action android:name="android.intent.action.VIEW"></action>
            <category android:name="android.intent.category.DEFAULT"></category>
            <category android:name="android.intent.category.BROWSABLE"></category>
            <data android:scheme="myapp" android:host="mainactivity"/>
        </intent-filter>
    </activity>

但是，当我的应用程序启动时，我想检查此人是否已通过身份验证，而不必一直要求用户再次进行身份验证。

从我的所有活动中，我有一个方法返回一个 Twitter 对象，我想用它来设置状态或获取用户的朋友。

我使用以下方法来做到这一点：

public Twitter getTwitterObject()
{

    AuthenticationEntity ae = GetAuthenticationObject();

    CommonsHttpOAuthConsumer consumer = new CommonsHttpOAuthConsumer(Enums.TWITTER_APPLICATION_KEY, Enums.TWITTER_APPLICATION_SECTRET); 
    //Set the requestToken and the tokenSecret that you got earlier by calling retrieveRequestToken.
    consumer.setTokenWithSecret(ae.TwitterToken, ae.TwitterTokenSecret);

    //The provider object is lost, too, so instantiate it again.
    DefaultOAuthProvider provider = new DefaultOAuthProvider(
            Enums.TWITTER_REQUEST_TOKEN_URL,
            Enums.TWITTER_ACCESS_TOKEN_URL,
            Enums.TWITTER_AUTHORIZE_URL);

    //Now that's really important. Because you don't perform the retrieveRequestToken method at this moment, the OAuth method is not detected automatically (there is no communication with Twitter). So, the default is 1.0 which is wrong because the initial request was performed with 1.0a.
    provider.setOAuth10a(true);


    try {
        provider.retrieveAccessToken(consumer, ae.TwitterVerifier);
    } catch (Exception e) {
        Toast.makeText(mContext, e.getMessage(), Toast.LENGTH_LONG).show();
        e.printStackTrace();
    }

    Twitter twitter = new TwitterFactory().getInstance();
    twitter.setOAuthConsumer(Enums.TWITTER_APPLICATION_KEY, Enums.TWITTER_APPLICATION_SECTRET);
    twitter.setOAuthAccessToken(new AccessToken(consumer.getToken(), consumer.getTokenSecret()));
    return twitter;

}

现在，如果用户刚刚登录，这可以正常工作，但是如果我再次启动应用程序（这无关紧要，因为我只使用来自静态变量和共享首选项的数据），我无法进行身份验证，并且出现以下异常：

就像我提到的，当我刚刚完成身份验证时，一切正常，但是如果我再次启动我的应用程序，我会收到此消息。

我正在使用HTC Incredible运行 Android 2.2 的 . 该应用程序正在为 Android 1.6+ 开发。

任何意见或帮助将不胜感激！

最好的，

伊格努斯

我不太确定你在做什么，但你可以看看 Zwitscher https://github.com/pilhuhn/ZwitscherA，尤其是在https://github.com/pilhuhn/ZwitscherA/blob/v065/src /de/bsd/zwitscher/LoginActivity.java方法，然后调用 TwitterHelper。

当用户第一次登录并且从未登录时，活动会检查这一点并显示一个带有“getPinFromTwitter”按钮的屏幕 - 这会将用户重定向到他可以登录并获取 pin 的 twitter。用户再次启动应用程序，输入 pin 并单击“setPin”。在此版本的 Zwitscher 中，帐户存储在数据库中；在早期版本中（例如，只需查看 v065 标签：https ://github.com/pilhuhn/ZwitscherA/tree/v065 ），这是通过共享首选项完成的。来源目前有点不稳定。
