Error message in android thunkable app where i test my apps. The apps are working when testing in PC but not in my android phone. It was working before but sometime after it just wont work. I tried to create a new project but then the new project wont work to. I tried to delete the old project and create new one but it gives the same error message.

This error can be caused by many different things. You’ll need to debug your project. One way to do this is to remove blocks temporarily to see what is causing the issue (make a backup of the project first if needed). Or you may want to use a method I use:

> [@Debugging in Thunkable X (Video)](https://community.thunkable.com/t/debugging-in-thunkable-x-video/849471):

> I thought I’d share a process I use for debugging my projects. It involves creating a function that can be used over and over throughout the code blocks in order to help determine where things are going wrong, whether or not certain blocks are ever triggering, and what the values of several variables are. Here’s a screenshot of what I’ve set up: The real power comes from being able to quickly change the delay (and even set it to 0 seconds) or just remo…

You can still follow the debugging steps I recommended to find where the problem occurs. The differences between devices (e.g. processor speed, memory, etc.) can cause the same project to function differently.

I did so many things to make it work but in the end, I rewrote the code and use my phone to test it but still found the same error. So I deleted all my projects and remade it again, this time it works just fine in the web but still not able to complete it because every time the code gets complicated the phone version of the app gives me an error(web version works fine but not on the android phone version ). There was a time when even the navigate to other screen block wont work using a button. I even used the account of my colleague to test the navigate to other screen block using a button but the mobile app still wont work. So I rested for a day or two. Now the navigate to other screen block using a button is working fine, I guess there is a bug that got fixed during my rest. I try again today and update you on it

Are you using a data viewer? There is a reported bug in which if you pass a null value to the data viewer data source it shows the above error
