Implementing own AdMob plugin layout adview wrapper choice

Hi,

I’m very new to Android SDK development and now implementing my own AdMob plugin. I was wondering what layout is best to use to wrap the AdView with? Corona returns a frame layout if you call getOverlayView().  

The original AdMob Corona plugin allows specification of coordinates for banner positioning. Under the hood an absolute layout class is probably used. Is there a technical benefit to using absolute layout versus frame layout class? I’m not interested in being able to position the banner at specific coordinates. I simply want to position the banner either at the top or the bottom, and maybe shift it to the right or left. 

Is there a device compatibility reason at play here where a particular layout type may work better across more device types or older android SDK APIs perhaps?

Thank you.
