Проблемы с запуском / отладкой примеров кода Android Mapbox

Question

Я пытаюсь начать работу с mapbox android и не могу заставить работать ни один из примеров проектов.

Моя проблема с импортом

import android.support.annotation.NonNull;
import android.support.v7.app.AppCompatActivity;
import com.mapbox.mapboxandroiddemo.R;

Я получаю "не может разрешить символьную аннотацию "," не может разрешить символ v7 "и" не может разрешить символ mapboxandroiddemo ".

Я чувствую, что это какая-то проблема с андроидом, которую я просто не понимаю правильно, поэтому, если у кого-то есть понимание, которое было бы удивительным.Я попытался извлечь некоторый код и использовать рекомендуемые исправления ошибок, но все, что сделал, это сломал мой проект.

Вот весь файл MainActivity.java
