Fail to list folder with 600+ files on SAF R/W mode on external storage. [workaround found] #178

System Huawei P9lite (Android 7) + 128GB Samsung Evo+ PC client Filezilla (300s tiemout)

when trying to list a folder with 640 files it fails, I found that with 600s timeout it works but is painfully slow. Possible solution is to send the client some message every 150sec for example a code 211 or 214 indicating slow operation preventing timeout with the most common default value of 300seg.

PD. Why don't use 2 methods to access the media, SAF slow for writing and another faster for listing and if possibly also reading.

Well, that SAF is slow is known. That is the reason why I created read-only SAF. The root cause is Googles approach to prevent SD Card from beeing accessible by Filesystem API.

Sending Codes 211/214 would be interesting but in this case hard to do as this app does currently not implement protocols in its own but uses libraries from Apache Mina.

Mixing SAF APIs for reading and writing would be interesting, too. But that would be a Major Code Change and Takes time.

By the way: contibutions are Welcome ;)
