Appcelerator - androdi.support.v4

Когда я компилирую проект, появляется эта ошибка:

[ERROR] :  Failed to compile Java source files:

Я понятия не имею, что происходит...

Это проект appcelerator (сплав), поэтому я не могу добавить библиотеку (.jar) в проект, я думаю.

Пожалуйста, помогите мне Спасибо.
