I'm working on a javascript framework that generates webkit browser pages which emulate a native app for Android & iPhone.
I'm using an iPhone emulator (iBBPhone -- very nice) to see how my pages would look on the iPhone and iPad. I was curious if there was something besides the Android SDK phone emulator that would simulate the Android browsing experience. I'm using desktop Google Chrome right now as a "pretend Android" browser but I'm not sure how alike they really are.
The Android emulator that ships with the SDK is a bit too slow to fire up on my box to be of great use in what I'm doing (even when starting up a saved image), and I was curious if there was anything else out there that simulates Android browsing. Thanks!
I think this Firefox plugin will let you display the site as it would show up in several different types of browsers. I know it supports iPhone so I imagine it will do Android as well. This page also talks about some other Firefox plug-ins that may be useful to you.
Chrome has a nice add-on named Ripple that does the job nicely I've found. http://ripple.tinyhippos.com/
These guys pretend to meet this need. Might be a good idea to check it out.

I have a very big problem and unfortunately I cannot find a solution. Help from some professionals would be really great. Thanks!
The little problem
I have a Angular Web App / Android App using Cordova. My app needs at least the Chrome Engine 50 to support all functions and looks right. Unfortunately I noticed that there are many devices that use a much older version. Also the devices do not use a common source for the Chrome Engine. Some use the Chrome Browser itself or the Android System WebView. In these two cases I can tell my testers, install the two things and then it works. Currently I check at the start of the app which version is installed and if it is less than 50 I show an info that users have to update ther apps / components particularly important here the two things (Chrome Browser itself or the Android System WebView). I rather say my users that they should update all ther apps because some hardware manufacturers have their own apps that include the Chrome Engine. That alone I find very unpleasant.
The biger problem
But it is worse with devices that have their own Chrome Engine built into the firmware. So one that you can not update at all via the apps update only just the hardware manufacturer of the phone can update them with firmware updates. So many cheap devices that don't get any more updates simply fall out and bring me possibly bad ratings.
What can you do?
Maybe someone has an idea? Because this way I can put my app in the store from Android 4.4 on but even 6.0 devices have older Chrome Engine versions in their firmwares. Can't I provide a chrome engine version or say I use it there from Chrome or from the Android system WebView? I'm really on the edge and need a clever solution.
I would be very happy about some help or exchange. Thanks a lot.
Best regards

I know both use the same webkit version (537.36) and both use the same javascript engine (V8), but are there any other major differences between them?
I have a webapp with automated tests for desktop Chrome but nothing for Chrome on Android. I'm trying to decide if I know it works on desktop Chrome do I need to go through the trouble of testing it on Chrome on Android, or are they similar enough that I should have confidence it works on both.
Thanks!
Main difference is that Android don't have Flash because of the HTML5 implementation, and also there's a lot of different screen sizes and users don't like to zoom in and out a pan and zoom again, so the best you can do is to create a web designed for mobile devices.
On the other hand, if your site is mainly HTML and Javascript, will work 100% on mobile Chrome. I have a HTML5 game and works equal in desktop and mobile.
Also, you can download the Android SDK and test your site in a bunch of different Android versions and screen sizes with the AVD, is like an official Android emulator.
The Challenge
I would like to create a simple website for:
iPhone 3 and 4
iPad
Android 2.2
– BBerry OS 7 and Playbook Browser
Symbian
Desktop Webbrowser
The Problem
Whats the "best-practice" for detect, optimize and deliver the Webapp for each device/screensitze? I know this is about HTML5, CSS3 Mediaqueries and JS. HTML5 Boilerplate is a good point to start.
But:
Should I detect Browser/Devices via backend/front? What are good
libraries?
How Do I detect different screensizes? What are good libraries?
etc.
Use Phone Gap as your starting point.
Depending on your use case, there may be other libraries you may want to pile on top of it, but basically Phone Gap is what you should start with.
My suggestion would be to use Sencha Touch. Its a very mature mobile app frame work with a very active community. They support any mobile that uses the webkit based browser which is everything on your list(Im not sure about the symbian browser).
Sencha 2 which will be released by the end of october will have its own native packaging library, so the use of phonegap wont be required. But it work well with phone gap if preferred.
Mobl is new language for the mobile web. just a look on it.
Adobe's Edge is the most refined HTML5 creator that also supports Android, iOS and Playbook (IMHO forget about Symbian, that's Nokia's half dead platform). BB7 uses webkit like most other desktop and mobile browsers.
Note that coincidentally Phonegap (that I see in other answers here) is part of Adobe now.
You can give a try to Titanium's new web SDK too.
And then look at this SO question which is very similar to yours and has lots of useful links in it.
We have an existing web site, and I've been asked to test its compatibility with mobile browsers.
I've installed the Android SDK onto my desktop PC. I'm able to view my localhost site in the emulator, and I have identified a number of glitches in the page layout which occur in the Android browser.
But since none of these issues occur in any desktop browser, I've been struggling with how to debug them. For example, in Firefox, it's very easy to use Firebug to see what stylesheets have been appies and to adjust them on the fly to see how it affects the layout. But I haven't found a way to do anything similar on the Android emulator.
The question is, short of trial+error, how do I go about working out what is causing those layout issues? Does the Android browser (or the Android SDK) have any kind of tools that are useful for debugging CSS? If so, how do I use them?
[EDIT] I haven't found a solution to this, so I'm throwing open the doors to the bounty hunters...
Weinre is probably the closest to what you're looking for:
If what you're looking for is something that allows you to tweak layout in realtime it should make you happy.

I found several options that appear as though they should work for you if an emulator/simulator will suffice or at least get you started. The benefit to this is that the Chrome Developer Tools appear to work with the add-ons!
Personally, I would much prefer to do this on actual Android hardware. In usage a touch screen handset is quite different to even the most accurate emulator; things such as gamma, pixel density, performance, touch interaction (are your links big enough?), portrait/landscape orientation and even the fact you hold it in your hand makes it quite different to the desktop experience. If you want to see how well your site works on mobile/Android, get a cheap second hand device to test on!
As for the debugging; I always include my own "log" function which creates a div#console if the firebug/browser console is unavailable. This works reasonably well for debugging on a handset with the caveat that it covers part of the content. You can then print out the current style of an object with something like
log(window.getComputedStyle(document.getElementById("myobj"));
Note: The above will not work in IE.
You may have already seen this, but the SDK Documentation Site has some basic information on developing and debugging web apps on Android:
Web Apps Overview
Debugging Web Apps
Hope that Helps!
I don't know how you detect a mobile device but I detect a client with the user agent. Because of this I can simply send a different user-agent string to test CSS which works fairly well.
For Firefox I use User Agent Switcher. Additionally I use the Web Developer tool not only to view all settings but also the Resize option to simulate the viewport width.
Apple's Safari has a developer extension and within also a User Agent Switcher. You can add your own User Agent string.
Chrome provides tools for doing this now. Just visit:
chrome://inspect/
With your device connected and ADB running - you can then use all of the Chrome web element inspection tools. This works with the browser, but also with any app that renders in a WebView (e.g. Cordova).
I want to test android mobile based pages on browsers like chrome or mozilla. Is there any plugins available so I can directly test them on these browsers without running them on device or emulator?
I created this chrome extension to help test. It's not a perfect replacement for actual device testing, but it's a start.

This site shows you one possible way to do it.

Once you have your user agent set you can just resize the window to be phone screen sized.
On Mozilla Firefox, you can use Selenium IDE to emulate clicks, typing and other actions. Personally, I have never tested it for mobile web applications.
