我使用 RoboSpice-Retrofit 调用我的服务器 REST api，直到几天前它一直没有问题，现在每次调用都会抛出异常，示例:

D/Retrofit: java.lang.NoSuchMethodError: No direct method <init>(Lcom/squareup/okhttp/OkHttpClient;Lcom/squareup/okhttp/Request;ZZZLcom/squareup/okhttp/Connection;Lcom/squareup/okhttp/internal/http/RouteSelector;Lcom/squareup/okhttp/internal/http/RetryableSink;Lcom/squareup/okhttp/Response;)V in class Lcom/squareup/okhttp/internal/http/HttpEngine; or its super classes (declaration of 'com.squareup.okhttp.internal.http.HttpEngine' appears in /data/app/com.company.app.customerapp-1/base.apk)

D/Retrofit: ---- END ERROR

依赖关系:

compile 'com.octo.android.robospice:robospice:1.4.14'
compile 'com.octo.android.robospice:robospice-cache:1.4.14'
compile 'com.octo.android.robospice:robospice-retrofit:1.4.14'

我怀疑基于异常是编译器有问题，但我只是在另一台计算机上测试，在同一个项目上全新安装了 Java 和 Android Studio，但同样的问题仍然存在......

这个错误快把我逼疯了...

有谁知道有什么可以帮助的吗？非常感谢任何帮助。

编辑

MainActivity.java:

SpiceManager spiceManager = new SpiceManager(TestAPIService.class);

protected void onStart() {
    super.onStart();

    spiceManager.start(this);

    spiceManager.execute(new TestRequest(), new RequestListener<ResponseData>() {
        ...
    });
}

TestAPIService.java:

public class TestAPIService extends RetrofitGsonSpiceService {

    @Override
    public void onCreate() {
        super.onCreate();
        addRetrofitInterface(TestAPI.class);
    }

    @Override
    protected String getServerUrl() {
        return "http://192.168.0.2";
    }
}

TestAPI.java:

public interface TestAPI {
    @GET("/test")
    ResponseData getTest();
}

TestRequest.java:

public class TestRequest extends RetrofitSpiceRequest<ResponseData, TestAPI> {

    public TestRequest() {
        super(ResponseData.class, TestAPI.class);
    }


    @Override
    public ResponseData loadDataFromNetwork() throws Exception {
        ResponseData response;

        try {
            response = getService().getTest();
        }
        catch (Exception e) {
            e.printStackTrace();
            throw e;
        }

        return response;
    }
}

最佳答案

NoSuchMethodError 的发生是因为 HttpURLConnectionImpl 试图在 HttpEngine 上调用未定义的构造函数。现在您的项目取决于:

com.octo.android.robospice:robospice-retrofit:1.4.14

哪个depends on :

com.squareup.retrofit:retrofit:1.6.1

哪个depends on两者:

com.squareup.okhttp:okhttp:2.0.0

and

com.squareup.okhttp:okhttp-urlconnection:2.0.0

从版本 2.0.0 开始，HttpURLConnectionImpl 在 okhttp-urlconnection 模块中，而 HttpEngine 在okhttp 模块。 堆栈跟踪的 retrofit.client.UrlConnectionClient 部分正确匹配 retrofit:1.6.1 ，但 com.squareup.okhttp.internal.huc.HttpURLConnectionImpl 部分与 okhttp-urlconnection:2.0.0 不匹配;它匹配 okhttp-urlconnection:2.4.0 . NoSuchMethodError 提示的构造函数确实在 okhttp:2.4.0 中定义，所以这意味着您的类路径上有一个不同的 HttpEngine，很可能来自不同版本的 okhttp，它被传递依赖性引入。您应该能够通过指定以下依赖项来解决问题:

compile('com.squareup.okhttp:okhttp:2.0.0') {
    force = true
}
compile('com.squareup.okhttp:okhttp-urlconnection:2.0.0') {
    force = true
}

如果出于某种原因这不起作用，您的问题的解决方案仍然是让您的 okhttp 和 okhttp-urlconnection 版本同步与您的 retrofit 版本兼容的版本。与上面类似声明依赖项，找到包含 HttpURLConnectionImpl 和 HttpEngine 的 jar，figure out how they're getting pulled in to your build ，并使用 exclusions摆脱有问题的传递依赖。
