You may try using --multi-dex option.

Starting with Unity 5.5, you can use Gradle directly from unity.

This means, that after the initial setup for Gradle (it’s more strict than the previous “internal” build system), you can use ProGuard or multidex to overcome this issue.

Hello, I am facing this issue while I added the FCM plugin into my project. before this plugin I had various plugins already added to my project. Namely, chartboost, adcolony, unity-ads, everyplay, vuforia.
I am using the FCM plugin from : https://firebase.google.com/download/unity.
Before the current multi-dex issue, I was having issue with support-v4 which was present in the plugins multiple time which i removed manually.
If there are similar thread which have already solved this problem, then please post a link for that thread, it will be so much for a help.
I am workin with Unity-5.6.1f1 (Personal Edition).
I have attached a text file which contains the final error that I am stuck with.

Below I havet this is unity console, it might help you understand more :
"
FAILURE: Build failed with an exception.

  • What went wrong:
    Execution failed for task ‘:ChartboostSDK:processReleaseResources’.

com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process ‘command ‘E:\android-sdk\build-tools\25.0.3\aapt.exe’’ finished with non-zero exit value 1

  • Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

The Gradle build system is a lot more strict and sensitive for various kinds of errors. You can check out this link to see how to handle various Gradle errors.

Also, if this is an urgent matter, you can always contact me (via the link in my signature) to get (paid) assistance.

This issue means you have accidentally deleted the “google play services” files or libraries.
