Question

For some reason the system does not find the attach and detach methods for Fragments like in here…

import android.app.Fragment;
import android.app.FragmentTransaction;

public void onTabUnselected(Tab tab, FragmentTransaction ft) {
        if (mFragment != null) {
        // Detach the fragment, because another one is being attached
        ft.detach(mFragment);
        }
    }

I get the above error in the compiler.
The project is based on Android 3.1 level 12. And I already resinstalled the complete Android 3.1 SDK.

I though all that would be part of Android 12?

All the other Fragment methods and references work fine.

Many thanks!

API Level 12 doesn’t have FragmentTransaction.detach(Fragment) API.
