Question

我是使用这个android库的新手，下面的代码是我简单的inslemented Retrofit库，运行项目后我没有得到任何错误，但我的项目挂断并且无法正常工作。

使用后的详细logcat消息Retrofit Call函数：

我的代码：

SignalProvider上课：

public class SignalProvider {
    private SignalServices signalServices;
    public SignalProvider(){
        OkHttpClient httpClient = new OkHttpClient();

        Retrofit retrofit = new Retrofit.Builder()
                 .baseUrl(ClientSettings.SignalWebBaseUrl)
                .client(httpClient)
                .addConverterFactory(GsonConverterFactory.create())
                .build();

        signalServices = retrofit.create(SignalServices.class);
    }
    public SignalServices getServices(){
        return signalServices;
    }
}

SignalServices接口类：

public interface SignalServices {
    @GET("storeLists")
    Call<List<Store>> getStoreLists();
}

ClientSettings上课：

public class ClientSettings {
    public static final String SignalWebBaseUrl = "http://192.168.1.35/signal/public/";
}

然后我通过这种方法从活动中使用它们：

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

    SignalProvider signalProvider = new SignalProvider();
    SignalServices signalServices = signalProvider.getServices();
    Store          store = new Store();

    Call<List<Store>> call = signalServices.getStoreLists();
    call.enqueue(new Callback<List<Store>>() {

        @Override
        public void onResponse(Call<List<Store>> call, Response<List<Store>> response) {

        }

        @Override
        public void onFailure(Call<List<Store>> call, Throwable t) {

        }
    });
}

运行项目后一段时间我的应用程序崩溃

Answer 1

解决了问题

在一些调试应用程序之后，我在Gradle上将targetSdkVersion从23更改为22，然后问题解决了

当我实现Retrofit2时Android应用程序挂起
