Dear Member of XMLVM List, First of all, I'd like to say I've seen Dr. Arno's presentation from February 25, 2010, and I'm now very interested in your XMLVM project. I've already downloaded the code, and I tried some work with my already developed Android Java Code. I wasn't very successful in these attempts, but that's a good start. Anyway, I'd like to ask you some few questions. I'm interested in porting my already written Android Java Code to Apple Object-C iOS code. 1- To use XMLVM, do I have to start my Android Java Development from the beginning using your iOS Java Classes? 2- If the answer for question 1 is positive, is there anything I can do to change easily this code and port it to the XMLVM iOS format? 3- If the answer for question 1 is negative, can I use all the ANDROID library, or only the features that you've already implemented for your XMLVM project (file Android .java that I can see in the XMLVM project directory)? Thanks in advance for your help, and congratulations again for this beautiful work/initiative. Best regards, Alexandre Flores de Almeida Brazil |

yes, the patch only changes XMLVM_ISA() in xmlvm.c. My tests seem to be running OK. I cannot deduce anything from the bad access error you reported. This could be something completely unrelated. Can you please try and come up with a small, self-contained Java sniplet that reproduces the error? Without that there is nothing I can do.

Thanks, I tried this but I applied manually since I have a somewhat older version. As far as I can tell the only significant change is in XMLVM_ISA.

Looking further at the code its possible that the code that is failing is something like o instanceof byte[] which is also in that same segment. A workaround I was able to apply checks for the bug and tries a cast which is caught seamlessly detect the type (can't use reflection here). >________________________________ > From: Shai <sha...@ya...> >To: "xml...@li..." <xml...@li...> >Sent: Sunday, January 22, 2012 9:12 PM >Subject: [xmlvm-dev] Object array instanceof problem > > >Hi, >I just ran into an issue with: >o instanceof Object[] > > >Where o is an array of Object subclass.

Hi, I just ran into an issue with: o instanceof Object[] Where o is an array of Object subclass. This works as expected in Java but doesn't work with the C backend on iPhone (I'm not on the latest and greatest since we are approaching feature freeze on the iOS work). Is this something that is fixable in XMLVM? Are there workarounds? Thanks. |

I have created a patch which at minimum addresses this issue. It is mainly a direct transformation of the equivalent UIImagePickerController code to UIImage. Please tell me if you agree. |

... moreover, has anybody checked the selector?
In ObjC code I can see something like
sel = NSSelectorFromString(@"imageDidFinishWritingWithError___org_xmlvm_iphone_UIImage_org_xmlvm_iphone_NSError_java_lang_Object:::");
It is interesting because in the iOS documentation it says:
This optional method should conform to the following signature:
- (void) image: (UIImage *) image
didFinishSavingWithError: (NSError *) error
contextInfo: (void *) contextInfo;
which of course doesn't conform... |

I think there is a mistake in the location of function UIImageWriteToSavedPhotosAlbum
Now this function is an instance method of the UIImagePickerController class.
From the signature of the function this should be an instance method of UIImage, and namely
public void writeToSavedPhotosAlbum(UIImageWriteToPhotoAlbumHandler target, Object context)
probably it should be moved there?

there is a patch that has not yet been committed to the repository: http://xmlvm-reviews.appspot.com/169001/ It adds the Java iOS API for the camera (for both C and ObjC backend) as well as adds a camera tutorial for both Android and iOS. What is missing is the API mapping from Android to iOS (xmlvm/src/android2iphone).

Hi Sander, One approach to this would be to first make sure this functionality is available when writing a Java to C program (non-Android) using XMLVM that covers the functionality you need. I am sure there will be work to get that part done. Once you are satisfied with that functionality, you can wrap it with the Android compatibility layer.

