// Get help about disk images relevant to app developers. It explains where the image files are located for an AVD created with the SDK tools. For example:
emulator -help-sdk-images

	
// Disable graphical window display on the emulator. This option is useful when running the emulator on servers that have no display. You'll still be able to access the emulator through adb or the console. For example:
emulator @Nexus_5X_API_23 -no-window
