Hello, could you help me with mine, I did everything as described, but nothing happens, not the error, but also does not open the manager to attach the files. I have already attached the blocks previously, below is the screen of the (SITE) “Application” to which I want to attach the payment receipt.
Following changes made, but also without any success.
Maybe it’s because you have not enabled FileAccess property.
If it is disabled then FileUploadNeeded event will never get invoked.
Hi @vknow360 , I tried again, and got Error 601: No corresponding activy was found. However, this error only happens once, and then nothing else happens, it doesn’t open the file manager for sending, nor does it give any error.
Show the complete blocks.
Enable FileAccess just before GoToUrl method.
Because you have not defined what WebView should do to file upload callback if there’s an error with Intent.Pass an empty string to UploadFile method to cancel the request.

Image of the complete blocks below.
Apparently, everything is ok as suggested to me, I’m having a bit of difficulties with the Google translation, I’ll attach the .aia file to check, the problem is on Screen3.

I appreciate the help, waiting for reply.
Here is a working AIA file made using App Inventor so you won’t be able to compile it in Kodular:
CustomWebView_Permission.aia.zip (112.1 KB)
Hello, I did everything according to the model sent, continued the same ERROR 601 I’m going to attach an image of the blocks.
model block:
my blocks:
I’m in doubt, because your Fla stops when you click the button, and mine is when screen3 starts, does it have any influence?
I wonder why it looks different for me:
In case you uploaded wrong aia:
CustomWebView_Permission (2).aia (112.1 KB)

Sorry to bother you persistently, but I’m really lost in this error, I did as per the attached image, error continued.
see the video I recorded from the screen.
I uploaded the aia that sent me last, the blocks came a little messy, the first aia.zip was organized.
I will be very grateful for his help.
Post an apk then.
Yeah that was expected
Kodular is losing compatibility with App Inventor.
So better check in App Inventor.

I spent the day yesterday trying, but without success, changing blocks, so you sent me, but without success. Only this error 601: No correspondig activity was found. What can you think? Your project has an exclusive button to upload the files, right here, mine, it’s just a site being emulated in the form of an Application, isn’t it? application is all perfect, but there is no way to attach the receipt at all…
