"application descriptor not found" when trying to create .ane file

Question

I have been trying to create a very simple native extention for the better part of a week now and I just can't seem to figure it out.
Using tutorials and guides from the following sources:
http://www.adobe.com/devnet/air/articles/extending-air.html
http://www.adobe.com/content/dam/Adobe/en/devnet/devices/pdfs/DevelopingActionScriptExtens ionsForAdobeAIR.pdf
http://custardbelly.com/blog/2011/09/21/air-native-extension-example-ibattery-for-ios/
I managed to get up to the point where I need to create the ane file, but I am getting "application descriptor not found".
So, here is the detailed explanation of everything I have done to date. Can someone tell me where I have gone wrong?
1. On the mac, I created an xcode project, using the iBattery example code from the link above, I managed to create static library .a file. I am not going to discount the possiblity that there are many errors still in this file, but I am going to assume for the moment that my current problem is not related to any issues in this static library.
2. Copied the static library "DaveExtention.a" to my PC where I have flash CS5.5 installed (yes, I know there is a typo in the name)
3. In my app folder, I created a lib folder that now contains the following files:
D:\GoldSun\Source Code\Flash\ExtentionTest\lib\DaveExtension.fla
D:\GoldSun\Source Code\Flash\ExtentionTest\lib\DaveExtension-app.xml
D:\GoldSun\Source Code\Flash\ExtentionTest\lib\com\extensions\DaveExtension\DaveExtension.as
D:\GoldSun\Source Code\Flash\ExtentionTest\lib\com\extensions\DaveExtension\BatteryStateEnum.as
I set my project to compile an swc into the build folder and simply put the following code into my project:
import com.extensions.DaveExtension.BatteryStateEnum;
import com.extensions.DaveExtension.DaveExtension;
var ext:DaveExtension = new DaveExtension;
var batterystate:BatteryStateEnum;
stop();
I then publish the swc.
4. Once the swc is created in the build folder, I copy the libDaveExtention.a to the build folder and create the extension.xml file, which looks like this:
<extension xmlns="http://ns.adobe.com/air/extension/2.5">
  <id>com.extensions.DaveExtension</id>
  <versionNumber>1</versionNumber>
  <platforms>
    <platform name="iPhone-ARM">
        <applicationDeployment>
            <nativeLibrary>libDaveExtention.a</nativeLibrary>
            <initializer>ExtInitializer</initializer>
            <finalizer>ExtFinalizer</finalizer>
        </applicationDeployment>
    </platform>
  </platforms>
</extension>
5. I make a copy of the swc file and rename it to .zip... I then extract library.swf from it and delete the zip. My build folder now looks like this:
D:\GoldSun\Source Code\Flash\ExtentionTest\lib\Build\DaveExtension.swc
D:\GoldSun\Source Code\Flash\ExtentionTest\lib\Build\extension.xml
D:\GoldSun\Source Code\Flash\ExtentionTest\lib\Build\libDaveExtention.a
D:\GoldSun\Source Code\Flash\ExtentionTest\lib\Build\library.swf
6. I downloaded the flex 4.5.1.21328 sdk and the Air 3.0 sdk, which I copied into the flex sdk folder (which is located in "D:\SDKs\flex_sdk_4.5.1.21328")
7. In my build folder, I create a simple batch file called buildane.bat with the following command:
D:\SDKs\flex_sdk_4.5.1.21328\bin\adl -package -target ane DaveExtension.ane extension.xml -swc DaveExtension.swc -platform iPhone-ARM library.swf libDaveExtention.a
8. I then open a command prompt to my build folder and run buildane.bat and this is my output:
D:\GoldSun\Source Code\Flash\ExtentionTest\lib\Build>buildane.bat
D:\GoldSun\Source Code\Flash\ExtentionTest\lib\Build>D:\SDKs\flex_sdk_4.5.1.21328\bin\adl -package -target ane DaveExtension.ane extension.xml -swc DaveExtension.swc -platform iPhone-ARM library.swf libDaveExtention.a
application descriptor not found
No matter what I try, I can't get passed this.
Can anyone tell me what I am doing wrong?

Either its a typo or by mistake you wrote adl in yout bat file. Change it to adt since that is the file that will package your ane. adl is just used for debugging/running on Desktop.
Hope this helps. let me know how it goes.
Thanks,
