Common Fragment for all Fragments (using DataBinding)

BaseFragment.java

public abstract class BaseFragment extends Fragment {

    /**
     * DataBinding Object
     */
    private ViewDataBinding mBindingObject;

    /**
     * Context common
     */
    public Context mContext;

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);
        mContext = context;
    }

    public BaseFragment() {
        // Required empty public constructor
    }

    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        mBindingObject = DataBindingUtil.inflate(inflater, getLayoutResId(), container, false);

        init();

        return mBindingObject.getRoot();
    }

    /**
     * Get Layout Resource ID
     * @return Layout Id
     */
    public abstract int getLayoutResId();

    /**
     * Initialization for members
     */
    public abstract void init();

    /**
     * Getting Binding Object
     * @return Binding Object
     */
    public ViewDataBinding getBindingObj() {
        return mBindingObject;
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        try {
            Runtime.getRuntime().gc();
            System.gc();
        } catch (Exception ignored) {
        }
    }
}

MainFragment.java

public class MainFragment extends BaseFragment {

    FragmentMainBinding mBinding;

    @Override
    public int getLayoutResId() {
        return R.layout.fragment_main;
    }

    @Override
    public void init() {
        mBinding = (FragmentMainBinding) getBindingObj();
    }
}
