Not able to call android annotation methods in fragment?

Question

I am using Android annotation in inflate the Fragment:

@EFragment(R.layout.fragment_sample)
public class SampleFragment extends Fragment {    
    public static SampleFragment newInstance(Context context) {
        mContext = context;
        SampleFragment samplefragment = new SampleFragment_();
        return samplefragment;
    }

    @Override
    public void onActivityCreated(@Nullable Bundle savedInstanceState){
        super.onActivityCreated(savedInstanceState);
    }

    @Override
    public void onCreate(Bundle bundle) {
        super.onCreate(bundle);
    }

    @AfterViews
   public void afterViewsCreated(){
        LinearLayoutManager linearLayoutManager = new LinearLayoutManager(mContext);
  }}

I am invoking the instance of above fragment class from an Activity:

 SampleFragment.newInstance(getApplicationContext());

After enabling debug point in the code. Code flow is only limited to newInstance method. Debugger is not even going to onActivityCreated() , onCreate() and afterViewsCreated(). @AfterViews needs to be get called.

Why is this so happening?

Are you actually adding the fragment to your activity using the `FragmentManager`? — tachyonflux, Oct 19 '16 at 22:18

All you appear to be doing is creating an instance of the fragment. You don't appear to be actually calling to the FragmentManager to add()/replace() this new instance.

Try:

Fragment fragment = SampleFragment.newInstance(getApplicationContext());

getFragmentManager.beginTransation()
    .add(<ID RES>, fragment, <FRAGMENT TAG>)
    .commit();

Where ID RES is your resource id and FRAGMENT TAG is your fragment tag, if required.

See this post for more info on using FragmentManager.
