HAXM executes most CPU instruc‐ tions natively in the processor, so this option enables OpenGL to be accelerated by the host GPU. Do not select the Snapshot option.
This can be anything you like, but you should choose a name that lets you identify the specific options offered by the AVD. , Galaxy‐ Nexus, SamsungS4, or HTCOne.
