JsonRequester

An Android library for sending fast and clean JSON request, using Volley

##Getting started

Dependency

dependencies {
    compile 'com.android.volley:volley:1.0.0'
    compile 'com.alirezaafkar:json-requester:1.1.4'
}

Usage

Initialize Requester in your Application class in the onCreate() method.

@Override
public void onCreate() {
    super.onCreate();
    
    Map<String, String> header = new HashMap<>();
    header.put("charset", "utf-8");
    
    String baseUrl = "http://example.com/api/";
    
    new Requester.Config(getApplicationContext()).baseUrl(baseUrl).header(header); 
}

Create a requester

JsonObjectRequester mRequester;
mRequester = new RequestBuilder(this)
            .requestCode(REQUEST_CODE)
            .contentType(ContentType.TYPE_JSON) //or ContentType.TYPE_FORM
            .showError(true) //Show error with toast on Network or Server error
            .shouldCache(true)
            .priority(Request.Priority.NORMAL)
            .allowNullResponse(true)
            .tag(REQUEST_TAG)
            .addToHeader("token", user_token)
            .buildObjectRequester(listener); //or .buildArrayRequester(listener);

Create a listener

private class JsonObjectListener extends Response.SimpleObjectResponse {
        @Override
        public void onResponse(int requestCode, @Nullable JSONObject jsonObject) {
          //Ok
        }

        @Override
        public void onErrorResponse(int requestCode, VolleyError volleyError, @Nullable JSONObject errorObject) {
          //Error (Not server or network error)
        }

        @Override
        public void onFinishResponse(int requestCode, VolleyError volleyError, String message) {
          //Network or Server error
        }

        @Override
        public void onRequestStart(int requestCode) {
          //Show loading or disable button
        }

        @Override
        public void onRequestFinish(int requestCode) {
          //Hide loading or enable button
        }
}

Request

mRequester.request(Methods.GET, url);
mRequester.request(Methods.POST, url, body); // application/x-www-form-urlencoded
mRequester.request(Methods.POST, url, json); // application/json

Callbacks

Set callback to null on destroy

Activity

@Override
    protected void onDestroy() {
        super.onDestroy();
        if (isFinishing()) {
            mRequester.setCallback(null);
        }
    }

Fragment

@Override
    public void onDetach() {
        super.onDetach();
        if (isRemoving() || getActivity().isFinishing()) {
            mRequester.setCallback(null);
        }
    }

Nested Fragment

if (getParentFragment().isRemoving() ||
                isRemoving() || getActivity().isFinishing()) {
            mRequester.setCallback(null);
}

###Override strings
