Error while starting android emulator: FB::flushWindowSurfaceColorBuffer: window handle 0x4 not found

Question

I just started working with android. So when i try to start the AVD (details below) it doesn't start, just a black screen for a time, until I get tired of it and shut it down. I have intelhaxm installed, and hyper-v disabled.

This is the log i got form the console:

AVD specifications:

Answer 1

Here's the deal. Host GPU is only supported for AVD devices that are using API 15 or later. You also have to have Android SDK Tools 17 or later installed. Also Host GPU is experimental. All of this is in the emulation documentation: http://developer.android.com/tools/devices/emulator.html

Also your machine has to support OpenGL (most do) and you will get better results if your machine has a separate GPU even though it will work with integrated graphic chipsets as well.

If you cannot take advantage of Host GPU then use the Snapshot option instead to gain some performance boost. This will take a snapshot of the ram on the initial start of the emulated device and then reuse it on initial boot start ups of the device. (Snapshot and Host GPU are actually mutually exclusive even though the ADV allows you to check both.)
