I got this error in 3 places:

1) logger = LoggerFactory.getLogger(name);
2) mMessagesJobManager = new JobManager(this, configuration);
3) Fabric.with(this, new Crashlytics());

I didn't find any info about these methods in documentation. I found only one solution - use AsyncTask, but should I fix it? If yes, why documentation doesn't contain any info about it? Best regards.
