Android Question failed lock verification and will run slower.

[aaronk]

Hi,

What does the following messages mean? Should I be worried about them or is this normal ?

I am using Firebase Notifications, and noticed in the IDE log (un-flited log) it logs the following:

** Activity (main) Resume **
*** Service (firebasemessaging) Create ***
** Service (firebasemessaging) Start **
Class com.google.firebase.iid.zzac failed lock verification and will run slower.
Firebase General
Class com.google.firebase.iid.zzm failed lock verification and will run slower.
Class com.google.android.gms.tasks.zzp failed lock verification and will run slower.
Class com.google.android.gms.tasks.zzn failed lock verification and will run slower.
Class com.google.android.gms.tasks.zzi failed lock verification and will run slower.
Class com.google.android.gms.tasks.zzg failed lock verification and will run slower.
Class com.google.firebase.iid.zzp failed lock verification and will run slower.
Class com.google.android.gms.tasks.zzj failed lock verification and will run slower.
topic sync succeeded
Sending crashes

I was running the above in debug mode.

I do notice a few logs in my Google Play Console and not sure if it's related or not..

You can ignore the failed lock verification. They are not related to the crash.

About the crash, what is the value of targetSdkVersion? Are you using B4A v8?

what is the value of targetSdkVersion?

<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="26"/>

Are you using B4A v8?

Yes.

There isn't enough information in these logs to say much other than that a service has failed to start. The issue might be in Service_Create of that service.

Worth adding Crashlytics if you see many such errors.
