Cannot build file APK

Do_Choi_STEM · May 17, 2020, 10:38am

Dear all,
I built application to communicate with Microbit via IOPin
( view tutorial here: http://iot.appinventor.mit.edu/#/microbit/microbitiopin )
I tested with AI Compnasion, it run successfully. But I want to build to file .Apk, It warning error.)
I post error image warning and file .aia here.
Could you help me to fix it ?
Five_Pin_data.aia (338.2 KB)

Unfortunately this Project is using the old MicroBit extension - I think it is most likely the reason why the compile fails.

The latest extension is available here:
iot.appinventor.mit.edu/#/microbit/microbitintro

Dear Chris,
This project is using newest Microbit extension and lastest Bluetooth LE Extension.
Your link provide is Simple Microbit extension, it does not have IoPin configure and read pin data.
I imported the file .aia from tutorial http://iot.appinventor.mit.edu/#/microbit/microbitiopin
and customize it. All functions are work well with AI Compansion, but I cannot Build it to APK file. The original file .aia is the same result.

That’s right, the latest Extension is simplified. I’m not sure why, possibly to do with the new Google Android security measures. I will assign your Topic to MIT.

Do_Choi_STEM · May 19, 2020, 1:31am

Dear Chris,
I got the newest Extebsion from Evan, I will test it with IOPIn and confirm later.

ChrisWard · May 21, 2020, 10:01am

Hi again - Any luck?

Do_Choi_STEM · May 21, 2020, 10:36am

Yes, it worked well with newese Simple Microbit extension.

ChrisWard · May 21, 2020, 2:15pm

Good to know!
