Hi,
modern Android browsers (Chrome & Firefox) are supporting the possibility to lock the screen orientation in fullscreen mode.
Here an action to use that from krpano:
Code
<action name="lock_screen_orientation" type="Javascript"><![CDATA[
var screen_orientation_api = typeof(screen.orientation) == "object" && screen.orientation.type && screen.orientation.lock;
var current_orientation = "" + (screen_orientation_api ? screen.orientation.type : (screen.orientation || screen.mozOrientation));
var target_orientation = current_orientation.indexOf("landscape") >= 0 ? current_orientation : "landscape";
if (screen.lockOrientation) screen.lockOrientation(target_orientation);
else if (screen.mozLockOrientation) screen.mozLockOrientation(target_orientation);
else if (screen_orientation_api) screen.orientation.lock(target_orientation);
]]></action>Call that action in the onenterfullscreen event:
Code
<events onenterfullscreen="lock_screen_orientation();" devices="android" />In the next release this functionality will be also integrated in the WebVR plugin.
Best regards,
Klaus
