and thanks for your support!
Yes, you are right. It is the "Din...Go" project I was talking about. And sorry for the confusion about the index.html. At the time when I started this thread the index.html had some real/visual content. In the current version, however, we tried to narrow the problem down. That's why the current index.html doesn't make much sense on first sight at the moment.
Here are some news:
I removed the SD card and restarted the phone to go sure that it's not the SD card causing all these problems. So, everything I am referring to from now on is about my phone *without* SD card.
I uninstalled the app as you suggested and the re-deployed it in "Release" mode.
Here are our newest findings. In the index.hml you will find the following snippet:
$.cookie('token', 'test'); // Try to set a cookie through the jQuery Cookie plugin (we also tried pure JS, also without success).
alert('Cookie: ' + $.cookie('token')); //We get a "Cookie: undefined" message
Narrowing down the issues we found the problem in setting a simple cookie. This code fails on the mentioned Huawei Y300 (Android 4.1.1).
Surprisingly the dame code (actually the whole app) works just fine in the Graphite simulator, on an iPhone4 and 4s, and on a Samsung Galaxy Y (Android 2.3).
Does this ring any bell? Can this still be about permissions? I mean, is it possible that our app has no write permissions for cookies?
Thanks again for your help, Steve. We really appreciate it!
