Hi all :-)

I am an android expert and I'd really love to create some cool extensions like the android notifications, but since I don't know much about Flex, I have a lot of trouble getting the test vibrator with native extension working.

(http://www.adobe.com/devnet/air/native-extensions-for-air/extensions/v ibration.html)

My sample is still buggy, it is probably beginner's bug, but I don't see how to fix it yet.

I am surely not the only native guy trying to do this, so I would like to sumarize here all the steps needed to have our first hello world Native Extension API

1. Install Flex 4.5.1 http://www.adobe.com/go/try_flashbuilder/ and download the Adobe AIR 3.0 RC http://labs.adobe.com/downloads/air3.html  as well as the sample files http://download.macromedia.com/pub/developer/air/ane/Vibration.zip
2. Create a test Flex mobile project.(all the deffault parameters are fine) I'll call it HelloWorldNativeExtension.
3. (If AIR 3 is not released yet) Do the following to tell Flex builder to use the RC on your test project : http://forums.adobe.com/thread/899921
4. Unzip the vibration.zip, and go to ready to use extansion.
5. Go to Project -> Flex buildpath -> Libraries -> Add a new swc. Add the ready to use extension as a library. Then open the extensions properties and change the link type from "bundled with" to "external linkage"
6. Go to HelloworldNativeExtension-app.xml and in the tag manifestAddition, add : <uses-permission android:name="android.permission.VIBRATE"/>
7. Write a sample view (as described below)
8. Run (target platform->android and then chosse to run on a device)
9. When asked to update the air version, answer yes
10. Wait a loooong time before it actually start.

Here is my code for the sample view:

In HelloworldNativeExtension.mxml

Use the following code :

<?xml version="1.0" encoding="utf-8"?>

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

               xmlns:s="library://ns.adobe.com/flex/spark"

               xmlns:mx="library://ns.adobe.com/flex/mx">

    <fx:Script>

        <![CDATA[

            import com.adobe.nativeExtensions.Vibration;

            protected function testButton():void

            {

                textArea.text="Before vibration";

                var vibe:Vibration;

                if (Vibration.isSupported)

                {

                    vibe = new Vibration();

                    vibe.vibrate(2000);

                }

                textArea.text="After vibration";

            }

        ]]>

    </fx:Script>

    <s:Panel title="Exemple MXML" width="330">

        <s:layout>

            <s:VerticalLayout paddingLeft="15" paddingTop="15" paddingBottom="15" paddingRight="15"/>

        </s:layout>

        <s:Label x="223" y="173" text="test" id="textArea"/>

        <s:Button label="Vibrate" click="testButton()"/>

        <s:Label id="result" width="265"/>

    </s:Panel>

</s:Application>

Well... so far my project doesn't compile because the library is loaded externally. It compiles fine if I add it as a bundled library, but then the virbrator can't work (External native code have to be loaded externally)

And thus so far I get the errors :

(Which means something like : 1046: this type cannot be resolved or is not in the buildpath ... So it probably means the project doesn't compile well)

So I'm still trying to figure out what to do, but I am close I think... Very close.
