private interface ResourcesApi {
        @POST("/synchronize")
        void getResources(@Body Map<String, Map<String, Object>> map,
                          Callback<DataModel> callback);
    }

调用代码：

mApi.getResources(data, this);

该类实现了回调，因此定义了成功/失败。

It means the @POST annotation can't be found at runtime. Without the HTTP method type (and relative URL it contains), Retrofit cannot make the request.

Are you using Proguard or another tool to trim "unused" code? If so, instruct it to keep Retrofit's annotations.

除了 Jake 的回答之外，这是我必须添加到我的proguard文件中才能使其正常工作的内容：

-keep class com.google.gson.** { *; }
-keep class com.google.inject.** { *; }
-keep class org.apache.http.** { *; }
-keep class org.apache.james.mime4j.** { *; }
-keep class javax.inject.** { *; }
-keep class retrofit.** { *; }

同意@chad 的回答，如果仍然崩溃，请添加以下行。

-keepattributes Signature
-keep class sun.misc.Unsafe { *; }
