Speed improvements

[J05HI]

Some stuff could be improved:

• Currently each cover and music track is loaded separately with a superuser command which is really slow.
  We should copy all covers and encrypted mp3s to a normal accessible location (if they aren't already)
  • Cover loading
  • Music loading

We should copy all covers and encrypted mp3s

Wow, NO. When would you do that? During app startup? That would take forever, ignoring the fact, that this will use a shitload of additional space. Maybe covers, no way we'll copy mp3s though.

No, sorry for the bad description of the issue. I won't copy the mp3s. Only the covers (this takes a part of a second) and doesn't take that much space.

We only need to copy them if they aren't on the SD card, if they are already (in "SDCARD/Android/data...") we can access them with a normal file access.

Loading the covers on scroll will nearly instantly then.

That seems more reasonable, thanks for the better description. Should we maybe have thumbnails for most covers in memory already? Not large ones, just 128² or something like that.

Maby if it doesn't take too much memory.
