Volley kullanmaktan Retrofit'e geçerken, JSONObject yanıtını gson açıklamalarını uygulayan bir nesneye dönüştürmek için daha önce kullandığım gson sınıfına zaten sahibim. Güçlendirme kullanarak http isteği almaya çalıştığımda, ancak daha sonra uygulamam şu hatayla çöküyor:
Unable to start activity ComponentInfo{com.lightbulb.pawesome/com.example.sample.retrofit.SampleActivity}: java.lang.IllegalArgumentException: Unable to create converter for class com.lightbulb.pawesome.model.Pet
for method GitHubService.getResponse
Güçlendirme sitesindeki kılavuzu takip ediyorum ve şu uygulamaları buluyorum:
Bu, retro http talebini yerine getirmeye çalıştığım faaliyetim:
public class SampleActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sample);
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("**sample base url here**")
.build();
GitHubService service = retrofit.create(GitHubService.class);
Call<Pet> callPet = service.getResponse("41", "40");
callPet.enqueue(new Callback<Pet>() {
@Override
public void onResponse(Response<Pet> response) {
Log.i("Response", response.toString());
}
@Override
public void onFailure(Throwable t) {
Log.i("Failure", t.toString());
}
});
try{
callPet.execute();
} catch (IOException e){
e.printStackTrace();
}
}
}
API'm oldu arayüzüm
public interface GitHubService {
@GET("/ **sample here** /{petId}/{otherPet}")
Call<Pet> getResponse(@Path("petId") String userId, @Path("otherPet") String otherPet);
}
Ve son olarak cevabı olması gereken Pet sınıfı:
