NetworkConnection 
Overview
NetworkConnection is a simple library to http request support. this mean goal is to provide a very simple interface to developer.
Gradle
compile 'com.github.rudda:networkconnetion:0.0.1'
Permissions
add line in android manifest file
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
Simple GET Request -with Return JSONArray
1º step:
you must implements JsonArrayListener interfacepublic class MainActivity extends AppCompatActivity implements JsonArrayListener
2º step:
you must to instance customRequest class and set attribuites base url ( **setBaseUrl** ) , router ( **setRouter** ) and the method to request ( **GET or POST** ) this example GET. CustomRequest customRequest = new CustomRequest();
customRequest.setBaseUrl("http://localhost/users"); //base url
customRequest.setRouter("/"); //router to REST API
customRequest.setMethod(Request.Method.GET);// methods ( get or post )
customRequest.setResult(0); //optional
NetworkConnection.getInstance(this).execute(this, customRequest);
3º step:
the return.the return can come in three states: success, fail and loading. The first state is always loading the second state can be success or fail. warning: you can also use the requestCode to represent a specific call.
@Override
public void sucess(JSONArray Jsonarray, int requestCode) {
Toast.makeText(this, "sucess", Toast.LENGTH_SHORT).show();
TextView tv = (TextView) findViewById(R.id.response);
tv.setText(Jsonarray.toString());
}
@Override
public void fail(String message, int requestCode) {
Toast.makeText(this, "falha", Toast.LENGTH_SHORT).show();
}
@Override
public void loading(boolean loading, int requestCode) {
Toast.makeText(this, "carregando...", Toast.LENGTH_SHORT).show();
}
add headers
you must instantiate a hashmap of type <string, string> add key and respective values. Then just add the hashmap to the setHeader method of an instance of the CustomRequest class. the example below shows how to add an authorization header.
HashMap<String, String> params = new HashMap<>();
params.put("Authorization", "Basic " + CustomRequest.generateAutorizationHeader(email, pass));
customRequest.setHeaders(params);
working with JsonObject or String
how to work JsonObject or String? Easy :) ... do you must to implement JSONObjectListener and/or StringListener interface as shown below.
public class MainActivity extends AppCompatActivity implements StringListener{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
CustomRequest customRequest = new CustomRequest();
customRequest.setBaseUrl("http://localhost/users"); //base url
customRequest.setRouter("/"); //router to REST API
customRequest.setMethod(Request.Method.GET);// methods ( get or post )
customRequest.setResult(0); //optional
NetworkConnection.getInstance(this).execute(this, customRequest);
}
public void fail(String message, int requestCode) {
}
@Override
public void loading(boolean loading, int requestCode) {
}
@Override
public void sucess(String string, int requestCode) {
}
}
OR
public class MainActivity extends AppCompatActivity implements JSONObjectListener{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
CustomRequest customRequest = new CustomRequest();
customRequest.setBaseUrl("http://localhost/users"); //base url
customRequest.setRouter("/"); //router to REST API
customRequest.setMethod(Request.Method.GET);// methods ( get or post )
customRequest.setResult(0); //optional
NetworkConnection.getInstance(this).execute(this, customRequest);
}
public void fail(String message, int requestCode) {
}
@Override
public void loading(boolean loading, int requestCode) {
}
@Override
public void sucess(JSONObject jsonObject, int requestCode) {
}
}
Simple Post Request
CustomRequest customRequest = new CustomRequest();
customRequest.setBaseUrl("http://localhost/users"); //base url
customRequest.setRouter("/"); //router to REST API
customRequest.setMethod(Request.Method.POST);// methods ( get or post )
customRequest.setResult(0); //optional
NetworkConnection.getInstance(this).execute(this, customRequest);
add params to Post Request
CustomRequest customRequest = new CustomRequest();
customRequest.setBaseUrl("http://localhost/users"); //base url
customRequest.setRouter("/"); //router to REST API
customRequest.setMethod(Request.Method.POST);// methods ( get or post )
customRequest.setResult(0); //optional
HashMap<String, String> params= new HashMap<>();
params.put("param_1", "value_1");
params.put("param_2", "value_2");
params.put("param_3", "value_3");
customRequest.setParams(params); //only POST
NetworkConnection.getInstance(this).execute(this, customRequest);
