Android: NullPointerException on NetworkInfo.isConnected() with Firebase

Sometimes, on different mobiles (Android 7) there is this crash:

Fatal Exception: java.lang.RuntimeException: Error receiving broadcast Intent { act=android.net.conn.CONNECTIVITY_CHANGE flg=0x4000010 (has extras) } in com.google.firebase.iid.zzae@3c68978

Have you seen this error before? I don't know how to correct this bug...

Thank you very much guys!

The issue has been fixed in 11.8.0 . Please update your Firebase SDK version. Refer https://firebase.google.com/support/release-notes/android#20171218

final boolean zzchr() {
    ConnectivityManager var1;
    return (var1 = (ConnectivityManager)this.getContext().getSystemService("connectivity")) != null && var1.getActiveNetworkInfo() != null && var1.getActiveNetworkInfo().isConnected();
}

This is the code for zzchr. There is already a null check added for getActiveNetworkInfo but you are still getting NPE.

You can check on other possibilities of NPE here. Hope it helps.
