Did you add the PushService module from the example?

 

[donnyy]

yes, i did. I basically used the files from the zip file, then follow your instructions and make the changes using your sample files. The only thing i did that is not in your instructions is, I added reflexion to the library, and then compile it, and then i got the error message.

Sorry Erel, i just realized i was trying to test the push notification with my old file, which doesn't have pushservice module. However, after i added the module and then tried it again, i got the following message instead:

java.lang.RuntimeException: Unable to start service com.dispatch.test.pushservice@47c1f908 with Intent { act= cmp=com.dispatch.test/.pushservice (has extras) }: java.lang.RuntimeException: java.lang.SecurityException: Not allowed to start service Intent { act=com.google.android.c2dm.intent.REGISTER (has extras) } without permission com.google.android.c2dm.permission.RECEIVE

Does this mean google hasn't accepted my app yet? But i did get an email back from Google after i registered my app.

Hi Erel, I have figured it out, it was my manifest, it got overwritten when i compiled the program. Now everything works. Thanks

Hi Erel, I have another question, this is kind of out of the scope of your software, I hope you can point me to the right direction. I have tried to send a message from my Linux server using your c2dm (I have the php and jar files copied over), but when I execute the command, I got the following error:

java.lang.RuntimeException: Unknown method: %*
at anywheresoftware.b4a.c2dm.C2DM.main(C2DM.java:234)

Do you know what the right syntax is for Linux in the batch file?

Thanks for your help.

 

[Erel]

I think that it should be $* instead of %*.

 

[donnyy]

Erel, it works. Thanks for your help.

 

[donnyy]

Erel, sorry to be a pain. I got another question, when i execute the command in linux command line, the message i got is just the first word of the message, even though i have put quotes on the message. Any idea how i can do this please?

 

[Erel]

Sorry but I don't know.

 

[donnyy]

Thanks anyway. If I figure it out, I will let you know.

 

[donnyy]

Erel, I have it figured out. Running the command on Linux with 'send' will only send the first word, but if I put the message in a file and then use sendtextfile to send the message, it will send the whole message. Thanks for all your help and your wonderful script.

Hi Erel,

I have another question with the push notification, in the pushservice program, instead of using the toastmessageshow, is it possible to use a msgbox to display the message instead? I have tried changing it to a msgbox but it comes up with the following error:

android.view.WindowManager$BadTokenException: Unable to add window — token null is not for an application

Looks like it is because of the dialog box, is it because the pushservice is running in the background?

Thanks

You cannot use a msgbox in a service. Msgbox can only be used in Activities. However,you can use a process global variable to assign the pushed message value to it and then display a msgbox in the activity, showing the value of the variable.

Thanks Salmander. I will give it a try, I am still a newbie to this software.

Thanks Salmander. I will give it a try, I am still a newbie to this software.

No worries mate. I am sort-of newbie as well. Just shared what I have learnt. Good luck.

H Salmander, just wondering if you can help me again. I have changed my program to use CallSub to Main to pop-up a message box, and it worked. However, it is not showing the message, this is what i have set up in Main:

Sub Process_Globals
Dim NewMsg As String

Sub ShowNewMessage
Msgbox(NewMsg,"New Message arrived")
End Sub

In PushService, I have this in Sub MessageArrived:

ToastMessageShow("New message: " & Data, True)
NewMsg = Data
CallSub(Main,"ShowNewMessage")

Am I doing this wrong? The toast message shows up but not the NewMsg

Thanks.

 

[donnyy]

I have figured it out, i need to change NewMsg to Main.NewMsg in order to reference the variable I initialized in Main.

i have downloaded your file and tried to run it, it came back with a google permission error when i tried to register. When you register c2dm with google, did you get an email from google?

I signed up to C2DM just after it went public. I took approx 48 hours to get an email confirming access, not sure how long it takes now though sorry.

Am I able to send a msg to one specific device? Or do I have to send a msg to all devices using my app?

Thanks...
