CustomWebView : An extended form of Web Viewer

AyProductions · July 17, 2022, 4:41am

Hello. I am having problem in displaying CustomWebView page.

Screen 1 and search button blocks:

when I type something in textbox1, and press search (button1), the app crashes.

You forget to make a WebView active.

AyProductions · July 17, 2022, 5:12am

Can you please guide me with blocks?

Use SetWebView block, example in #post243

Please try with the v12beta .

GigiG · July 19, 2022, 10:19am

I don't know how to update the Extension in AI2 ...

Peter · July 19, 2022, 10:34am

Just import the extension as you did the first time. It will update itself.

GigiG · July 19, 2022, 10:42am

Where is the 12beta ?

Peter · July 19, 2022, 10:52am

It was mentioned in this topic. Here is the link

GigiG · July 19, 2022, 11:07am

Imported but still same runtime error

GigiG · July 19, 2022, 1:51pm

Forgot to mention that I'm on a P10 Lite with Android 8.0 ...

GigiG · July 20, 2022, 7:34am

Could I try something else?

vknow360 · July 20, 2022, 1:09pm

Try in a different project or compile the project and check in apk.
The extension works correctly though.

GigiG · July 21, 2022, 8:21am

After upgrading to version 11 I got several errors on my CustomWebView objects

they was as below with version 7

vknow360 · July 21, 2022, 9:13am

That's I suggested you to try in a different project. Though you have a backup so it won't affect.
A lot of things changed between v7 and v11.

GigiG · July 21, 2022, 9:15am

Can I upgrade your extension step by step in order to not lose my work? I mean, upgrade from 7 to 8 and so on?

vknow360 · July 21, 2022, 9:30am

There is no way to upgrade extension without breaking blocks. You will have to either use older version or re-create broken blocks.

GigiG · July 21, 2022, 9:58am

mmmmm ... the older version give me the above uncoverable error. Why newer versions are not backward compatible with older ones?.......
Do you know a feasibe way to search for CustomWebView functions and objects inside AI2's Blocks environment?
Thanks anyway for your work
