I got "Error: No Retrofit annotation found. (parameter #2)" while using this code. Please help me. Thanks in advance.
使用此代码时，我收到“错误：未找到改造注释。（参数 #2）”。请帮我。提前致谢。

Try this code
试试这个代码
Api Services
接口服务
@POST("/api/employee/checkin")
Call<Sample> CHECKIN(@Body JSONStringer data);
API Client
API客户端
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.addInterceptor(new Interceptor() {
@Override
public Response intercept(Interceptor.Chain chain) throws IOException {
Request original = chain.request();
// Request customization: add request headers
Request.Builder requestBuilder = original.newBuilder()
.addHeader("Content-Type", "application/json")
.addHeader("x-access-token", "eyJhbGci");
Request request = requestBuilder.build();
return chain.proceed(request);
}
});
OkHttpClient client = httpClient.build();
return new Retrofit.Builder()
.baseUrl(ROOT_URL)
.client(client)
.addConverterFactory(GsonConverterFactory.create())

use GSON lib
使用 GSON 库
add this dependency in build.gradle
在 build.gradle 中添加此依赖项
compile 'com.google.code.gson:gson:2.8.0'

When using the @FormUrlEncodedannotation, pass parameters using the @Fieldparam instead of @Body. Hence do this:
使用@FormUrlEncoded注解时，使用@Fieldparam 而不是@Body. 因此这样做：
@FormUrlEncoded
@Headers({
"Content-Type: application/json",
"x-access-token: eyJhbGciOiJIU"
})
@POST("/api/employee/checkin")
Call<String> CHECKIN(@Field("data") String data);
I have assumed your server expects a datakey which will have the details. If it is something else, please change it in here @Field("data")
我假设您的服务器需要一个data包含详细信息的密钥。如果是别的东西，请在这里更改@Field("data")
EDIT:
编辑：
Based on the comments:
根据评论：
@FormUrlEncoded
@Headers({
"Content-Type: application/json",
"x-access-token: eyJhbGciOiJIU"
})
@POST("/api/employee/checkin")
Call<String> CHECKIN(@Field("logTime") String logTime, @Field("datas") String datas);

Have you added RetroFit to build.gradle ?
你有没有将 RetroFit 添加到 build.gradle ？
