Android Question How to send Push Notifications (GCM) from android?

[JoanRPM]

I am able to receive a Push Notification sent from the console.
I know it's possible from Android, but not how.

In "Simple Push Framework" tutorial, Erel says it is possible. ( http://www.b4x.com/android/forum/threads/android-push-notification-gcm-framework-and-tutorial.19226/ )

But do not know how, can anyone help me?

Thank you.

 

[Erel]

You need to know the other device "push id". With the ID you can push messages with the same code that is used in the B4J example: http://www.b4x.com/android/forum/threads/simple-push-framework.35635/

Thanks. I will try.

Thanks. I will try.

I've tried but does not leave me.
Can anyone provide a sample code on how to send a message from the client device to the server?

 

[Erel]

Have you ran the B4J desktop example?

 

[javiers]

Yes, they are running both the device and the example B4j the desktop.

The device registers and receives messages with the B4j desktop. Table SqLite main track appears with two values: key with the device name and value.

But I do not know which is the code for sending a message from the device to B4j.

 

[JoanRPM]

The code is that you receive from Google when you register.
The sample code is the same as Erel said.

 

[javiers]

Done! Thanks.

Is it possible to send message from Android to desktop?

 

[JoanRPM]

I suposse. I only comunicate with 2 and more android devices.
See the Erel #2 response. It is in B4J but I have not tried it.

Regards.

But the desktop app hasn't an id , only the registered android device has the id , right ?

 

[Erel]

The desktop app doesn't need an id. Check the B4J project.

Hi
i checked the B4J source code , but the only way for a Device to call the server is through email and not from a GCM message .
To send a message you need the api key and the device id ,the server is a b4j app and doesn't has a device id

 

[Erel]

I'm sorry I misread your original question. I thought that you want to send a GCM message to another device from the device.

You cannot use GCM to send messages to the desktop. However there are many other simpler ways to send a message to a desktop server (assuming that the network is configured correctly).

My first B4A app does this using Apache web server configured with PHP and MySQL. The app sends messages to a Raspberry PI that controls the opening and closing of my gate at the end of my driveway. The PI also tells me when someone is at my gate by using motion detection seen through the outdoor web cam attached to the PI.
Like Erel said, there are easier ways.
