DefVideoAds (plugin for Unity ADS). Video ADS native extension

I have two rewarded ad ids set up in my game. After they have both shown, no new ads load. There doesn’t appear to be a way to preload rewarded ads.

How does the loading of rewarded ads work? Is there a way to force a load?

I have only one in my game, and it works this way:

  1. I init ADS
  2. I check if rewarded ADS is available
  3. I show rewarded button
  4. User tap to the button - I show ADS
  5. back to 2

ADS can be unavailable because of different reasons (no ads in the current region or limitations you setup in ads dashboard and so on)

Ah, that might explain why it works in one game with one rewarded ad and not in a different game with two rewarded ads.

I’ll do some more digging.

Edit: It was a logic error in my code, multiple rewarded ads now work great. Sorry for waving red herrings around publicly. :blowfish:

DefVideoADS 3.4.8

Now DefVideoADS is compatible with iOS 14. This version of the extension requires Defold 1.2.174 or higher.

UPDATE: UnityADS SDK updated to v3.4.8

Nice to see this extension keep getting love! Unfortunately I’m unable to use 1.2.174 because of this bug.

Is there a way to use the iOS 14 compatible version of the extension with 1.2.172?

Edit: I upgraded to Defold 1.2.174 and tried using DefVideoAds v3.4.8. As soon as unityads.initialize() is called, there is a hard crash on iOS (13.5.1). Reverting back to v3.4.2 solved the problem.

Have there been any changes to the API between v3.4.2 and v3.4.8?

No, there is no difference in API.

I have tested the newest version on iPhone 5c with iOS 10.3.3 it works fine.
If you provide logs it help me to find the reason for the crash. Unfortunately, I don’t have a device with iOS 13.5.1.

Yes, use beta extender server (https://build-stage.defold.com) even if you use 1.2.172 (the extender has one critical fix for v3.4.8)

I’m back! :smiley:

When building DefVideoAds v3.4.8 with the latest Defold v1.2.164 build using http://build-stage.defold.com/ I get this crash on Android:

The ad implementation in the game hasn’t changed. Any idea what might cause this? I’m not certain it’s to do with DefVideoAds, but the “DefUnityCallback” appears to suggest it is?

Could you check please if default example project works for you (download project from rep. of DefVideoADS and build).
(I’m re-checking using the latest 1.2.174)

UPD: Also, try this, pls:

  1. Remove “build” folder from your project folder
  2. Build and test game again

UPD2:
I watched 14 x 4 = 56 videos + opened 2 x 4 = 8 banners, it works for me.

Sooooo, that means I can’t reproduce this issue without exact steps, and minimal repo case. Also it would be nice to know more info about devices you tested on (OS, Model).

It might be that it doesn’t play nice with one of the (many, many) other extensions in the project? Will try a clean build this morning.

Update 1: A minimal Lua implementation (no game, only DefVideoAds) using a bundled .apk with all the extensions the game use also crashes.

Update 2: A minimal Lua implementation using a bundled .apk only with DefVideoAds extensions doesn’t crash.

Where should I start? :sweat_smile:

Could you provide your project with all the extensions you use, please? I’ll take a look today evening.

UPD:
The simplest way is to cut off all the extensions you use and check. Then if you don’t have crash, return just a half of cut extensions and so on.

Thanks for your help @AGulev! I’m going in. I’ll ignore the pure Lua extensions for now, to make the task less daunting. Wish me luck! :slight_smile:

Update 1: I was lucky in my first batch. One (or more!) of these is the culprit: Facebook, GameAnalytics, Firebase or Google Play.

Update 2: It seems to have something to do with Firebase; keeping all extensions except Firebase causes no crash. However, an .apk with only Firebase and DefVideoAds also doesn’t crash. This stumped me a bit. Any suggestions?

When it does crash, it consistently happens as the DefVideoAds callback is fired, so a few seconds after the unityads.initialize() call.

Update 3: A new iOS+Android build of the full game, with the Firebase extension removed, works and doesn’t crash. How can we allow both DefVideoAds and Firebase to coexist?

I’ll take a look today evening and try to figure out.

UPD: If you add firebase into DefVideoADS example project, can you reproduce this crash? Could you try to create minimal repo-case for me based on DefVideoADS example, please? @totebo

Very unlikely, because an entirely empty project with only DefVideoAds and Firebase doesn’t crash. I guess this means there is (at least) another extension that causes an issue, but finding which one would be very time consuming.

Since I can consistently replicate the crash, is there a way I could produce a more detailed error that could help narrow it down? I could send a debug .apk if that helps?

I think it depends on what you call before show ADS and in ADS callback. Try to do the same In empty example.
One more option is to share your project with me (in PM of course)

Are you sure it’s a broken Lua stack? According to the crash shared by Totebo it seems like it is this line crashing:

The key_1 and value_1 values are not checked. Are we sure they are ok? Perhaps you could dmLogInfo() print them one by one before they are used and put that on a branch for Totebo to try?

Also, @totebo: How are you invoking any of the DefUnityAds functions? Are they called from within some callback or directly from the Defold lifecycle functions?

I use a lua module:

local M = {}

local function unity_ads_callback( self, msg_type, message )

	pprint( "unity_ads_callback()", self, msg_type, message )

end

function M.initialize()

	pprint( "ads.initialize()" )
	
	local test_mode = false
	local game_id
	local sys_info = sys.get_sys_info()
	if sys_info.system_name == "Android" then
		game_id = "4350934"
	elseif sys_info.system_name == "iPhone OS" then
		game_id = "2309234"
	end

	if unityads then
		
		local unityads_is_supported = unityads.isSupported()

		print( "unityads.isSupported()", unityads_is_supported )
		
		if unityads_is_supported then
			if unityads.isInitialized() then
				print("unityads.setCallback()", unity_ads_callback )
				unityads.setCallback(unity_ads_callback)
			else
				print("unityads.initialize()", game_id, unity_ads_callback, test_mode )
				unityads.initialize( game_id, unity_ads_callback, test_mode )
			end
		else
			--print("Unity Ads are not supported on this device")
		end

	end

end

return M

Called like this:

local ads = require "main.ads"

function init(self)
	ads.initialize()
end

See the empty example above (that’s all the code in the project).

Ok, so there really shouldn’t be any problem with other extensions when setting up the callback. The DefUnityAds extension callback uses polling and will run together with other extensions which have an update method defined. But I don’t really see how they would interfere, especially since you’re restoring the Lua state from the callback. Printing values inside that callback function in the extension may help shed some light on the problem.

Please share code how you call “show” and what is your PlacementID(s)
