如何从PhP服务器Android应用程序获取JsonArray？

Hi I have php code to encode an array and I want my android app to receive the array and store to the local variable

php code on server side:

echo json_encode(array('result'=>$result));

how to make android to receive the array from server. I'm thinking of using Volley libray but dont know how to implement

should be something like:

ArrayList eventdetail = repond(url...)

I Believe you need time to research. Seems like you have just started.

Their are lot of ways to do this.

You can use Rest API's or SOAP API's whichever you feel like. or You can build your own http client on android to request and recieve data from web server.

all the best.

For SOAP you can use Ksoap2

For implementing Volley this is the best source.

use below code to parse json array

               JSONParser jParser = new JSONParser();

                JSONObject json = jParser.getJSONFromUrl(url);

                JSONArray jArrayVersion = json.getJSONArray("result");

                for (int j = 0; j < jArrayVersion.length(); j++) {

                    JSONObject items = jArrayVersion.getJSONObject(j);

                    String namesv = items.getString("name");
                    String message = items.getString("message");

                   }
