Answer 1

GO TO: -

Project> Properties> Java Построить Path> Заказать & Экспорт и проверить, если все библиотеки, что ваш проект с помощью проверяется или нет.

Answer 2

Может быть, потому, что класс MenuActivity.java не объявлен:

записи общественного класса HomeActivity расширяет активность {

перед тем

@Override защищен недействительным OnCreate (Bundle savedInstanceState) {

Answer 3

Под ярлыком манифеста ваш пакет

 package="com.loco.android" 

Но ваша пусковая деятельность имеет

 com.sit.loco. 

Можете ли вы expalin это ??
