Adding to Julien's answer, also remove the @Multipart annotation. Here's how I have used it:

@POST("/app/oauth/token")
Call getAuthToken(@Body RequestBody body);

And, here is how I have constructed the RequestBody:

RequestBody requestBody = new MultipartBody.Builder()
                        .setType(MultipartBody.FORM)
                        .addFormDataPart("grant_type", "password")
                        .addFormDataPart("username", username)
                        .addFormDataPart("password", password)
                        .build();
