[Unity 5.2] The imported type `UnityEngine.Advertisements.ShowResult' is defined multiple times

Hello,

Today I have upgraded my project to Unity 5.2.

I have issues with UnityAds as it gives me errors:

error CS0433: The imported type `UnityEngine.Advertisements.Advertisement' is defined multiple times
error CS0433: The imported type `UnityEngine.Advertisements.ShowResult' is defined multiple times
error CS0433: The imported type `UnityEngine.Advertisements.ShowOptions' is defined multiple times

Any ideas how to fix it?

Thanks in advance!

 

Same problem here, and this is after I have imported Unity Ads from the asset store into a completely new project.

 

I solved the problem! UnityAds is implemented into Unity Editor starting 5.2 (just like other Unity plugins).

You must remove UnityAds asset from the project.

 

how are we supposed to work now in Unity ads? I can't find any type of documentation for 5.2

 

As elmar1028 pointed out, the ads system is now built into Unity, so there's no need to download it from the asset store. Furthermore once you've enabled ads in the services Window and linked your app to it, you don't even need to init() the system with your app ID etc. as this happens automatically.

The two code examples they provide in the services window will work as they are, however you can still refer to the live training video for further information, as pretty much everything apart from the installation and initialisation bits is still relevant.

One thing that might cause confusion, is that you need to switch to Android or IOS build type, or you'll get errors when you run the program. This caused me some head scratching for a while

 

I don't know if its only me, but if I try to enable the Unity ads service in the services window, it still says off. Any idea why this can be?

 

Maybe this helps someone. If you removed all the files, remember to restart Unity. This way, the services panel will work correctly. Thanks for your help Munchy2007

 

Good you solved it yourself. We do have some documentation for enabling Ads in 5.2 using the connect window at http://docs.unity3d.com/Manual/UnityAdsHowTo.html.

However, you should also be able to continue using the Asset Store Ads package in 5.2, however I've seen that it can require a reimport of assets in Unity to have it detect that Asset Store package should be used.

Hi,

I removed all the UnityAds folder (Standard Assets, Standard Assets Editor, iOS one and Android one), restarted Unity, but the "type or namespace ShowResult" still couldn't be found (as every UnityEngine.Advertisments class). Am i forgot something ?

Thanks

 

There is a free plugin – Package Uninstaller. I used it to remove UnityAds plugin and it worked.

If it still doesn't work then restart Unity

 

I found it : allowPrecache and a parameter in ShowResult function was removed in the last SDK, cause my compiler, well, not compile, and showing a bad error instead.

Solved !

Now my Unity 5.2 is instant crashing when I hit play (works fine in 5.1.3) but this is another subject...

 

Hi all.

I had the same problem and fortunately I could solve with the elmar1028 advice, uninstalling the unity ads plugin with Package Installer.
But now, with the new UnityAds implemented into Unity Editor, the ads loads slower than before.
Does anyone else have this problem?
Can it be because now we can't use allowPrecache?

Thank you.

 

As far as I know allowPrecache doesn't work at all.
Assigning a value doesn't change anything as it always returns true.
Found here

 

This is what i did:

- Remove unity ads plugin (Plugins and standard asset folders).
- Linked my game with ads through unity service window.
- Remove unity ads initialization from my code "Advertisement.Initialize (GameID)".

 

Hey, thanks The Ballo for mentioning removing the initialization code. What a monkey I am, scratched my head because I was getting an Advertisement.Initialize error! It doesn't need to be there anymore, removed it, fixed! Cheers.

 

Is it still possible to initialize UnityAds at Runtime? I need to provide different IDs depending on the type of version I create from the project. At Boot I check some environment settings and decide if I want to initialize version A or Version B of the project. This worked fine with the Plugin-Solution. How is the situation on 5.2?

-act

 

I also had this problem, and what I wanted was to initialize Unity Ads at runtime instead of using the new method. I have solved it just right now by enabling the ads from the services window, and then disabling it, now it works fine.

 

This seems like a mess to me.

