ShowLoginDialog cause crash

[klcmine]

I try to open loginDialog, but everytime it cause crash. We use Fragment "android.app" not "android.support.v4.app"

TurkcellIdManager turkcellIdManager = new TurkcellIdManager(ActivityMain.this, appId, false);
turkcellIdManager.showLoginDialog(this, true);

TurkcellIdManager line 174
tr.com.turkcell.turkcellid.TurkcellIdManager.a

Fatal Exception: java.lang.IllegalStateException: Fragment tr.com.a.a.h must be a public static class to be properly recreated from instance state.
