Hi, I’ve set my push notification icon to my logo, however, a [white] circle appears instead.
What am I doing wrong here?
AI-generated summary
The discussion revolves around Android push notification icon requirements. nexo encountered an issue where a white circle appears instead of their logo. The solution, provided by Falco, is that the icon must be monochromatic with a white color on an alpha background, as stated in the Android 5.0 changes documentation.
featheredtoast offered a step-by-step guide on how to convert an icon to a transparent monochrome image using GIMP. The process involves desaturating the image by luminosity, adding transparency, and inverting the colors. nexo successfully applied the solution using LunaPic.
I thought of an idea: Is it a circle because Android doesn’t distinguish notification icons (just generalizes all icons to be white), so the green lines should actually be transparent?
That icon is tricky.
It must be monochromatic, only white on alpha background.
For reference, the quick overview to to convert an icon to a transparent monochrome image in GIMP:
desaturate by luminosity (converts to black+white), layer → transparency → color to alpha (adds transparency), and finally invert colors (flips to white)
The same methods should work on photoshop or your image editor of choice.
I was able to do it in LunaPic.
I’m a little confused how this function works! 
Hey Eduardo, this has been resolved here, and I don’t understand what you are asking for. Can you start a new topic about your issue, and give some details please?
