Android :: WebView And HTML5 Features?
Oct 9, 2009
I am experimenting with Androids WebView[1] and its HTML5 features. I have written a little webpage with does the features detection like described here: http://diveintohtml5.org/detect.html
And now I see (I am on a SDK1.6 Emulator) that the LocalStorage, the WebWorkers and Offline Web Applications are not supported!
Does anyone know when these features will be supported? Or does anyone know the exact version (or build) of the webkit engine, that is used in Android 1.6?

I'm trying to use the HTML5 Geolocation features found in Android 2.0. However, it does not work in the browser or a WebView. I've tested in the emulator and on multiple devices. The code I have works in multiple other browsers that support the spec. Has anyone gotten this to work?

Is there any list which HTML5 features the WebView supports and which not? I am interested mainly in: 1) localStorage/sessionStorage 2) offline manifest 3) web sockets 4) web workers. Prior there was lack of those features (http://www.mail-archive.com/android-developers@googlegroups.com/msg60143.html), but in Android 2.1, first two should be supported, but I am not sure about 3 and 4. Is there any list of supported features or we have to test it on our own?

I recently tried out the applicationCache / offline web apps on Android 2.1's WebKit and unfortunately it does not work exactly like on a webkit on the iPhone. I was wondering how I can easily see what features should be implemented and if there is something like a roadmap?
Does that information somewhere exist?

I'm piecing together a cheapo app that amongst other things "frames" some of our websites... Pretty simple with the WebViewClient... until I hit the video.
The video is done as HTML5 elements, and these work fine and dandy on Chrome, iPhones, and now that we fixed the encoding issues it works great on Android... in the native browser.
Now the rub: WebView doesn't like it. At all. I can click on the poster image, and nothing happens.
Googling, I found http://www.codelark.com/2010/05/12/android-viewing-video-from-embedded-webview/ which is close, but seems to be based on a 'link' (as in a href...) instead of a video element. (onDownloadListener does not appear to get invoked on video elements...)
I also see references to overriding onShowCustomView, but that seems to not get called on video elements... nor does shouldOverrideUrlLoading..
I would rather not get into "pull xml from the server, reformat it in the app".. by keeping the story layout on the server, I can control the content a bit better without forcing people to keep updating an app. So if I can convince WebView to handle tags like the native browser, that would be best.

Does anyone know if there will be support for applications like that you download from the market to be written in canvas+javascript?
I know currently there is html5 and canvas support for the android browser but I am looking more for a solution for full screen games and such.

The HTML5 applicationCache in the 2.x browser is working well except for one problem:
when you force a cache update in JavaScript (window.applicationCache.update()) then it doesn't go out to the web to check the manifest it just throws the "checking" and then the "noupdate" events.
I imagine that eventually it actually checks the manifest online, but the update() is supposed to force it. any ideas on how to force an update or how old the manifest needs to be before it checks the web again?

I'm trying to get an html5 demo page working on Android 2.1, have tried both droid and nexus one with 2.1 but they only display the poster image, and do not play the video. Pressing on the video does not do anything. Resolved with the onclick handler on the video tag. Is it possible to use html5 video in the android 2.1 browser at this time? My demo page is working for both the iphone and the ipad.
The mp4 video: avc1, 29.97 fps, 380 kbps, 480 x 370
Audio: mp4a, 44 kHz, 64 kbps
Here's how the page is written:
<!DOCTYPE html>
<html><head><title>html5 test</title></head><body>
<video id="movie" width="480" height="370" poster="http://example.com/still.jpg" controls>
<source src="http://example.com/video.mp4" type="video/mp4">
Your browser does not support html5 video.
</video>
</body></html>

if this is a noob question, I searched quite a bit and couldn't find an answer. I'm developing a html5 app that relies on sqlite for local storage.I'd like for it to appear as an app icon on the iPhone/Android screen, what's the best way to do this? Ie can I write some sort of "wrapper" app to achieve it?

I've talked to a lot of people recently who say they are expecting to stop writing native mobile apps and start writing web apps once HTML5 gets more fully baked in mobile OSs. I just finished my first HTML5 deep dive, and I'm not yet convinced.
Will HTML5 work as a replacement development platform for native apps, or are there certain things that require targeting the native runtime?

I am trying to use gwt-mobile-webkit, particularly its location api. It works well with iPhone (both device and simulator) and Firefox and on G1 with 1.6 Android, however, it does not work on G2 with Android 1.5 on it. In result I am getting onFailure callback with Permission Denied error.
So it seems, that there is some geolocation API (gears or HTML5) in the browser available, but it just does not want to ask user for granting permissions. Do you know if there is any workaround or just enable it somewhere in settings?

I entered the Android world with a Nexus 7 (2012) edition recently.
I create some webpages which I want to make sure that it works in HTML5 browsers. The way I go about the testing is, I first create the webpages in my laptop, copy the folder to my Nexus 7, and open the index.html in the browser.
Now, I heard that Google Chrome is a HTML5 browser. But I am unable to open my html file in that when I open it from File Manager. I tried Dolphin Browser, but it crashes the moment it opens.
So, is there any other HTML5-only browser I can use for this purpose?

I have created an HTML5 'app' with a width and height 480 x 800 to be used as an android app.
Plan is that this can be scaled down/up for other Android devices to fit screen.
The app runs fine, but it is not being scaled to my device screen size. I have to scroll up/down and left/right on the every screen.
I have tried nearly every variation of the meta viewport tag with no succes (in the index.html file).

I'm working on a mobile web application and all phones don't casue any trouble with the soft keyboard and input fields, but Android does (tested on a HTC One).
Here's the problem:I've got a log in page with a log in form. When and input is selected, the soft keyboard appears. The soft keyboard kicks some elements up, which causes the lay out of the page to break. On iOS and Windows Phone, the soft keyboard kicks the whole page, so basically the DOM or body up to make room for the soft keyboard. The Android browser, however, lets the body stay where it is and only kicks some elements up, which causes the lay out to break.
Normal page:
When input is selected:
What the desired effect is (achieved on iOS and Windows Phone):
I haven't used any position fixed, only absolute on the page wrapper, header and header logo.
