Qr code generator

Please help, I'm facing problem of Qr Code generation with file Apk.
AppPP_Copy2.aia (145.7 KB)

what kind of problem?

If you are asking for help, I recommend you to make it as easy for others to be able to help you ...
You probably will get more feedback then...

which means in your case post a screenshot of your relevant blocks...

To download the aia file, upload it to App Inventor, open it, do some bug hunting for you, etc... this takes time, and most people will not do that...
Thank you.



Your app builds okay on the code server, so I guess you have a problem with one of your QR code extensions:

You should ask for help on the threads where you found those extensions.

I am unable to use the information obtained from another screen to create a QR code when installing the downloaded APK file."

Why are you using 2 different QR extensions?
What happens, if you remove one of them?
Also you could try to add the barcode scanner component into the project without using it... this probably might solve the NoClassDefFound error

Another test would be to create a one screen test project to see if it works there

Probably the author of the Qr extension @vknow360 is able to help?

Oh, thank you very much @Taifun . Now I can solve my problem. I just added the Sensors Barcode Scanner, and my app is now working fine.

Now you can remove Barcode Scanner component and still it will work fine.
