[MultiDex error] when installed firebase and appodeal

Hi
I add Appodeal plugin in my project and everything is fine, installed from here
https://www.npmjs.com/package/com.appodeal.plugin
because the link from ionicframwork doesn’t work for me

ok, when im installed firebase :

getting this error

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':transformClassesWithDexForDebug'.
> 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/google/android/gms/internal/zzee;

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

and I saw when installing one of them on second plugin (that already exist ) i get error message either firebase or appodeal

    compile "com.google.firebase:firebase-crash:+"
    compile "com.google.firebase:firebase-config:+"

i have :
Android Studio 2.3
updated sdk
delete and add platform
still not working

i think that appodel compile:

"com.google.android.gms:play-services-ads:9+"

has a conflict with firebase compiles:

  compile "com.google.gms:google-services:+"
    compile "com.google.firebase:firebase-core:+"
    compile "com.google.firebase:firebase-messaging:+"
    compile "com.google.firebase:firebase-crash:+"
    compile "com.google.firebase:firebase-config:+"

any solution plz???