It appears you can control initialization manually and still use the integrated 5.2 Ads code if you edit `ProjectSettings/UnityAdsSetttings.asset` manually and set `m_InitializeOnStartup: 0` There is no inspector setting for this field. This works fine on Android using the same initialization code used with the asset store Ads plugin.

No amount of fiddling will allow us to run iOS builds with ads on 5.2 without EXC_BAD_ACCESS errors. The only way we can get an iOS build running on 5.2 is to disable Unity Ads. We had no problem with iOS on 5.1.

 

i just copy and past :

var options = newShowOptions { resultCallback = HandleShowResult};
Advertisement.Show("rewardedVideo", options);

and i get

A method or delegate `canvasMain.HandleShowResultContinue(UnityEngine.Advertisements.ShowResult)' parameters do not match delegate `System.Action<UnityEngine.Advertisements.ShowResult>(UnityEngine.Advertisements.ShowResult)' parameters

 

I just checked building on iOS after changing that parameter in UnityAdsSetttings.asset file and that worked for me as I can see from the Debug-Output. Unity Ads requests the correct data for the appropriate GameID I initialize at runtime. That m_InitializeOnStartup variable should be public to avoid hacking the .asset-file.

It is not showing the ad though for some other Unity 5.2 related change or bug I assume:

Attempt to present <UnityAdsMainViewController: 0x13d7e9520> on <UnityLandscapeLeftOnlyViewController: 0x13d56bbe0> whose view is not in the window hierarchy!

Anyways, the basic initialization at runtime works with your hint. Thank you!

How can I change UnityAdsSettings.asset manually ?

I develop app for one of my client and I have his unity ad ids.

So there is only way to use UnityAds is manual initialization.

 

@trueDenton - open the file in your editor, it's just plain text

 

It was a first thing i did. But it is not.

 

It looks like you may need to change Edit/Project Settings/Editor Asset Serialization to "Force Text"

 

This has broken my existing project. New services require me to login. How to disable 5.2 native UnityAds for existing projects which already have game id and unity ads integrated.

Also for service login, What credential am I supposed to use? My developer credential or team publisher credentials used with unity ads. Does that mean every developer need to have team account access?

 

new service does not even let me link to an existing game. it ask me for one project id, but i've two different games with unity ads for android and ios..

 

Exact same issue, but it happened to me when I updated to 5.2.1 PATCH 4
Dont wish to use the editor integration as the project is not fresh one but old one and lot stuff have been manually coded.
Cannot just expect things to work automatically with this editor integration.

 

Editor integration had to be a bit smarter. Detect if you have already a plugin installed, then simply turn itself off.

 

You need to delete all the UnityAds SDK stuff from your project.

I wouldnt feel comfortable with Unity Detecting I've updated then deleting a bunch of stuff.

 

OKAY, then what? I get lot of red errors - this is missing/that is missing/you cannot do that!

Knowing Unity buggy state as always, the issue was fixed for me when I removed the UnityAdsSDK folder, but then I re-imported UnityAds from the asset store. I'm working in offline mode and upgrading a old project, I appreciate all maybe working for fresh projects but its not always clear for existing projects.

Apologies for the frustration

 

Im going to assume you are using Unity 5.2.x...

Delete all the SDK stuff, you dont need it at all. Not one file. Nada!

Goto the Services Window/Tab. Enable Unity Ads, connect the game (make sure the id's are there). I forget if I had to set this up in the UnityAds Dashboard first (its likely)

Include Unity.Advertisements (think that's the namespace)

Call Advertisement.Show(null) - or whatever the function is. You dont need to Initialise. The only other code you might want to run is Advertistment.IsReady(null) before calling show.

Thats it. If you are using a version of Unity that doesnt include UnityAds (ie prior 5.2) You're on your own sorry.

 

Received this error with Unity Ads today in one of my projects. It was an easy fix in my case. Turned ON Unity Ads in the services window, then turned it back OFF.

I prefer the Asset Store Ads package because that way preprocessor directives can be used to automatically switch to test ads when creating a development build. Also saves me from accidentally publishing a release version with test ads enabled due to forgetting to toggle that setting.

