In kotlin following code works with number and custom message

val defaultSmsPackageName = Telephony.Sms.getDefaultSmsPackage(activity)  
            val sendIntent = Intent(Intent.ACTION_SEND)
            sendIntent.type = "text/plain"
            sendIntent.putExtra("address", "sms:"+contactNumber)
            sendIntent.putExtra(Intent.EXTRA_TEXT, getString(R.string.share_msg_body))
            Timber.e("defaultSmsPackageName: "+defaultSmsPackageName)
            if (defaultSmsPackageName != null){ //Can be null in case that there is no default, then the user would be able to choose any app that support this intent.
                sendIntent.setPackage(defaultSmsPackageName)
                activity!!.startActivity(sendIntent)
            }
