Re: [xmlvm-users] --target=posix where to define main()

[Paul P. <bay...@gm...>]

It sounds like maybe you have multiple main methods, but have 1 particularly in mind for the C main?  XMLVM assumes there is only a single main method in the project & that is the one that is executed. If you have more than 1 main method, you will get an error.

Thanks,
Paul

Re: [xmlvm-users] --target=posix where to define main()

[Arno P. <ar...@pu...>]

XMLVM should generate a C main() if it sees a Java main(). Make sure 
your Java main has the correct signature and that it is included in the 
cross compilation (--in). Also one thing to note is that your Java 
program should have exactly one main() method (Java allows multiple 
main() methods and you have to specify on the command line which main() 
method you want to invoke. This happens implicitly in XMLVM).

[xmlvm-users] --target=posix where to define main()

[Ralf T. <ral...@co...>]

Hello,

I am trying to convert a Java project to posix but have no idea where the
main(argc, **argv) entry has to be defined. Inside my Java classes there is
one class containing the static main(args) method which should be started.
Trying to compile (to link) the generated stuff, currently ends with a
missing main() error.

Thanks for help

Re: [xmlvm-users] Date java classes not translated

[Arno P. <ar...@pu...>]

you might try to use the C backend (--target=iphonec). The C backend 
makes use of Apache Harmony and you might have more luck. In case 
something in missing, you will get a so-called red-class exception. The 
console log will tell you this.

Thank you Paul.
What is the standard beaviour of xmlvm when it meet a not supported class? It seems that the class is silently ignored, do you confirm it?

Can you suggest me the better way to add java.util.Date to xmlvm?

[xmlvm-users] Date java classes not translated

[Devone <de...@ea...>]

Hi everyone,
I migrated from android to iphone, but the Xcode generated project cannot be compiled due to this 2 classes non found:

#import "java_text_SimpleDateFormat.h"
#import "java_util_Date.h"

This is the command to translate the project:
xmlvm --in=/Users/devone/Documents/testsecure --target=iphone --iphone-app=testsecure --lib=android

and this the error after the Xcode run:
No such file or directory (for both files above)

My question is; is it possible that java.text.SimpleDateFormat and java.util.Date are not  included in android.jar or not supported by xmlvm?
What I'm doing wrong?


thanks in advance
Devone

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

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.

Re: [xmlvm-users] Using XMLVM with Maven

[<ju...@ed...>]

 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 ?

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

Re: [xmlvm-users] --target=iphonec NullPointerException

[Arno P. <ar...@pu...>]

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

10.5.5, XCode 3.1, IOS SDK 3.1

I will post back on the outcome.

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

[Arno P. <ar...@pu...>]

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.

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

Re: [xmlvm-users] Garbage Collection

[Arno P. <ar...@pu...>]

the Objective-C backend still uses reference counting. This will never 
change since there is no way to intercept alloc/init to make it work 
with the GC.

The C backend has a fully functional GC that gets bundled with the 
generated Xcode project (--target=iphonec). We already use the 
finalize() mechanism of the GC in the wrapper classes to release iOS 
resources.

[xmlvm-users] Garbage Collection

[Mark W. <ma...@ma...>]

Hi,

What is the current state of the garbage collection in xmlvm? Is a full garbage collector implemented, or is it limited to reference counting? 

Thanks!
Mark Wolfskehl

PS In regards to the person who was interested in .NET to iOS support, why not just use MonoTouch, which supports C# on iOS and Android?

Re: [xmlvm-users] XMLVM - java dependencies

[Arno P. <ar...@pu...>]

you can reference additional .jar files via --in=... Those .jar files 
will automatically be cross-compiled as well. As long as this .jar file 
is self-contained everything should be fine. Problems might arise if 
this .jar file references API that is not supported by XMLVM or if the 
.jar file contains native methods. My suggestion is to give it a try and 
include your .jar file via --in and see what happens.

Re: [xmlvm-users] XMLVM - java dependencies

[Alexandre B. <abo...@gm...>]

Hi XMLVM folks !

I am very interested in using XMLVM for translating a JAVA app to a 
mobile app (iphone/android).
My big concern is related to external dependencies: let say that my JAVA 
app depends on a set of .jar libraries, how XMLVM treats those to 
produce iphone- or android-compliant code ?

Thanks for your answers,

Best,
Alex

Re: [xmlvm-users] Standard Java libraries?

[Arno P. <ar...@pu...>]

yes, standard J2SE API is available when using the C backend. Depending 
on which API you use you may run into an unimplemented native method, 
but the majority of API is ready to use.

[xmlvm-users] Android SensorManager implementation

[Sam P. <sm...@gm...>]

Hello XMLVM community! 

I'm building an Android-iPhone game framework using XMLVM. I've been working on implementing device orientation processing for motion controls - with the vanilla Android SDK I did this by giving the accelerometer and magnetometer readings to SensorManager's getRotationMatrix and getOrientation class methods, which are not implemented in the XMLVM compatibility library. So, I took a look at the Android source and reimplemented them in my project! This works to calculate orientation on my Android phone and the cross-compiled iPhone app runs in the simulator, though I don't have an iOS device to actually test the orientation processing (Apple's emulators don't simulate hardware sensors). If this makes sense to anyone else would a contributor be willing to add those methods to XMLVM's SensorManager?
