Java – ActionBarSherlock type mAdded cannot be resolved or is not a field Watson.java

I spent a day looking for a solution to this error
I downloaded ActionBarSherlock and imported the library into Eclipse
I have fixed all the bugs and this is the last one
I checked all layouts with no xml errors, cleaned up the workspace and restarted Eclipse

Here is the error description:

Description Resource Path Location Type mAdded cannot be resolved or
is not a
field Watson.java /abs_library/src/android/support/v4/app line 59 Java
Problem

Code

if (mFragments.mAdded != null) {
                for (int i = 0; i < mFragments.mAdded.size(); i++) {
                    Fragment f = mFragments.mAdded.get(i);
                    if (f != null && !f.mHidden && f.mHasMenu && f.mMenuVisible
                            && f instanceof OnCreateOptionsMenuListener) {
                        show = true;
                        ((OnCreateOptionsMenuListener) f).onCreateOptionsMenu(
                                menu, inflater);
                        if (newMenus == null) {
                            newMenus = new ArrayList<Fragment>();
                        }
                        newMenus.add(f);
                    }
                }
            }

Thanks

If you update your android-support-v4 .jar, just replace those three lines of code

if (mFragments.mAdded != null) {
   for (int i = 0; i < mFragments.mAdded.size(); i++) {
      Fragment f = mFragments.mAdded.get(i);

with

List<Fragment> actives =  mFragments.getActiveFragments(null);
if (actives != null) {
   for (int i = 0; i < actives.size(); i++) {
       Fragment f = actives.get(i);

…

Everything will be fine
