as3c2dm – AIR native extension to push notifications with C2DM
In this short video recording you will see my new and first AIR native extension (ANE) that I created for C2DM (Android Cloud to Device Messaging Framework).
C2DM allows you to push notifications to your Android applications. The cool thing about it is that your application doesn’t have to run in the background in order to receive messages. In this case, my ANE creates a notification with a specified ticker, title and text. When the user taps on the notification it runs an AIR application and passes the sent message text that is displayed in the app. Check out the magic for yourself in the video below.
The source code is available here. You can also download the packaged ANE and the C2DM Messanger app from here and here.
Check out some more already built ANE’s here.

Is there a possibility to add the receive listening upon installation before user is running the application for the first time ?
Gadi
2 Oct 11 at 10:55 pm
@Gadi I don’t think so, at least not with current implementation in as3c2dm because before you can start using it you have register users phone and the application in c2dm service. This is done through AIR part of the app when the app receives back a registration event.

Hi,
I have android jar that calls over JNI .so library. Now I want to add it in AIR app. However when I pack all together in AIR apk, it throws linkage exception. I unpacked APK and saw that .so shared libs are not there.
Any thoughts how can fix this problem?
Thanks,

Hi Piotr, i’ve signed for android c2dm and made a simple android app exactly like yours, the problem is that i don’t receive any notifications and i can’t register either and i’m assuming this is because the android manifest, can you please tell me what changes should i make here
yonodo
14 Oct 11 at 3:27 pm
@yonodo did you register your app id with air. prefix and .debug suffix?
Piotr Walczyszyn
14 Oct 11 at 5:14 pm
@Piotr: I’ve registered my app with com.dg.testapp
yonodo
15 Oct 11 at 12:43 pm
@yonodo you should register with air. prefix because this is what AIR runtime adds to your app id in the background. Also when you are running in the debug mode it adds .debug at the end of id, so you should register for both and Google C2DM registration form.

Hi Piotr,
I downloaded as3c2dm-example.fxp, and tried to import to my 4.5 premium version flash builder. When I am importing, it shows java null pointer exception. Do you have any suggestions for that? Again, I tried to build my own project with the .ane file that you provided, but my flash builder can not recognize the com.riaspace.c2dm package.I need your suggestions.

Hi, I’m trying to use this ANE as you are in your example but the c2dm.register method never dispatches a REGISTERED nor ERROR event.
Any clue?
Gilmar.
Gilmar
26 Oct 11 at 6:20 pm
@Gilmar I suspect that you have a mismatch of your application id and what you registered at google c2dm service registration form.
Remember that you have to register app id with air. prefix and .debug suffix if you are running in debug mode which you probably do during development.

Hi Piotr,
do you have an estimate how hard it would be to get iOS server based push to work?
We would need this shortly and maybe we could also sponsor the development for this…
or start learning objective-c

Hi,
I have just release a blog post about creating a NativeAlert extension for AIR. It includes multiple buttons and dispatches ActionScript events when the user selects one of those buttons.
the post can be found here.
http://www.liquid-photo.com/2011/10/28/native-extension-for-adobe-air-and-ios-101/
The source is on github and you can download the NativeAlert.ane file directly also
Hope you guys like it.

Hi Piotr,
I am sorry that I could make my question clear to you. Just a simple question now. Is it possible to use ane file in 4.5 premium version flash builder. If yes then how?
Regards,
Nahid
Nahid

Hi, Piotr!
I also am getting the Java Null Pointer exception when attempting to load or build the sample. Using Flash Builder 4.5 Premium on a Mac w Snow Leopard.
Thanks!

Pete, I think the problem is that you are importing the project into FB 4.5, and the source files are updated for the 4.6 prerelease version.

Hi Piotr, many thanks for putting this together for the community, I cant tell many people will owe you one
I do have a problem getting all this figured and would like some assistance if possible.
Question 1) namespace used as registration for C2DM, say I desire to signup with com.company.product (which is my app home ns), according to your suggestion we should sign with 2 namespaces:
a) air.com.company.product (used for production environment).
b)air.com.company.product.debug (used for debugging in flex builder).
Leonardo
4 Nov 11 at 8:47 am
Question 2) What do we need to do to set this up in FB 4.5 ( I know the project was recently updated to 4.6 – prerelease – which offers a more nicely UI to do it).
I tried to figure it out by following this: http://blogs.adobe.com/actionscriptdocs/2011/10/using-flash-builder-4-5-1-to-compile-an-air-app-that-uses-a-native-extension.html
But that didnt help much. To accomplish step one from the native extension setup (above), what should it do?
Add this http://snipt.org/Qoj5 (XML)
to my app.xml manifest?
If yes or not?
Do I need to do anything or set my ns value somewhere to make this work? eg: air.com.company.product ?
Thanks In advance,
Leo
Leonardo
4 Nov 11 at 8:47 am
@Leonardo this is correct you should register with air prefix and for development with debug suffix.
Also you have to properly configure Android permissions which should contain your app id.

