Registratio not taking place

1) Google Account Set Up >24 hours ago

2) Modified 'Device Example'
- Package = "my.package"
- SenderId = "myuserid@gmail.com"

3) Changed manifest (5 occurences, did a CTRL+H replace for 'anywheresoftware.b4a.samples.push' in 'my.package')

4) Changed config.txt for desktop tool
- sender_mail_id=myuserid@gmail.com
- sender_mail_password=mypassword

5) Compile errors:

- (Main, line 38) Dim r as Reflector (in the previous post this was already mentioned and it could be commented out)

More errors about 'Reflector', so I downloaded 'Reflection 1.9 library (copied the jar + xml to the add. libs dir)


6) Saved changes, restarted B4A and Enabled reference to Reflection lib

7) Unchecked 'Do Not Overwrite Manifest File' (It was complaining about this during compilation)

8) Now it's running

- So I entered a random name for my device and pressed Register

Nothing happens...

What I'm a missing, doing wrong?

Thank for your help!

You should leave it checked. If it is not checked then AndroidManifest.xml is recreated by the compiler.
You will need to redo the changes and keep it checked.

Thanks for your quick response. I deleted everything, unzipped it all again and made the same changes. Seems I've got a path issue, since the compiler stops with:

Compiling code. 0.12
Using existing AndroidManifest.xml.
(Project - Do Not Overwrite Manifest option is checked)
AndroidManifest-Example.xml file will be created instead.
Generating R file. 0.20
Compiling generated Java code. Error
javac 1.6.0_26
javac: file not found: gen\anywheresoftware\b4a\samples\push\R.java
Usage: javac <options> <source files>
use -help for a list of possible options

You didn't change the Package name (under Project):

Important, disable 2-step authentication!

One more thing, I got the following error due to 2-step authentication. Disabling this made everything work!

java -cp b4a_c2dm.jar anywheresoftware.
b4a.c2dm.C2DM send mydevice "testmessage"
java.lang.RuntimeException: error getting authentication code: java.io.IOExcepti

Need to automate Desktop "sending"

Hi again. Have everything working on my website's server,
but now need to automate the sending msgs/commands to
different Devices. Can you share java code, and or show
how to do it from B4a, or some other means. Also show
GetDevices command using PHP. I would be happy to
buy also b4ppc...

Great product!

Ok it was working fine until it was on b4a server. I moved the script to my host, changing the database username, dbpassword and database name. In the app, I changed the boardURL to my script address. When I register the app, I get registration successful toast but I am getting this message on the command line. "error getting authentication code"

anyone help please?

Ok its working now. :)

I have been following this tutorial for two days now. And I am kind of struggling to understand how I can implement C2DM functionality into my existing project. Can anyone help me please with this? can this not be made into a library like feature for B4A?

Thank you in advance.

Not sure which answer are you looking for. Which problem are you encountering?

Hi Erel, thanks for the reply. I want to implement C2DM functionality into my Project. So I have created a new service module in my project and copy pasted the code from this tutorial's service module into my service module. Now, what do I do in my manifest file?

As mentioned in the first post:

You should then choose Project - Do not overwrite manifest file.

This is my Main Activity
B4X: 
'Activity module

   'These global variables will be declared once when the application starts.
   'These variables can be accessed from all modules.
   
   Dim Package, DeviceBoardPassword, BoardUrl, SenderId, DeviceName As String
   DeviceBoardPassword = "abcd"
   BoardUrl = "http://ssahmed.co.uk/c2dm/c2dm_board.php"

   
   'both these fields should be set to match your application package and SenderId.

   SenderId = "my_email@gmail.com"
   Dim reg As String
   

End Sub

Sub Globals
   'These global variables will be redeclared each time the activity is created.
   'These variables can only be accessed from this module.
   Dim p As PhoneId

   Dim ListView1 As ListView
   Dim Label1 As Label
End Sub

Sub Activity_Create(FirstTime As Boolean)
   Activity.LoadLayout("Main")
   reg = p.GetDeviceId
   Log("The device ID is: " & reg)
   'ToastMessageShow("Starting Service", False)
   Register(reg)
End Sub

Sub Activity_Resume

End Sub

   ToastMessageShow(errorMsg, True)
   Log(errorMsg)
End Sub
What am I missing? Service is not even starting.
