how do i decompile a thunkable app correctly
i tried to decompile and i think android studio is on drugs [unable to find]
if you are wondering why would i decompile it?
i need to add custom code to the main activity

Unfortunately, you are likely to be on your own on this front. I haven’t seen many users decompile the apps successfully. I’ve not done it.

You may run into issues here but good luck! If you do figure it out, be sure to circle back around and share the result!
