Problems creating a Native Extension linking to a static library
Hi,
I'm trying to create my own Native Extension for iOs that will use another static library.
My problem occurs when I try to package my app with ADT: after a lot of "ld warning: unexpected srelocation type 9" , I get a final error : "ld: thumb bl/blx out of range (-4468380 max is +/-4M)"
This may be caused by the fact that the static library I am using needs the gcc setting "compile for thumb" turned off. I've done that in XCode to get my .a file to generate my .ane, but how could I tell ADT to take it into account ?
Thank you for your help !
Are you compiling for ARMv6 or ARMv7?
With armv7, you do not need to switch off the "compile for thumb" anyways.
Also, I guess you are using an iOS version greater than 4.3 to compile your native library. In this case, using -platformsdk switch of adt, while packaging your application might just resolve your issue.(You will see some ld 4-byte alignment warnings, but thats ok)

Can someone tell me what I am doing wrong when creating a native extension for iPad? (Very detailed)
My company is developing a game for the iPhone and iPad devices using Flash cs5.5 and Air3.0
The client requires that certain features be supported - such things like GameCenter, Rating system, etc... none of which is currently supported by flash for the iOS.
However, they did provide us with a bunch of xCode sample files on how they want things to work.
My idea was to bridge the gap in functionality by creating a native exention that utilized the xcode source that was given to me, thus giving me the functionality that is required.
But first, I need to actually CREATE a native extension, even just a basic echo/hello world... I have followed all the steps from various guides and tutorials and I have managed to create an ipa and put it on my iPad2 to test, but when the program starts up, nothing happens, I am left with a black screen. When I comment out the lines of code that intialize the extension, it fires up just fine.
(and yes, I even tried to put things in try blocks in case there was an error - no luck)
So I am hoping that someone can read through the process of what I am doing below and point out what I am doing wrong, or what I am missing.
What I am using:
Mac Mini running OSX 10.7.2 - this is used to run xCode 4.1 build 4B110
PC - Windows 7 home 64bit - Running Flash CS5.5 (version 11.5.1.3469) with the AIR 3.0 SDK inside it. I also have the AIR 3.0 sdk in a seperate folder for command line running. (This is my primary developement platform)
The PC does have flash builder installed, but I have never really used it, nor do I know how to use it... everything that has been built to date has been done using Flash CS5.5
So, this is what I have done.
The first thing I do is create a .a static library on the mac.
I open xcode and create a new project.
Select iOS Framework and Library, then select "Cocoa touch Static Library"
Give it a name, in this case "EchoExtension" and put it in a folder.
I then delete the EchoExtension.h file as all the samples I have seen to date don't use it.
I then add "FlashRuntimeExtension.h" to the project from the AIR3.0 sdk frameworks folder on my PC
I then delete everything in my .m file and, following several different examples and tutorials, type up the following code:
// EchoExtension.m
// EchoExtension
#include "FlashRuntimeExtensions.h"
FREObject echo(FREContext ctx, void* funcData, uint32_t argc, FREObject argv[]) {
return argv[0];
//----------- Extention intializer and finalizer ----------------------------------------------------------------------------------------- ------------------------------------------------------------------------------------------ -
// A native context instance is created
void ContextInitializer(void* extData, const uint8_t* ctxType, FREContext ctx, uint32_t* numFunctionsToTest, const FRENamedFunction** functionsToSet) {
// setup the number of functions in this extention
// for easy reference, set the number of function that this extention will use.
int FunctionCount = 1;
// set the pointer reference to the number of function this extention will use.
*numFunctionsToTest = FunctionCount;
// create an array to store all the functions we will use.
FRENamedFunction* func = (FRENamedFunction*)malloc(sizeof(FRENamedFunction)*FunctionCount);
// create an array entry for each function
func[0].name = (const uint8_t*)"echo"; // the name of the function
func[0].functionData = NULL; // the data type
func[0].function = &echo; // reference to the actual function
// save the array in a pointer.
*functionsToSet = func;
// A native context instance is disposed
void ContextFinalizer(FREContext ctx) {
return;
// Initialization function of each extension
void ExtInitializer(void** extDataToSet, FREContextInitializer* ctxInitializerToSet, FREContextFinalizer* ctxFinalizerToSet) {
*extDataToSet = NULL;
*ctxInitializerToSet = &ContextInitializer;
*ctxFinalizerToSet = &ContextFinalizer;
// Called when extension is unloaded
void ExtFinalizer(void* extData) {
return;
I then go "Product", "Build" and it creates libEchoExtension.a
I copy this .a file over to my PC.
I am now finish with that god foresaken mac (*shudders*)
Back on my PC, I create a folder for my test project. For all intents an purposes, let's call this "D:\src\EchoExtension" I then create 2 folders, one called "lib" and one called "app". Lib is where I will create the actionscript source for my extension.
In my lib folder, I create a new fla in flash cs5.5 called "EchoExtension.fla"
I create in my lib folder, the following:
com\extensions\EchoExtension\EchoExtension.as
a folder called "Build" in which I place my libEchoExtension.a file.
