Android icon generator for actionbar and notification not working (grey shape)

I think it's because your image is too complexe and the main problem is the "color" filter applied in AAS.

I had the same problem and I had to convert xxxhdpi xxhdpi etc. manually. If you work with Sketch (for example) it can be converted easily with a plugin (https://github.com/zmalltalker/sketch-android-assets)

hope it's help !

If you want to use AAR, like @rom4ek explained "4. Move foreground color thumb to 0%" this is the important part

You can use a tool for creating generic icons in Asset Studio: https://romannurik.github.io/AndroidAssetStudio/icons-generic.html. To get it look like ActionBar Icon, you should make next actions:

1. Choose image
2. The size of image should stay at 24dip
3. Change padding to 4dip
4. Move foreground color thumb to 0%
5. That's it! Download .zip now.

The sizes of icons will be pretty the same as you can get them with ActionBar Icon Generator.

How it looks for me:

Use this instead https://romannurik.github.io/AndroidAssetStudio/icons-generic.html

Here demonstrating how to show the image:

1. upload your image
2. set the foreground color to 0, just like below

I use an own module 'icons' with a Gradle script to generate icons. This is a more automated way than the Assets Studio can provide up-to-now. The icon will be designed with Inkscape. See my blog for a detailed description. You find an Android Studio Project on GitHub.
