Unity ads - Build error

minh23520000 · February 21, 2018, 3:20pm

Hi, I just integrate Unity ads and try to export my game to android platform and got this error: (My game run and export completely normal before adding unity ads).
“com.android.build.api.transform. TransformException: com.android.ide.common.process. ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexException: Multiple dex files define Lcom/unity3d/ads/BuildConfig; See the Console for detail”.

Here’s the detailed problem:
CommandInvokationFailure: Gradle build failed.
C:\Program Files\Java\jdk1.8.0_161\bin\java.exe -classpath “C:\Program Files\Unity 2018.1.0b4\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\gradle\lib\gradle-launcher-4.0.1.jar” org.gradle.launcher.GradleMain “-Dorg.gradle.jvmargs=-Xmx2048m” “assembleRelease”

stderr[

What went wrong:

Does anyone know how to fix this problem? I’m using Unity 2018.1.0b4 on Window 10 - 64 bit
Thanks

Anyone? Thanks =))

gamerkendall · May 3, 2018, 10:15am

I hav faced this issue too. Have you resolved it ?

AndresSepulveda · May 6, 2018, 4:18am

Same Here…

Idealisers · May 9, 2018, 6:29pm

I also have this issue, running unity 2018.1.0f2. Did anyone solve it?

EDIT :
I solved it by removing an clashing lib from the plugins directory.

Unity ads? Don’t you mean AdMob (Google ads) ?
Anyway, same issue here. For me I guess it happened because I moved the GoogleMobileAds folder form the root (Assets) folder to Plugins and messed around with other folders there too because I didn’t like the structure.
In the end I couldn’t recover from the error and I just deleted the whole AdMob plugin and imported it again, works like a charm!

To fix this, I disabled the built-in unity ads extension under the unity ads service advanced settings, but left the unity ads enabled. Download and import monetization 3.0 or whatever the latest unity ads implementation is from asset store. Now it builds successfully, but the test ad only shows in the editor. Perhaps this will stop when I disable test mode?

rupeshyadav · November 14, 2018, 12:20am

Disable this and it will work perfectly… Do note the warning message shown by unity, so if you have downloaded asset package Unity Monetization 3.0 directly from the asset store than it will work fine.

I am yet to try if my ads are showing up in production.

AAAAAAAAAE · November 20, 2018, 8:41am

This worked for me

Close Unity Editor
Backup your project
Remove any folder or meta file called UnityAds from your project’s Assets/Libs folder
Remove any folder or meta file called UnityAds from your project’s Assets/Plugins/Android folder
Start Unity
Build your project for Android

If this doesn’t work, try doing an Assets > Reimport All, then building again. Hopefully, future version of Unity will solve this problem automatically. Good luck out there!

bahaeddine666 · June 7, 2019, 4:27pm

This actually works for me, if you think about it, it’s so logical, why would you enable Build in ads extension while you are actually using unity monetization !!

sarvagna-shukla · September 21, 2019, 10:26pm

This worked for me too !!!

thebrad52 · October 4, 2019, 7:33am

It actually works! @bahaeddine666 will the ads work you put the game out on the play store?

hjakar6 · October 9, 2019, 7:25pm

it worked for me

thebrad52 · October 29, 2019, 4:33pm

They worked for me too! Wish i had a million downloads though

check out my game

Thank you so much

If still anyone out there couldn’t fix the issue, here is my situation:

I implemented Google Admob to my game years ago. A few days ago I deleted all the code about Admob and implemented Unity Ads and after that I couldn’t get any build.

I fixed it by just deleting plugins folder.

.!! Please back up your game if you are thinking about doing the same as me !!
