How can I use findViewById method inside AsyncTask?

I have an AsyncTask to execute while trying to connect the phone to a Bluetooth device, I want to change an icon from a button if it connects successfully

(I'm new to Kotlin programming)

Main Code

enter image description here

I would be very grateful if anyone could help.

Solution

  • Replace this with line 146 val blueBtn=this@MainActivity.findViewById(R.id.blue_btn)
