Building to android fail- unable to convert classes into dex format.

Questions & Answers
1

Hello, I have problem with building to android. Since I am beginner, I have no idea what to do, because building to iOS worked. First I had error with android manifests, but I got this fixed.
I am using Google AdMob plugin from: GitHub - googleads/googleads-mobile-unity: Official Unity Plugin for the Google Mobile Ads SDK

Now I get this error: CommandInvokationFailure: Unable to convert classes into dex format. /Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/H‌​ome/bin/java -Xmx2048M -Dcom.android.sdkmanager.toolsdir=“/Users/admin/Library/Andr‌​oid/sdk/tools” -Dfile.encoding=UTF8 -jar “/Applications/Unity/PlaybackEngines/AndroidPlayer/Tools/sdk‌​tools.jar”

If somebody knows, how to get rid of it, I would be extremely thankful!
Full error looks like this:

CommandInvokationFailure: Failed to re-package resources.
