Quickstart-android: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.net.NetworkInfo.isConnected()' on a null object reference com.google.firebase.iid.zzad.zzchr ()

[opus1269]

• Android device: Moto G (4), LG-US996
• Android OS version: 7.0
• Firebase/Play Services SDK version: 11.6.0

I have received this in Crash Reporting in production on the above two devices. In both cases the devices were in Connection State: Disconnected

Not sure if this is during an app update or on app launch. Since the devices are disconnected I would think it would not be during an update.

Crash Report details:

I've the same problem in my app, not related to a specific device or Android version.

Crashlytics reports 228 crashes on 134 users since last week, when I updated to Firebase/Play Services 11.6.0.

Yesterday I updated the libs to 11.6.2 but didn't solve the problem, my users are still experiencing the same problem.

One of the hundreds of crash report details:

Thank you both for the report. I looked into the source code of the iid module and I don't see any calls to isConnected() not guarded by a null check but I will follow up with the team anyway and see what I might be missing.

Thanks @samtstern!

On stackoverflow there are other developers experiencing the same issue in the last hours: 1 - 2

If you need more logs/informations don't hesitate to ask.

@opus1269 @mengoni thanks for reporting this! I can confirm that we identified the issue and have a fix that will be included in the next release of the Firebase / Play services SDKs. I can't promise an exact date, but should be before the end of the year if all goes well.

I am going to close this issue now as there's nothing more that can be done in the context of the quickstart-android repo.

@samtstern is it fixed on Firebse 11.8.0?

[samtstern]

@opus1269 @mengoni @amorenew @jackcsk this issue is fixed in 11.8.0

[rafid059]

Problem still persists on 11.8.0.

compile 'com.google.firebase:firebase-core:11.8.0'
compile 'com.google.firebase:firebase-messaging:11.8.0'
compile('com.crashlytics.sdk.android:crashlytics:2.7.1@aar') {
    transitive = true
}

Device states: 100% In background

[denisvasyanin]

Same here in 11.8.0, 98% in background

[samtstern]

@rafid059 @disav1 I am surprised to hear that you're still seeing this issue in 11.8.0. Could either of you provide some additional crash logs? Whatever you have would be helpful.
