Adobe Flash Professional CS5.5(AS3) with Distriqt Compass always says "The native extension context could not created"

I'm using Adobe Flash Professional CS5.5 with ANE Distriqt Compass, I've created a simple .fla project and written a few lines of AS3 script. The compilation was successful, but when I executed the .swf file on my PC, at the beginning it always says


"The native extension context could not be created"



I thought the problem is caused by my PC's lack of magnetometer, but when I packaged my code into a
.apk
file and installed it on my Android device, it said the same thing. After checking through the code, I found out that
Compass.init
never executes successfully.

Here is my project, can someone tell me what causes the problem?

I tried to...


  • Extract the file
    com.distriqt.Compass.ane
    as .zip file.

  • Then linked the file
    distriqt.extension.compass.default.swc


    under
    META-INF/ANE/default
    directory.



I also tried the solution from this link, but that doesn't work either. I've searched through the Google inside-out, but it seems to be have no solution.

That error indicates you aren't correctly packaging the ANE with your application.

With CS5.5 you'll need to package your application from the command line in order to correctly package ANEs. CS5.5 didn't include the ability to package applications using ANEs.

Firstly make sure you have added the extension ID to your application descriptor:

<extensions>
    <extension>com.distriqt.Compass</extension>
</extensions>

To add the extension:

  • Change the filename extension of the ANE file from .ane to .swc. This step is necessary so that Flash Professional can find the file
  • Select File > ActionScript Settings on your FLA file
  • Select the Library Path tab in the Advanced ActionScript 3.0 Settings dialog box
  • Select the Browse To SWC File button
  • Browse to the SWC file and select Open. The SWC file now appears in the Library Path tab in the Advanced ActionScript 3.0 Settings dialog box
  • With the SWC file selected, select the button Select Linkage Options For A Library (this looks like a small i in a circle above the panel).
  • In the Library Path Item Options dialog box, change the Link Type to External.

Next you’ll need to open up a command line in the directory of your built application. The directory should contain:

  • application swf: myApp.swf
  • application descriptor: myApp-app.xml
  • any required files such as icons, Default.png
  • the ANE(s) (in a subdirectory we’ll assume extensionsDir in the following)

The details on this command is dependent on the application you are developing and the platform you are targeting. You should review the documentation at the following url to determine the details of what the command should contain for your environment.

For example the following command will create an APK for Android:

adt -package
    -target apk
    -storetype pkcs12 -keystore YOUR_SIGNING_KEY.p12
    myApp.apk
    myApp-app.xml
    myApp.swf icons
    -extdir extensionsDir
