Saya bermigrasi dari menggunakan Volley ke Retrofit, saya sudah memiliki kelas gson yang saya gunakan sebelumnya untuk mengubah respons JSONObject ke objek yang menerapkan penjelasan gson. Saat saya mencoba membuat http dapatkan permintaan menggunakan retrofit tapi kemudian aplikasi saya mogok dengan kesalahan ini:
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.getResponseSaya mengikuti panduan di situs retrofit dan saya membuat implementasi ini:
Ini adalah aktivitas saya di mana saya mencoba mengeksekusi permintaan retro http:
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();
}
}
}Antarmuka saya yang berubah menjadi API saya
public interface GitHubService {
@GET("/ **sample here** /{petId}/{otherPet}")
Call<Pet> getResponse(@Path("petId") String userId, @Path("otherPet") String otherPet);
}Dan akhirnya kelas Pet yang seharusnya menjadi respons:
public class Pet implements Parcelable {
public static final String ACTIVE = "1";
public static final String NOT_ACTIVE = "0";
@SerializedName("is_active")
@Expose
private String isActive;
@SerializedName("pet_id")
