Android and iOS xml

Hi,

I have my xml file for my android and iOS device. I am fine with what needs to be in the iOS bits but I am new to Android.

I know permissions are needed, but is there anything else that is a must? Any pitfalls that I may slip into?

I have these icon sizes too:

<image48x48>testAppIcon48.png</image48x48>

<image72x72>testAppIcon72.png</image72x72>
