Android: Problems with firebase-auth and appcompat

Question

I'm integrating firebase to my app, but when i go to implement firebase-auth:9.0.0 i have this error:

java.lang.IncompatibleClassChangeError: Class com.google.firebase.auth.FirebaseAuth implements non-interface class com.google.android.gms.internal.zzaja (declaration of 'com.google.firebase.auth.FirebaseAuth' appears in /data/data/com.viridesoft.kiseichuu/files/instant-run/dex/slice-com.google.firebase-firebase-auth-9.0.0_9a8a00b0dd4fa0b0760eb2c17842365e25734a0b-classes.dex)

I read that this error is caused by the incompatibility between firebase-auth:9.0.0 and appcompat-v7:24.1.1.

I don't know how to solve this problem.

Edit: the problem was solved, my problem was the version of the library, i have all 9.4 but auth was 9.0

Post your module build.gradle file. Are all the Firebase libraries the same version? See here: http://stackoverflow.com/a/38438897/4815718 — Bob Snyder, Sep 15 '16 at 16:46
Txs qbix, i read and copy the guide for implement firebase but google put me 9.0 in auth and 9.4 in the others. — Adrián Pastoriza, Sep 15 '16 at 17:03
Please post an update if consistent versions of the libraries fixes the problem. — Bob Snyder, Sep 15 '16 at 17:19
I can confirm this is an issue with mismatched library versions. Check *all* of your google play services libraries, plugins, and classpaths. — Chad Bingham, Sep 15 '16 at 17:35
Please remove `solved` from your title, and post the solution you found as a proper answer. — Jongware, Sep 16 '16 at 20:38
