WebView stats!

Permalink | in Chromia on Android

After my recent post about updating Chromium WebViews I was contacted by Scientia Mobile, the company behind the WURFL database, and was offered actual real-life stats!

The situation is less dire than I assumed. About 90% of the users do in fact use the latest Chromium WebView. This number is based on several hundred million hits in December 2015, primarily from North America and Europe.

The problem with the Chromium WebViews

Permalink | in Chromia on Android

This week I received my first gift phone in ages, and since the sender wants me to test it I had to go through all my dozen Android phones and update them as well, so that I can run tests against the latest installed Chromia.

During this process I began to have serious doubts about the update process of the Chromium WebView especially, though the same problems also crop up with regular Google Chrome.

TL;DR: Although, as promised, the Chromium WebView can be updated as a stand-alone app from Android 5 on, I doubt if consumers actually do so because Android’s update process is badly broken. Thus a wide variety of WebViews may be in use right now.

Fair warning: if you are unable to contemplate the simultaneous existence of several Chromium versions running on the same device without suffering from existential angst the reading of this article is discouraged until you’ve consulted your psychiatrist.

Firefox OS is dead

Permalink | in Firefox Mobile

Last week, after reading this article, I tweeted that Firefox OS is dead. There was some pushback, since despite some important updates the OS will continue to be developed. However, an OS can be functionally dead without development being ceased, and that’s what I meant in my tweet.

On MDN keeping around outdated information

Permalink | in

I made a mistake in yesterday’s article. Not a technical mistake, but an MDN-reading mistake. The reasons why I did so are moderately interesting for MDN users, and suggest a few improvements for the site.

Styling placeholder texts

Permalink | in Coding techniques

A quick note on styling placeholder texts. Although it’s very easy, it turns out that both MDN and the usual go-to CSS Tricks article leave out one important bit of data: when setting the color you should add opacity: 1 for Firefox.

Styling and scripting sliders

Permalink | in Coding techniques

I’m currently working on my first real paid coding project in ages: PvdApp, a project of a friend of mine. (He paid for this research, so he deserves a link.)

Among other things, this project requires me to style and script sliders. There are several interesting points I would like to bring to your attention, such as a few underreported IE problems, the solution to Android WebKit’s appearance bug, and the proper use of the input and change events. And a quick syntax overview is always useful.

A new Device Adaptation spec

Permalink | in Viewports

Back in April I lamented numerous problems and vaguenesses in the current W3C Device Adaptation spec. One of the spec’s editors, Florian Rivoal, contacted me, agreed that the spec had some problems, and explained some of its less clear features to me. In return, I explained some features I think should be added to the spec.

Within about ten mails we had agreed on the features that a future version of the spec should contain. This article summarises our conclusions, and adds a few questions a future version of the spec should answer.

Also, this article serves as a quick overview of where the viewports stand today. Everything described below works in almost all browsers right now, with the exception of the @viewport syntax. So this is useful reading for every web developer.

Finally, there’s one question that must be answered: If you use (x-based) responsive images on a desktop site, and the user zooms in, should you load the higher-DPR images? The answer is important for defining desktop DPR and screen.width/ height.
