I'm using actionbar tabs because I need the navigation elements to be on every page. I'm using ActionBarSherlock for backwards compatibility (minimum API 8, target API 17). My MainActivity extends SherlockFragmentActivity. In my onCreate() for that, I have

ActionBar actionBar = getSupportActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

actionBar.setDisplayShowTitleEnabled(true);

Tab tab1 = actionBar.newTab().setText("My Pages")
    .setTabListener(new MyPagesFragment());

Tab tab2 = actionBar.newTab().setText("Search")
    .setTabListener(new SearchFragment());

Tab tab3 = actionBar.newTab().setText("About")
    .setTabListener(new AboutFragment());

// Start with the second tab selected.
actionBar.addTab(tab1, 0, false);
actionBar.addTab(tab2, 1, true);
actionBar.addTab(tab3, 2, false);

All the tab fragments are SherlockListFragments that implement ActionBar.TabListener, and do this

@Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
    ft.replace(android.R.id.content, this, "mypages");
}

@Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
    ft.remove(this);
}

@Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
    // Force a complete reload.
    onTabSelected(tab, ft);
}

The search page has an EditText and uses its value in an AsyncTask to fetch data from an API and add it to an SQLite database, before calling

((MainActivity) getActivity()).showDetailView(responseCode);

to show the details, which is a method in my MainActivity as follows:

protected void showDetailView(long codeID) {
    SherlockFragment detailFragment = new DetailFragment();
    Bundle args = new Bundle();
    args.putLong("codeID", codeID);
    detailFragment.setArguments(args);

    FragmentManager manager =
android android-fragments
