Question

我尝试使用改造来创建一个连接到服务器的服务。但每当我尝试连接时，它都无法达到回调成功或失败的方法。它确实得到了结果，但在达到成功或失败方法之前就停止了，所以它使我的应用程序没有响应。我以前成功地使用过改造，但我没有使用服务，现在我需要在服务中做到这一点并且它不会工作。请帮我。提前谢谢。

这是我的服务类：

public class ConnectionService extends Service implements Messaging,UserManagement, Callback<Response>{

public final IBinder myBinder = new MyBinder();
public final RestAdapter restAdapter = new RestAdapter.Builder()
        .setEndpoint(Api.API_URL)
        .setClient(new OkClient(new OkHttpClient()))
        .setLogLevel(RestAdapter.LogLevel.FULL)
        .build();
private String jsonResponse = "";
private final Object object = new Object();
private Gson gson = new Gson();

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    return super.onStartCommand(intent, flags, startId);
}

@Override
public IBinder onBind(Intent intent) {
    return myBinder;
}

@Override
public boolean getInbox(String token, long limit, long page) {
    return false;
}

@Override
public boolean getMessage(String token, int id_member, long limit, long page) {
    return false;
}

@Override
public boolean sendMessage(String token, int id_teman, String message) {
    return false;
}

@Override
public boolean hideMessage(String token, long id_message) {
    return false;
}

@Override
public boolean getToyotaMessage(String token, long limit, long page) {
    return false;
}

@Override
public void showNotification(String message) {

}

@Override
public boolean Signup(String fullname, String email, String password) {

    return false;
}

@Override
public Me Login(String email, String password) {
    Me me = new Me(email,password);
    Api.Login login = restAdapter.create(Api.Login.class);
    login.fetch(me,this);
    try{
        synchronized (object){
            object.wait();
            if(jsonResponse != null && !jsonResponse.equals("")){
                Type tipe = new TypeToken<ApiResponse<Me>>(){}.getType();
                ApiResponse<Me> apiResponse = gson.fromJson(jsonResponse,tipe);
                Metadata metadata = apiResponse.metadata;
                if(metadata.code==200){
                    return apiResponse.data.get(0);
                }
            }
        }
    }catch (Exception e){
        e.printStackTrace();
    }
    return null;
}

@Override
public void success(Response response, Response response2) {
    synchronized (object){
        jsonResponse = Utils.convertResultToString(response);
        Log.d(ConnectionService.class.getSimpleName(),"Success. Response: "+jsonResponse);
        object.notifyAll();
    }
}

@Override
public void failure(RetrofitError retrofitError) {
    synchronized (object){
        jsonResponse = null;
        object.notifyAll();
    }
}

public class MyBinder extends Binder{
    public ConnectionService getInstance(){
        return ConnectionService.this;
    }
}
}

连接发生在函数Login中。

这是我的Api登录界面：

public class Api {

public interface Signup{

    @POST(Methods.SIGNUP)
    void fetch(
            @Body Me me,
            Callback<Response> callback
    );
}
public interface Login{
    @POST(Methods.LOGIN)
    void fetch(
            @Body Me me,
            Callback<Response> callback
    );
}
}

我的mainActivity里面调用了我的服务中的Login方法：

public class MainActivity extends ActionBarActivity {

public boolean isLoggedin = false;
public Me me = null;

public ConnectionService myService;
public ServiceConnection serviceConnection = new ServiceConnection() {
    @Override
    public void onServiceConnected(ComponentName componentName, IBinder iBinder) {
        Log.d(MainActivity.class.getSimpleName(),"On Service Connected");
        myService = ((ConnectionService.MyBinder)iBinder).getInstance();
        login();
    }

    @Override
    public void onServiceDisconnected(ComponentName componentName) {
        Log.d(MainActivity.class.getSimpleName(),"On Service Connected");
        myService = null;
    }
};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

private void login(){
    if(myService != null) {
        me = myService.Login(Settings.EMAIL, Settings.cred);
        if (me != null) {
            Log.d(MainActivity.class.getSimpleName(), "full name: " + me.fullname);
            isLoggedin = true;
        }
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

@Override
protected void onStart() {
    super.onStart();
    if(myService == null){
        bindService(new Intent(this,ConnectionService.class),serviceConnection, Context.BIND_AUTO_CREATE);
        //startActivity(new Intent(this,ConnectionService.class));
    }
}

@Override
protected void onDestroy() {
    super.onDestroy();
    if(myService != null){
        unbindService(serviceConnection);
        //stopService(new Intent(this,ConnectionService.class));
    }
}
}

我在服务连接后获得的响应：

如上面的响应中所示，它在连接获得结果后结束，并且从不调用成功或失败方法。

Answer 1

嗯，你不应该告诉主线程等待。这是不好的做法，也是你看到ANR的原因。而是在一个线程中进行，尽管异步调用的重点是你不需要等待。

如果您真的想进行阻止调用，为什么不重命名接口方法以返回对象而不是void。然后你可以按照同步方法，你不需要你的服务扩展回调（我不是btw的忠实粉丝）。

Answer 2

就我而言，问题是Android Studio Emulator。在真正的android设备onFailure或onResponse中始终被称为。还向OkHttp添加超时：

    val httpClient = OkHttpClient.Builder()
        .readTimeout(60, TimeUnit.SECONDS)
        .connectTimeout(60, TimeUnit.SECONDS)
        .writeTimeout(60, TimeUnit.SECONDS)
        .build()

改造有效，但回调并没有调用成功或失败方法 - Android
