IOS Native Extension with external Framework

Hi there,
I am developing a native extension for iOS based CityGrid framework. I compiled .a file and packaged it to ANE file. However when I am trying to compile the app, compiler shows me the error:
Error occurred while packaging the application:
Undefined symbols:
"_OBJC_CLASS_$_CityGrid", referenced from:
__objc_classrefs__DATA@0 in libcom.example.SomeAPI.a(SomeAPI.o)
ld: symbol(s) not found
Compilation failed while executing : ld64
I tried few options in XCode. However I still have the error.
Is anybody tried to do a native extension with external frameworks?

How did you compile your ane file? I met same issue before.
adt -package -target ane myextension.ane extension.xml -swc mySwc.swc -platform iPhone-ARM library.swf libmylib.a -platformoptions myplatformoptions.xml
lnside myplatformoptions.xml, I linked all the framework and shared libraries, as following
<platform xmlns="http://ns.adobe.com/air/extension/3.1">
     <sdkVersion>5.1</sdkVersion>
     <linkerOptions>
          
          <option>-framework CoreMotion<option>
          
          <option>-liconv</option>
     </linkerOptions>
</platform>
Please let me know, if it does work.

Creating ios native extension with 3rd party frameworks

Сertificate exception when building iOS native extension

I have certificates for developer and distribution . I signed AIR apps using those certificates, and all work (I publiched 5 games to AppStore, all OK).
But when I try to compile an iOS native extension, I get:

Flash Pro CS6 iOS Native Extension Problem

I am trying out flash pro CS6 new features.
The most important one being ANEs [native extensions].
in flash builder 4.6, when using an ANE for ios, it is sometimes required to put the ios5 SDK location [ -platformsdk in ADT].
This is completely missing in Flash Pro CS6 IDE, any way around that?
[for the info on including the ios5 sdk check:
http://help.adobe.com/en_US/flex/mobileapps/WSe4e4b720da9dedb5-4aefe03513238d8a1b8-8000.ht ml]
Thanks.

Uhmm, i'm doing a kind-of-360º-panorama-app and we need Gyroscope and Ad-hoc / AppStore distribution. And i've tried to get an answer of any kind from guys on Adobe on their AIR facebook fan page and here.
SHould we write our own gyroscope ANE?, have any of you succesfully compiled ad-hoc or app-store with Ketzler Euler Gyroscope ANE?

Please give me your comments

First of all, thank you for creating this extension. However, it doesn't seem to work. Below is my code for decompressing ByteArray (error handling is stripped for simplicity):
                    public function decompress(aData:ByteArray):ByteArray {
                              // Save data to file
                              var fileInput:File = File.applicationStorageDirectory.resolvePath("input.7z");
                              var stream:FileStream = new FileStream();
                              stream.open(fileInput, FileMode.WRITE);
                              stream.writeBytes(aData);
                              stream.close();
                              var folderOutput:File = File.applicationStorageDirectory.resolvePath("output");
                              ANE7z.decompress(fileInput, folderOutput);
                              var files:Array = folderOutput.getDirectoryListing();
                              for each (var fileOutput:File in files) {
                                        trace("Extracted file: " + fileOutput.nativePath);
                                        if (!fileOutput.isDirectory) {
                                                  var bytes:ByteArray = new ByteArray();
                                                  stream = new FileStream();
                                                  stream.open(fileOutput, FileMode.READ);
                                                  stream.readBytes(bytes);
                                                  stream.close();
                                                  bytes.position = 0;
                                                  return bytes;
                              return null;
The problem is folderOutput.getDirectoryListing() always returns an empty array.

Duplicate symbol in iOS native extension

I'm trying to add an Objective C class to an existing native extension that I have for iOS. The code builds fine in Xcode, and the ANE process still seems to work fine. But when I try to package the application for debugging on my iPhone I get this error:
Error occurred while packaging the application:
ld: duplicate symbol _OBJC_METACLASS_$_EmailViewDelegate in C:\Users\jmiller\AppData\Local\Temp\18faba99-de69-437b-8fed-c983e5ce2882/libTspNativeExt. a(EmailViewDelegate.o) and C:\Users\jmiller\AppData\Local\Temp\18faba99-de69-437b-8fed-c983e5ce2882/libnet.theservic epro.a(EmailViewDelegate.o) for architecture armv7
Compilation failed while executing : ld64
EmailViewDelegate is the name of the class I'm trying to add. libTspNativeExt.a is the library I'm building in Xcode. I have no idea where libnet.theservicepro.a is coming from but it is based on the id from my extension.xml (which is net.theservicepro). I've inspected the ANE with WinRAR and although I see my libTspNativeExt.a in the iOS folder, I do not see this other library anywhere.
The only fix I'm seeing is to use hideAneLibSymbols=yes in the launch parameters. However, when I do that I get this error while packaging:
Error occurred while packaging the application:
Compilation failed while executing : ld64
Most people are running into this problem with two native extensions that actually conflict. But something in my flow seems to be duplicating the code within my single ANE. Any suggestions?

