Use a Codename One app for a tv box with tv remote control

由 大憨熊 提交于 2019-12-08 00:57:47
问题 I tried to install a Codename One app on a tv box that runs Android 7. It works, except the fact that I cannot use the tv remote control to switch from a Button to another (I need to enable the mouse pointer simulation to tap the Buttons, that is not user friendly).