in my EchoExtension.as file, I place the following code:
package com.extensions.EchoExtension
import flash.events.EventDispatcher;
import flash.events.IEventDispatcher;
import flash.external.ExtensionContext;
public class EchoExtension extends EventDispatcher
protected var _extensionContext:ExtensionContext;
* Constructor.
public function EchoExtension()
super();
// Initialize extension.
_extensionContext = ExtensionContext.createExtensionContext( "com.extensions.EchoExtension", "main" );
public function echo(Prompt:String):String
return _extensionContext.call( "echo" ) as String;
In my main fla, on the first layer of the time line, I simply put the following code to make sure that the as file get's included when I publish the swc.
import com.extensions.EchoExtension.EchoExtension;
var ext:EchoExtension = new EchoExtension();
stop();
I then open up my fla's publish settings, turn off the swf - which I don't need, and check the swc and make sure that it outputs into my build folder. "./Build/EchoExtension.swc"
I also set the player to Air 3.0 (which I can do since I have successfully integrated AIR 3.0 along side my AIR 2.6 and can build both without any problems)
I then publish the swc. So far, so good. No problems.
I then make a copy of the swc and rename it to EchoExtension.swc.zip, at which point I extract the library.swf file from it and also place it in my build folder.
I then create extension.xml in by build folder which contains the following code:
<extension xmlns="http://ns.adobe.com/air/extension/2.5">
<id>com.extensions.EchoExtension</id>
<versionNumber>1</versionNumber>
<platforms>
<platform name="iPhone-ARM">
<applicationDeployment>
<nativeLibrary>libEchoExtension.a</nativeLibrary>
<initializer>ExtInitializer</initializer>
<finalizer>ExtFinalizer</finalizer>
</applicationDeployment>
</platform>
</platforms>
</extension>
Now, at this point I am a little wary, because I am building for the iPad2... the platform is iPhone... I thought that may be a problem and at one point I tested the same build on the iPhone4 and had the same results. I have also tested it using the platform name of iPad-ARM and got the same results... So I don't think that is the problem, but I am unsure.
Now, to make things easier, I created a batch file called "buildane.bat" in my build folder. This is what I will use to create my .ane file and it contains the following command line:
D:\SDKs\AirSDK30\bin\adt -package -target ane EchoExtension.ane extension.xml -swc EchoExtension.swc -platform iPhone-ARM library.swf libEchoExtension.a
I then open a command prompt and run buildane.bat and poof. My ane is created. My build folder has the following files in it now:
buildane.bat
EchoExtension.ane
EchoExtension.swc
EchoExtension.swc.zip
extension.xml
libEchoExtension.a
library.swf
Now that I have my swc, ane, and all that, it's time to create my sample application that will be used to test my new extension.
I go back to my D:\src\EchoExtension folder and go into the app folder I created ealier.
I then create a new flash project called EchoExtensionTester.fla
I open the action script settings, library paths, and add the swc that I created in my D:\src\EchoExtension\lib\build folder to my project.
On my stage, I create an input text field called txtInput, a dynamic text field called txtEcho, and a couple of buttons called btnClear, btnRuntime, and btnEcho
I open up the first layer in the time line and place the following code:
// basic imports.
import flash.desktop.NativeApplication;
import flash.events.MouseEvent;
import flash.text.TextField;
// import the extension from our swc.
import com.extensions.EchoExtension.EchoExtension;
// set our input text field to need the softkeyboard
txtInput.needsSoftKeyboard = true;
// add the event handlers to our buttons.
btnEcho.addEventListener(MouseEvent.CLICK, btnEcho_Click);
btnClear.addEventListener(MouseEvent.CLICK, btnClear_Click);
btnRunTime.addEventListener(MouseEvent.CLICK, btnRunTime_Click);
// create our extension variable.
var ext:EchoExtension;
try
// initialize our echo extension.
ext = new EchoExtension();
} catch (e:Error) {
txtEcho.text = "Error trying to create new EchoExtension:\n\n" + e;
stop();
// clear the echo text field
function btnClear_Click(e:MouseEvent):void
txtEcho.text = "";
// just for testing, put the current version of air runtime into our text field so we can make sure we are running air 3.0
function btnRunTime_Click(e:MouseEvent):void
txtEcho.text += "\nRuntime version = " + NativeApplication.nativeApplication.runtimeVersion;
// call the extension, passing it whatever is in the input text field and have it return it and place it in our echo text field
function btnEcho_Click(e:MouseEvent):void
txtEcho.text += "\n";
try
txtEcho.text += ext.echo(txtInput.text);
} catch (e:Error) {
txtEcho.text += "\nError calling ext.echo: " + e;
I then save the project, Open the Air for iOS settings and set the following: (but yes, I know... I am going to have to use adt to do the build, but I need to create the swf first)
Output file: EchoExtensionTester.ipa
Appname: EchoExtensionTester
Version 1.0
Landscape
Fullscreen On
Auto orientation is off
rendering GPU
device: iPad and iPhone
Res: High
Deployement: I use my certificate and provisionging profile that I use for my Primary project (which work) and set for device testing.
I close the window and save again... but before I publish, I open newly created "EchoExtensionTester-app.xml" that is in my app folder.
I add <extensions> <extensionID>com.extensions.EchoExtension</extensionID> </extensions> to the xml file so now it looks like this:
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<application xmlns="http://ns.adobe.com/air/application/3.0">

