ParcelGen

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 ?

CPOrm

Content Provider ORM for android. This ORM uses an android sqlite database as a backing store, but interactes with it using content providers. You use it like a normal ORM, by creating java objects, and then do all of you interations through the objects. And you get the added benefits of using it like normal content providers, so integration with list views and other components are simple.
