AnySoftKeyboard

Supports swipe/glide typing - YES. 

User comment:

AnySoftKeyboard needs the languages to be installed as “plugins” via apks, this means after uninstalling the app, you need to uninstall a bunch of “apps” which are just languages/keyboard layouts. The languages are all named wrongly in F-Droid and there seems to be no Bulgarian language. The actual layout of the keys (size & spacing) causes me to mistype more often than on any other keyboard.

FlorisBoard

Supports swipe/glide typing - YES (English only). 

User comment:

Florisboard is pretty neat for alpha, but it currently mixes the suggestion dictionaries for all installed languages and it’s prediction is generally bad.
