- Parcelable interface is a part of the Android SDK. Serializable is a standard interface of Java.<\/li>\n
- In Parcelable you need to set all of the data you need to pass in a Parcel object and also override the writeToParcel() methods etc. In serializable implementing the interface is sufficient to pass the data.<\/li>\n