 

this is weird I when I turn off the unity ads the error will disappear but when I enable it again the error comesout

 

I ended up having the error come back and had to take a couple extra steps. Unity is adding a reference to UnityEngine.Advertisements in the project file upon open even if UnityAds is turned off in the services window. Here is what I did to resolve it thanks to information from posts above...

1. Edit > Project Settings > Editor
2. Change Asset Serialization Mode to Force Text
   
   If it’s set to Mixed, I recommend switching to Force Binary first to avoid issues with converting to Text.​
3. Go to the Services window
4. Turn UnityAds On then Off
5. Close Unity
6. Edit the following file in Notepad or another text editor:
   
   <ProjectDirectory>/ProjectSettings/UnityAdsSettings.asset​
7. Change initialize on startup to zero:
   
   m_InitializeOnStartup: 0​
8. Save

That seems to have taken care of it. The error hasn't come back again upon reopening the project or building it. Still using the UnityAds imported package.

Edit for Clarification: These steps are for if you need to use the UnityAds package from the Asset Store. Otherwise, the package files should be removed in favor of using the integrated services version of UnityAds.

 

amazing will check on this when i got back home from work, thank you so much sir @Vurawid

 

I found a solution that worked for me for the following errors
error CS0433: The imported type `UnityEngine.Advertisements.Advertisement' is defined multiple times
error CS0433: The imported type `UnityEngine.Advertisements.ShowResult' is defined multiple times
error CS0433: The imported type `UnityEngine.Advertisements.ShowOptions' is defined multiple times
all i did i went into the services window in unity and switched Unityads off and the errors went away and the test ad still works

 

This is weird i stil have the same error,i mean it will go out then it will pop up again darn

 

well seems like i was not able to take out the Unity ads plugin entirely thats why I still ahve the error

 

Hi Folks,

The error "UnityEngine.Advertisements.method' is defined multiple times" will show up when your project includes both the old Asset package as well as the Ads service.

The solution is to remove the Unity Ads asset package entirely; Once the Asset Package files are removed, the integrated ads service should work properly.

 

thanks bro

 

I had both a Reference and a Plugin. I removed the Reference and it worked. Thanks!

 

Hello, this update broked Space Ads demo, that i implemented a long ago in my project.
Now, i need to debug a lot. Just to let someone know about my entire day frustration.

 

@DBar, sorry to hear about that. This particular one is hard to fix in Unity, but we could improve the documentation. What steps did you take when you experienced this issue?

-Rasmus

 

I get this error every once in a while, but only when reopening Unity after a crash.
I found an easy way to solve it. Just open any script, add a white space and save. After Unity recompiles the project, the error goes away.

 

I'm stuck here and it seems to be not my fault.

I recently upgraded my project from Unity 4.7 to 5.3 and so I removed the UnityAds plugin from my project to integrate it again from the Services window.

The problem is, my Services/Ads windows says:
"Unfortunately, your project cannot use the new UnityAds Dashboard yet."

The game is still not showing up in the UnityAds Dashboard, so it seems like I'll have to stick to the old way, but how can I use the old plugin in the new 5.3?

 

Thank you!

 

just do simple Step Go to services then unity ads after click to advance settings and uncheck to bulitten service after unlink your project and do script for ads

 

When I added Unity Ads 2.0 from the Asset Store in Unity 5.4, I had to turn off Unity Ads in the Services window to avoid the multiple definition error. With Unity 5.5, the error is back, even though Unity Ads is still turned off in Services. Do I need to remove the Asset Store package and enable Unity Ads in Services again?

 

Hey Developers I got the solution in Unity5.5 , After all cleanup and import of UnityAds2.0 go to Service--> Ads-->Advance and uncheck Enable builtin Ads extension after that all multiple definition errors cleared.
This perfectly work for me fully tested.

 

Does anyone know if I get this working on a game built for Android, would it still work if I copied the folder onto my Mac and made a build for iOS?

I know I can do with with standard games, that don't have adverts, but I haven't tried it with ads yet, and was curious to see if anyone else had.
