我正在使用Retrofit 2 + RxAndroid，这个代码在Marshmallow和Lollipop设备上运行很好，但是没有使用kitkat设备。
@OnClick(R.id.login_btn)
public void onLoginClicked() {
loginBtn.setEnabled(false);
AuthenticationAPI authApi = ServiceCreator.createService(AuthenticationAPI.class, null);
authApi.login(new LoginUserRequest(emailEditText.getText().toString(), passwordEditText.getText().toString()))
.observeOn(AndroidSchedulers.mainThread())
.subscribe(verifyEmailResponse -> Log.i("TEST", "onNext: " + verifyEmailResponse.success),
throwable -> {
handleError(throwable);
loginBtn.setEnabled(true);
});
}
ServiceCreator.java
public class ServiceCreator {
private static OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
private static final int DEFAULT_TIMEOUT = 30; //seconds
private static Gson gson = new GsonBuilder().setDateFormat("yyyy-MM-dd'T'HH:mm:ss").create();
private static RxJavaCallAdapterFactory rxAdapter = RxJavaCallAdapterFactory.createWithScheduler(Schedulers.io());
private static Retrofit.Builder builder = new Retrofit.Builder()
.baseUrl(BuildConfig.REST_BASE_ENDPOINT)
.addConverterFactory(GsonConverterFactory.create(gson))
.addCallAdapterFactory(rxAdapter);
public static <RESTService> RESTService createService(Class<RESTService> service, String userToken) {
if (BuildConfig.REST_DEBUG) {
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.BODY);
httpClient.addInterceptor(logging);
}
if (StringUtils.isNotBlank(userToken)) {
httpClient.addInterceptor(chain -> {
Request original = chain.request();
Request request = original.newBuilder()
.header(Constants.AUTHORIZATION_HEADER, userToken)
.method(original.method(), original.body())
.build();
return chain.proceed(request);
});
}
httpClient.connectTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS);
httpClient.readTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS);
httpClient.writeTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS);
Retrofit retrofit = builder.client(httpClient.build()).build();
return retrofit.create(service);
}
public static Retrofit retrofit() {
return builder.client(httpClient.build()).build();
}
}

谢谢！

发生错误是因为我一遍又一遍地添加相同的拦截器，新版本可能是。
public class ServiceCreator {
private OkHttpClient.Builder httpClient;
private static final int DEFAULT_TIMEOUT = 30; //seconds
private Gson gson;
private RxJavaCallAdapterFactory rxAdapter;
private Retrofit.Builder builder;
private static ServiceCreator mInstance = null;
private ServiceCreator() {
httpClient = new OkHttpClient.Builder();
gson = new GsonBuilder().setDateFormat("yyyy-MM-dd'T'HH:mm:ss").create();
rxAdapter = RxJavaCallAdapterFactory.createWithScheduler(Schedulers.io());
builder = new Retrofit.Builder()
.baseUrl(BuildConfig.REST_BASE_ENDPOINT)
.addConverterFactory(GsonConverterFactory.create(gson))
.addCallAdapterFactory(rxAdapter);
if (BuildConfig.REST_DEBUG) {
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.BODY);
httpClient.addInterceptor(logging);
}
}
public static ServiceCreator getInstance() {
if (mInstance == null) {
mInstance = new ServiceCreator();
}
return mInstance;
}
public <RESTService> RESTService createService(Class<RESTService> service, String userToken) {
if (StringUtils.isNotBlank(userToken)) {
httpClient.addInterceptor(chain -> {
Request original = chain.request();
Request request = original.newBuilder()
.header(Constants.AUTHORIZATION_HEADER, userToken)
.method(original.method(), original.body())
.build();
return chain.proceed(request);
});
}
httpClient.connectTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS);
httpClient.readTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS);
httpClient.writeTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS);
Retrofit retrofit = builder.client(httpClient.build()).build();
return retrofit.create(service);
}
public Retrofit retrofit() {
return getInstance().builder.client(getInstance().httpClient.build()).build();
}
}

这是处理OkHttp和改造的最微不足道的问题之一。实际上，我也在努力争取解决方案很长一段时间，直到我因为下面的代码块而导致错误。
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.BODY);
httpClient.addInterceptor(logging);
因此，一旦删除了线条，就应该正常工作。
