If you simply want to check for permissions (rather than request for permissions), I wrote a simple extension like so:

fun BaseActivity.checkPermission(permissionName: String): Boolean {
        return if (Build.VERSION.SDK_INT >= 23) {
            val granted =
                ContextCompat.checkSelfPermission(this, permissionName)
            granted == PackageManager.PERMISSION_GRANTED
        } else {
            val granted =
                PermissionChecker.checkSelfPermission(this, permissionName)
            granted == PermissionChecker.PERMISSION_GRANTED
        }
    }

Now, if I want to check for a permission I can simply pass in a permission like so:

checkPermission(Manifest.permission.READ_CONTACTS)
