event.data

Overview

A JSON-formatted string which contains the following fields:

• adUnitId — The AdMob ad unit ID that generated the event.
• rewardItem — The reward item name as defined in the AdMob dashboard. This is only available when event.phase is "reward".
• rewardAmount — The reward item amount as defined in the AdMob dashboard. This is only available when event.phase is "reward".
• adValue — The estimated revenue value for the ad impression in standard currency units (e.g. "0.005" means $0.005). This is a string value, consistent across iOS and Android. This is only available when event.phase is "revenue".
• currencyCode — The ISO 4217 currency code for the revenue value (e.g. "USD"). This is only available when event.phase is "revenue".
• precision — The precision type of the reported revenue value. Possible values are 0 (unknown), 1 (estimated), 2 (publisher provided), and 3 (precise). This is only available when event.phase is "revenue". See Precision Types below for details.
• errorCode — The error code for the event that failed. This is only available when event.phase is "failed".
• errorMsg — An error message with the reason for the failure. This is only available when event.phase is "failed".

Precision Types

The precision field indicates the accuracy of the reported adValue:

Example

local json = require("json")

local function adListener( event )

    if ( event.phase == "revenue" ) then
        local data = json.decode( event.data )

        -- Revenue data
        print( data.adUnitId )       -- "ca-app-pub-XXXXXXXXXXXXXXXX/YYYYYYYYYY"
        print( data.adValue )        -- "0.005"
        print( data.currencyCode )   -- "USD"
        print( data.precision )      -- 1

    elseif ( event.phase == "reward" ) then
        local data = json.decode( event.data )

        -- Reward data
        print( data.rewardItem )     -- "coins"
        print( data.rewardAmount )   -- 100

    elseif ( event.phase == "failed" ) then
        local data = json.decode( event.data )

        -- Error data
        print( data.errorCode )      -- e.g. 3
        print( data.errorMsg )       -- e.g. "No fill"
    end
