在Mac OS X上运行Android Studio模拟器的问题

Question

I successfully installed Android Studio on my Macbook Pro 8 Go memory under OS X El Capitan.I created a simple Hello World app and then I tried to run the app, I was asked to create an AVD and chose Nexus 5 x config with x86. The device was created after downloading the image file and I ran the App. The Gradle process ran well and the app launched the emulator

I got the following message in the app window :

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

The emulator showed only the word "Android" . The emulator has been running for a long time (more than 30 mn)

Below you'll find a very small extract of the emulator error window.

Answer 1

As cricket_007 suggested in the comment, it is generally suggested to use Genymotion or something similar since they're so much better.

Apart from that, if you're keen on running the emulator that comes with AS, you might also want to get Intel HAXM (Hardware Accelerated Execution Manager) driver from Android Package Manager. It provides hardware acceleration, but the benefits vary device to device.