I save the changes to the xml and go back to flash. I then publish.
The swf is created as it should be, but then I get the error message:
Error creating files.
An implmentation for native extension 'com.extensions.EchoExtension' required by the application was not found for the target platform.
Now, while this is a pain in the rear, I new this was going to happen because in my reading of tutorials and samples, they all said that you must use adt to build the ipa... but that's fine... all I wanted anyway was the swf, which I now have in my app folder.
I close down flash as I don't need it anymore and I create a new batch file: (note: I change the names of the cert, provision profile, and password for this post)
cls
"D:\SDKs\AirSDK30\bin\adt" -package -target ipa-ad-hoc -storetype pkcs12 -keystore "D:\src\mycert.p12" -storepass MYPASSWORD -provisioning-profile "D:\src\myprovfile.mobileprovision" "EchoExtensionTester.ipa" "EchoExtensionTester-app.xml" "EchoExtensionTester.swf" -extdir ../lib/Build
set /p dummy=
echo done
I then open a command window in my app folder and run build.bat...
I wait about 2 minutes....
YAY! My ipa file has been created with no errors reported so far.... Time to copy this bad boy to the iPad and see what happens.
I open iTunes, drag "EchoExtensionTester.ipa" over to the Apps, then sync my device....
YAY! iTunes has successfully installed the ipa on the device... and there is by bright and shiney blank icon for Echo Extension Tester...
I open the app.... and.....
nothing.
I wait
still nothing.
I go to the bathroom.
I get back... still nothing... just a black screen.
I press the iPad home button, the app minimized, I restore it... nothing... black screen.
hrm. Time to do a little trial and error to see if I can figure out where the break down is.
As a test, I open my fla and I comment out the following lines:
ext = new EchoExtension();
txtEcho.text += ext.echo(txtInput.text);
I then rebuild the swf... get the same error (don't care)... I then rebuild the ipa using the batch file.... and re-install it on the device when it's done.
The exact same thing....
I open the xml file... and remove the <extensionID>com.extensions.EchoExtension</extensionID> line, save and re-run the batch file again... wait for the ipa to finish, and run it on the device.
I fire up the program on the iPad and it launches perfectly... except for the commented line of code to actually create and call the extension, everything works as it should. The runtime on the device is reporting as 3.0.0.4080
As a test, I open the .fla back up and uncomment the 2 lines I commented out above... keeping the extensionID out of the xml file, I re-publish the ipa.... of course, this time, it actually creates the ipa from flash because the extension id is not in the xml.
I put the ipa file with the extension code in place on the ipad... Fire it up and put some text into the txtInput and press the echo button. I get the following error:Error calling ext.echo: TypeError: Error #1009
I suspect that is because I failed into include the extension in the descriptor... but when I build it with the extensionid in the xml, I just get a black screen. I am 99% sure that the extension context in the ext object is null (because that is what happens when I run it in flash debug without the extension lines in the xml)
And here I am stuck.
Can anyone tell me what I am doing wrong or what I have forgotten to do?
Thanks.I have been trying to get the remote debugging working with my flash and ipad2... but I can't seem to figure it out. I looked at several tutorials, but the ipad build just doesn't want to seem to connect to the flash remote debugger.
Anyway... here is a little more information.
I moved the initialization of the extension from the start of the application to the button event itself. Now, the application will start up exactly as it's supposed to, but when I press the button that creates and initalizes the extension and does the echo call, the application crashes.
Here is the new code:
// basic imports.
import flash.desktop.NativeApplication;
import flash.events.MouseEvent;
import flash.text.TextField;
// import the extension from our swc.
import com.extensions.EchoExtension.EchoExtension;
// set our input text field to need the softkeyboard
txtInput.needsSoftKeyboard = true;
// add the event handlers to our buttons.
btnEcho.addEventListener(MouseEvent.CLICK, btnEcho_Click);
btnClear.addEventListener(MouseEvent.CLICK, btnClear_Click);
btnRunTime.addEventListener(MouseEvent.CLICK, btnRunTime_Click);
txtEcho.text += "Initialization complete.\n";
stop();
// clear the echo text field
function btnClear_Click(e:MouseEvent):void
txtEcho.text = "";
// just for testing, put the current version of air runtime into our text field so we can make sure we are running air 3.0
function btnRunTime_Click(e:MouseEvent):void
txtEcho.text += "Runtime version = " + NativeApplication.nativeApplication.runtimeVersion +"\n" ;
// call the extension, passing it whatever is in the input text field and have it return it and place it in our echo text field
function btnEcho_Click(e:MouseEvent):void
// create our extension variable.
try
var ext:EchoExtension = new EchoExtension();
txtEcho.text += ext.echo(txtInput.text) +"\n" ;
ext = null;
} catch (err:Error) {
txtEcho.text += "Error: " + err.message +"\n" ;
Now, program crashes are an entirely different animal because the ipad creates a crash log! YAY!
this is what the crash log contains:

