"stereo effect" isn't descriptive. assuming have stereo video files (one left eye, 1 right eye) you'd play them in left sphere (seen left eye), , right sphere right eye. spheres offset interpupillary distance (ipd) - 55mm. (it'd whatever stereo videos offset by). so, might ask - happens when turn around? ipd goes negative. when or down? goes zero. welcome stereo video. note there ways around this, you're not going them gopro without lot of special processing. @ best can sync idp direction averaged lens separation video streams, you'll stitching errors. equirectangular format (i.e square video) isn't best, you'll wrong answer @ poles. not using sphere how evolve (but it's simplest solution till better one) ...

i have edittext view on relativelayout , , can capture soft input keyboard keycode keycode_enter (int 66) . key listener: myedittext.setonkeylistener(new view.onkeylistener() { @override public boolean onkey(view v, int keycode, keyevent event) { log.d("softinput", "key received!"); } }); the problem soft keyboard displays key labeled "next" , need display "done". when (successfully) change key "done" using api: myedittext.setimeoptions(editorinfo.ime_action_done); the key listener stops working , can no longer receive anything in key listener. logcat doesnt show anything. literally stops working. when remove above line of code, works again key displays "next". i guessing clearing other flag required notify keys, using editorinfo.ime_action_next works perfect, soft key, of course displays "next". anybody knows workaround this? or reasons why happens? thanks. ...
