Hi dear,

Could you show us the blocks related to ColinTreeListView?

Yes sure,
basically i am using Gsheet extension by app helper to load the data from the gsheet to colintreelist view here are the blocks:-

blocks(65)
blocks(65)925×1348 118 KB

steps are as guided by app helper tutorial

Important point : i just checked the old version aia file which was working earlier perfectly without any error now when i export i got same error so it means there is no fault in blocks as earlier it was working perfectly. so now what to do ?? is it the bug of kodular or what ???

5

How old are this projects? is the extension up to date?

It might be device specific
Which device anf Android version are you using for your tests?
Did you try on another device?

umm i am using vivo v11 pro , not yet checked with another device let me check an update by tommrow

Android version?
Taifun

Android 8.1 (Oreo) I GUESS, but i checked with latest model phone also same error

15

which means, it is NOT a device specific issue
Probably the author of the extension can check?
You can try to contact Colin Tree here GitHub - OpenSourceAIX/ColinTreeListView

Have you tried downloading the extension again and re-importing it? Maybe it got corrupted (unlikely, but not impossible).
Use “Direct download”

ColinTreeListView 2019.6.5 (Version 11)
The extension is now obsolete; it uses “MediaUtil.getBitmapDrawable” and that method no longer exists with the new Kodular, IA2, or other platforms.
It’s not a problem with the Android version, but with the compiler.
The developer should update and change the methods.