And all it took was typing out the question for the answer to hit me. I'm going to share it here incase anyone else runs into this same problem.
The problem was in my platform_options.xml file for iOS. The previous coder had set it up like this:
<packagedDependencies>
<packagedDependency>libTspNativeExt.a</packagedDependency>
<packagedDependency>BMSPrinterKit_US.framework</packagedDependency>
</packagedDependencies>
So behind the scenes, ADT is putting all these dependancies into a libextensionid.a library which means we were telling it to import our library a second time. I'm amazed it actually worked before!

IOS native extension for networkinfo throws an error

Hello,
I'm trying to check wether the active connection on a device is Wifi or mobile data connection. On android this works fine but on iOS there is a problem.
A native extension exists for this see here.
The problem is that the line below throws an error: 'Error #1009: Cannot access a property or method of a null object reference.'
var interfaces:Vector.<com.adobe.nativeExtensions.Networkinfo.NetworkInterface> = com.adobe.nativeExtensions.Networkinfo.NetworkInfo.networkInfo.findInterfaces();
I'm using AIR3.1 (no idea if this works on 3.0).
Anybody a solution?

Ever solve this? I'm also getting errors...
Specifically:
ArgumentError: Error #3500: The extension context does not have a method with the name getInterfaces.

Successfully using a Native Extension with Flash CS5.5 Pro, having issues

Hey all,
I'm trying to use a native extension due to an app rejection about the new storage guidelines. I'm hoping someone can help me figure out how to use a native extension from Flash CS5.5 and the adt command line utility (I've never used before).
Apples storage guidelines in 5.0.1 require files saved to Documents (and other places) to be marked with the icloud "do not back up" bit. I'm trying to use Adobe's IOS 5.0.1 data storage native extension to do that as I have file sharing enabled and my app downloads files I want the user to be able to copy to their desktop.
From the bits and fragments I'm reading all over, getting it to compile means using the command line adt tool (I've never used it before) because Flash Pro CS5.5 doesn't support native extensions. Also, this native extension requires a v14 SWF published (11.1) and CS5.5 only goes up to 10.2 (or higher if you install the players).
I edited the AiriPhone.xml file and pointed it to an AIR 3.1 airglobal.swc and I have AIR 3.1 overlayed in flash. I can't test AIR for iOS anymore after that change but I can get it to compile a SWF. The adt command line adt utility stopped complaining that my SWF version was 13 when it needed 14, so I assume this worked?
I am trying to compile a debug version so I can see trace statements to see if the native extension reports success on changing the bit. Here is my command line cobbled together from scraps of info on adobe.com and the -help data:
adt -package -target ipa-debug -connect 192.168.1.80 -provisioning-profile myApp.mobileprovision -storetype pkcs12 -keystore myApp.p12 myApp.ipa myApp-app.xml myApp.swf dat AppIconsForPublish Default-Landscape.png Default-LandscapeRight.png -extdir extensionDir
Before this iCloud change this app published directly from Flash Pro CS5.5 without any issues. I am only running into issues getting this app to work with this native extension and/or published correctly.
I am including the folders "dat" and "AppIconsForPublish" as well as splash screens (this app is landscape-only) as well as that extension in the folder extensionDir.
After putting in my password my app compiles into an IPA which I can drop into iTunes. It has the same general size as the IPA generated from Flash Pro. The icon is correct, etc.
When I sync this file, the progress bar goes across, I see it loading on my iPad and then once it goes to install I get a popup saying "iTunes Sync: 'myApp' failed to install."
Is there anything obvious wrong with my adt line? Has anyone else used this native extension? Ideas on what I can do to fix this?
No, unfortunately I did not build this with Flash Builder. I am an avid user of it now and this would be a moot point as it uses ANEs and changes SWF versions trivially. I have to get this to compile using Flash Pro CS5.5 though.
Any help is greatly appreciated!
edit:
Just FWIW, after I updated the .xml to use the latest AIR and such (so the version is 14) I removed the extension, exported purely from Flash Pro CS5.5 and the app works fine. As soon as I enable the <extension> in the XML I can no longer install the app. This just appears to be a noob adt publish issue.

