I've got a chrome kiosk application that talks to a local C# webapp. This is on windows.
Were in the final stages of development and once we turn on and run chrome in kiosk mode, we can't get to the devtools to say, look at an an error in the console.
Is there a way to open the devtools via javascript? I've looked doesn't seem possible.
Any other techniques/approaches possible to collect the log on request?
If you run Chrome with the --remote-debugging-port=9222 option it will provide access to DevTools at http://localhost:9222/.

I loaded a Chrome extension in Chrome using load unpacked in developer mode.
I know how to debug inside Devtools.
How does one develop and debug an extension using WebStorm where WebStorm's breakpoints in the extension's Javascript get hit?
No special support for debugging Chrome extensions is currently provided, see WEB-9708.
The IDE can attach a debugger to a running Chrome instance started with --remote-debugging-port option using Attach to Node.js\Chrome run configuration; see if it works for you
I am currently working on a HTML/JS application that will be embedded in an iOS and an Android app. Because the android app is not yet finished I am testing this on the chrome browser in Android. I fixed all issues there but when I open the same web app in the native browser nothing really works as expected.
So my question is : Is there a way to debug in a native browser on an android device?
In chrome this was pretty easy with remote debugging.
(Please do not advice me to use 'log' statements for debugging because that's not what I am looking for here)
And just to spill my guts : the Samsung Tablet's native browser is the only device that's causing me a headache!
Typing about:debug in the address bar of the native browser will toggle the 'Debug' options in the settings menu.
The 'Show JavaScript Console' option will allow you to see JavaScript errors in your webpage.
NB I believe the JavaScript Console will only be displayed if there is an error.
HTH
Nick.
The new Samsung Internet browser (I think you meant this browser with "Samsung Tablet's native browser") is now based on the Chromium browser and thus supports its remote debugging interface.
Enable USB debugging on your device as described here.
Then connect your device via USB (Oh, surprise!).
Visit chrome://inspect on your computers Google Chrome browser and you will be guided to create the connection:
Then you just have to click on the devices inspect link and an developer tools window will pop up.
More info like why there is an Samsung Internet Browser at all can be found here.
You can easily debug your web application with Web Inspector Remote (weinre).
Look at this post in order to find out how to install and use weinre.
I hope it will help you if this question is still actual.
If you have updated your device you can go to settings -> Debug -> 'Remote Debug Enable'
Once enabled you can debug the native browser just like you can debug chrome.
You can try vorlon solution too, it has a nice web interface & very easy to install
& It's free
But if you can't see clear console errors with volron, you probably want to use #Nick's solution, sometimes complex errors prevents even vorlon or weiner from catching them. So once you fix blocking these issues, probably volron will start catching them properly
I'm in the process of creating an Android test farm system, and while at it, I'm trying to find a way to inject javascript in an already open tab in the default browser.
I'm trying with
adb shell am start -a android.intent.action.VIEW -d "javascript:alert('Hello world!');" -n com.android.browser/com.android.browser.BrowserActivity
and while it works, it opens in a new tab.
Is there any way to do it in the current tab?
If you're cool with using Chrome, which is the default browser for newer versions of Android, you can use Chrome's remote debugging.
Once you've enabled this on the device (enable usb debugging + web debugging), you can connect by executing:
adb forward tcp:9222 localabstract:chrome_devtools_remote
If you hit localhost:9222 from your browser, you'll see the chrome dev tools for each one of your tabs. From here, you can do anything you could usually do in the desktop chrome inspector, including executing JavaScript from the console.
If this is not automated enough, you can write an app that uses a WebView, configure it to handle an intent where you provide arbitrary JavaScript, and use webview.loadUrl(js) to execute it.
I have an iPad with iOS 6.1 connected to a windows 8 machine. I would like to be able to debug some javascript code running on the iPad.
The safari on iPad has a web inspect option that needs the iPad to be connected by wire to computer and then can be accessed in Safari for desktop's develop menu. I installed Safari 5 for Windows but don't see the iPad detected in the develop menu.
Any other ideas ?
The Firefox Tools Adaptor allows one to use Firefox DevTools for Safari on iOS.

For remote debuggin I use Weinre.
Weinre has almost everything you need, but lacks a JavaScript debugger.
It has a WebInspector for DOM manipulations, network traffic, timeline, resources and a console.
Checkout this project on GitHub: weinre-remote-debug to setup weinre locally.
Another option described on this page is jsconsole.com. By appending a <script> tag to your page (or running a bookmarklet on your device) you get access to a JS console.
To start, go to jsconsole.com and run :listen in the prompt. This will give you a unique session ID and a script tag that you insert into your mobile web page.
Now, any console output that your mobile page generates will be streamed to the console open in your desktop web browser, including any errors!
It is certainly no replacement for a full web inspector, but it can get you out of trouble when you don’t have access to a Mac.

I'm developing a JavaScript application that needs to run on the Google Android Phone OS. Is there a way to enable the JavaScript Error/Debug console within Safari on either the Android Emulator or an actual device? If so any instructions on how to do so would be appreciated.
It looks like, with the Android 2.0.1 SDK you'll need to filter on "browser" instead of "WebCore"
A quick Google turns up this blog post (posted after you asked your question), that should at least let you see any Javascript errors via the Android Debug Bridge using the command:
adb logcat WebCore:V *:S
Not quite the same as a full debug console though.
On Android write about:debug on the address line when the current page is the page you want to debug. you will get access to the console.
I know your question is about Safari, but you might want to look into using Chrome instead. You can now use Chrome's desktop developer tools to debug and profile apps on your Android device.
Here's how:
On Android Chrome, go to settings -> Developer tools and check "Enable USB Web debugging"
On the desktop, run adb forward tcp:9222 localabstract:chrome_devtools_remote
Now on Desktop Chrome, navigate to localhost:9222.
You should see a list of the pages you have open on your phone. Click the one you want to debug/profile.
Detailed instructions are here
I have discovered that you can get this debugging information on the phone itself, without needingn to use adb or plug it into a computer, just download a log viewer.
Check the link for more info.
You can view the log and much more with weinre
From the Weinre docs
weinre is a debugger for web pages, like FireBug (for FireFox) and Web Inspector (for WebKit-based browsers), except it's designed to work remotely, and in particular, to allow you debug web pages on a mobile device such as a phone.
