Make sure to call back reportFinish() on the desired Handler.
Before exposing #reportFinish() as a public API, we have to fix an
existing bug that my previous CL [1] for Bug
26945674 forgot to take care.
Currently BaseInputConnection#reportFinish() is always called by using
the root view's Handler. We should move the logic to call
BaseInputConnection#reportFinishInputConnection() from ViewRootImpl to
IInputConnectionWrapper to make sure that the method in question can
always be called on the desired Handler.
To make things simple, instead of explicitly calling #reportFinish()
from IMM, this CL let ControlledInputConnectionWrapper#diactivate()
internally call #reportFinish() as needed. This makes it easier to make
sure that #reportFinish() is called after all the queued method calls
are handled.
