Не запускается приложение через Android Studio

При попытке запустить приложение в Android Studio на реальном устройстве, приложение не устанавливается! Ну... Сначала устанавливается (антивирус пишет, что приложение проверено), а потом оно пропадает (так и не запустив Activity). Приложение — Hello World. В Eclipse все работало нормально.
Вот вывод в консоль:

Как исправить?