Just wanted to say ‘thanks very much’ for this. A small demo app like this is perfect to show how this c2dm functionality works.
Great work!

6 Nov 11 at 2:48 pm
Thank you, Piotr! Works perfectly!
I would like to add to the wishlist that the extension could use the 36 or 48 px version of the application icon – if possible. Scaling down the 72 px version doesn’t always look good. I had to simplify the 72 px application icon to make the notifications look decent.
Thanks…
Anders
23 Nov 11 at 2:44 pm
Another thing to the wishlist: A function to remove all notifications for the app. I have noticed many of my users click the application icon instead of the notification, which leaves the notification in the status bar. It would be nice to have the possibility to delete all notifications for the app (“all read”).
Anders
24 Nov 11 at 4:11 pm
Hi Piotr, great work!
Just one small issue though, with flex 4.6 if an app is packaged with the captive Air Runtime, the icon that displays for notifications is the adobe air icon and not the application’s own icon.
When not using the captive runtime the app’s own icon is used properly.
I know this isn’t the fault of your code, but do you know of a workaround to use the captive runtime, and still have your own app icon show up on push notifications?

Hi Piotr, i’ve tried your example but when i run the cd2m app on my device and click on Register, after a few seconds, i get a popup saying the app cause and error and a force close button.
Any help? Thanks

How do I add vibration & sound to the messenger? I couldn’t find the format required anywhere.
I added the vibrate permissions to the app and tried to add in the btnSend_clickHandler function this:
obj["data.vibrate"] = 1000;
obj.vibrate = 1000;
Arik
19 Dec 11 at 2:59 pm
@Arik for vibrations and sound you should use different ANE. You can find more here: http://www.adobe.com/devnet/air/native-extensions-for-air.html

Hello,
I have some silly questions, but those are taking a lot of time. If anyone answers my questions, that will save my time. I don’t understand how to register with air prefix and with debug suffix. Can anyone help me how to do that? Again when I am registering my appliction with google c2dm, what would be “Package name of Android app”? I created an application named PushNotification where I am usning as3c2dm ANE file. Thanks in advance for your patience to answer my questions.
Thanks,

Seems like the video on this pageis broken. Is there anyway you could write up or link to a step by step tutorial on how to get this to work in our own projects? Including what android permissions need to bechanged inside the AIR XML.
Thanks a lot.

I really appreciate that fact that you included all the components of the extension (native code and AS3 code), so it’s a great example to look at when learning how to develop extensions.

Hi Piotr, many thanks for this great example.
Though I’m wondering, why are you specifying “” in the manifest.xml file, while C2DM and Adobe Air are supported from SDK version 8 and onward? Any particular reason?
Michiel
21 Feb 12 at 11:27 am
Commenting system ate part of my comment. Between “” should be: “uses-sdk android:minSdkVersion=”8″”
Michiel
21 Feb 12 at 11:28 am
And by 8 I mean 10. The example manifest tells us 10.

21 Feb 12 at 11:30 am
Hi Piotr, i’ve tried your sample and runs perfect. When i try the same on my app i receive this error on FB when compiling and it’s only happens when incorporate your library and modifications on the manifest file. If i delete all de mods, the apps compile and runs ok:
An internal error occurred during: “Launching Android Version”.

Hello Guys! I have a problem with .ane extension import in this example (I’m using FB 4.6 and I made all necesarry changes required see: http://www.youtube.com/watch?v=qddHBBQHBGE&feature=player_embedded#!) but no result.
All I have is this error: VerifyError: Error #1014: Class com.riaspace.c2dm::C2DM could not be found.
I just don’t get it: I started new Android Mobile Project. I imported the .ane extension and in scripting added some imports like:
import com.riaspace.c2dm.C2DM;
import com.riaspace.c2dm.events.C2DMErrorEvent;
import com.riaspace.c2dm.events.C2DMRegistrationEvent;
Work’s fine.
But when I tried to declare: private var c2m:CMD
I get same error.

Eileen, even I (owner of FlexBrasilia.com.br) am having this same issue. I just woke up today, tried to debug the app that was working fine before and now it’s not working anymore. My bet is on an FB update. Because I’m also having an Alert from FB about error/warning on the ane when I try to debug it. And I never got this Alert before. I’ll come back here if I find the problem.
