I am getting this issue, I tried using kotlin coroutines and Async still getting the same Calling this from Your main thread can lead to deadlock,

Question

I also made another class that implements runnable to make a new thread still it's now working, Also tried with Aynctask. At last, I made a view model but still same issue. Anyone, please Help. Here is what I am trying to do

GlobalScope.launch (Dispatchers.IO){

                uploadFileToGDrive("/storage/emulated/0/Download/Ticket.pdf",this@AddPost)
                withContext(Dispatchers.Main){
                    Toast.makeText(this@AddPost,"I have gone Mad",Toast.LENGTH_LONG).show()
                
            }

        }



fun createFile (filePath:String):String{
        var file:File=File(filePath)
        val gfile = com.google.api.services.drive.model.File()
        gfile.setName(file.name)
        var mediaContent:FileContent= FileContent("application/pdf",file)
        try {
            var myFile= mDrive?.files()?.create(gfile,mediaContent)?.execute()
            var listOfPermission: MutableList<com.google.api.services.drive.model.Permission>? =myFile!!.permissions
            if(listOfPermission!=null){
                for (per in listOfPermission){
//                    Toast.makeText(this,per.toString(),Toast.LENGTH_LONG).show()
                }
            }
//            Toast.makeText(this,"Uploaded Files",Toast.LENGTH_SHORT).show()
            return  myFile!!.id
        }
        catch (e:Exception){
//            Toast.makeText(this,"Some Error Occured in Uploading Files"+e.toString(),Toast.LENGTH_SHORT).show()
        }
        return "Failed"
    }

I am running this function on a button click in an activity tried all the methods from coroutines to Aync and making new thread still getting the same issue.

Don't use GlobalScope, instead use lifeCycleScope. This might resolve the issue.
