obteniendo NetworkOnMainThreadException al integrar twitter API en android

android-asynctask android-twitter

Question

He buscado mucho pero no he podido encontrar una solución. Estoy tratando de integrar Twitter en mi aplicación de Android. Funciona bien en el emulador pero no funciona bien en Honeycomb y dispositivos superiores. A continuación, adjunté el error log cat con el código.

TwitterUtils.java

public static boolean isAuthenticated(SharedPreferences prefs) {

        String token = prefs.getString(OAuth.OAUTH_TOKEN, "");
        String secret = prefs.getString(OAuth.OAUTH_TOKEN_SECRET, "");

        AccessToken a = new AccessToken(token,secret);
        Twitter twitter = new TwitterFactory().getInstance();
        twitter.setOAuthConsumer(Constants.CONSUMER_KEY, Constants.CONSUMER_SECRET);
        twitter.setOAuthAccessToken(a);

        try {
            twitter.getAccountSettings();
            return true;
        } catch (TwitterException e) {
            return false;
        }
    }

    public static void sendTweet(SharedPreferences prefs,String msg) throws Exception {
        String token = prefs.getString(OAuth.OAUTH_TOKEN, "");
        String secret = prefs.getString(OAuth.OAUTH_TOKEN_SECRET, "");

        AccessToken a = new AccessToken(token,secret);
        Twitter twitter = new TwitterFactory().getInstance();
        twitter.setOAuthConsumer(Constants.CONSUMER_KEY, Constants.CONSUMER_SECRET);
        twitter.setOAuthAccessToken(a);
        twitter.updateStatus(msg);
    }

clase donde se implementa el botón:

case R.id.btweet:
            Toast.makeText(this, "Recipe Tweet will be posted on your profile", 5000).show();
            try{
            if (TwitterUtils.isAuthenticated(prefs)) {
                sendTweet();
            } else {
                Intent i = new Intent(getApplicationContext(), PrepareRequestTokenActivity.class);
                i.putExtra("tweet_msg",getTweetMsg());
                startActivity(i);
            }
            }catch(Exception e){
                e.printStackTrace();
            }
            break;

Answer 1

No puede usar acciones de red en el hilo principal, debe implementar un AsyncTask que AsyncTask las acciones de red en su método doInBackground .

Prueba esto en tu botón:

Toast.makeText(this, "Recipe Tweet will be posted on your profile", 5000).show();
            try{
            if (TwitterUtils.isAuthenticated(prefs)) {
                new AsyncTask<Void,Void,Void>(){

                    protected Void doInBackground(Void... args){
                        sendTweet();
                        return null;
                    }

                }.execute();
            } else {
                Intent i = new Intent(getApplicationContext(), PrepareRequestTokenActivity.class);
                i.putExtra("tweet_msg",getTweetMsg());
                startActivity(i);
            }
            }catch(Exception e){
                e.printStackTrace();
            }
            break;

Answer 2

Prueba esto:

Reemplace este código:

if (TwitterUtils.isAuthenticated(prefs)) {

Con lo siguiente:

    new AsyncTask<SharedPreferences,Object, Boolean>() {

        @Override
        protected Boolean doInBackground(SharedPreferences... params) {
            return TwitterUtils.isAuthenticated(params[0]);
        }

        @Override
        protected void onPostExecute(Boolean isAuthenticated) {
            if (isAuthenticated) {
                // Do processing after successful authentication
                    sendTweet();
            }
            else {
                // Do processing after authentication failure
                    Intent i = new Intent(getApplicationContext(), PrepareRequestTokenActivity.class);
                    i.putExtra("tweet_msg",getTweetMsg());
                    startActivity(i);
            }
        }
    }.execute(prefs);

escriba estas líneas y en oncreate y no le dará excepción

//-----------------Checking thread policy
    int SDK_INT = android.os.Build.VERSION.SDK_INT;
    if (SDK_INT >= 10) {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
                .permitAll().build();
        StrictMode.setThreadPolicy(policy);
    }
