Error in ad placement!

Getting Started Newbie Questions
#1

I am trying to put ads in my game and it seems something went wrong. I have attached a screen shot of it.

It says attempt to call a nil value and more.I have studied updated star explorer project and added the code as it says in the main.lua file. I am not wanting to build game for ios and don’t want to put ads  for it.The code in build file and then main.lua is as followed. 

settings = { orientation = { -- Supported values for orientation: -- portrait, portraitUpsideDown, landscapeLeft, landscapeRight default = "portrait", supported = { "portrait", }, }, plugins = { ["plugin.coronaAds"] = { publisherId = "com.coronalabs", supportedPlatforms = { iphone=true, android=true } }, ["plugin.google.play.services"] = { publisherId = "com.coronalabs", supportedPlatforms = { android=true } }, ["shared.android.support.v4"] = { publisherId = "com.coronalabs", supportedPlatforms = { android=true } }, } excludeFiles = { -- Include only the necessary icon files on each platform iphone = { "Icon-\*dpi.png", }, android = { "Icon.png", "Icon-Small-\*.png", "Icon\*@2x.png", }, }, -- -- iOS Section -- iphone = { plist = { UIStatusBarHidden = false, UIPrerenderedIcon = true, -- set to false for "shine" overlay --UIApplicationExitsOnSuspend = true, -- uncomment to quit app on suspend CFBundleIconFiles = { "Icon.png", "Icon@2x.png", "Icon-167.png", "Icon-60.png", "Icon-60@2x.png", "Icon-60@3x.png", "Icon-72.png", "Icon-72@2x.png", "Icon-76.png", "Icon-76@2x.png", "Icon-Small.png", "Icon-Small@2x.png", "Icon-Small@3x.png", "Icon-Small-40.png", "Icon-Small-40@2x.png", "Icon-Small-50.png", "Icon-Small-50@2x.png", }, }, }, -- -- Android Section -- android = { usesPermissions = { "android.permission.INTERNET", }, }, }

composer.gotoScene( "menu" ) local coronaAds = require( "plugin.coronaAds" ) local apiKey = "myapikeyno" -- Corona Ads listener function local function adListener( event ) -- Successful initialization of Corona Ads if ( event.phase == "init" ) then composer.setVariable( "coronaAdsInitialized", true ) end end coronaAds.init( apiKey, adListener )
#2

Which line is line 15? I count 11 lines. Also corona ads don’t work in simulator.

#3

Does that explain the plugin.coronaads warning I get in the simulator?

#4

Many of the plugins only work on device and in the simulator you get a warning like:

WARNING: The PluginName plugin is only supported on Android & iOS devices. Please build for device

This is because the plugin is using an SDK and that vendor only made the plugin for mobile device operating systems. Windows and macOS are not mobile device operating systems and there is no SDK available. Instead of getting errors preventing your app from working we download “stub” plugins that have all the API calls, but they emit the message. This lets  you continue to use the simulator for other things but when you need to test those specific features you have to build for the device.

Here is it! Please help!

Can you humor me and rewrite your code to be:

local coronaAds = require( "plugin.coronaAds" ) display.setStatusBar( display.HiddenStatusBar ) local apiKey = "e2f23154-3095-43cd-95e7-2c036c21c06f" -- Corona Ads listener function local function adListener( event ) -- Successful initialization of Corona Ads if ( event.phase == "init" ) then composer.setVariable( "coronaAdsInitialized", true ) end end coronaAds.init( apiKey, adListener ) -- include the Corona "composer" module local composer = require "composer" -- load menu screen composer.gotoScene( "menu" )

Also what is your build.settings file?

Are you getting any more messages in your console log (the window that opens behind your simulator)?

What version of Corona are you using?

Hi, but the code you provided is still not working and system is getting the same error. I am using v2016.2906 version of corona simulator.Also I have attached screen shot of console log and it is displaying same error as simulator. The code of build.settings file is…

My build.settings(top) and my main.lua(bottom). This worked perfectly fine for me.

Where have you tried using the ad? Corona’s errors like all other errors are never 100% accurate. Post the code where you tried using the ad.

 } --\<------- you need a comma here excludeFiles =

You need to add a comma after the curly brace I indicated above.
