So I’m designing a part of my application for the Galaxy Tab 4 with a 7" screen. The screen resolution is 1280x800. When I design my forms, is that the size I set the form to or something else?
It depends whether you are planning to support landscape, portrait or both. If you want to support both with the same layout, make the minimum size 800x800 and them make your layout work for both orientations. If you’ll be using one layout per orientation, make the minimum size match the orientations. If there’s any possibility of supporting other devices in the future, I’d use 768 as your minimums because it’ll easily adapt to 1024x768 screens.
Actually… You should make a test app that reports the width and height of the WebPage. It will probably not be the same as the pixel dimensions, as browser makers supposedly consider a logical “pixel” to be 1/72 inch with device held at arm’s length, or something close to that. Also, the page dimensions will be different with Chrome and Firefox, the browsers you need to worry about most on Android. And “browser chrome” (stuff surrounding the active area) varies between browsers and versions and with plugins as well.
Bottom line: a static layout isn’t going to work well. You’ll want to look at the space available and arrange things nicely to fit.
Good point.
