In Retrofit 2.0.0-beta2 you can use RequestBody and ResponseBody to post a body to server using String data and read from server's response body as String.

First you need to declare a method in your RetrofitService:

interface RetrofitService {
    @POST("path")
    Call update(@Body RequestBody requestBody);
}

Next you need to create a RequestBody and Call object:

Retrofit retrofit = new Retrofit.Builder().baseUrl("http://somedomain.com").build();
RetrofitService retrofitService = retrofit.create(RetrofitService.class);

String strRequestBody = "body";
RequestBody requestBody = RequestBody.create(MediaType.parse("text/plain"),strRequestBody);
Call call = retrofitService.update(requestBody);

And finally make a request and read response body as String:

try {
    Response response = call.execute();
    if (response.isSuccess()) {
        String strResponseBody = response.body().string();
    }
} catch (IOException e) {
    // ...
}
