How to create your own skin in Genymotion Desktop?

Genymotion Desktop supports skins and comes with a set of 4 default skins (2 phones & 2 tablets).

However you can design and use your own custom skin. To do so, you will need:

1. A background image (background.png)
2. A JSON file (skin.json)

All these elements have to be put in a new folder in ~/.Genymobile/Genymotion/skins (Linux, macOS) or %LOCALAPPDATA%\Genymobile\Genymotion\skins(Windows).

For example, ~/.Genymobile/Genymotion/skins/my-phone-skin/ or %LOCALAPPDATA%\Genymobile\Genymotion\skins\my-phone-skin\.

Background image

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

For example:

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.

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 parameters from skin.json:
