If you weren't following the Android scene before you got your HTC EVO 4G, then there's a good chance that this is the first time you're seeing these Android mascot app icons. And regardless of which ROM or home launcher you're using right now, there's an even better chance that you want these icons on your home screen.
They've actually been around since before the EVO was released, but since newer doesn't always mean better (don't forget that our EVOs are already 7 months old) and icons like these are timeless, let's just talk about how to get them onto your phone.
Thanks to the work of manup456 and animoo, there are a total of 181 icons that can be assigned to represent any app, folder, or shortcut on your EVO's home screen. Both xda-developers forum members released their icon packs separately, but I've gone ahead and just combined them into a single .zip for simplicity and ease of use.
The original icons can be found here:
The combined .zip can be found in the tutorial below.
1. Download the Android mascot icons (.zip).
2. Extract the .zip and move the "android-icons" folder to the root directory of your EVO's microSD card.
I personally use BetterCut, so here's the QR code and instructions on how to use it with these icons.
Installed Applications > Camera > tap "Change Icon" button.
Pick Picture > select "android-icons" folder > select desired icon > tap "Create" button.
Repeat as necessary.
Note that although you can use different apps to change the icons, which may be necessary if an app runs into problems with certain app shortcuts, the results may not be identical. For example, if you look closely at the first screenshot, you'll notice that background behind the "Battery" label is a little smaller than the other label backgrounds. That's because it was created with Desktop Visualizer; the rest were created with BetterCut.
If you use ADW.Launcher (and possibly other home launchers), then you don't need a third-party app to change the icon of your home screen shortcut. You can just long press an empty area of your home screen and select the "Custom Shortcut" option from the menu.
