使用Android API发布推文

我一直在寻找一种方法来发布我的Android应用程序的推文,但我找到的所有东西都不起作用。

我必须承认Twitter的API并不是那么容易理解,但我的代码并不长,而且我看不出我的错误在哪里。

这是我的代码:

public class PartagerTwitter extends Activity {

    private CommonsHttpOAuthConsumer httpOauthConsumer;
    private OAuthProvider httpOauthprovider;
    public final static String consumerKey = XXX;
    public final static String consumerSecret = XXX;
    private final String CALLBACKURL = "myapp://twitactivity";
    private Twitter twitter;

    @Override

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        try {
            httpOauthConsumer = new CommonsHttpOAuthConsumer(consumerKey, consumerSecret);
            httpOauthprovider = new DefaultOAuthProvider("https://twitter.com/oauth/request_token",
                    "https://twitter.com/oauth/access_token",
            "https://twitter.com/oauth/authorize");
            String authUrl = httpOauthprovider.retrieveRequestToken(httpOauthConsumer, CALLBACKURL);

            this.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(authUrl)));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    protected void onNewIntent(Intent intent) {

        super.onNewIntent(intent);  
        Uri uri = intent.getData();
        Log.i("test", uri.toString());  
        if (uri != null && uri.toString().startsWith(CALLBACKURL)) {
            String verifier = uri.getQueryParameter(oauth.signpost.OAuth.OAUTH_VERIFIER);
            try {
                httpOauthprovider.retrieveAccessToken(httpOauthConsumer, verifier);     
                twitter = new TwitterFactory().getInstance();
                twitter.setOAuthConsumer(consumerKey, consumerSecret);

                RequestToken requestToken = twitter.getOAuthRequestToken(CALLBACKURL); 
                AccessToken accessToken = twitter.getOAuthAccessToken(requestToken);
                String token = accessToken.getToken(), 
                secret = accessToken.getTokenSecret();

                accessToken = new AccessToken(token,secret);
                Twitter twitter = new TwitterFactory().getOAuthAuthorizedInstance(consumerKey,consumerSecret,accessToken);
                twitter.updateStatus("My First Status Update");
            } catch (Exception e) {
                e.printStackTrace();

            }
        }
    }
}

当然,我的钥匙不是XXX。 另一个问题是,登录后是否有可能关闭Twitter窗口并将我的活动带到前台?

请查看the following blog post以获取从Android应用发布到Twitter的完整端到端指南。

它还包含Github中正在运行的Android示例。

在Twitter开发站点中创建具有读/写权限的应用程序,为您的应用程序生成访问令牌。

使用以下代码更新状态

public static void main(String[] args) {

    String CONSUMER_KEY = "YOUR_CONSUMER_KEY";
    String CONSUMER_SECRET = "YOUR_CONSUMER_SECRET";
    String ACCESS_SECRET = "YOUR_ACCESS_SECRET";
    String ACCESS_TOKEN = "YOUR_ACCESS_TOKEN";

    // Consumer
    Twitter twitter = new TwitterFactory().getInstance();
    twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);

    // Access Token
    AccessToken accessToken = null;
    accessToken = new AccessToken(ACCESS_TOKEN, ACCESS_SECRET);
    twitter.setOAuthAccessToken(accessToken);

    // Posting Status
    Status status = null;
    try {
        status = twitter.updateStatus("YOUR_STATUS");
    } catch (TwitterException e) {
        e.printStackTrace();
    }
    System.out.println("Successfully updated the status: "
            + status.getText());
}
