I have been facing with a serious issue since weeks! I want to track all the clicks done in a Android webview. I know, the solution is implementing WebViewClient, but that doesn't track the clicks done in frames!
Example -
When you open a website within google translate, webviewclient doesn't track clicks made in the translated page!
Secondly, even when using Android 3.0, when i open google.com, it shows Google instant i think, and i am unable to track that url!
I'll be very very thankful if you can help me with this.
Thanks

If it is your own Web content, you should track this in JavaScript.
If it is not your own Web content, it's conceivable you could cook up some general-purpose JavaScript for this and apply it via loadUrl("javascript:...") and addJavascriptInterface(), but I wouldn't know the details, as I'm not a low-level JS+DOM expert.
WebViewClient itself does not handle all scenarios, as you note, and it is the only pure Java solution I know of.

I'm developing a very simple Android application.
The application is just a webview linked to this OpenLayers3 docs.
There is really nothing special in the application. It is just a WebView,
but I get this rendering error when I open a popup:
This happen on a Honor7.
I noticed that if I disable the hardware acceleration the problem does not persist but in this way the performances are very poor.
Thanks a lot
This is probably due to the latest update to Android System Web View, that comes automatically from Google Play. If you uninstall the update, it helps. It is of course not a really good solution((((
i want to write an AccessibilityService which should help the user to fill forms. I saw the possibility to call Javascript code via WebView.loadUrl(). But since i've just the AccessibilityNodeInfo i only see that the WebView is on the screen.
After some research, i saw that TalkBackService is able to inject Javascript, and in a different post (Alternative way for communication between WebView and native) i saw its possible if i have a reference to the WebView-object.
Is there a way to execute JavaScript via such an Message or an Broadcast Intent in chromes WebView?
Would be really great if someone could help me!
Thanks a lot!
Chrome doesn't use a WebView, Chrome uses it's own rendering engine. While some of the code ends up being shared with the WebView (as in the two end up being compiled from the same source code) that's where the similarity ends.
I don't think there is a way to inject JavaScript into Chrome via an Intent - that would be a pretty big security hole (otherwise someone could inject a "send me all your money" JavaScript into your bank's page).
Accessibility is not my area of expertise so I can be totally off here but I believe newer versions of Chrome expose the web contents structure to the accessibility layer and therefore you should be able to do your thing without any custom JavaScript. I think you can check this using uiautomatorviewer: for me the tool shows html forms when I grab a dump of Chrome's UI. Is that not the case for you?
I have a code in my application to open a browser.
Sometimes I need to tell the browser to load another URL after a few seconds.
Is there a way to make the first browser to change the URL or I need to open a new one always?
Thanks,

The best way to achieve this would probably be to embed a WebView in your application, and then you can control it directly. Otherwise, as far as I know, you can't control a browser opened up via Intents. I could be wrong about that, but embedding a WebView and controlling it directly seems much more straightforward.
The WebView class reference:
http://developer.android.com/reference/android/webkit/WebView.html
Some notes on the WebView (less pertinent to what you're doing [this article pertains to writing HTML/native hybrid apps], but may have some useful information):
http://developer.android.com/guide/webapps/webview.html
I am trying to add a podcast and a youtube channel to my native Android app, but it seems it would be much easier if I just use HTML and access that media as it is on the web.
Is it possible to have an activity be HTML5 or a basic web view? If so, how can I do that?
Thanks!
Yes this is possible, have a look into WebView
http://developer.android.com/reference/android/webkit/WebView.html
A View that displays web pages. This class is the basis upon which you can roll your own web browser or simply display some online content within your Activity. It uses the WebKit rendering engine to display web pages and includes methods to navigate forward and backward through a history, zoom in and out, perform text searches and more.
You may find some performance/compatability issues but this is the easiest solution and one that I would do as a first step.
First, a disclaimer: i'm completely new to iphone, android or any mobile development. In the other side, i've been developing websites (php, javascript) for long time.
I have a website which is adapted for mobile and works great. But, there are some features i need such as prevent the screen from dimming (my site is designed to be used for many hours without user interaction while being permanently visible or for example being able to send notifications (with sound, etc., to attract user attention)).
This has lead me to consider a webview. From what i've seen, it's about creating a native app which just a webview (browser without toolbars) and using html and javascript to operate. It will use some native functions to perform some native actions (such as the ones i want).
I've searched around and i don't have a specific response to this: can i tell a webview to, permanently load the content from a remote site ? i mean, my site is php based (zend), with many jquery content manipulation. Can i tell him something like LOAD htp://www.mysyite.com and let him do everything else from it ? absolutely no local content applies, everything is remote. The webview would just be an "interface" to the website.
And additional question is: can i use jquery on it ? ajax calls ? geolocation ? i mean, in a browser i can, i just wonder if inside a webview i can.
I've read that phonegap does this. But most of the time, when taking about phonegap and about webview i general, i read people talking about loading locally the page not remotely in a permanent basis.
Finally, yes, i will build a native app in the future. But now, i simply don't have time to learn about android, ios and blackberry at the same time. Thanks a lot for your responses.
For Android only:

Yes, of course you can. Suppose you have a webview in an activity (it's really easy), you would load the web page something like:
WebView myWebView = .... // get a reference from XML or if you just created get its ref
myWebView.loadURL("http://www.mysite.com");
I would start with this API Guide article. Also, taken from WebView JavaDoc:
A WebView has several customization points where you can add your own behavior. These are:
Creating and setting a WebChromeClient subclass. This class is called when something that might impact a browser UI happens, for instance, progress updates and JavaScript alerts are sent here (see Debugging Tasks)
Creating and setting a WebViewClient subclass. It will be called when things happen that impact the rendering of the content, eg, errors or form submissions. You can also intercept URL loading here (via shouldOverrideUrlLoading()).
Modifying the WebSettings, such as enabling JavaScript with setJavaScriptEnabled().
Injecting Java objects into the WebView using the addJavascriptInterface(Object, String) method. This method allows you to inject Java objects into a page's JavaScript context, so that they can be accessed by JavaScript in the page.
Please be also aware that the webview is not that powerful as the phone's browser. Here is a SO thread where a friend posted an interesting question. You might find helpful the answers he got.
