I m trying to tweet image from sd card folder but still can't do that. I m using twitter4j-core-3.0.3 api and gave permissions android.permission.INTERNET,android.permission.ACCESS_NETWORK_STATE. Here is my code

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);


    mSharedPreferences = getApplicationContext().getSharedPreferences(
            "MyPref", 0);

    twitterButton = (Button) findViewById(R.id.twitPic);

    twitterButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) 
        {
            new ImageSender().execute();

        }
    });

    if (!isTwitterLoggedInAlready()) {
        Uri uri = getIntent().getData();

编辑：：当我试图在这部分鸣叫文本

When i try to tweet a text in this portion

StatusUpdate status = new StatusUpdate("");
status.setMedia(targetDirector);
twitter.updateStatus(status);

到 twitter.updateStatus（如果你在Twitter上阅读，它的工作！）; 然后同样的错误创建

to twitter.updateStatus("If you're reading this on Twitter, it worked!"); then same error creates.

我为它的一些天，但没有得到解决方案。请人帮我解决了problem.Thanks

I m on it from some days but get no solution. Please anyone help me to solve the problem.Thanks

推荐答案

改变你的的AsyncTask 这样使用它为我工作。

change you AsyncTask use like this it is working for me

 twitterButton.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) 
    {
        String status = null;   
    new updateTwitterStatus().execute(status);

    }
}); 

public class updateTwitterStatus extends AsyncTask<String, String, String> {         
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        ProgressBar_show();
    }

    protected String doInBackground(String... args) {

        try {
            ConfigurationBuilder builder = new ConfigurationBuilder();
            builder.setOAuthConsumerKey(TWITTER_CONSUMER_KEY);
            builder.setOAuthConsumerSecret(TWITTER_CONSUMER_SECRET);

            // Access Token
            access_token = SharedPreferences.getString(PREF_KEY_OAUTH_TOKEN, "");
            // Access Token Secret
            access_token_secret = SharedPreferences.getString(PREF_KEY_OAUTH_SECRET, "");            

            String upload_image_url = postPicture( "/mnt/sdcard/yourimage.jpg", " ");
            Log.d("--------------upload_image_url=" + upload_image_url.toString() + "---------", " ");

        } catch (Exception e) {              
            Log.d("Twitter Update Error", e.getMessage());
        }
        return null;
    }

    public String postPicture(String fileName, String message) {

        try {
            Log.d("----start---postPicture()---", " ");
            File file = new File(fileName);
            MediaProvider mProvider = getMediaProvider();

            String accessTokenToken = access_token;
            String accessTokenSecret = access_token_secret;

            Properties props = new Properties();
            props.put(PropertyConfiguration.MEDIA_PROVIDER, mProvider);

            Configuration conf = new PropertyConfiguration(props);

            ImageUploadFactory factory = new ImageUploadFactory(conf);
            ImageUpload upload = factory.getInstance(mProvider);
            String url;
            url = upload.upload(file, message);
            Log.d("----end---postPicture()---", " ");
            return url;
        } catch (Exception e) {

            mProvider = MediaProvider.TWITTER;
        else
            throw new IllegalArgumentException("Picture provider " + provider + " unknown");

        Log.d("----end---getMediaProvider()---", " ");

        return mProvider;
    }

    protected void onPostExecute(String file_url) {
        ProgressBar_hide();
        // updating UI from Background Thread
        runOnUiThread(new Runnable() {
            public void run() {
                Toast.makeText(getApplicationContext(), "Status tweeted successfully", Toast.LENGTH_SHORT).show();
