@iboylmz try updating your dependency to compile 'com.google.firebase:firebase-messaging:9.0.2', I believe this bug was fixed in the patches between 9.0.0 and 9.0.2.

samtstern · 2016-06-07T23:26:54Z

@iboylmz closing this issue, please comment if the fix above does not work for you.

thomaskanzig · 2016-08-06T16:28:18Z

Hi guys, I did the same problem and after for very searches I find the solution:

Update the dependencies of firebase in the build.gradle with 9.0.2 version
compile 'com.google.firebase:firebase-core:9.0.2'
compile 'com.google.firebase:firebase-messaging:9.0.2'

This Resolved for me.

elsennov · 2016-09-02T07:41:01Z

I got this error on 9.4.0 , same error. Could anybody help? Thanks

GiorgioNatili · 2016-09-03T19:08:47Z

@elsennov I solved it by adding the following dependencies to the app gradle file

    compile 'com.google.firebase:firebase-database:9.4.0'
    compile 'com.google.firebase:firebase-core:9.4.0'
    compile 'com.google.firebase:firebase-auth:9.4.0'
    compile 'com.google.firebase:firebase-config:9.4.0'

elsennov · 2016-09-03T19:15:41Z

Hi @GiorgioNatili , thanks! Last day i just added firebase-core , then the error was gone.

JemarJones · 2016-09-10T14:59:42Z

I have all of my dependencies set at version 9.4.0, but am still experiencing this exact same issue. Any help?

doppie · 2016-09-12T14:18:35Z

@JemarJones In my case I forgot to add an empty constructor to the custom object I wanted to store in the FirebaseDatabase.

JemarJones · 2016-09-13T18:17:36Z

It turns out that i have a separate unrelated issue that i resulting in gradle to fallback to 9.0.0, which results in this issue. So in any case i'm sure 9.4.0 is actually working fine.

(all of them)

The I added these rules to dismiss them:

-dontwarn com.google.firebase.**
-dontwarn com.google.android.gms.crash.internal.service.**

My release build succeed, but when I launched my app I got similar exceptions like in this issue:

Could you please suggest me proper the proguard rules when using firebase crash?

Thank you.

@alashow what version of the client library are you using? As far as I am aware there are no specific proguard rules needed to use Firebase Crash but I could be missing something.

Hi everyone!
I need a help with my Firebase Remote Config that shows this error:

java.lang.IncompatibleClassChangeError: com.google.android.gms.internal.zzade$zzc$1

att this code: mFBConfig.fetch(3600)

mFBConfig.fetch(3600).addOnCompleteListener(this, new OnCompleteListener() {
@OverRide
public void onComplete(@nonnull Task task) {
if (task.isSuccessful()) {
Log.i(TAG, "Promo check successful");

                // If the fetch was successful, then "activate" the
                // values that were retrieved from the server
                mFBConfig.activateFetched();
            }
            else {
                Log.e(TAG, "Promo check failed");
            }

            showPromoButton();
        }
    });

Did someone know how to solv this problem???

Tanks
Paulo
