Okay, maybe if someone needs it it might be useful. I found an elegant solution in KOTLIN:
Here Snippet from my repo.
And here my solution:

val Any.TAG: String
   get() {
    return if (!javaClass.isAnonymousClass) {
        val name = javaClass.simpleName
        // first 23 chars
        if (name.length <= 23) name else name.substring(0, 23)
    } else {
        val name = javaClass.name
        // last 23 chars
        if (name.length <= 23) name else name.substring(name.length - 23, name.length)
    }
}

I would like to create a class that provide a class tag everywhere in my kotlin project. I don’t want to use any library. A simple class/snippet could be fine to my personal project.
I want to use it to prevente everytime to create a String value TAG = “ClassName” and than use it in a log like:
Log.d(TAG,””)
