Android Volley JsonArrayRequest to Post ArrayList data to the server
Hi Everyone in this article, I am sharing how to post an ArrayList data to a server using volley. Android Volley JsonArrayRquest Post data to the server. First of getting an array list of data to JSONArray and using the volley network library to post the list data to the server on a button click post the Android Volley JsonArrayRequest to Post ArrayList data to the server.
So Let Start on this Topic send Android Volley JsonArrayRequest to Post ArrayList data to the server, and store data in the local recycler view list. Create a user form and use username and email and store form data to an ArrayList and send it to the server.
Store Data in Locle recyclerView list and send to the server
