El archivo jar utilizado para este ..

Signpost-core-1.2.1.2.jar

Signpost-commonshttp4-1.2.1.1.jar

Twitter4j-core-3.0.3.jar

Twitter4j-media-support-3.0.3.jar

Este código es muy útil y he compartido la imagen en twitter con este código sólo ..

Aceptar respuesta si se encuentra útil .. gracias

prueba esto

  try { Configuration conf = new ConfigurationBuilder() .setOAuthConsumerKey(AppConstant.twitter_consumer_key) .setOAuthConsumerSecret(AppConstant.twitter_secret_key) .setOAuthAccessToken(AppConstant.twitterAccessToken.getToken()) .setOAuthAccessTokenSecret(AppConstant.twitterAccessToken.getTokenSecret()) .build(); OAuthAuthorization auth = new OAuthAuthorization (conf, conf.getOAuthConsumerKey (), conf.getOAuthConsumerSecret (), new AccessToken (conf.getOAuthAccessToken (), conf.getOAuthAccessTokenSecret ())); ImageUpload upload = ImageUpload.getTwitpicUploader (AppConstant.twitpic_api_key, auth); Log.d(TAG, "Start sending image..."); File picture = new File(AppConstant.rootFolder+File.separator+AppConstant.fileName); url = upload.upload(picture); Log.d(TAG, "Image uploaded, Twitpic url is " + url); Twitter twitter = new TwitterFactory().getOAuthAuthorizedInstance(AppConstant.twitter_consumer_key, AppConstant.twitter_secret_key, new AccessToken (AppConstant.twitterAccessToken.getToken(), AppConstant.twitterAccessToken.getTokenSecret())); if(status != null){ twitter.updateStatus(status + " "+url); }else{ twitter.updateStatus(url); } getDelegate().onRequestFinished(null); }catch (Exception e) { getDelegate().onRequestFailed(e); System.out.println("-------------------error|"+e.toString()); } 

ACTUALIZAR

Primero necesitas crear una aplicación en twitter

Aquí está el código para publicar un mensaje en twitter

  ConfigurationBuilder configurationBuilder = new ConfigurationBuilder(); configurationBuilder.setOAuthConsumerKey(context.getResources().getString(R.string.twitter_consumer_key)); configurationBuilder.setOAuthConsumerSecret(context.getResources().getString(R.string.twitter_consumer_secret)); configurationBuilder.setOAuthAccessToken(LoginActivity.getAccessToken((context))); configurationBuilder.setOAuthAccessTokenSecret(LoginActivity.getAccessTokenSecret(context)); Configuration configuration = configurationBuilder.build(); final Twitter twitter = new TwitterFactory(configuration).getInstance(); new Thread(new Runnable() { private double x; @Override public void run() { boolean success = true; try { x = Math.random(); twitter.updateStatus(message +" "+x); } catch (TwitterException e) { e.printStackTrace(); success = false; } final boolean finalSuccess = success; callingActivity.runOnUiThread(new Runnable() { @Override public void run() { postResponse.onFinsihed(finalSuccess); } }); } }).start(); 

Consulte este tutorial para obtener más detalles.

Compruebe SocialAuth para Android . La nueva versión te ayuda a subir imágenes en twitter, así como obtener feeds y obtener álbumes.

Utilicé esto para compartir la foto en Twitpic.

 private void hello() { // TODO Auto-generated method stub String url; long result = 0; String oth = prefs.getString(OAuth.OAUTH_TOKEN, ""); String src = prefs.getString(OAuth.OAUTH_TOKEN_SECRET, ""); Configuration conf = new ConfigurationBuilder() .setOAuthConsumerKey(Constants.CONSUMER_KEY) .setOAuthConsumerSecret(Constants.CONSUMER_SECRET) .setOAuthAccessToken(oth).setOAuthAccessTokenSecret(src) .build(); OAuthAuthorization auth = new OAuthAuthorization(conf, conf.getOAuthConsumerKey(), conf.getOAuthConsumerSecret(), new AccessToken(conf.getOAuthAccessToken(), conf.getOAuthAccessTokenSecret())); ImageUpload upload = ImageUpload.getTwitpicUploader( Constants.twitpic_api_key, auth); Log.d(main_genral_class.TAG, "Start sending image..."); try { if (isFromCamera) { S_PHOTO_URL = S_PHOTO_URL.replace(" ", "%20"); url = upload.upload(" ", new URL(S_PHOTO_URL).openStream(), S_PHOTO_SMS); } else { Log.d("photo url twiter---->", S_PHOTO_URL); url = upload.upload(" ", new URL(S_PHOTO_URL).openStream(), S_PHOTO_SMS); } result = 1; Log.d(main_genral_class.TAG, "Image uploaded, Twitpic url is " + url); } catch (Exception e) { Log.e(main_genral_class.TAG, "Failed to send image"); e.printStackTrace(); } } 

En este código S_PHOTO_URL es la URL de la foto.

Como, S_PHOTO_URL = "http://www.thebiblescholar.com/android_awesome.jpg";

S_PHOTO_SMS = "hola, esto es de Android App!";

También puede personalizar el código y enviar el archivo en lugar de la URL.

Intente por favor esto le ayudará seguro.
