I know, but the reason I still ask this question is I DID NOT UNDERSTAND THOSE ANSWERS. And I also know, that it's my problem and those contributors did well. Not blaming anyone.

I'm a beginner at Android Studio and those answers were definitely not rookie friendly. cause I've been starring at them for like 20 hours till now.

Any way, here's the code I have :

I am building an app using Capacitor to embed my website as the main portion of the app where there are portions that I want to be able to pinch-zoom (a photo gallery, for example). I've found answers about the Android WebViews and the HTML meta tag using the maximum-scale setting, like so, but after changing the meta tag the webview still doesn't support pinch zooming. Is there a way to override the Capacitor settings to allow zooming?

I am trying to use this in my Android app:

https://github.com/adblockplus/libadblockplus-android

bu putting this in my build.gradle:

implementation 'org.adblockplus:adblock-android-webview:4.4.0'

It works fine if I have jcenter() listed in my build.gradle repositories. But I keep getting the warning JCenter is at end of life and so am trying to switch to maven.

But when I replace jcenter() with mavenCentral(), it doesn't work and gives me error:

Failed to resolve: org.adblockplus:adblock-android-webview:4.4.0

I can see that the library is available on Maven here:

https://mvnrepository.com/artifact/org.adblockplus/adblock-android-webview/4.4.0

But yet Android Studio is unable to find it for some reason.

What am I doing wrong? I am very new to this so not familiar with repositories much.

I have a simple browser app. It loads some IP and displays it using WebView. I want to access the source code of the loaded URL and store into Android string so I can use it.

For an example :

Suppose it is loaded 10.0.0.1 and the webpage shows this.

So, I want to store that "HELLO THERE". And further want to process if string is equal to "HELLO THERE", a toast will be shown.

I managed to load the URL, and I know how to make Toast. The problem is, I am not able to store that "HELLO THERE" in string.

Solution Tried :

1. http://blog.weinigel.se/2014/03/05/getting-html-source-from-android-webview.html
2. Is there a way to get the HTML in a webview in an Android app?
3. How I get page source from WebView?

I have tried all of above solutions. But, none worked. It would be great if I get the answer using specific scenario of mine.

I am using WebView to turn my responsive website into a native app. Almost everything seems to be working, but the one thing I cannot get to work is my "Login with Facebook" and "Login with Google" buttons. Google One Tap Sign-in works fine by the way (after the WebView app has logged in to Google on a different page, i.e. Gmail), but the "Login with Facebook" and "Login with Google" buttons don't work. Please note that I have in fact configured my intent correctly (i.e. any returnURL or callbackURL with my domain name that would get called, would still be called through the app), but I believe these login API's from both Google and Facebook don't return the user to any returnURL, but rather just pass their results back to the javascript that initially opened the login popup.

The problem is the following (I think): At first, both buttons opened the link in a separate browser window (Chrome). When I complete the sign-in process (with either Google or Facebook), this browser window is closed automatically, but nothing is returned to my app (thus, my app doesn't know the user completed the OAuth process). So I decided to set webSettings.setSupportMultipleWindows(false). This at least fixed my problem with the Instagram API (because that also wasn't working), and it does also make the Google and Facebook authentication windows now open within the app (so I think I'm a little closer to getting this to work), but the problem is, the return data/result from the OAuth process is still not returned to my app. In fact, the Facebook login screen manages to close my app entirely once it completes (I guess the window.close() affects my WebView app as well, or something like that). For Google on the other hand, after signing in, the page stays white. Pressing back does allow me to go back to my app's Login screen.

Here are examples of what's happening:

Facebook:

Google (first time, the login process works, but after completing the signing in, we end up with the same white page as below):

Google (every time after that, once you're signed in to Google):

The javascript that handles the response in the website version of my app all works just fine! It captures the result from the OAuth call to Google or Facebook and handles the returned e-mail address and Google/Facebook ID's, and then logs the user in to my app.

My problem is probably related to: Android Google login not working inside WebView

But I couldn't get that to work. If anyone has a better understanding of this WebView technique or knows how to apply the solution mentioned in that topic to my situation, any help would be greatly appreciated!

I've also read: Google sign in not working android webview app

And several people in that topic have stated that I have to override the popup handling, but I have no idea how to do that...

Here's my MainActivity file:

progress bar will not stop and will load indefinitely.

fragment code

im trying to navigate from webview to fragment using navController, but it seems not working.

here is my code

I am trying to make a report from my data using templates. The PDF using WebView works perfectly fine until my data gets bigger than a certain number (1 more in a for-loop), then it only produces a single blank page. I've checked all possible answers here; this, this, this, and this, but no success.

Here is a snippet of my code:

I have a recycerview. it has item click event in onCreateViewHolder method and an imageview click event on onBindViewHolder method. Surprisingly while recyclerview loads for the first time first and last item click works after second click then after it works on every click if it is not scrolled.Again when i scroll the recyclerview then same happen for the first and last item like first load. I can not figure out what is the problem

Below is my recyclerview layout @+id/recyclerViewForFilteredCourses is the recyclerview
