Android 错误：IllegalArgumentException:无法为2创建调用适配器。响应
我通过本教程（）创建了一个AcceleratorRESTAPI，只是为了在端点（）处查看本地主机服务器上的数据值。但我面临一个错误“无法为2.Response创建调用适配器” 然而，在使用教程改型（<2.0）时，我使用的是RetroFit2.0（2.1）。因此，根据更新的库所做的更改很少 这是我下面的Accelerometer.javaAndroid 错误：IllegalArgumentException:无法为2创建调用适配器。响应,android,retrofit2,android-sensors,restful-architecture,Android,Retrofit2,Android Sensors,Restful Architecture,我通过本教程（）创建了一个AcceleratorRESTAPI，只是为了在端点（）处查看本地主机服务器上的数据值。但我面临一个错误“无法为2.Response创建调用适配器” 然而，在使用教程改型（

Call<Acceleration> sendAccelerationValues(@Body Acceleration acceleration);
}
改装：
Retrofit rest = new Retrofit.Builder()
.baseUrl(endpoint)
.addConverterFactory(GsonConverterFactory.create())
.build();
我想，我可以帮你
简短回答：在Accelerometrapi
界面中返回Call
public interface AccelerometerAPI {
@POST("/acceleration")
Call<Acceleration> sendAccelerationValues(@Body Acceleration acceleration);
}
然后像这样建造改装：
Retrofit rest = new Retrofit.Builder()
.baseUrl(endpoint)
.addConverterFactory(GsonConverterFactory.create())
.build();
