I’ve tried several apps now to keep the Android Spotify Connect server running smooth. I’ve already written about Autostart and Stay!, a must for this system. Now I found another app which seems to extend the “uptime” alot. It’s called All-in-One Toolbox. It has a lot of functionality in it, but a great thing about it, is that it can do some tasks automatically via plugins. I have set it to clear the cache and remove junk files automatically at a specific time interval. I also have set a feature which disables the wifi at a time interval (at night).
Since I use this app, the MK808II seems to running smoother, and has a much longer uptime. Spotify Connect is now almost always available. So maybe it’s useful for you too.
