Display the version name in Kotlin
I am planning to display the version code on my xml files but I am have an error to display the text.
My Activity Code
val displayVersion = findViewById(R.id.app_version)
val appVersion = getString(R.string.app_version)
val versionName: String = BuildConfig.VERSION_NAME
displayVersion.text = "$appVersion $versionName"
My XML Code
Error Code
displayVersion.text = "$appVersion $versionName"
Maybe this error code are incorrect, because if ever I remove it the app will work.
