Android App not working with Firebase plugin

I am using Firebase plugin in my APP,
While building APK it was giving error with multiDex, then I added multiDexEnabled true and build the APK
This APK is not working in device , it says App stopped working

@ChrisGriiffith I think Ionic Team need to clear out this about using Firebase in Ionic Apps.
Many of developers facing same issue many times.
Request you to please provide your suggestions and input.
