The size of the window is not configurable per activity*, but the orientation is. The two options in ARC Welder that control the window are:
- Orientation: This is either landscape or portrait, which will be the default orientation for your app. However, if you set a screenOrientation on your Android activity, this can override the orientation per activity, with the window rotating to compensate. There is a performance cost to rotating this way because the plugin will be rotated via CSS.
- Form Factor: This is one of phone, tablet, or maximized. This controls the overall size of your app globally.
* but for Chrome 42 and up you can use the metadata {"resize": "reconfigure"}
to allow arbitrary user resizing. Your app must be able to relayout with a variety of aspect ratios and resolutions in this mode.
