Backup process with "sync"

[MicKle3]

Hello @cgutman,

I want to backup some files via my developing application. So, I used "sync" connection and opened stream via "RECV". (I want to pull about 40 files in this stream).
But, sometimes adb pulled these files, sometimes no. When I debug this problem, read() function is not return anything. read() is always waiting.

How can I solve this problem?

(I hope, I can explain my problem.)
