I am playing around the fragments tutorial found here on section 21. It works

  • 0

I am playing around the fragments tutorial found here on section 21. It works fine when my build target is android 4.0 but when i try to change it to make it work with android 2.2, i get Error inflating class fragment on the line setContentView(R.layout.main); on MainActivity class.

I already added the support package, changed classes ListFragment and DetailFragment to extend android.support.v4.app.ListFragment and android.support.v4.app.Fragment respectively. There are no compile errors.

Did I miss something? TIA!

–EDIT—
Made it work. I changed DetailActivity.java and MainActivity.java to extend FragmentActivity instead of just Activity. Everything’s okay now. But still don’t know why I have to do that.
