Quickdroid

Developer's DescriptionBy Daniel HimmeleinSearch, find and launch apps, contacts, bookmarks, artists, albums, and songs on your Android device.Quickdroid for Android has a plugin interface which enables you to easily extend it by other search categories. Quickdroid does not run all the time. It only runs when you use it and also for a few seconds after un-/installing apps to sync the app index. For all other search categories Quickdroid uses the Content Providers that are already available on your phone. The quick launch symbol is only a PendingIntent. So this optional feature does not keep Quickdroid around all the time. However, Android tries to always keep around some of your most recently used apps (and their respective Linux processes) to speed up the startup times of these apps.
