Here I'm calling web services in nested Fragments which has TabLayout and ViewPager using AsyncTask. I've tried AsyncTasks by calling them all in onResume method of each Fragment as:
new FetchAllData(getActivity()).executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
and
new FetchAllData(getActivity()).execute();
Everything is fine but I get lots of issues:
App stops working without any dialog but it shows suspending all threads in logcat.
When we come on this fragment(which has nested tablayouts and viewpagers) from another activity which is showing in image, everything gets blank except Toolbar for 3 to 5 seconds. And all of sudden they come with complete data.
When we call this fragment from another fragment of same activity it freezes there and this fragments gets opened all of sudden there.
I hope you got my all issues if not please inform to me.

I know I'm late but as I saw your lots of questions regarding of processing of app I found no error in anything but still I wanna say please check if you're calling any TypeFace by creating a new object each time so comment them and run your code and let me know.
I've also faced this type of issue a long time ago just beacuse of TypeFace so please give a try to my answer and let me know.
Thanks.
