+|android.enableAdaptiveIcons
+|Boolean true/false defaults to false. Enables Android adaptive icon generation in Android Gradle builds. When enabled, Codename One generates `mipmap` launcher resources (`ic_launcher`, `ic_launcher_foreground`, and adaptive XML in `mipmap-anydpi-v26`) and uses them in the application manifest (`android:icon` and `android:roundIcon`).

+|android.adaptiveIconBackground
+|Background color to use for adaptive icons when `android.enableAdaptiveIcons=true` and no background image is supplied. Defaults to `#ffffff` and is written as `@color/ic_launcher_background`.
+
+|android.adaptiveIconBackgroundImage
+|Optional path (relative to the root of the native Android project) to an image file to use as the adaptive icon background when `android.enableAdaptiveIcons=true`. If this property is set, it overrides `android.adaptiveIconBackground`.

 |Applies to any number of layouts as long as they are in sequence (e.g. android.cusom_layout2, android.cusom_layout3 etc.). Will write the content of the argument as a layout xml file and give it the name `cusom_layout1.xml` onwards. This can be used by native code to work with XML files
