If I understand correctly, every WebView based implementation needs WebViewClient.
But looking at the source code for Android 2.2's browser, I can't find any mention of WebViewClient.
How does it work if it doesn't use it?
If it does use it, where is it "hiding"?
It is implemented inside the tabs (see Tab.java).

I use PdfRenderer class to render pdf. However, the problem is that in this approach I can't make the hyperlinks in the document clickable.
Is there any better way to render pdf in android application?
I am aware of using webview with google docs, but I want the app to work offline so this solution is not suitable.
Try using pdfjs that is used by Mozilla.

This method works for sure on Android 4.0 and above
I'm trying to solve a problem in integrating WebChromeClient and try to achieve this one below (If possible).
Mine:
Steps that I made: I create an Activity with WebView in it. And just reflect the Url in the toolbar as title.
How can we somehow fuse (Fuse maybe not the right word) this to our App? The onCreateOptionsMenu is from Chrome Browser as I noticed.
EDIT: I don't know the name of it, I thought it is webChromeClient.
I don't know the exact name for this, I thought it was webChromeClient - but it is Chrome Custom Tabs. The documentation for implementations is found here:
https://developer.chrome.com/multidevice/android/customtabs#whatarethey
Gradle: compile 'com.android.support:customtabs:24.2.1'
Chrome Custom Tabs is faster than Google Chrome Browser and WebView.
Customization is also included
The WebView is good solution if you are hosting your own content inside your app. If your app directs people to URLs outside your domain, It is recommend that you use Chrome Custom Tabs for these reasons:
NOTE:
If there is no default browser set, it will pop up BottomSheet to complete action using. I think this should not be. We must check if Chrome browser is installed and launched that instead of other browser.
For kotlin users, equivalent is implementation 'androidx.browser:browser:1.0.0'

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,
Simon
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:

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):

Happy Friday to all.
I was wondering if there is a way to open an external link within the app itself? I currently can execute a link, but it opens it in a browser. I would like to open a site or two within the app.
Can this be done?
Oh, please tell me it can be, because this is one of the reasons why I am creating my app in Eclipse instead of Dreamweaver...html can only limit so much stuff!
please and thank you help me figure this out.

Yes, you need to use a WebView and load the html into it yourself.
Note that by default a WebView only displays html content. The plugins and javascript are off, and it does not handle link clicks, or forward / backward navigation

You can use a WebView to open HTML pages inside your app. There's a nice little tutorial in the docs showing the use of its basic features.
You can use WebView, put it in your layout and load URLs to show websites inside your app.
Yes it can be done, you can use a WebView to load the content inside your activity.
