Looking at how to add splash screens in different resolutions, I gave the method a shoot with Icons.
I added the intended xxxhdpi icon bitmap file to the [projectname]\Build\Android\res\drawable-xxxhdpi path. Build the project to Android successfully. Opened the resulting APK file, and confirmed that both the xxhdpi and xxxhdpi icons were now present in the APK file. However this did not result in them being utilized when the APK was installed on test devices.
I’m again at a loss at how to make the higher resolution icons work on Android. Any thoughts or suggestions in relation to this problem would be appreciated.