My app downloads PDFs, movies and other information-esque files and saves them to the apps Documents folder so they can be retrieved via file sharing. These files not being in something purgable like /Library/Caches and not having the "do not back up" bit is why I was rejected.
update: It's definitely my command line building.. I took out the native extension completely and published from flash to an IPA and it works. I then run adt on the same SWF that just worked and it fails to install. So the install failing is my command line. I see this article and my command line is very similar. I'm really uncertain why it's failing.

Publishing air apps with native extension with Flash CS6 on Windows

Hi all,
is there any trick to publish air apps with Flash CS6 on Windows?
I tried all native extensions from devnet, but nothing work to me.
I read on Mac is possibility to specify the iOS SDK folder in publish
settings, but on Windows it´s missing.
Is there anybody who has some experiences with publishing apps
with native extensions for iOS and Android with windows Flash CS6?
Thanks for all advices.

I sympathize. I recently found a native alert for iOS and Android that's working with Flash CS6 on Windows with AIR 3.2.0.2070 but not AIR 3.2.0.2060. You can get the ANE here:
http://www.jampot.ie/ane/
Haven't tried the other ones. Let us know if you decide to try them.
The sample code they have on the page doesn't work with the native alert. Here's the code I created - it's a document class for a .fla that has one dynamic TextField and one Button component on the stage :

AIR3 (iOS) - Native Extension (objectiveC) - control Acrobat PDF API

In my iPad app, I want to load in a PDF and then get control of the Acrobat API to allow the user to interact with the PDF as they see fit.
Is this possible?
I am making the assumption that there is currently objectiveC code available to use the Acrobat API on the iOS. Can anyone verify?
I am also making the assumption that through Native Extension I can bridge to this objevtiveC code from AS3 on the iOS. Can anyone please verify?
Thanks...

Yes. The ability to word search and jump to a specific page.
Bringing up a PDF in iOS browser or through StageWebView you cannot perform these actions.
I've seen iPad apps that can word search and page jump. I'm assuming this is being done with ObjectiveC.
I'm looking for someone to confirm this is the case.
Because if so I'm hoping we can then code a Native Extension utilizing this ObjectiveC code and thus control the PDF the way we want.

Native extensions with AIR 3.3

Did someone successfully compile with ADT native extensions like com.adobe.Vibration with AIR 3.3 ?
Thank you !
(Since i've moved to 3.3, it doesn't work anymore)

Hi,

stage.scaleMode = StageScaleMode.NO_SCALE;
var myTimer:Timer = new Timer(2000, 1);
myTimer.addEventListener(TimerEvent.TIMER, timerHandler);
myTimer.start();
subsButton.x = 150;
subsButton.y=10;
subsButton.addEventListener(MouseEvent.CLICK,subsButtonHandler);
stage.addChild(subsButton);

var vibe:Vibration;
if (Vibration.isSupported)
trace("1");
trace("12");vibe = new Vibration();
trace("13");vibe.vibrate(2000);
trace("14");
trace("15");
I am using the ANE and SWC provided at
http://download.macromedia.com/pub/developer/air/ane/Vibration.zip and I am using the target ipa-ad-hoc on device iphone4 .
Can you please specify if you are doing something else in your app?It would be great if you can send your sample app with the steps to reproduce @ [email protected] ,so that we can reproduce the issue .
Thanks,

