this is my first Android/Kotlin question and new to android so please have patience with me.
In this android book which is listed in the title on chapter 37 when I try to use the "seekBar" to make text bigger/smaller the app crashes. I am used to Swift/Xcode where when the app crashes the program goes right to where the crash is caused, and android doesn't do that.
Can anyone point me in the right direction to how I can customize android studio to act like Xcode? But as far as the "seekBar" here is my code below... if more files are need please ask and I will provide.
Also, if you look at the bottom of the code and see the function "override fun onStopTrackingTouch" this code isn't recommend in the book to implement in the file. If I don't implement this, there is a error in the file.
Again, please have patience with me since I am new to android and need help.
