Retrofit HTTP method annotation is required

Question

I'm using retrofit 2.1, and when i call the @GET it says

HTTP method annotation is required (e.g., @GET, @POST, etc.).

Now.. if I define @retrofit.http.GET it throws

No Retrofit annotation found. (parameter #1)

With the @POST it's ok, it's works!

That's my error log for the HTTP method...

My interface:

 import okhttp3.ResponseBody;
 import retrofit2.Call;
 import retrofit2.http.Field;
 import retrofit2.http.FormUrlEncoded;
 import retrofit2.http.GET; 
 import retrofit2.http.POST;
 import retrofit2.http.Query;


 public interface Testapi {


    @GET("/getq.php")
    Call<Testmodel> getquery(
            @Query("sort") String order
    );


    @FormUrlEncoded
    @POST("/insert.php")
    Call<ResponseBody> insert(
            @Field("nick") String nick,
            @Field("mail") String mail
    );

}

And the method

private void getjson() {
    //Creating a rest adapter

    RestAdapter adapter = new RestAdapter.Builder().setEndpoint(ROOT_URL).build();

    //Creating an object of our api interface
    Testapi api = adapter.create(Testapi.class);
    Call<Testmodel> call = api.getquery("a");

    call.enqueue(new Callback<Testmodel>() {
        @Override
        public void onResponse(Call<Testmodel> call, Response<Testmodel> response) {
            try {
                Testmodel obj = response.body();

                TextView txt = (TextView) findViewById(R.id.textView);
                txt.setText("ID: " + obj.getId() + "   nick: " + obj.getNick() + "   mail: " + obj.getMail());

            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        @Override
        public void onFailure(Call<Gitmodel> call, Throwable throwable) {
            Toast.makeText(SignIn.this, "FALLIMENTO",     Toast.LENGTH_LONG).show();
        }
    });


}

Answer 1

First of all please check your imports in all clases which use Retrofit.

In your interface Testapi you use retrofit2 but in your method getjson() you're creating retrofit.RestAdapter instead of retrofit2.Retrofit which is definitly wrong.

Please resolve this issue and check if it is working.

PS. Here are very nice tutorials about migration from reftrofit 1.* to 2.*. Follow them and everything should working properly:

https://futurestud.io/tutorials/retrofit-2-upgrade-guide-from-1-9 https://inthecheesefactory.com/blog/retrofit-2.0/en

Why don't you use retrofit2 gradle dependencies directly from maven? - for example like in attached links.

Answer 2

@POST annotated method, must have parameter, marked as @Body
Example:

@POST("/user/mobile/verify")
VerifyCodeResponse verifyMobile(@Body VerifyRequest request);
