v.0.14 is published.
Before it the uploading and deleting manual functions worked in the queue, but the downloading - only for a single file.
Here in v.0.14. i have debugged well all functions, and the interface (Activity) now helps to check all actions: taps make a single file operations, and long-tap - makes queue operations - several files are uploaded, downloaded or deleted. The files list - it's content of the local_folder where FTP files are synchronized - each second it's visible what downloaded or deleted, or updated.
Also added one more error handling and errors counter.

Now it needs to test well, especially with big files and unstable Internet connection.
