Android :: WebKit Capabilities
Sep 2, 2009
Android platform and actually mostly interested in the browser. I created http://www.jqtouch.com/ in hopes of developing a web-based cross-device application framework — but I'm running into a lot of issues with Android. Does anyone know of any good resources which describe the features/implementation of WebKit on Android? At first glance, it appears it doesn't support HTML5, nor certain -webkit CSS3 extensions like gradients or transitions. Does support certain other WebKit features like opacity, etc.
Most of my searches are coming up futile, because I end up seeing generic info about Android having WebKit, or technical pieces specific to embedding WebKit in native apps — but no good documentation on general WebKit features available. Again, I'm new to the platform, so I apologize if this information is in the clear...

Is there a way to get webkit running in the background , or even small enough for the user not to know that the webkit browser is running? Basically i want to use this to have java and javascript integration while using the android UI.

I'am looking for a way to have a webview content selectable in the very same way as the stock browser does.
I should note that Dolphin HD shows exactly the same text select functionality as the default browser (same icons, animation, etc), so it really should be possible. But I can't figure out how.Until now, all i found was this function, which kind of work, but doesn't allow the user to expand/shrink the selection.I just discovered that long touch copy/paste is part of HTC Sense, not Stock android. Still, it'd be useful to find out how to enable that on a webview, even just for HTC users. Anybody knows ?

I wonder if it's possible to use webkit/webview for UI instead of using the native UI (view,layout,activity,etc). Is there a way to catch/propagate intents to internal app when we use webkit/webview ui (probably through javascript)? The advantage of doing this is to provide a cross platform client that works in various mobile devices.

I am interested in displaying web pages with more than the 3 installed fonts. I tried the demo of installing fonts as assets and changing the typeface, but I am not sure if it applies to a Webview. I was able to modify the sdk and install more fonts in frameworks/base/ data/fonts. I can see those additional files when using the shell in / system/fonts. However, the fonts were not used in the internal web browser.

This doesn't seem to work in jqTouch or iUI. But I know it's possible because it works on my Droid when I go to deviantart.com . Anyone know how to do it?

Why isn't there a gas app for the U.S? I would think with having GPS capabilities, that someone would create one using Google maps and possibly using GasBuddy.com - Find Low Gas Prices in the USA and Canada for prices.

When viewing Web pages either in the built-in Web browser or in a WebView canvas, focusable items get the orange highlight ring as you navigate the page with the D-pad/trackball. A design team I am working with wishes to create some Web content, specifically for Android, where they handle their own focus highlighting via Javascript/CSS and wish to disable the built-in Android focus highlighting. In this case, the content is being viewed through a WebView, so I have some measure of control. I see some posts describing how to use ColorStateList, <selector>, and android:background to affect this sort of change, for a single View. How would one go about affecting this change for the contents of a WebView?

Is there a way to extend Webkit on Android? Can we write plug in for webkit in android? Can we do things like creating our own renderer for a particular type of data embaded in the webpage? Can we track user session or modify data stored in the browser cache/memory?

how to enable SVG support when building Webkit for Android? I saw an earlier thread from back in March about SVG being slow for the UI of apps, but I'd like to experiment with web content containing SVG, DOM manipulations, etc to see what the speed is like. Is it just a matter of turning on the compile flags for SVG support in Webkit or would there be a significant porting task?

I have a question regarding the meta viewport declaration in HTML pages. Please tell me if this is not the correct group to post to. I have been doing quite a few iphone specific websites and I always use: <meta name = "viewport" content = "width = device-width; minimum- scale=1.0; initial-scale=1.0; maximum-scale=1.0; user-scalable=no;" /> Now I tried a site that is using that declaration in the android emulator with a 854 x 480 resolution. Even with the declaration above its scaling graphics and text. I would assume that I have 854 x 480 at my disposal. Can somebody explain how I can disable any resizing? Never had any of those issues in the 1.x Android OS devices and iPhone OS.

