**EXPERIMENTAL** Support Parcelable types for Android

[joelittlejohn]

This came up on the mailing list, and sounds like it might be very useful for a lot of people:

https://groups.google.com/forum/#!topic/jsonschema2pojo-users/IX0g58VAS58

More details:

http://developer.android.com/reference/android/os/Parcelable.html

[joelittlejohn]

Draft implementation is complete, feedback welcome:

https://github.com/joelittlejohn/jsonschema2pojo/tree/parcelable

Note, this has only been tested with robolectric.

[joelittlejohn]

It would be helpful if someone could test this. Simply build a snapshot from this branch and turn on JSR-303 annotations to try out the Parcelable support:

<includeJsr303Annotations>true</includeJsr303Annotations>

(I've reused this config property for now, will create a new one when this appears to be working)

EDIT: I've made a proper config option now, use <parcelable>true</parcelable> to test this.

[jsuksl]

I found that the code lines below generate Parcelable classes which have the annotations("javax.validation.constraints.NotNull", "javax.validation.Valid" ) not available on the Android runtime

ruleFactory.getValidRule().apply(nodeName, node, field, schema);

((JFieldVar) generatableType).annotate(NotNull.class);

[joelittlejohn]

Are you able to include the javax.validation/validation-api jar? I really need to create a dedicated config argument for parcelable so that it can be tested more easily.

[jsuksl]

Good to hear your feedback.
As you suggested, adding 'javax.validation:validation-api:1.0.0.GA' to my build.grade resolves build errors.

compile 'javax.validation:validation-api:1.0.0.GA'

I hope to see new release with Parcelable support is available on maven repository soon.

[jsuksl]

BTW, would you consider to introduce new option(other than "includeJsr303Annotations") for Android Parcelable types support when it comes to release this in the future?
I think that includeJsr303Annotations and "Android Parcelable types support" are two different categories of features that deserve separate config options .

[joelittlejohn]

I've just rebased the parcelable branch against master and added a proper 'parcelable' config option. If anyone would like to test the parcelable support, just build a snapshot from this branch:

https://github.com/joelittlejohn/jsonschema2pojo/tree/parcelable

Then if you're using Maven, activate the parcelable support like:

<parcelable>true</parcelable>

gradle, CLI, Ant etc have an equivalent config option.

[joelittlejohn]

@jsuksl @premnirmal @LOG-TAG if you can give this a test and provide some feedback, this would be very helpful. I don't really know if the current implementation approach will work or not.

[jsuksl]

@joelittlejohn https://github.com/joelittlejohn/jsonschema2pojo/tree/parcelable works fine. BTW, I see jsonschema2pojo-maven-plugin build fails.

[joelittlejohn]

Thanks @jsuksl! Could you give me some details of how you tested this? What kind of object did you parcel and what environment did you use to test this?

Also, I don't see any problems with the build when I run mvn clean verify on the parcelable branch. What build failure did you see?

[jsuksl]

I used jsonschema2pojo built from https://github.com/joelittlejohn/jsonschema2pojo/tree/parcelable to convert json schema files(30+) to POJO classes which contains information for UI components. few of the POJO classes are used as a parameter value( "http://developer.android.com/reference/android/content/Intent.html#putExtra(java.lang.String, android.os.Parcelable)" ) and can be written to and restored from Parcel successfully.

I encountered the errors below when I run mvn clean verify

[joelittlejohn]

Hmm, I think the assertThat call is confusing the compiler as the varargs are making it ambiguous. I don't see this error when I run the build though. Could you let me know your OS, JDK version and Maven version?

[jsuksl]

Here you are

The errors have been resolved after letting maven use JDK 1.7

[joelittlejohn]

I've included 'experimental' support for this in master. People can give this a try and provide some feedback if they have problems.

[jsuksl]

thanks!
