Android launch UI stream using AndroidAnnotations

I decided to deal with such technology as AndroidAnnotations .
In the declared functional there are two such annotations :
@Background - starts an external stream, this thing worked correctly.
@UIThread - starts a thread in the UI, this thing refuses to work.
I tried using the standard solution via runOnUiThread () instead of @UIThred, it worked perfectly.

Error when using @UIThread:

E/AndroidRuntime: FATAL EXCEPTION: pool-3-thread-1 Process: evilroach.com.test, PID: 27529 android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views. 

Classes in which I try to use annotations:
