What I'm looking for is a way to switch the keyboards automatically based on the app being used. The only reason I want this sort of automation is because I'm using Google's ASE app, and the interpreter panel / interface doesn't allow switching keyboards. It does not pop up with the menu to do so after tap-holding.
Right now I have to switch to another app, switch keyboards, switch back to ASE, re-open the interpreter, and then start typing. In ASE I would prefer to use Android's native keyboard, while I use Swype for everything else.
