HTTP 통신 라이브러리

retrofit

step 1.

manifest

<uses-permission android:name="android.permission.INTERNET"/>

step 2.

build.gradle (Module:app)

compile "com.squareup.retrofit2:retrofit:2.0.0"
compile "com.squareup.retrofit2:converter-gson:2.0.0"

step 3.

Make RestService class.

public interface RestService {

   String ENDPOINT = "Url path";


@GET("경로")
Call<Map<Object, Object>> 메소드명(@Path("lat") String lat, @Path("lon") String lon);

@POST("경로")
Call<Map<Object, Object>> login(@Body Map<Object, Object> body);


  class Creator{
       public static RestService newRestService(){

           Gson gson = new GsonBuilder()
                   .setDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'")
                   .create();
           Retrofit retrofit = new Retrofit.Builder()
                   .baseUrl(RestService.ENDPOINT_)
                   .addConverterFactory(GsonConverterFactory.create(gson))             
                   .client(SSLConnect.getInstance().createSSLClient())             
                                                  // ssl(https) 사용시 주석해제할것
                   .build();
           return retrofit.create(RestService.class);
      }
  }
}

step 4.

RestService를 사용해서 http 통신

RestService restService = new RestService.Creator().newRestService();
final Call<Map<Object,Object>> call = restService.getUserInfo(~~~);
call.enqueue(new Callback<Map<Object, Object>>() {
           @Override
           public void onResponse(Call<Map<Object, Object>> call, Response<Map<Object, Object>> response) {
               if (!response.isSuccessful()) {
                   Toast.makeText(activity, "Sorry, failed..", Toast.LENGTH_SHORT).show();
                   return;
               }

               Map<Object, Object> body = response.body();
               Map<Object, Object> one = (Map<Object, Object>) body.get("body");
               Map<Object, Object> data = (Map<Object, Object>) one.get("data");

               String name = (String)data.get("name");
               String email = (String)data.get("email");
               String profileUrl = (String)data.get("profileUrl");
           }
           @Override
           public void onFailure(Call<Map<Object, Object>> call, Throwable t) {
               Toast.makeText(activity, "Network Error : " + t.getMessage(),
           }
       });

Gilde

step 1.

manifest

<uses-permission android:name="android.permission.INTERNET"/>

step 2.

build.gradle(Module:app)

compile 'com.github.bumptech.glide:glide:3.6.0'
compile 'jp.wasabeef:glide-transformations:1.0.6@aar'  // 이미지 변형 ( 원형 )

step 3.

이미지뷰과 url로 이미지 삽입

Glide.with(context)
      .load({id})
      .bitmapTransform(new CropCircleTransformation(bitmapPool))
      .override(130,130)
      .into({view});

주의 : bitmapPool은 새로 생성해야 한다. (default로 생성 가능)

Callback

callback 사용 이유?
