android.support.v4.app.FragmentTransaction required

entering in code like this:

FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();

comes up with this error "android.support.v4.app.FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();" and has this as a quick fix which does in fact remove the error:

android.support.v4.app.FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();

and i am typing this in my main activity which extends FragmentActivity . Does anybody know why? i have included:

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;

EDIT

 DescriptionFragment fragment = new DescriptionFragment();
            android.support.v4.app.FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
            ft.replace(R.id.pager, fragment);
            ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
            ft.commit();

changing getSupportFragmentManager() to getFragmentManager() requires me to change DescriptionFragment to android.app.Fragment...any ideas?

try this

public class DescriptionFragment extends android.support.v4.app.Fragment

instead of simply Fragment.

Ok...Just make a method for fragment and call this Like:

void addfragment(Fragment fragment, boolean addBacktoStack, int transition) {
    FragmentTransaction ft = getFragmentManager().beginTransaction();
    ft.replace(R.id.simple_fragment, fragment);
    ft.setTransition(transition);
    if (addBacktoStack)
        ft.addToBackStack(null);
    ft.commit();

}

Now Just call Your Fragment:

addfragment(new DescriptionFragment(this),true, FragmentTransaction.TRANSIT_FRAGMENT_OPEN);

Have you import android.support.v4.jar file to your project??

With getSupportFragmentManager() you are getting the supportLibrary fragmentManager instead of the systems fragmentManager. So you are working with a transaction of the supportlibrary.

This is the reason why you need to add all these imports and use android.support.v4.app.

If you want to get the systems fragmentManager just try to use getFragmentManager() instead getSupportFragmentManager().

Hope this helps
