I don't know how to import JSON Data to Arraylist. How can I import JSON Array in createMockList() ? Someone help me! I'm beginner. Sorry for my poor english. Thanks You!
I want to know how to replace with JSON Array?

Display to another activity json array result from onPostExecute

How do I get the json result from onPostExecute to another activity? I was able to get the user details from the database based on the username logged in.

It is because new activity starts before async task is completed. Just call function for start new activity in onPostExecute() function.
Pass values after fetching the details. Is the settext working properly? then you can give the intent at that scope, in the onPostexecute method. Look before doing this.Look this

onPostExecute gets called too late

First I will describe the process/problem briefly in words. Afterwards, I'll attach all of the code.
I start the android application in debug mode.
Main activity gets called.
It calls Activity2 via "intent".
Then (in onCreate) I start an Async activity in order to get information from a webserver. I do that with this command "new Kontakt(info1, info2, information).execute();"
I've put a break point at the onPostExecute method in "Kontakt" to see what happens. But!! It doesn't stop there. So then I figured, "okey, the doInBackground method didn't get called for some reason"
When I continue to run the code, as a surprise, onPostExecute gets called (somewhere at the end of onClick) and stops at the break point just the way I want it but than it's too late, because I'd like to have the output already in the onCreate method where I called "new Kontakt(info1, info2, information).execute();".
So why does it call onPostExecute too late and what can I do to make the process call it properly already in onCreate at the line "new Kontakt(info1, info2, information).execute();" in Activity2?
The code is below

In Activity2, when onCreate() calls new Kontakt(info1, info2, information).execute();:
an asynchronous task (Kontakt) is started in the background
the execution of onCreate() continues
so it's normal that you don't have the response immediately.
