android - Corona SDK: Bottom Banner Ad Not Showing -

i'm developing android app ads in corona sdk using admob when try display ad @ bottom of screen setting y 100000 ad doesn't show @ all. shows @ top of screen when y = 0. here code:

local ads = require( "ads" ) local bannerappid = "the app id" local adprovider = "admob" local function adlistener( event )  end ads.init( adprovider, bannerappid, adlistener )  ads.show( "banner", { x=0, y=100000, appid=bannerappid } ) 

please help! thanks!

assuming have setup admob account , app properly, make sure add build.setting file:

settings = {     plugins =     {         ["plugin.google.play.services"] =         {             publisherid = "com.coronalabs"         },     },       }
