problem with FCM notification on android

Hello guys, I have problem when making android notification app with FCM.

* What went wrong:
Execution failed for task ':app:transformClassesWithDexForDebug'.
> java.util.concurrent.ExecutionException: Multiple dex files define Lorg/hamcrest/Description;

as my research they said I have to put

android {
    defaultConfig {
        multiDexEnabled true

to my gradle app but I don’t know how to do it. could you please give me a clue ?

I don’t know of a way to enable multidex support currently, but please see this forum post about multidex for a potential solution to your problem.

Hi Uldis, thank you for your advice but I tried it before I made this topic and it didn’t help (I tried with version 9.2.0 10.2.1 11.6.0) same error for all versions, I just want to test FCM Notification with native JAVA code cause your FCM Support on FUSE is not quite suit our purpose. I uploaded my project here please take a look, cause if you don’t know then no one know ^^.

Thank you.
