Yes it’s Pura Vida’s Taifun extension (WiFi Manager Extension. Version 2a as of 2016-08-11 App Inventor version nb150 and Companion version 2.38.).
- this is excerpt from Screen1.Initialize. This works well in Thunkable Live run, as well as in the installed app from apk. Aim is to record the mac address of device where app is installed, as a kind of device id, but for test I only display it…
It should be easy to repeat the error:
I originally intended to put this on other screen named “licS” (I have 6 screens), and if I do that again (set label text on “licS” screen to wifi mac), then interestingly there is no crash in Thunkable live run, but in installed app, after I return from licS to Screen1, I get crash notice “Unfortunately, app has stopped” with ok button. In both cases I see WiFi mac.
I change the screens the right way, I mean I close the other screen, and use Screen1.OtherScreenClosed. to see where I’m returning from.
