CustomWebView : An extended form of Web Viewer

I want to evaluate the old Android 4.0 Tablet.
When installing the program I made with CustomWebView v12, it gives the error "There was a problem parsing the package" and does not install at all.

It works on higher Android 10+ versions.

@vknow360, do you know if your extension works with Web NFC?

I've tried it, but I get this message : Error: NotAllowedError: NFC permission request denied.

Best Regards,

Sorry, I do not understand your issue.. please elaborate...

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.

You can use SetVisibility function to hide a webview and vice-versa.

You can find an example here:

Thank you.

I got this Duplicate showFileChooser result error when I want to pick a file.
Here are my blocks:

how to load html in assets?
I tried file:///storage/emulated/0/Android/data/, but got ERR_ACCESS_DENIED.

Please help .

I have found solution for my above 2 questions:

the set FileAccess to true should be done after Webview be created, not before.

and then the goto url from assets also solved.


Hi Sunny

Given that CWV has a block to programatically scroll, could you add a block to lock scrolling? It's possible within the webpage itself, but only if it's your own of course.

LoadHtml function causes App to crash.

Hello Chippy

You haven't initialised Custom Web View correctly. See Post#289 in this Topic.

Also, you have not specified the viewport in your HTML:

<meta name="viewport" content="width=device-width, initial-scale=1"><form method="post"> Username: <input name="uname" id="mod_login_username" type="text" class="inputbox" alt="username" minlength="7" required=""><br> Password: <input type="password" id="mod_login_password" name="passwd" class="inputbox" alt="password" required=""><br> <input type="hidden" id="language" name="language" value="English">     Select a Service: <input type="submit" value="vPanel" formaction=""><input type="submit" value="File Manager" formaction="fmforward.php">     </form>

Thank you for the suggestion.
Here is the updated version:


Now extension supports localhost url as well. :grin:


That's very handy Sunny :sunglasses:
