Twitter's access token isnt valid

I have a problem with my Android app when I try to login with Twitter. When I login and Twitter has given permission to my account to access, it shows the next message:
"Wait a moment!
The request form's token for this page isnt being valid. Is possible that it had was used or be expired because is a few old. Please, back to the site or aplicattion which sent to here an try again, probably it only was an error."
This is my code:
AlertManager:
package com.fsvp.manocio;
import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
public class AlertManager {
public void showAlertDialog(Context context, String title, String message, Boolean status) {
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle(title);
builder.setMessage(message);
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
}
});
AlertDialog alertDialog = builder.create();
alertDialog.show();
}
}
Connection Manager:
package com.fsvp.manocio;
import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
public class ConnectionManager {
private Context _context;
public ConnectionManager(Context context){
this._context = context;
}
public boolean isConnectingToInternet(){
ConnectivityManager connectivity = (ConnectivityManager) _context.getSystemService(Context.CONNECTIVITY_SERVICE);
if (connectivity != null)
{
NetworkInfo[] info = connectivity.getAllNetworkInfo();
if (info != null)
for (int i = 0; i < info.length; i++)
if (info[i].getState() == NetworkInfo.State.CONNECTED)
{
return true;

Tweet Multiple Pictures Android

Twitter recently released an update allowing users to attach up to four images to a tweet. I was wondering how to implement this in an Android application.
I've found a post that was made BEFORE Twitter released the update called "Posting multiple photos in a single tweet" (I'm not showing the link because I'm only allowed to show two links with less than 10 reputation).
Now, here is the Twitter API documentation describing how to attach multiple images to a tweet, the only problem is that I have no idea how to implement this in Android:
https://dev.twitter.com/docs/api/1.1/post/statuses/update_with_media
So I was thinking of two possible solutions - either modify one of these methods from the Twitter4j library( https://github.com/yusuke/twitter4j/tree/master/twitter4j-media-support/src/main/java/twitter4j/media) to allow for multiple image attachments OR directly implement the Twitter API documentation.
Any ideas how to do this?
Input is greatly appreciated!

I have shared the multiple images on Twitter in android using twitter4j library,it is working fine to share multiple and single image on twitter

for running above code please download the below library and put it in your app libs folder and add it as dependency in gradle file
(1)twitter4j-core-4.0.4.jar
(2)twitter4j-media-support-4.0.4.jar
(3)twitter4j-stream-4.0.4.jar
(4)signpost-commonshttp4-1.2.1.1.jar
(5)signpost-core-1.2.1.1.jar
(6)signpost-jetty6-1.2.1.1.jar
It is working fine, hope it will help for you also

can anyone tell me why i am getting null on Uri uri = getIntent().getData();...uri object value is null..thus this part is not executing
if(uri!=null && uri.toString().startsWith(CALLBACK)) {
String verifier = uri.getQueryParameter("oauth_verifier");

User user = twitter.showUser(token.getUserId());
String username = user.getName();
userName.setText("Logged as: " + username);
} catch (Exception e) {
Log.e("Login error: ", e.getMessage());
}
}

Check out this Demo links , you will get idea how it works and then try to implement own
you can download both
you have to just create your Twitter app.That is also explain by blogger.Follow them you will get two keys.
TWITTER_CONSUMER_KEY="**********************";
TWITTER_CONSUMER_SECRET="********************";
Replace inside your activity and run your project.

AsyncTask is not working properly in android 4.0

I have this async Task on android 2.3.5
class InternetConnexionErrorAsync extends AsyncTask<String, String, String>
{
#Override
protected void onPreExecute() {
super.onPreExecute();
mdpiImageView.setClickable(false);
journalsImageView.setClickable(false);
accountImageView.setClickable(false);
Toast.makeText(getBaseContext(),errorMessage , Toast.LENGTH_LONG).show();
}
#Override
protected String doInBackground(String... aurl) {
try {
Thread.sleep(3450);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(String unused)
{
finish();
}
}
Everything is working well.
When I try this in Android 4.0, I am newer accessint the onPostExecute.
Could you please help me. No error message, only that the onPostExecute is newer reached.

