Question about using the ListViewer component



Yesterday my app worked fine, now list viewers aren’t working. Did something change?

My app wont stop crashing

I have this problem since yesterday too
with list item click the app crash to white screen


Me too


Hi @Colby_Frechette,

Thanks for your question. Can you create a minimum working example and share it here so we can take a closer look?

Also, when you’re sending this can you also clarify whether this affects live testing or installing and if you are using anrdoid or iOS.



It affects both as far as I can tell. I did live testing on iOS and downloaded it and tested it on BlueStacks, neither of which work. I made a minimum, non-working example. Here


@Domhnall I’ve done some more testing. It seems as though setting objects to visible is the source of the crashing, not the List Viewers.


Thanks Colby - I’ve verified this on my end too and submitted a bug report.

As a work around for the moment, I’d recommend setting the height of the components you wish to hide to 0.

Apologies for the inconvenience.

I’ll follow up here when we get a fix for this.

Thanks! :smile:


If can help this is the error on android live test


Sorry for this :frowning:

We are actively working on this problem and if all goes well should have a fix out sometime later today.



Thanks for your help identifying the issue, we’ve fixed the bug. You may need to open the blocks editor in your project and move a block so that the code refreshes properly.

Thunkable X Admob not working in APK, but works in live test
:tada: A Thunkable ✕ release worth "waiting" for 2019-04-10

I have made an app with a loading screen at the beginning and every time I launch it on thunkable X it crashes within 5 seconds.

This has only been a problem since the recent update.

Any fixes yet?


Hi @Leon_Cummins, welcome to the Thunkable community. :wave:

In the absence of any other details, I’m going to guess this is the issue that’s affecting your project?

Paul was able to identify the cause and ship a fix for this yesterday:


You might also need to force quit and restart your Thunkable Live app for the changes to take effect.



Awesome, I’m glad you guys were able to fix the problem. Just a shot in the dark, can I get a cool free Thunkable t-shirt or something for helping? @Domhnall @Mark @paulmw


@Domhnall @Mark @paulmw The List Viewer problem is happening again. It still crashes the app sometimes. I will try further testing to see if I can find out what exactly causes it.


Thanks, @Colby_Frechette! If you can create a small example project that shows the problem, that would be ideal.
