HI Sono solo nuovo per il retrofit servizio e seguito questo tutorial https://www.simplifiedcoding.net/retrofit-android-tutorial-to-get-json-from-server/ funziona bene e ha voluto creare il mio molto proprio così ho usato un nuovo JSON web http://api.androidhive.info/contacts/ che contieneAndroid Retrofit alcuna risposta

I implementato la mia propria interfaccia ContactAPI.java
public interface ContactsAPI {
@GET("/contacts/")
public void getContacts(Callback<List<Contact>> response);}
e realizzato classe modello come questo Contact.java
public class Contact {
@SerializedName("id")
@Expose
private String id;
@SerializedName("name")
@Expose
private String name;
@SerializedName("email")
@Expose
private String email;
@SerializedName("address")
@Expose
private String address;
@SerializedName("gender")
@Expose
private String gender;
public String getId() {return id;}
public void setId(String id) {this.id = id;}
public String getName() {return name;}
public void setName(String name) {this.name = name;}
public String getEmail() {return email;}
public void setEmail(String email) {this.email = email;}
public String getAddress() {return address;}
public void setAddress(String address) {this.address = address;}
public String getGender() {return gender;}
public void setGender(String gender) {this.gender = gender;}}
poi finalmente implementato il mio Restadapter in MainActivity.class
public static final String ROOT_URL = "http://api.androidhive.info";
private ListView listView;
private List<Contact> contacts;
RestAdapter adapter = new RestAdapter.Builder().setEndpoint(ROOT_URL).build();
ContactsAPI api = adapter.create(ContactsAPI.class);
api.getContacts(new Callback<List<Contact>>() {
@Override
public void success(List<Contact> list, Response response) {
Toast.makeText(MainActivity.this,list.toString(),Toast.LENGTH_SHORT).show();
showList();
}
@Override
public void failure(RetrofitError error) {
//you can handle the errors here
Toast.makeText(MainActivity.this,"Error Occured:"+error.toString(),Toast.LENGTH_SHORT).show();
}
});
L'App funziona senza problemi, ma dopo 4 secondi di ritardo sarà promt un errore che è pubblico fallimento vuoto (errore RetrofitError) io non so cosa sto manca ho controllato il mio codice e non riesco a trovare nulla di sbagliato mi aiuti grazie in anticipo.
qual è il messaggio di errore? – Juvi
conoscere l'errore sarebbe sicuramente di aiuto. Hai il permesso di internet nel manifest? – Blackbelt
@Juvi - questo è l'errore che viene ai registri E/Surface: getSlotFromBufferLocked: buffer sconosciuto: 0xaa9ef1b0 – user3262438
