"We found an issue where certain Android keyboards (like the S6 with
predictive text) wouldn't work ... Certain keyboards use a predictive text
mode that does not dispatch a traditional onKey events, which is troublesome
... but telling the OS to use a "visible password" keyboard helps deal with
this problem ... perhaps there's some other way (onKeyPreIme?) to do
"textediting" events, but for now, this should be a fast fix ...
I hear it affects the Galaxy Tab A 8.0", Galaxy S6, Asus ZenPhone 2, maybe
others"
They were not needed internally since the switch to the common EGL backend.
Thanks to the SDL mailing list for pointing out that the functions seem unused.
It was redundant because SDLActivity already inherits an empty method from the
base class SurfaceView (which does not implement it but inherits it from View).
Visibility of onDraw() in SDLActivity is now protected again instead of public.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
