Create your own skin for Genymotion Desktop

2024-04-24

To create a custom skin, you need the following elements:

All these elements have to be put in a new folder in:

For example:

Background image The background image must be in PNG format and it must be named background.png.

JSON File Then you need to create a JSON file named skin.json, which contains the following information.

Name "name": "string" This attribute allows you to give a name for your skin. After creation, you should find your skin in the Virtual device installation window if you want to create a new device with this skin:

Display "display": { "offset": { "x": int, "y": int }, "size": { "width": int, "height": int } }

The display attribute sets the size and offset of your skin. offset This parameter sets the offset between your skin and the device display. size This parameter sets the width and height of the virtual device resolution.

Important The height and width of the background image must not be lower than height + offset x and width + offset y, or your skin will not be valid and you will get a BACKGROUND_FORMAT_ERROR error.

Resize Margins "resizeMargins": { "left": int, "top": int, "right": int, "bottom": int }

The resizeMargins attribute defines the resizable margins of the window. Note that the window will only be resizable from bottom and left sides, but you still need to define the other sides in case the virtual device is rotated.

Example

Content of the skins folder: ~/.Genymobile/Genymotion/skins/skin-test/ ├── background.png └── skin.json

Content of skin.json: { "name": "skin-test", "display": { "offset": { "x": 150, "y": 150 }, "size": { "width": 720, "height": 1280 } }, "resizeMargins": { "left": 75, "top": 75, "right": 75, "bottom": 75 } }

Here is a diagram explaining precisely each parameter from skin.json:

To illustrate how the folder and files are organized, here is a simple example structure:

Content of the skins folder:

~/.Genymobile/Genymotion/skins/skin-test/

Content of skin.json: { "name": "skin-test", "display": { "offset": { "x": 150, "y": 150 }, "size": { "width": 720, "height": 1280 } }, "resizeMargins": { "left": 75, "top": 75, "right": 75, "bottom": 75 } }
