How To Handle Jsonsyntaxexception When Receiving Response From Gae

Solution 1:

The problem here is that you are trying to send a POST with the "name" parameter as a @Query, when you should be sending as a @Field.

@FormUrlEncoded@POST("/hello")

Solution 2:

You're returning a plain text response, and from the error message I assume Retrofit expects a JSON formatted response. Either:

• try changing resp.setContentType("text/plain"); to resp.setContentType("application/json"); and change the content to JSON format

• or check this question to read the string from the response: Retrofit callback get response body
