FragmentPagerAdapter, Fragments, support.v4 and support.v13

Question

My Current Situation

I am working on an existing app that is using CustomFragment derived from android.app.Fragment. I want to add a new functionnality with a ViewPager which will show my CustomFragments. For that I need to use a FragmentPagerAdapter.

Oooh snap !

Here I am, importing android.support.v4.view.ViewPager and android.support.v4.app.FragmentPagerAdapter to achieve my goal. And now the funny part begins :

• When I try to use my FragmentPagerAdapter with my CustomFragment, I get the classic error Type mismatch: cannot convert from android.app.Fragment to android.support.v4.app.Fragment

• Knowing that I can't change the whole app fragments to android.support.v4.app.Fragment, I searched and found that the android.support.v13.app.FragmentPagerAdapter was made to use native fragments. Great !

• Not great. When I try to import the v13 FragmentPagerAdapter, I get the error The import android.support.v13 cannot be resolved. For the record, I checked in SDKManager what support version is installed : v19.0.1

• I searched again, because of course I can't be the first one with that problem. I found that you can't use support.v4 and support.v13 in the same app because v4 is included in v13. And for everyone that encoutered my problem, the solution was to use only android.support.v4.app.FragmentPagerAdapter and android.support.v4.app.Fragment

What to do now ?

Since I have to use android.app.Fragment and I can't use only support.v4, I don't know where to go search next. Any help would be highly appreciated !

Answer 1

Well that is simply not possible. I went to use support.v4.app.Fragment.