Whatever you need to update on the UI you need to do in onPostExecute.
The code below, take a look at onPostExecute - specifically the activity.xx() methods send updates to the main activity that do things on the UI.
For example:
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;
import library.DatabaseHandler;
import library.JSONParser;
import library.UserFunctions;
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
import org.json.JSONException;
import org.json.JSONObject;
import com.actionbarsherlock.R;
import android.app.ProgressDialog;
import android.content.Context;
import android.content.Intent;
import android.os.AsyncTask;
import android.support.v4.app.FragmentActivity;
import android.util.Log;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
public class LoginTask extends AsyncTask<String, Void, Integer> {
private ProgressDialog progressDialog;
private Polling activity;
private int id = -1;
private JSONParser jsonParser;
private static String loginURL = "http://davidjkelley.net/android_api/";
private static String registerURL = "http://davidjkelley.net/android_api/";
private static String KEY_SUCCESS = "success";
private static String KEY_ERROR = "error";
private static String KEY_ERROR_MSG = "error_msg";
private static String KEY_UID = "uid";
private static String KEY_NAME = "name";
private static String KEY_EMAIL = "email";
private static String KEY_CREATED_AT = "created_at";
private int responseCode = 0;
public LoginTask(Polling activity, ProgressDialog progressDialog)
{
this.activity = activity;
this.progressDialog = progressDialog;
}
#Override
protected void onPreExecute()
{
progressDialog.show();
}
protected Integer doInBackground(String... arg0) {
EditText userName = (EditText)activity.findViewById(R.id.emailEditText);
EditText passwordEdit = (EditText)activity.findViewById(R.id.passEditText);
String email = userName.getText().toString();
String password = passwordEdit.getText().toString();
UserFunctions userFunction = new UserFunctions();
JSONObject json = userFunction.loginUser(email, password);
// check for login response
try {
if (json.getString(KEY_SUCCESS) != null) {
String res = json.getString(KEY_SUCCESS);
if(Integer.parseInt(res) == 1){
//user successfully logged in
// Store user details in SQLite Database
DatabaseHandler db = new DatabaseHandler(activity.getApplicationContext());
JSONObject json_user = json.getJSONObject("user");
//Log.v("name", json_user.getString(KEY_NAME));
// Clear all previous data in database
userFunction.logoutUser(activity.getApplicationContext());
db.addUser(json_user.getString(KEY_NAME), json_user.getString(KEY_EMAIL),
json.getString(KEY_UID), json_user.getString(KEY_CREATED_AT));
responseCode = 1;
// Close Login Screen
//finish();
}else{
responseCode = 0;
// Error in login
}
}
} catch (NullPointerException e) {
e.printStackTrace();
}
catch (JSONException e) {
e.printStackTrace();
}
return responseCode;
}
#Override
protected void onPostExecute(Integer responseCode)
{
EditText userName = (EditText)activity.findViewById(R.id.emailEditText);
EditText passwordEdit = (EditText)activity.findViewById(R.id.passEditText);
if (responseCode == 1) {
progressDialog.dismiss();
activity.loginReport(responseCode);
userName.setText("");
passwordEdit.setText("");
//shared prefences, store name
}
if (responseCode == 0) {
progressDialog.dismiss();
activity.loginReport(responseCode);
}
//if(responseCode == 202)
//activity.login(id);
//else
//activity.showLoginError("");
}
}
Here's the main activity, you can see what loginReport does:
public class Polling extends SherlockFragmentActivity {
private ViewPager mViewPager;
private TabsAdapter mTabsAdapter;
private final static String TAG = "21st Polling:";
private Button loginButton;
private Button registerButton;
private CheckBox remember;
SharedPreferences sharedPreferences;
Toast toast;
ActionBar bar;
//DatabaseHandler ;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.v(TAG, "onCreate");
mViewPager = new ViewPager(this);
mViewPager.setId(R.id.pager);
setContentView(mViewPager);
bar = getSupportActionBar();
bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
bar.setDisplayShowTitleEnabled(false);
bar.setDisplayShowHomeEnabled(false);
mTabsAdapter = new TabsAdapter(this, mViewPager);
mTabsAdapter.addTab(bar.newTab().setText(R.string.login),
LoginFragment.class, null);
mTabsAdapter.addTab(bar.newTab().setText(R.string.economics),
EconFragment.class, null);
mTabsAdapter.addTab(bar.newTab().setText(R.string.elections),
ElectionsFragment.class, null);
mTabsAdapter.addTab(bar.newTab().setText(R.string.politics),
PoliticsFragment.class, null);
mTabsAdapter.addTab(bar.newTab().setText(R.string.science),
ScienceFragment.class, null);
mTabsAdapter.addTab(bar.newTab().setText(R.string.finance),
FinanceFragment.class, null);
mTabsAdapter.addTab(bar.newTab().setText(R.string.religion),
ReligionFragment.class, null);
mTabsAdapter.addTab(bar.newTab().setText(R.string.military),
MilitaryFragment.class, null);
mTabsAdapter.addTab(bar.newTab().setText(R.string.international),
InternationalFragment.class, null);
}
public void loginReport(int responseCode) {
DatabaseHandler db = new DatabaseHandler(getApplicationContext());
UserFunctions userFunctions = new UserFunctions();
Context context = getApplicationContext();
//login succeeded, sent when LoginTask doInBg sends a 1 to onPostExecute
if (responseCode == 1) {
loginButton = (Button)findViewById(R.id.loginButton);
loginButton.setText("Log Out");
int duration = Toast.LENGTH_LONG;
Toast toast = Toast.makeText(context, "Logged in.", duration);
toast.show();
bar.getTabAt(0).setText(db.getUserDetails().get(db.KEY_EMAIL));
//Log.v(TAG, db.getUserDetails().toString());
}
//login failed, sent when LoginTask doInBg sends a 0 to onPostExecute
if (responseCode == 0) {
int duration = Toast.LENGTH_LONG;
Toast toast = Toast.makeText(context, "Incorrect username/password", duration);
toast.show();
}
if (responseCode == 2) {
//logout button clicked, listened from within LoginFragment
//remove user from active sql db here rather than LoginFragment?!
bar.getTabAt(0).setText(R.string.login);
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, "Logged out", duration);
toast.show();
userFunctions.logoutUser(context);
}
}

The solution I adopted, after the suggestion of #Davek804 is that I replace the AsyncTask with a delayed runable like this:
private Runnable mMyRunnable = new Runnable()
{
public void run()
{
finish();
}
};
Toast.makeText(getBaseContext(),errorMessage , Toast.LENGTH_LONG).show();
Handler myHandler = new Handler();
myHandler.postDelayed(mMyRunnable, 3450);
So the effect will be the same.

I found the solution here
Instead of using :
task.execute();
use :
task.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, null);
