UI blocked after wakeup from standby and task switch

[zamzon]

For about several months now after switch on device or working with other App, the UI doesn't react on any button or action for 10-15s (playing goes on).

I'm using GMMP on an S7 (android 8, 4GB) and an Galaxy Tab 2 (3GB) with about 150.000 m4a tracks in a folder structure genre/artist/album. Behavior basically the same on both devices.

Either there was a threshold for the number of songs, where some limitation shows up or it changed with a newer version of GMMP - but for sure this was not always this way (with maybe 100k tracks).

What could cause this blockage of UI? what can I test or change to speed up?

Thank you.

Thomas.

Try the 3.0 beta. 150k is certainly way above some of the android limits on cursors (database query results.. kinda). 3.0 uses paginated queries so only a small fraction of your collection is loaded at a given time
