Web developer resources for Opera Mini 4

(Cross posted on dev.opera)

Today is an exciting time here at Opera - we're very proud to announce the release of the final version of Opera Mini 4! It's packed with great new features, totally free, and will make your mobile browsing even happier than the last version - download it here, and read about the new features here.

Over at dev.opera.com, we've produced a number of new articles to help you as developers and designers find your way around developing web sites that give a good user experience in Opera Mini 4, as well as other browsers out there, mobile and desktop!

1. Opera Mini request headers: Opera Mini 4 uses various custom HTTP headers, in addition to the standard ones - this article tells you what they are, and what you can do with them
2. Differences between Opera Mini 3 and 4: As you might expect, this article explains the main differences between Opera Mini 4 and the previous version - 3 - in terms of standards support etc
3. Safe Media queries: With mobile and desktop browsers having such varying support for media queries, using them effectively across browsers/platforms can be difficult; here we explore a solution to this issue
4. How to serve the right content to mobile browsers: This article looks at the different methods available to you for serving appropriate content to mobile devices, and what to watch out for
5. Designing and Developing mobile web sites in the real world, part 1: In this 2 part series, Brian Suda gives some real world advice hard won from his first hand experience of developing mobile web sites. 2 real case studies presented, with Brian exploring the issues his team faced, and how they were overcome. Other topics include standards support, identifying mobile users, and server-sniffing
6. Designing and Developing mobile web sites in the real world, part 2: Part 2 of Brian's informative article
7. Evolving the Internet on your phone: Designing web sites with Opera Mini 4 in mind: Ok, not a new article, but still very relevant. Written originally back when Opera Mini 4 beta 2 was released, this article covers Opera Mini 4's standards support in greater detail, and gives some useful design tips

If you have anything cool to share in terms of development/design techniques for Opera Mini 4, or other mobile devices, then why not write an article yourself? Send me your ideas and submissions at cmills[at]opera[dot]com. I hope you enjoy the new Mini browser!

Opera Mini 4 is having one unusual problem which did not exist in the previous version. Somehow it appears to have some problem with framed pages. Like, when click into a picture from google image search page, in the resulting framed page where u see quoted- 'see full sized picture', opera mini 4 is unable to retrieve any link that is there.
I would request developers to remove this bug on their next release

Just tested this. For some reason you can only open the full size image on Google Image Search by using the context menu. And then you have to reload the page. Hmmm, can anyone remember where the bug report form is?

On the Palm Os, there is a standard launch code for applications to call when they want the user's preferred browser to open a webpage.

Opera mini doesn't seem to support this (probably because you are thinking java rather than Palm).

It's an annoying missing feature though, and I regularly get users asking me why my apps and others can't open pages in Opera.

I would be delighted to write a free palm app that would let other apps launch Opera Mini. All you would have to do is check an agreed java resource on launch to see if you should go straight to that page.
(I have done a similar integration with another java app)

Any interest?

please contact me through hobbyistsoftware.com if you are willing to play nice :wink:

I like Opera. I have an idea for Opera Mini.
You can use (include in your browser) zoombar on the top or bottom side to view web-page in area placed under cursor. Horizontal zoom bar shall be useful to read the text.

Also, you can use readable semitransparent square area with visible for text zooming, with fullscreen page in backgroung of them.

I hate to click every time to zoom in and zoom out. Generaly, in the "zoom in" mode I cannot to view web-page content on the top, bottom, left and right side of the zooming square.

With my idea you can make your browser much more useful and user-friendly.
