Incorrect sizing after orientation change

[ChrisWTI]

Sencha Touch version tested:

• 1.1
• 2.0

• only default ext-all.css

The bug occurs in both 1.1 and 2.0

Platform tested against:

• iOS 5 (works fine)
• Android 2.x (not sure the version of the phone, but it worked fine)
• Android 4.0.4
• Android 4.1.1

The bug seems to only occur on Android 4.x devices

Description:

• When rotating the device from landscape to portrait, while an overlay is present, the resulting layout will make everything look smaller.
• What is happening is, say that in landscape orientation the width and height of the browser is 1024x496(this is from the Galaxy Tab). Then after rotation, the width doesn't update correctly. The width remains 1024, and the height scales accordingly with the correct aspect ration of the device. So in this case the width and height are now 1024x1488. So the content is drawn for a screen size larger than what it was previously, resulting in everything looking smaller.

Test Case:

See this URL : http://dev.sencha.com/deploy/touch/e...ays/index.html

Steps to reproduce the problem:


This MUST be done on a mobile device. I have not been able to reproduce it in Chrome on a desktop. (tried resizing the window, doesn't have the same behavior)

• hold your device in a landscape orientation.
• press one of the "show" buttons
• rotate the device 90 degrees

Note: While I can consistently reproduce this bug by showing a overlay before rotating the device, I have found that the bug will also occur WITHOUT the overlay present. However, it is not reproducible consistently without having an overlay on the screen.


The result that was expected:

• Items on the screen should appear to the same scale as they were before the orientation change

The result that occurs instead:

• everything looks tiny

Debugging already done:


I have checked the values of some variables before and after changing the orientation of the device. The values I am showing here are from a Samsung Galaxy Tab.

	Landscape	Portrait Buggy	Portrait Correct
window.innerWidth	1024	1024	600
window.innerHeight	496	1488	920
window.outerWidth	1024	600	600
window.outerHeight	496	920	920
screen.width	1024	600	600
screen.height	600	1024	1024
screen.availWidth	1024	600	600
screen.availHeight	600	1024	1024
document.body.clientWidth	1024	1024	600
document.body.clientHeight	496	1488	920
document.body.offsetWidth	1024	1024	600
document.body.offsetHeight	496	1488	920
