i making game work on android phones , tablets. using full-screen mode render.
in game, can press button go back.
on phone, button allways available. on tablet, disapears during full screen mode.
can force on-screen buttons remain without compiling lower sdk version?
try
getwindow().getdecorview().setsystemuivisibility(view.system_ui_flag_visible); from official doc
the system_ui_flag_low_profile flag replaces status_bar_hidden flag. when set, flag enables “low profile" mode system bar or navigation bar. navigation buttons dim , other elements in system bar hide. enabling useful creating more immersive games without distraction system navigation buttons.
the system_ui_flag_visible flag replaces status_bar_visible flag request system bar or navigation bar visible.
the system_ui_flag_hide_navigation new flag requests navigation bar hide completely. aware works navigation bar used handsets (it not hide system bar on tablets). navigation bar returns view system receives user input. such, mode useful video playback or other cases in whole screen needed user input not required.
