Android Question Gray icon in Notifications

Hello everyone! I faced such a problem: on some devices and the emulator the notification icon is gray, while on my phone (HONOR 9X) the icon is colored and everything is fine. I also used the class Notification, and now I use NB6. Nothing has changed, can anyone have encountered such a problem?

Best regards

Hello, thanks.

I did everything according to the guide and I get an error when compiling:

res\mipmap-anydpi\ic_launcher.xml: error: <adaptive-icon> elements require a sdk version of at least 26.

I have this string in my manifest:
B4X:
<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="30"/>
If I change the minimum version to 26, what is the risk?
if i change version i get error: failed linking file resources.

the files are in the root directory, if I put them in the "res" folder, then they are deleted during compilation

Before Android 6 or 7 you could use multi-color notification icon. After that only gray or white on transparent background. PNG 32bit.
The icon can be independent from the normal program colored icon.
But I will follow the link and check if I can do it.

I followed this post: https://www.b4x.com/android/forum/t...mple-instructions-and-tips.123843/post-788829 #24.
So use that online tool, it creates all needed icons except notification, and do as posted at #24. Also the part you have to copy into the manifest editor.
Then I noticed that in folder \Objects\res\drawable\ , there is where your notification icon.png (32bit 128x128 PNG alpha background, white foreground) has to be stored. If you leave it empty, B4A will copy it's own icon.png to it when build the app.
------------------
Also noticed that if B4A detects an error in manifest, and after you corrected, it still encounters the same error. Restart B4A an build again. Then it works.
I saw this wehn I was tryig to use icons generated by Android Studio, it read xml files and argued about color folder which was not used and not in icon folders at all.
So next I tried the above solution. It works, but no other color than white.
