how to handle activity when returning null post launch of the camera application from the fragment

Question

In a fragment,I am having the view pager(using fragmentPageAdapter) and recycler views to display the images.I have option to take the pictures and add to both of them(viewpager and recycler),

During oncreateView of the fragment,adapter has been created with predefined set of images,when i try to access the photos from album location i am trying to use getActivity.getContentResolver() to get Photos,But getActivity() itself returns null post the launch of the photoapplication,i think the problem happens with detach & attach of the fragment,How to handle this scenarios?

OncreateView of fragment

    This Fragments extends basefragment which contains camera launch and Saves it in PhotoGallery

   LinearLayoutManager layoutManager
            = new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, false);

    mRecyclerView = (RecyclerView)v. findViewById(R.id.recycler_view);
    adapter  = new MyRecyclerAdapter(getActivity(),mJobSiteAlbum,getGalleryThumbnailViewCallBackListener);
    mRecyclerView.setLayoutManager(layoutManager);
    mRecyclerView.setAdapter(adapter);

Within Adapter

    public void onBindViewHolder(CustomViewHolder customViewHolder, int i) {
    MyObject photoObject = MyObjects.get(i);
    if(photoObject.getresId() == MyObject.LOCAL_IMAGE){

        Bitmap bitmap = mBaseFragment.getImageFromGallery(photoObject.getSelectedUri());//trying to retrive image from Gallery 
        if(bitmap!=null){
            Log.v("Bitmap>>>Wid",""+bitmap.getWidth());
            Log.v("Bitmap>>>Ht",""+bitmap.getHeight());
        }

        customViewHolder.imageView.setImageBitmap(bitmap);
        customViewHolder.imageView.getLayoutParams().height = 100;
        customViewHolder.imageView.getLayoutParams().width = 100;
        customViewHolder.imageView.requestLayout();



    }else   if(photoObject.getresId() == MyObject.WEB_IMAGE){
        customViewHolder.imageView.setImageUrl(photoObject.getthumbnailimageUrl(), loader);
    }
    customViewHolder.imageView.setOnClickListener(clickListener);
    customViewHolder.imageView.setTag(customViewHolder);

}
