icon: yellow is poorly visible on white

I think yellow on white is good enough. However, the white rectangle on white background is not ideal. What would you suggest as improvement? Could you make a pull request?

#165 is about the white rectangle. But this yellow is really poorly visible and shadow makes it dirty.

The improvement is easy:

0. Choose a bit darker yellow color
   At least with 2.0 ratio, if you'd like to leave white:
   https://contrastchecker.com/?c=FFFFFF&b=e2ad00
   Rithgt now it's 0xededed/0xfbce17 that has a very low contrast ratio: 1.29.

1. Make a flat yellow color adaptive foreground.

2. Remove shadow

3. Put current symbols in white color on the foreground.

I'd be happy to make a PR, but I have no android studio (I heard that it's required for the easiest adaptive icons creation) or even an android build env.

OK, I've installed android studio, and Image Asset says "Project must be built with SDK 26 or later to use adaptive icons"

Is it easy to upgrade it?

Could you also point me to the current icons in svg?

they come from the default android icon set. remote-reader icon was generated as follows:
https://romannurik.github.io/AndroidAssetStudio/icons-launcher.html#foreground.type=clipart&foreground.clipart=res%2Fclipart%2Ficons%2Fnotification_tap_and_play.svg&foreground.space.trim=0&foreground.space.pad=0.25&foreColor=rgb(0%2C%200%2C%200)&backColor=rgb(0%2C%200%2C%200)&crop=0&backgroundShape=hrect&effects=shadow&name=ic_launcher
ACardEmulator's icon only changes the symbol
