Есть рабочий проект.
Жму Run, выбираю эмулятор "Nexus 5"
И получаю сообщение об ошибке:
Cannot launch AVD in emulator.
Output:
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: HAX kernel module is not installed!
