Hello, i am new here and also new in android studio. i have some knowledge in java, c++ but it has some time since that. so i am trying to make an application in order to control a led strip via android. i found a project at instructables that it is very close to what i want to make. the problem is that this project is from 2015. i am trying to troubleshoot the code but i am not so good at it. now it shows me an error here:

error: illegal start of type

    if (myBluetooth == null){

    ^

I'm afraid I won't be able to help with your coding question but I wanted to let you know that I added some [code]...[/code] tags to your post to make the content a bit easier to parse.
