What could be the reason for "attribute layout_constraintstop_totopof not found" when I build my project in android studio? I am a beginner

Issue

I am designing a UI from a tutorial online. The code doesn't underline any errors, the error pops up only when I try to build and test the app on my device.

Solution

you need to use the right attribute sometimes android studio did not show you the suggestion therefore you need to know the lower and upper cases use in XML. Below is the code that will solve your problem.

layout_constraintTop_toTopOf=""
