2 ,OkHttp

----------------
okHttpGET();
okHttpGETAsyc();
okHttpPost();
okHttpPostFile();
----------------
private String okHttpGET() {
OkHttpClient client = new OkHttpClient();

Request request = new Request.Builder()
.url(ApiConstans.API_URL)
.build();
try {
Response response = client.newCall(request).execute();
Reader reder = response.body().charStream();
return response.body().string();
} catch (Exception ex) {

3,Retrofit

Retrofit retrofit = new Retrofit.Builder()
.baseUrl(ApiConstans.HOST)
.addConverterFactory(GsonConverterFactory.create())
.build();

RetrofitService service = retrofit.create(RetrofitService.class);
Call<RetrofitMode> data = service.getModeData("p");//p in the path means php
data.enqueue(new Callback<RetrofitMode>() {
@Override
public void onResponse(Response<RetrofitMode> response) {
textView.setText(response.toString() + "\r\n" + response.body().toString());
}

@Override
public void onFailure(Throwable t) {
textView.setText(t.getMessage().toString());
}
});

public interface RetrofitService {

@GET("/{p}/index.php")
Call<RetrofitMode> getModeData(@Path("p")String pOrjType);
}