All, How can we enable LOG messages in Webkit.
I wanted to enable some debug prints using log utility of Android in Webkit I added the following statements in my code.
#define LOG_TAG "webkit" include <utils/Log.h>
And the following line to test LOGV("Constructor CachedImage.cpp");
I am unable to get the logs. Should I enable with the following define. I even added liblog as one of the shared libraries during compilation.
#define LOG_NDEBUG 0 /* Is this required to get logs? */

When my site renders in WebKit on Android, addresses are parsed and an OnClick intent is assigned to them, but this behavior gets in the way of javascript I want to act when the text is clicked. Is it because my site uses MicroFormats for the address? Is there a way to disable this on the browser, so no automated parsing occurs?

Is not possible to use a cellular card on a laptop that runs the emulator to access the Internet? if the emulator can access the network if the laptop is using wi-fi or cables I am assuming it can still do the same regardless of what technology is used to connect the laptop to the network correct?

Is it possible to update WebKit behind the Android 1.5/1.6/etc (prior to 2.2) browser? I know latest nightly WebKit builds has great HTML5 support. So, my intention is to provide html5 video streaming (and other features) support on all those droids. Previously I was able to update WebKit engine on different devices with older Safari to meet my requirements (on any mac os x distros it's easy as updating WebKit.framework).

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?

There are return values and such that allow handling if SensorManager sensors and location providers aren't available, but what about the camera and microphone for audio recording? Is there a way to detect those in software, or are we just to assume that every device running Android (even the rumored set-top box) is going to have a camera and microphone and try to use them?
In the case of the camera, it would seem that Camera.open() returning null would indicate the lack of hardware. I don't know if that assumption is valid or not, though, considering it isn't documented as such.
In the case of the microphone, though, I don't see anything that could possibly be checked. The same goes for the camera if you're wanting to do video with the MediaRecorder class.

I'm planning a mini road trip this weekend and I want to use it as a way to test out the GPS capabilities on the phone? I'd like to be able to replace my Magellan entirely. The maps are a bit out of date and it would be nice to have one less device to carry around.
I tried both NDrive and GMaps. I was unimpressed with both of them. Both were much more difficult to program than my Magellan when I tried programming them manually. NDrive was confusing to set up in the first place. GMaps worked quite nicely with voice programming, but I have no clue what commands I've got beyond that. NDrive didn't support this at all. On my Magellan I can give voice commands and have it pull up the POIs at the next exit so I can see not only where the next gas station is, but where the next gas station is after that. (Extremely useful if you're on an eighth of a tank and don't know if you must stop at this exit or if there's another gas station 2 miles down the road.) The voice for GMaps is extremely annoying.
I prefer free of course, but I'm more than willing to pay for a quality app if I can test it out before hand and make sure it does what I need it to do. Ideally I want the following:
Voice programming - I want to be able to say "Go to 1234 Main st" or something similar and it go.
Easy manual programming - I want to be able to easily enter destinations manually.
Trip planning - I want to be able to program multiple destinations. I recently went to Chicago. With my Magellan, I was able to program all the places I wanted to go before hand so I just had to click on the tourist trap I wanted to see and it directed me there.
Voice activation while driving - I drive alone most times. I'd like to be able to not have to take my eyes/attention off the road to search for the closest fast food place or gas station.
Integration with the other parts of the OS - I want it to do the standard things like mute the music when it gives voice prompts and turn it back up when it's done, mute voice prompts when the phone rings, etc. Any ideas on apps that will do all this?

I have built a website for mobile webkit browsers, there is an interval update to refresh data. But it turns out that the pooling refresh will stop at some time after run for a while (some minutes or hours, different by each time).I thought there may be something error occurred in my refresh data functions, but it works well in my laptop browser. I also tried to listen window.onerror event, but webkit browser seems do not support that event. What else can I do?And I am also doubting is there any problem with setTimeout and setInterval functions in mobile webkit browser?
