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;
}

return false;

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

Use the new Twitter Fabric SDK for Android. Requires sign up first. If you don't want to wait to be approved for the sign up, then I recommend using the following link
https://github.com/Rockncoder/TwitterTutorial
The link above explains how to retrieve tweets. You should be able to use the above link COMBINED with the information in the link below to POST tweets!
https://dev.twitter.com/overview/documentation
First i have downloaded twitter4j-3.0.3 and put its .jar files into libs folder of my eclipse app.After that i create an app on https://dev.twitter.com/ and get all the credentials needed and gave callback url as https://google.co.in
Now my code is as follows

Now when i run my application i got this window
and apart from that when i am clicking on that button twitter log in ...that button is not working..need help
}
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");
try {

} 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.
First Example
Second Example
Enjoy.!!!
First, I have all configured (twitter keys, callback in the manifest, etc), then I do the call to twitter and get browser open, then I signIn in twitter and I accept the application, then the browser returns to application and try to get the response from twitter, but I get NULL as answer.

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.

Here's the main activity, you can see what loginReport does:

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),

}
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);