Problem creating several image maps (linking to different pdf files) RoboHelp 8
Hi,
I have a problem creating several image map hotspots (that link to different .pdf files), from the same image using RoboHelp 8 HTML (WebHelp project).
After compiling, the first image map hotspot created, opens the .pdf file correctly. Unfortunately, when clicking on the other image hotspots, I get an error " Cannot find file...<file path>... Make sure path or Internet address is correct".
All the pdf documents are located in the same folder within the project.
Can anyone help?Have you added the target files as baggage?

Problem creating native extension package
In an effort to learn how to create a native extension on my own, I've looked to the examples and help documentation from Adobe. I have actually created the required files for the extension (the native code, extension descriptor, the swc library and library.swf). However, when I run the command to build the .ane file I get this error:
/Users/dalston/TeamAGC/sdk/4.6.0/bin/adt -package -target ane ../release/DeviceInfoExtension.ane extension.xml -swc DeviceInfoExtension.swc -platform iPhone-ARM library.swf libDeviceInfo.a
output file is not writable
I also tried a variation of that command that results in the same error (which comes straight from the Adobe help docs):
/Users/dalston/TeamAGC/sdk/4.6.0/bin/adt -package -target ane ../release/DeviceInfoExtension.ane extension.xml -swc DeviceInfoExtension.swc -platform iPhone-ARM -C platform/ios . -platform default -C platform/default library.swf
output file is not writable
I'm not sure what I'm doing wrong here. Has anyone had this problem before? Thanks in advance for your help!Hello Colin,
The folder I was working from /Users/dalston/TeamAGC/sdk/4.6.0, which is where the AIR sdk resides. The actual directory with the native extension files are in /Users/dalston/Documents/Adobe Flash Builder 4.6/DeviceInfoExtension/bin/DeviceInfoExtension. When I run the ls command I see all the folders under the main user (dalston, which is me). I believe I have read/write access to everything since I am the adminsitrator on this machine. I am on a Mac by the way. -
Create Native Extensions around pre-existing dll
Is it possible to create a native extension around a pre-existing DLL without writing any native code? Or do I have to write a slim wrapper around my dll in order to interface with AS3?
anybody?

