Create and Manage Virtual Devices
Portrait - Oriented taller than wide. - Landscape - Oriented wider than tall.
An option is enabled only if it’s selected in the hardware profile. When running the AVD in the emulator, you can change the orientation if both portrait and landscape are supported in the hardware profile.

To enable a camera, select one or both options:

- Front - The lens faces away from the user. - Back - The lens faces toward the user.
The Emulated setting produces a software-generated image, while the Webcam setting uses your development computer webcam to take a picture.

This option is available only if it's selected in the hardware profile; it's not available for Wear OS and Android TV.

Select a network protocol to determine the speed of data transfer:

- GSM - Global System for Mobile Communications
- HSCSD - High-Speed Circuit-Switched Data
- GPRS - Generic Packet Radio Service
- EDGE - Enhanced Data rates for GSM Evolution
- UMTS - Universal Mobile Telecommunications System
- HSDPA - High-Speed Downlink Packet Access
- LTE - Long-Term Evolution
- Full (default) - Transfer data as quickly as your computer allows.

Select how graphics are rendered in the emulator:

- Hardware - Use your computer graphics card for faster rendering Android .
- Software - Emulate the graphics in software, which is useful if you're having a problem with rendering in your graphics card.
- Automatic - Let the emulator decide the best option based on your graphics card.

- Cold boot - Start the device each time by powering up from the device-off state.
- Quick boot - Start the device by loading the device state from a saved snapshot. For details, see Run the emulator with Quick Boot.

Create an emulator skin

An Android emulator skin is a collection of files that define the visual and control elements of an emulator display. If the skin definitions available in the AVD settings don't meet your requirements, you can create your own custom skin definition, and then apply it to your AVD.

Each emulator skin contains:

- A hardware.ini file
- Layout files for supported orientations (landscape, portrait) and physical configuration
- Image files for display elements, such as background, keys and buttons

To create and use a custom skin:

1. Create a new directory where you will save your skin configuration files.
2. Define the visual appearance of the skin in a text file named layout. This file defines many characteristics of the skin, such as the size and image assets for specific buttons. For example:

parts device display width 320 height 480 x 0 y 0 portrait background image background_port.png buttons power image button_vertical.png x 1229 y 616 ...
3. Add the bitmap files of the device images in the same directory.
4. Specify additional hardware-specific device configurations in a hardware.ini file for the device settings, such as hw.keyboard and hw.lcd.density.
5. Archive the files in the skin folder and select the archive file as a custom skin.

For more detailed information about creating emulator skins, see the Android Emulator Skin File Specification in the tools source code.
