I'm trying to write a code that can run on Android 1.5 and 2.0.1, but I have issues with the javascript engine used on Android 1.5. alert(localStorage); just hang on v1.5 while on v2.0.1 it alerts correctly. is there an unblocking way to do it or to detect the version of Android with javascript?

In Javascript/jQuery, how can I detect if the client device has a mouse?
I've got a site that slides up a little info panel when the user hovers their mouse over an item. I'm using jQuery.hoverIntent to detect the hover, but this obviously doesn't work on touchscreen devices like iPhone/iPad/Android. So on those devices I'd like to revert to tap to show the info panel.
I'm not highly familiar with javascript but I think this is the best way to accomplish my purpose. If not, please correct me. I have a licence text 2 buttons at the end. All of this is written in HTML in a WebView because there are some links in the licence. Now, I want that when the user clicks the "ok" button in the WebView, this triggers some javascript or listener that I can grab in Java to fire an Intent to go forward in the application. (The cancel button would do the opposite, but if I know how to do one, I can do the other. Does this rings any bell to someone? Any explanation or sample code is welcome.

I was wondering if there was one solution that would work for websites on both the iPhone and an Android phone.
I am going to develop an app runs on both Android and desktop, so UI will be built on html , javascript, css. User experience is very important, I am looking for a javascript UI framework has great UI, animation and response time. A great UI framework but slow (cause user annoying) is not acceptable in my case.There are many javascript frameworks available. Can you guys share the experience of how they behave on Android ？

View 2 Replies View RelatedI'm loading up a webview with some locally generated html and javascript.It makes calls to app methods just fine.But what's the right way to get data from Javascript back to the application? It's simple to have javascript call app methods, but any parameters specified in the call on the javascript side don't survive the trip (I just get null in the app).Gross hacks seem obvious (open a url and encode the data in the url), but that can't be right.You received this message because you are subscribed to the Google Groups "Android Developers" group.

Well, the following source code works fine for me (http:// whyandroid.com/android/206-using-webviews.html):
This is not called on the UI thread. Post a runnable to invoke

My problem now is to use a parameter for the JavaScript function.
Let's assume I've got some XML (just like AJAX somehow).
I need to escape it just like the iPhone / Objective-C command stringByEvaluatingJavaScriptFromString does.
I'm debugging a Javascript+HTML app. All the content is in ./assets.
The app works fine in Firefox, Safari and iPhone (over the web).
But in the WebView, I only get: D/WebCore (626): Console: undefined line: 0 source: undefined
I need to debug this code. Could I either: - enable more debugging in the WebView? though I think this needs to be done in the framework. or: - set up a desktop WebView equivalent where I can run a Javascript debugging tool?

My app uses a WebView widget to load ads from Google AdManager. AdManager gives you an HTML snippet, which is 90% javascript to call their server for the image to load.
I put their html snippet into a string and use String.format to add in several variables that AdManager requires.
I enable javascript on the WebView (webView.getSettings().setJavaScriptEnabled(true);)
I load the string into the WebView (webView.loadData(myString, "text/html", "UTF-8");
result: the ad never loads (although the WebViewClient shows serveral .js resources loading).
If I take that exact string and create a file and then use webView.loadUrl("file:///android_asset/test.html"), the image loads properly.
Why would loadUrl work but loadData does not?
I've verified that javascript is running. I injected a little script to write out a text string and it works.
I am very new to both android webkit and javascript. I have a web page with 3 links (say A,B,C). When I open that page on my PC browser(Chrome), and click on the links, A opens in the same browser window whereas B and C pops up a new window. In my application I am loading the original URL in a WebView. I have implemented my WebViewClient and overridden the shouldOverrideUrlLoading. I am getting the call to shouldOverrideUrlLoading whenever I click on A, but not getting it when I click on B or C?

I put a webview in my application to visit a webpage which includes some javascript functions, my purpose is when users click a link in the webpage, it will start a new activity in the application. I've written "webSettings.setJavaScriptEnabled(true);" in my source codes.
It works well in most of the time, however sometimes it doesn't work, there is no response when users click, and I don't know why because the environment is not changed at all.
I'm trying to very quickly port over an html application with plays sound (with soundmanager2) to a native android app using WebView. From my research, I haven't seen any evidence that sound, such as mp3s, can be played via javascript or any other methods using WebView.
My goal now is to quickly port over the html app and then eventually create a truely native application without using WebViews.
If anyone has been able to successfully implement playing audio using WebViews and Javascript or if this is just not possible at this time.
HelloWebview code (and other WebView code samples) all result in "web page not available" error. Javascript is enabled. Permissions set for INTERNET, ACCESS_NETWORK_STATE, CHANGE_NETWORK_STATE in Manifest.xml. Does not work on either emulator or device (Samsung Moment -- Android 1.5). GOOGLE.com comes up on both emulator and device. I have looked for s solution for this for several days. I'm a real newbie to Android, and a pretty new user of JAVA but can follow an example / sample.

Something along these lines: var javaScriptObject = {"field1":"string1", "field2":"string2"}; JavaScriptInterface.passObject(javaScriptObject); How would such a call be captured on the Java side? I have no problem setting up the interface to send a string, but when I send an object, I receive null on the Java end.
