ClasscastException android.support.v7.widget.ShareActionProvider to action.view.ActionProvider

Question

Below is my Activity Code.

The problem is that i am not able to use AppCompat library properly and its giving me

ClasscastException android.support.v7.widget.ShareActionProvider to action.View.ActionProvider

   import android.content.Intent;
   import android.os.Bundle;
   import android.support.v4.view.MenuItemCompat;
   import android.support.v7.app.ActionBarActivity;
   import android.support.v7.widget.ShareActionProvider;
   import android.view.Menu;
   import android.view.MenuItem;

    public class MainActivity extends ActionBarActivity{
android.support.v7.widget.ShareActionProvider shareAction;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    MenuItem item =(MenuItem) menu.findItem(R.id.menu_settings);
    shareAction = (ShareActionProvider) MenuItemCompat
            .getActionProvider(item);
    shareAction.setShareIntent(createShareIntent());
    return true;
}

public Intent createShareIntent() {
    Intent share = new Intent(Intent.ACTION_SEND);
    share.setAction(Intent.ACTION_SEND).putExtra(Intent.EXTRA_TEXT, "TEST")
            .setType("text/plain");
    return share;
}

}

According the Guide at developer.android.com i am using the library correctly

Below is my menu file

<menu xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:easyshare="http://schemas.android.com/apk/res-auto">

<item
    android:id="@+id/menu_settings"
    android:orderInCategory="100"
    easyshare:showAsAction="ifRoom"
    easyshare:actionProviderClass="android.support.v7.widget.ShareActionProvider"
    />
  </menu>

** Edited LogCat output ** Sorry earlier i was getting the exception as given in label but seeing now i am getting this error and somehow not able to find the problem

@CommonsWare: `android.widget.ShareActionProvider` isn't used, is it? I can only see `android.support.v7.widget.ShareActionProvider` here - so it's probably not a duplicate. — Trinimon, Oct 01 '13 at 20:09
"android.widget.ShareActionProvider isn't used, is it?" -- since the OP claims that it is the error, it must be used. Unfortunately, the OP did not post a complete stack trace. — CommonsWare, Oct 01 '13 at 20:14
@CommonsWare: I agree, it's a good guess - for sure. However, I can't see any evidence. Don't mind ... :) — Trinimon, Oct 01 '13 at 20:23
@CommonsWare Could u help me regarding this. because i am getting nowhere with the problem — Anuranjit Maindola, Oct 02 '13 at 06:09
hey, try here http://developer.android.com/reference/android/support/v7/widget/ShareActionProvider.html This is the standard sample from google in case of v7 actioncompat. — TeeTracker, Dec 09 '13 at 20:59

you need to replace the cast of ShareActionProvider like this

@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
MenuItem item =(MenuItem) menu.findItem(R.id.menu_settings);
shareAction = (android.support.v7.widget.ShareActionProvider) item.getActionProvider();
shareAction.setShareIntent(createShareIntent());
return true;
}

It should be work correctly. Please Test it and tell me if it work correctly.

No it didnt. Same error – Anuranjit Maindola Oct 01 '13 at 20:57
i have edited my code you can see the difference and try it. – wSakly Oct 01 '13 at 21:11
@Saklos- It wont work. There is a cast exception from ActionProvider to ShareActionProvider .Moreover the `item.getActionProvider` works in API 14 and above.API 14 and above is not the problem the problem is to to support Android 2.1 and above – Anuranjit Maindola Oct 01 '13 at 21:18
thank you for th einformation so in this case you cant use SharlockAction bar it will be help u http://actionbarsherlock.com/ – wSakly Oct 01 '13 at 21:35
Actually I cant use because this code is part of something big so i cannot use ActionbarSherlock (something big doesnot uses Sherlock) – Anuranjit Maindola Oct 01 '13 at 21:46
this is false men, it's depend from your competance of architechture – wSakly Oct 01 '13 at 22:04
