Kotlin Cancels getParceableExtra call when passing data class using Intent

Trying to pass a data class User from one Activity to another using Intent.

My putExtra looks like this using my observe fun:

val intent = Intent(this, MainActivity::class.java)
            intent.putExtra("userData",userData)
            startActivity(intent)

My get routine looks like this:

userData = intent.getParcelableExtra<User>("userData") as User

or

userData = intent.getParcelableExtra("userData")

My problem is that Android Studio strikes out the function. My User data class is marked @Parcelize. It all ends up getParcelableExtra.

I've add to my gradle build:

id 'kotlin-parcelize'

I've read several posts about Parcelable being more modern than Serialable, so that's the technique I'm using. All the posts are from 2018 or prior and many of them in Java.

How does one send an data class from one Activity to another using Intent?

Solution

  • Since getParcelableExtra (String name) is deprecated from api level 33 you can use getParcelableExtra (String name, Class<T> clazz) from api level 33

    In Your case use :

    val userData =
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
        intent.getParcelableExtra("userData", userData::class.java)
    }
    else{
        intent.getParcelableExtra("userData") as userData?
    }

    where TIRAMISU is constant value 33