Hello list members, I'd like to use xmlvm for a project which, in an technical perspective, isn't overly complicated. The only non-trivial thing that it requires is working camera functionality. In Android there are 2 ways to handle "making a picture" as far as I can tell: 1) Use the result of an Intent 2) Set up your own camera view and handle everything yourself Both of them aren't working in xmlvm at the moment, but I've read in an older message on the mailing list that it isn't too hard to implement. So my question is, which one of the above would be the easiest to implement? I could also use some pointers on where to start with this. So far I understand that I have to implement the missing classes in src/android2iphone/android. But I'm sure that's not all... Thanks in advance! Best regards, Sander Knopper |

Guys,
as some of you know, we are working on generating the Java iOS API from
the original Objective-C header files. This would replace the
time-consuming, error prone process of doing this manually. Another
benefit is that we would have instant 100% coverage of the complete iOS API.
There is now a very first version of this new API to show where things
are headed. There are two new directories:
xmlvm/src/ios: contains the generated Java iOS API.
xmlvm/src/xmlvm2c/lib/wrapper: contains the generated C wrappers.
The new API lives in package org.xmlvm.ios.*. When cross-compiling an
iOS application with --target=iphonec, use the new command line
parameter --xmlvm-new-ios-api. At this stage, the new API only supports
structs (such as CGRect, CGPoint, etc). There is a minimalistic test
case in xmlvm/src/test/ios that can be cross-compiled in the following way:
java -Xmx1G -jar dist/xmlvm.jar --in=bin/org/xmlvm/test/ios/ \
--out=out --app-name=CGRectTest --target=iphonec \
--xmlvm-new-ios-api
To generate the new API yourself, you need to checkout trunk/crossmobile
in the same directory where you checked out trunk/xmlvm, then:
cd crossmobile
ant gen-xmlvm-ios
There is still much work ahead, but we wanted to give you a heads up on
the progress. Please consider to help if you have spare cycles.
Arno

I guess you're referring to src/org/crossmobile/source/guru/advisor.xml ?
Looking at what's already in that file, it seems like you're trying to
(a) avoid specifying anything for which the default choices are
already correct, and (b) keep the definitions general enough to make
it clear what the transformations are without having to understand how
the processor is implemented. So given that, I'd probably lean toward
something like this (and leave Reference<> to be the default):
<parametertypes>
<method signature="CGFontGetGlyphBBoxes::CGFontRefCGGlyph[]size_tCGRect[]">
<!-- or whatever the correctly mangled signature would be -->
<parameter index="1" type="List<CGGlyph>" />
<parameter index="3" type="List<CGRect>" />
</method>
</parametertypes>
However, taking another look through the skeleton, I'm starting to
think that maybe this is not the phase to be trying to Java-ize these
types of references. For instance, taking a look at
CGContext.addRects(Reference<CGRect> rects, int count), clearly in
Java this would be better translated as
CGContext.addRects(List<CGRect> rects) (the count parameter being
redundant). I'm thinking that rather than trying to convert from
Reference to List in the initial phase, it might be better to keep the
naive translation (Reference<>, int), and then later tack on a
written-by-hand convenience method like this:
public void addRects(List<CGRect> rects) {
addRects(Reference.fromList(rects), rects.size());
}
This type of approach of adding in convenience methods could also
perhaps be used to address some of the string conversion (String vs
byte[]) issues discussed previously.
Cheers,
--Aaron V.

Consider the example below. If we invoked the finalize() in the same
thread, it would deadlock & unfortunately can't be blamed on poor
application code since it's unrelated/unpredictable. If both threads are
attempting to "do stuff" at the same time, it would deadlock. That's one
reason the finalize() invocation occurs in a different thread, but if we
could do collection in that same finalizer thread, that would be nice.
Thread 1:
synchronized (obj1) {
synchronized (obj2) {
// do stuff
}
}
Thread 2:
synchronized (obj2) {
new Object(); // "new" causes a finalize() invocation on the
instance below
}
A different instance which is ready for finalization:
protected void finalize() {
synchronized (obj1) {
// do stuff
}
}
Thanks,
Paul

Thanks, my main point is about the necessity of the FinalizerThread more than the specific function used to bind the callback. I'll take a closer look at this. |
