No response when downloading large folder to local storage

[guoyunhe]

Actual behaviour

Android says "Nextcloud no response. Wait or Stop?".

Expected behaviour

Nextcloud should download files quietly in background.

Steps to reproduce

1. Create a folder in server, upload a large amount of audio or videos. (I have 3GB *.flac music, average size 60MB)
2. In Android app, choose the folder to synchronize.
3. Leave the app and continue using the phone for other tasks.

Environment data

Android version: Android Pie, MIUI 11

Device model: Mi Max 3

Stock or customized system: Custom

Nextcloud app version: 3.8.0

Nextcloud server version: 16.0.5

I am getting the exact same issue with many smaller files, I have about 66000 files in one folder and it freezes and then crashes with the close or wait popup.

I often see this. The solution is to dismiss this and simply wait.

It feels like the whole app is single threaded and this bottlenecks.

The issue is rather that it is a synchronous foreground action which is limited by Android regarding its duration and if it hits a threshold Android will ask the users of they want to wait or terminate.

The correct way would be to do this asynchronously in the background but that implies a complete rewrite which is very time consuming.

I would like to point out that when it crashes it permanently disables synchronisation, so I am effectively not able to sync files to my phone because there is one larger file in my directory.
