Hello,

I am building a revenge orgenizer app, where you can add revenges and mark them as done (A to-do list mechanic)

Well, i got this error when trying to export to APK to test it.:

Check your projects settings for empty properties.

DotManOne · September 26, 2021, 7:02pm

checked some settings, i just want to test the app so i didnt fill the APIs and stuff

i get this error now:
Error generating Yail for screen 5644758569451520_Screen1: : Cannot read property 'indexOf' of undefined. Please fix and try packaging again.

Again missing properties in project settings. Set minimun SDK level

DotManOne · September 26, 2021, 7:06pm

yeah its on 29 , thats the highest

dora_paz · September 26, 2021, 7:08pm

If you wish pm me your aia or post it here. Also you should set minimum sdk to API 29 because that means that your app will only run on phones with android 10+

DotManOne · September 26, 2021, 7:11pm

it is on 29 as i said.
what can i do to fix it?

dora_paz · September 26, 2021, 7:15pm

First set minimum SDK to android 6 and again check for missing properties

DotManOne · September 26, 2021, 7:33pm

the only missing properties are the APIs.

i just want to test the app, well the test function also doesnt work.

i still get the same error

’indexOf’ of undefined.

dora_paz · September 26, 2021, 7:35pm

I forgot to mention that I also checked and unchecked in General project properties Splash Screen, Show Lists as Json, RTL Support just to be sure that are configured correctly
