Using both Parcelable class and Serializable in one class

Question

I have class Data with some properties, where one of the property is a class which implements Serializable and another one implements Parcelable, other properties is String.

And I want to make this Class (Data) implement Serializable.

Is there any problems during serialization of Data class with property which implements Parcelable, but not implements Serializable?

Answer 1

There are no issues as you don't introduce any new properties for the Parcelable implementation. Standard implementation merely provides you some helper methods describeContents and writeToParcel and a static CREATOR object, which will not be part of the Serialized content.

example:

 class MyParcelable private constructor(`in`: Parcel) : Parcelable {
     private val mData: Int = `in`.readInt()

     override fun describeContents(): Int {
         return 0
     }

     override fun writeToParcel(out: Parcel, flags: Int) {
         out.writeInt(mData)
     }

     companion object {
         val CREATOR: Parcelable.Creator<MyParcelable?>
                 = object : Parcelable.Creator<MyParcelable?> {
             override fun createFromParcel(`in`: Parcel): MyParcelable? {
                 return MyParcelable(`in`)
             }

             override fun newArray(size: Int): Array<MyParcelable?> {
                 return arrayOfNulls(size)
             }
         }
     }
 }
