Safe/Easy way to update Parcelable

Is there a common practice that can prevent missout fields in writeToParcel and Parcel contructor when introducing new member variables to a class that already implemented Parcelable?

The reason is because currently I have hundreds of pojo classes that is constantly changing (adding/renaming fields) during the development phase. I find it tedious to update Parceable every time I make changes, especially new developers who joined the team tends to miss out this change.

The legacy java serialization seems to have this well taken care.

Solution

  • Revisiting this in 2021. We can simply use the Parcelize annotation:

    import android.os.Parcelable
import kotlinx.parcelize.Parcelize

@Parcelize
data class Headlines(
    val title: String,
    val description: String,
): Parcelable
