----------------------------------------------------------------
I am also experiencing problems while downloading multiple files via
FileTransfer (0.4.8) on an IPad2. I am using cordova 4.1.2, and File (1.3.2).
Memory consumption rises continuously, eventually leading to a memory warning,
and further to the app crashing.
[EDIT] I've just tested the FileTransfer again with 1000 dummy (txt) files à
200KB.
While processing file list:
- CPU: 120-130%
- Memory: 60MB rising up to 89MB
- Network: 200KB/s
There is no crash, and Memory stays about the same til the end. However, after
all files were downloaded, I would like the Memory to decrease again? Memory
stays at 89MB afterwards.
Is there some way of freeing the Memory consumed during FileTransfer?
I'll continue testing ...
