Answer 1

Check your imports at the beginning of your classes. I guess there will be a import android.app.Fragment;. Change it to import android.support.v4.app.Fragment;. Maybe the error is caused by the menuX_Fragments which extend android.app.Fragment instead of the support fragment.

You can use import android.support.v4.app.Fragment for developing apps for lower android versions, fragments are introduced in Android 3.0.

Decide for one version of fragments and use it everywhere. I guess you mixed it up.
