Android - Timed out after 300seconds waiting for emulator to come online

Hola a todos,

He actualizado android studio 2.1.2 y mi desktop es un lenovo intel core i5-3470 CPU @ 3.2 GHz, sistema operativo windows 8 64 bits.

bien creando un simple proyecto, solo el activity principal y queriendo ejecutar dicha aplicacion con el emulador (AVD Manager) me genera el siguiente error:

Error while waiting for device: Timed out after 300seconds waiting for emulator to come online

utilizando 1024 mega para la memoria RAM y para la heap.

Saludos.

I am also facing the same issue. Android apps launched successfully. But I am getting "Error while waiting for device: Timed out after 300seconds waiting for emulator to come online."

How to solve this error?

I am using AndroidStudio 2.2, jdk1.8.0_66

Thanks for your help in advance.
