App tile transparency for WP8.1 apps #wpdev

One of my popular lines is “Don’t throw shit around.. what goes around comes around!” and rightly so. A few weeks back I was making fun of @dvlup for blogging about how to create transparent tiles for the WP apps🙂

I know the irony isn’t lost on me. The idea is with WP8 apps, you create tile images which are transparent png with white bits.. if you had a star or a clock that would be white, the rest would be transparent and you used this. This would make your app’s tile transparent and if you had a fancy background, you would see through the tile.

Fast forward today, I was testing WP8.1 update to my alarm clock app. What does it do ? well shows you tile update every minute with a nicely rendered tile. and yes I made the tile transparent. But the tile comes up as grey.. WTH

so I start looking around and I remember that Windows 8 app manifest had a background color, Open the Package.appmanifest and I find this

<m3:VisualElements
    DisplayName="AlarmClock"
    Square150x150Logo="Assets\SquareTile150x150.png"
    Square44x44Logo="Assets\Logo.png"
    Description="AlarmClock"
    ForegroundText="light"
    BackgroundColor="#464646">

hmmm no alpha value to make it transparent. So I tried to set BackgroundColor to Transparent.. nope.. transparent ? Bingo!!

<m3:VisualElements
    DisplayName="AlarmClock"
    Square150x150Logo="Assets\SquareTile150x150.png"
    Square44x44Logo="Assets\Logo.png"
    Description="AlarmClock"
    ForegroundText="light"
    BackgroundColor="transparent">

Now if you used transparent png for tiles, your WP 8.1 app’s tiles are transparent.
