Retina iconLink with Google Drive API

Question

I'm an getting a list of files in a folder. The response contains a iconLink for every file returned. This icon is 16x16 pixels.

Does anyone know a way to retrieve a retina image? Or another way to retrieve a bigger icon image?

The good news is although not officailly documented driver does have 2x resolution icons. The bad news is they have inconsistent file names; for example the icon you linked in the comments has a 32px version availabel here: ssl.gstatic.com/docs/doclist/images/mediatype/icon_3_pdf_x32.png

Now here is my soltion, it's not perfect but it will do the job for a while:

function getIcons($file_type)
{ 
    $icons = [
        'pdf' => [
            'icon' => 'icon_12_pdf_list.png',
            'retina' => 'icon_3_pdf_x32.png'
         ],
        'document' => [
            'icon' => 'icon_1_document_x16.png',
            'retina' => 'icon_1_document_x32.png'
        ],
        'image' => [
            'icon' => 'con_1_image_x16.png',
            'retina' => 'icon_1_image_x32.png'
        ],
        'word' => [
            'icon' => 'icon_1_word_x16.png',
            'retina' => 'icon_1_word_x32.png'
        ],
        'text' => [
            'icon' => 'icon_1_text_x16.png',
            'retina' => 'icon_1_text_x32.png'
        ],
        'spreadsheet' => [
            'icon' => 'icon_1_spreadsheet_x16.png',
            'retina' => 'icon_1_spreadsheet_x32.png'
        ],
        'form' => [
            'icon' => 'icon_2_form_x16.png',
            'retina' => 'icon_2_form_x32.png'
        ],
        'audio' => [
            'icon' => 'icon_1_audio_x16.png',
            'retina' => 'icon_1_audio_x32.png'
        ]
    ];

    return isset($icons[$file_type]) ? $icons[$file_type] : $icons['text'];
}

The reasion I say it will work for a while is that I'm asuming the _3_ in pdf icon file name for instance is the version number. So if Google updates it's icons again in the future this solution may brake.

I'm using drive rest api and what i observed was that iconLink attribute had a definite pattern. "https://drive-thirdparty.googleusercontent.com/" + size + mimetype By default size is 16. So, before adding your icon to Image, use this:

    String iconLink = (String) jsonObject.get("iconLink");
    iconLink=iconLink.replace("16","128");