Multiple IOS Native Extension

Hi everyone,
ok, I'm trying to compile an IOS application in AIR and I have to use 2 differents native extension.
I use ANT to execute the ADT command line but I got an error message that don't seems to happen to anyone!
The console simply says : Conflict in filename : unpack/catalog.xml
I specify the -extdir twice because I use subfolder for each NativeExtension.
ANT look like this:
<target name="ipa">
                    <exec executable="${sdk.air}/bin/adt" failonerror="true">
            <arg value="-package"/>
            <arg value="-target"/>
            <arg value="ipa-debug-interpreter"/>
            <arg value="-provisioning-profile"/>
            <arg value="${provision.wildcard}"/>
            <arg value="-storetype"/>
            <arg value="pkcs12"/>
            <arg value="-keystore"/>
            <arg value="${keystore.file}"/>
            <arg value="-storepass"/>
            <arg value="${keystore.password}"/>
            <arg value="../${project.name}.ipa"/>
            <arg value="${project.name}-app.xml"/>
            <arg value="-extdir"/>
            <arg value="${extension.camera}"/>
            <arg value="-extdir"/>
            <arg value="${extension.p2p}"/>
            <arg value="${project.name}.swf"/>
            <arg value="-platformsdk"/>
            <arg value="${sdk.ios}"/>
        </exec>
    </target>
I think that it's because ADT unzip and move some stuff in the same directory. Does someone have a clue for me ?
Thanks!

Hi Yannick,
Both the ANEs contain a file named catalog.xml. Sice resources are copied to the top level of the final IPA bundle the second catalog.xml to be copied there causes the problem. If both the ANEs depend on this file and expect the contents of the file to be different then removing one would lead to runtime errors. However, if you know that the contents of catalog.xml are the same in both ANEs or that the code does not depend on this file being present (included by mistake?), you can remove the file from one of the ANEs. Just unzip the ANE, remove the file and create the package using adt again.

IOS Native Extensions [ANEs] + Classic Textfield weird bug

I tried flash CS6 and Flash builder 4.6
I am building an iPad app where I have a classinc input textfield.
The iOS behavior is normal when the user taps on the field, the keyboard is shown, the application moves up to show the field, and when the user clicks on the stage or on "DONE" the keyboard is removed
and the full app is moved back to position.
But, Whenever I add an ANE, and I set the iOS5 SDK location [needed by most ANEs], then publish, the behavior changes:
- When the keyboard needs to disapear, the application does not move back to position!
The behavior is fine with ANEs that do not need the iOS5 Location.
I was planning on releasing the app today as it is all done.

I filed it as a bug
http://bugs.adobe.com/jira/browse/SDK-32184

Application with native extension crashes onstart

I've created a flex mobile project with ios native extension(with ad frameworks such as facebook,chartboost ) and linked 3rd party frameworks.
when I start the application,it's crashes.I can't see any logs.is this a problem with linking 3rd party frameworks?
framework didn't work properly with it's directory structure so I followed below link. copied header files .a file to the top of the directory in the 3rd party framework and
removed other folders.

please help

I've been trying to make a Chartboost ANE as well, and I have the same problems as you.
First of all, it's easier to just use the headers and Chartboost static library directly in the Xcode project, instead of the Chartboost.framework. This way, your own .a file will include the Chartboost library, and you don't need to package it in the ANE. The resulting ANE will be smaller as well.
But whichever way you do it, the app will still crash. The error I get is the following:
<Error>: -[__NSCFString isEqualToNumber:]: unrecognized selector sent to instance 0x17802a4e0
This seems to be a problem with newer versions of the Chartboost SDK specifically. So for now I'm still using Chartboost 4.0 in my ANE. Unfortunately it doesn't contain some of the new features I'd like to use.
I've contacted Chartboost support about it. But they say they don't support AIR, and their SDK is working fine when used in a regular native app.
So somehow the combination of Chartboost and AIR is making it crash... If anyone has been able to get it working with the new Chartboost SDK, I would sure like to hear about it!

How to use single ant build script to package the application with and without native extensions

Hi,
I am using iOS native extensions for Adobe air. For this I am listing the extensions in the application descriptor file. Since the package with native extensions are meant to run only on device, I want my build script to work without native extensions too to be able to run on simulator. Is this manadatory that I need two separate application descriptors/basically two build scripts to compile and package them? Please suggest and let me know if more explanation is needed.
Thanks,

Hi
This is a known issue addressed by CR205204
As you said, IBM actually does not have rt.jar in its JDK - they have moved contents of rt.jar into various jars.
IBM is not using org/apache/crimson/tree/ in their JDK at all.So the error shows up in the end of build even if it succeeds
You may need to add crimson.jar to wlwBuild classpath, since it is not part of IBMs JDK.
Note: the build will work even w/o crimson.jar giving a non build related IDE exception in the very end.
Thanks