Unable To Build iOS App Using Native Extension
I’m trying to create a native extension for iOS and use that extension as part of an IPA app for iOS I create from a SWF file using the ADT tool (i.e. the normal use-case for iOS). Note: I have already successfully created the native extension and APK app for Android and now I am trying to build the iOS side.
I have been primarily using the information found at the following websites:
http://www.adobe.com/devnet/air/articles/building-ane-ios-android-pt3.html

http://help.adobe.com/en_US/air/build/WS901d38e593cd1bac35eb7b4e12cddc5fbbb-8000.html
I have also searched the Adobe forums for the answer to my question without success.
The error I receive is:
ld: warning: ignoring file /var/folders/c3/mpg4frwn2j1f8scw4jctbmv9hfkswj/T/bd3fbd4a-cf56-4fd6-a06d-d69ea92dc620/lib com.mycompany.MyExtension.a, file was built for archive which is not the architecture being linked (armv7): /var/folders/c3/mpg4frwn2j1f8scw4jctbmv9hfkswj/T/bd3fbd4a-cf56-4fd6-a06d-d69ea92dc620/lib com.mycompany.MyExtension.a

I am using XCode to build MyExtensionIOSLibrary.m into a library file with a .a filename extension. My relevant build settings are:
iOS Deployment Target: iOS 5.1
Architectures: armv7
Build Active Architectures Only: No
Product Scheme: Release
Compile Sources As: Objective-C
Any ideas? Please help.Thanks for the reply.
yes.I've created a static library with 3rd party frameworks and pulled the .a from product folder(Debug-iphoneos).
and the framework didn't work(armv7 not supported error occurs ..don't know why) with it's original folder structure .
so I followed below link to change folders inside the 3rd party framework and figured out but now the application crashes on startup without giving an error message. .

Air Native Extension - Java Key Listener
Hello all,
Firstly I'd like to thank you for creating an excellent and helpful community. I have an issue I have been stuck on for around 2 weeks now.
I am creating an android native extension to listen to key input from a proprietary remote control device. GameInput does not recognise it as a game controller so we have to create a native extension to get the input. I have it working fully except for one issue; if the game loses context (eg the user gets a phone call or the game goes into the background for any other reason) I do not get any other input.
The way I am doing it is to attach an onKeyListener to the currently focused View (an AirWindowSurfaceView). This works perfectly, but when the context is lost I'm assuming the AirWindowSurfaceView changes and I cannot find a way to get a reference to the new one. Here is my key listener setup code (from the native Java):
public void updateListeners()
if(_view != null)
_view.setOnKeyListener(null); //remove from the old view
_view.setOnGenericMotionListener(null);
_context.dispatchStatusEventAsync(_view.toString(), "view"); //send the current view details
_view = _context.getActivity().getCurrentFocus(); //set the new view
_context.dispatchStatusEventAsync(_view.toString(), "view");
if(_onKeyListener == null)
_onKeyListener = new NativeGamepadKeyListener(_context, this); //create new key listener
if(_onGenericMotionListener == null)
_onGenericMotionListener = new NativeGamepadMotionListener(_context, this); //create a new motion listener
_view.setOnKeyListener(_onKeyListener); //set on the new view
_view.setOnGenericMotionListener(_onGenericMotionListener);
This updateListeners function is called when I get a focus change event on the current view (attached in a similar way) but this doesn't seem to keep it up to date with the current View.
Please note I'm a newbie at making extensions like these and might be going about it totally the wrong way - if I am and you have any suggestions as to the best way to use an onKeyListener in a native extension I'd love to hear it.
Thanks in advance for your help!I am not able to solve this yet. Is anybody else facing this this problem.

64bit AIR Native Extension for iOS
Hello,
I created a native extension to support ARM64 for iOS. The problem is I get the following error when packaging an ad-hoc build:
"Error: libgameCenter.a are required to have universal iOS libraries. Please contact the ANE developer(s) to get the same."
As I understand I need both armv7 and arm64 libraries. So I build for both of them using "xcodebuild" and then merge with "lipo -create" command.
However I think there is a step I'm missing. Please advice. Thank you.
AIR SDK: 16.0 beta
Xcode: 6.1.1Well the change you need to do is inside your Xcode project, under Build Settings -> Architectures , make sure that you have selected "Standard Architectures (armv7, arm64)". One last thing to ensure that Valid Architectures should also contain arm64 entry along with other armv7 entries.

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. -
Facing error#3500 while running AIR native extension for windows
Hi,
I am stuck in a problem regarding AIR native extension from couple of days.Whenever I tried to run an extension for windows it gives error code 3500 (extension context cannot have the method ie methodname).I am doing all things correctly but don't know where I lack.I am using Flash Builder 4.6 and 64 bit machine.I made the sample extension POC for android ,they are working fine.No such issue.
Please post your valuable comments.Eagerly waiting for reply.
ThanksHi,
Finally I got the answer to my problem.Actually I dont have the dependency dll of .net framework 4.So I nstall these and now my code is working fine.
Thanks -
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! -
