Android connection to mysql Database with php server

Question

I am about to make an app that connect to database and update listview every X seconds (connection via WiFi).

My questions:

1. Is it a good solution to keep connected app to wifi and update the list eg. every 10 seconds?
2. What is the easiest way to communicate with database via php scripts? I was looking for this and found example with HttpClient but in Android Studio it says that this is deprecated. Then I found HttpURLConnection but I have got no clue how to use it.

Thanks in advance for your help.

Answer 2

1. I think that's not quite good way. That will consume much battery and server's traffic will increase. Try push or increase interval. 10 seconds is too short.

2. Try this . I use this when I need a connection between server.
