ParcelGen

Android Arsenal

This project combines Java Annotation Processing & AST modification to generate Parcelable boilerplate code before compilation. The main aim of this project was to explore undocumented Java AST modification.

This library does not bring any runtimes to your project - all code is generated before compilation. Changes occur only in annotated object.

Setup

Add dependencies to you project:

compile 'ru.noties:parcel-gen:1.1.0'
apt 'ru.noties:parcel-compiler:1.1.0'

Annotate a class that should be Parcelable with @ru.noties.parcelable.ParcelGen.

Supported types

  • byte
  • int
  • long
  • float
  • double
  • boolean
  • String
  • Enum (no array support)
  • Serializable (no array support)
  • Parcelable (with array & List or ArrayList support)
  • CharSequence
  • List & ArrayList

Changelog v1.1.0

  • Added calls to super if parent is annotated with @PacelGen
  • Added more supported types (CharSequence, Lists)

Drawbacks

As long as IDE would not know that an object will magically become a Parcelable after compilation it will not let you use it as it's one. There are two possibilities:

  • Simply cast to Parcelable when it's needed (Bundle.putParcelable("key", (Parcelable) myAnnotatedWithParcelGenObject);
  • Implement Parcelable in your object, add valid describeContents & writeToParcel(Parcel, int) methods & leave them there. ParcelGen compiler will replace them with fully functional ones.

How to improve library

  • Add support for arrays of Enum & Serializable ?
  • Add more of supported by Parcel types ?
  • Call super.writeToParcel() & from constructor ?
