Thread: [xmlvm-users] XStream : Android -> iOS

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Has anybody attempted to cross compile a java (android) application  
which uses xstream (1.3.1 or the more stable 1.4.2) ?

I am not familiar with xstream, but the question whether XMLVM can 
cross-compile this to iOS largely depends on the API that xstream itself 
depends on. XMLVM supports XML API (including JAXP) so chances are 
pretty good. The only way to know for sure is to write a little iOS 
Hello World (take one of the tutorials in xmlvm/tutorial/ios/helloworld 
as a basis) and give it a try. Note that this will definitely *not* work 
with the Objective-C backend. You need to select --target=iphonec.

Thanks Arno.
Will get my Leopard VM image set up and do as you suggest.

aside 1: XStream is I think the best bang for the buck if u need to  
just de/serialize objects/xml.
If you're interested, just look here:
http://xstream.codehaus.org/

aside 2 : With this darn Mac OS X environment...is this combination  
reliable for XMLVM purposes ?:
10.5.5, XCode 3.1, IOS SDK 3.1

I will post back on the outcome.

Best Regards
Julian

I looked at it and I think there might be a good chance it works out of 
the box.

I'm not sure if the Xcode project that XMLVM creates is still compatible 
with Xcode 3.1. Panayotis might know.

Arno

My xmlvm trunk version is 2118 (I updated today).

I created a skeleton project:
xmlvm --skeleton=android --out=/path/to/TestAndroidXMLVMAppFolder  
--app-name=TestAndroidXMLVMApp
No modifications whatsoever to the skeleton project.

unfortunately the online doc is a little out of date. After creating a 
skeleton project you should use the generated ant-script for 
cross-compiling your app:

ant run-Xcode

 From this thread:
[xmlvm-users] --target=iphonec NullPointerException
https://sourceforge.net/mailarchive/message.php?msg_id=28772376

Arno has identified that an invocation of ant target 'run-XCode' is  
required against a skeleton project in order to avoid this error:
>> [02/01/12 19:07:18.633]    ERROR: Couldn't create node for  
>> android.app.Activity

Running this ant target on a skeleton project does create all of the  
necessary artifacts to avoid this error:
xcode things are generated nicely.

NOW, I have *existing* Maven projects against which I have run the  
xmlvm-maven-plugin [0.0.1-SNAPSHOT] (which is itself built locally).
HOWEVER, during the build I see  the same error as that discussed above:

[INFO] --- xmlvm-maven-plugin:0.0.1-SNAPSHOT:generate-xmlvm (generate)  
@ AndroidXMLVMXCodePOC ---
[INFO] Running XMLVM with command line:  
[--in=/path/to/project/target/classes,  
--out=/path/to/project/target/AndroidXMLVMXCodePOC, --target=posix,  
--app-name=AndroidXMLVMXCodePOC, -DXcodeProject=iphone,  
-DBundleIdentifier=apkg.AndroidXMLVMXCodePOC,  
-DBundleVersion=0.0.1-SNAPSHOT, -DPrerenderedIcon=false,  
-DStatusBarHidden=false, -DApplicationExits=true, --debug=warning]
[02/05/12 15:38:34.516]    ERROR: Couldn't create node for  
android.app.Activity

So, my 1st, and more important, question is:
Is it possible to have the necessary boilerplate artifacts generated  
during this process of converting a maven project ?

SECONDLY, I notice the -DXcodeProject-iphone argument, but from Arno's  
response in the thread:
[xmlvm-users] XStream : Android -> iOS
https://sourceforge.net/mailarchive/message.php?msg_id=28770943

Arno says
<quote>
--target=iphonec is required as the obj-C backend cannot support this.
</quote>

So, my 2nd question is : does -DXcodeProject=iphone use C or Obj-C backend ?

This seems to indicate that you are not compiling against the Android 
Compat Lib. Sorry, but there is no support for Maven. Again, I would 
suggest you start with a fresh skeleton project and then move your code 
over.

> So, my 2nd question is : does -DXcodeProject=iphone use C or Obj-C backend ?

This property is not related to the selection of the backend (which is 
determined by --target) but the kind of Xcode project that should be 
created. The -DXcodeProject=iphone specifies that an iphone project 
should be created (and not an ipad project). See --help for details.

Arno

He seems to be using my xmlvm maven plugin from https://github.com/tisoft/xmlvm-maven-plugin

I have never tested the plugin for an android build. I will try to add support for android builds in the next days.

I have added a sample that shows how to use the maven plugin with android:

https://github.com/tisoft/xmlvm-maven-plugin/tree/master/src/test/resources/xmlvm-android-test

Hope that helps.
