scroll horizontally

[LIyoai]

When I open an article from heise.de I have to scroll horizontally. It has worked before, don't remember when it changed.

Using version 0.9.5.2.

i have the problem, too. it seems like the redirection to the correspondenting m.heise.de article does not longer work.

This issue can't be fixed by the Android App. Please use the "Open in Browser" option which is really smooth if you have Google Chrome installed on your device.

may i ask why? i'm sure it worked some versions ago. what happens technically? a redirect based on the user agent?

[David-Development]

I'm not sure but I think they changed the link in the rss feed to their non-mobile website (which makes sense).
I've just tested it again and if I click on "Open in Browser" the mobile site is shown. I've no idea why heise doesn't recognizes that the webview in the news app itself is a mobile browser, too.

The same problem exists within other apps with webview (e.g. Pocket). My stock browser is recognized as mobile, though.

Changing the user agent (with chrome dev tools) does not redirect to the mobile version. If it's not the user agent I've no idea how mobile devices are detected on this website...

I contacted the webmasters of heise.de and translated their response into english:

1. The RSS feed links to the desktop version of the website.
2. They changed the redirection to the mobile site some months ago from server-sided redirection based on the UserAgent to client-side javascript redirection based on the screen size and UserAgent string.

In details that means:
=> No redirection without JavaScript
=> No redirection when the screen width is more than 640 pixels (CSS pixels, not "device pixels"; includes a rotation detection)
=> No redirection if one of the following terms is found in the UserAgent: Macintosh, X11, Windows NT, iPad, Tablet, Nexus 10, KF.*Silk
=> No redirection for tablets

I figured it out: The mobile redirect somehow relies on the web storage api which can be enabled using WebSettings.setDomStorageEnabled(true). It is disabled by default. This is the reason why the redirect works with the android default browser (when not in private mode), which also uses WebView, but breaks in many other apps.
