Question

My Model

public class ModelMessage {
    private String message;
    public String getMessage() {
        return message;
    }
}

My Interface

public interface Noqta {
    @GET("api/")
    Call<ModelMessage> message();
}

My Call on Activity click

Retrofit retrofit = new Retrofit.Builder()
                .baseUrl("http://noqta.tk/")
                .addConverterFactory(GsonConverterFactory.create())
                .build();
        Noqta noqta = retrofit.create(Noqta.class);
        Call<ModelMessage> call = noqta.message();
        call.enqueue(new Callback<ModelMessage>() {
            @Override
            public void onResponse(Call<ModelMessage> call, Response<ModelMessage> response) {
                if(response.isSuccessful()){
                    tv.setText("True");
                }else{
                    tv.setText("False");
                }
            }
            @Override
            public void onFailure(Call<ModelMessage> call, Throwable t) {
                tv.setText("Error");
            }
        });

json body on noqta.tk/api

{"message":"Hello World from api web"}

What i am doing bad? I have internet permission on manifest

Answer 1

Add these two lines to your build.gradle in the android section:

android{
    compileOptions {
            sourceCompatibility 1.8
            targetCompatibility 1.8
    }
}

can someone explain to me why this is the solution? I see that the error is in:

.baseUrl("http://noqta.tk/")
