I faced with the next problem:

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.

That is because none of them are part of Android. Presumably, they are from libraries that you added to your app (slf4j, Fabric, and I'm guessing perhaps Firebase).

Well, your app is crashing. If you want to ship this app, you need to do something to stop crashing.
In your code, you configured StrictMode to apply penaltyDeath() for disk reads. Hence, your choices are:
Move this disk I/O off the main application thread, which is the best solution in general, though it may prove impractical (given that you do not control the implementation of the libraries)
Stop configuring StrictMode to apply penaltyDeath() for disk reads.
If yes, why documentation doesn't contain any info about it?
There is documentation on StrictMode, if that is what you mean. Beyond that, I imagine that Google expects professional app developers to read books, take courses, or find other ways to learn about Android app development beyond what is covered directly in the documentation.
