How to build an android chat application ?

Does it work in any of these scenarios?

It doesnt work. You mentioned that Device ID is a randomly generated UUID however a real device serial number has the same number with the one that is been registered on the server by using Backendless.Messaging.registerDevice(…)

Does the device-to-device scenario work?

I ran the generated app on a device and emulator. Worked just fine for me. I could also set breakpoints in ChatActivity.java and see the messages arriving. See the screenshots below:

Hi, Shikhar.
There are monthly limits on messages. You’ll need to pay for exceeding these limits.

The error says the channel name you’re using is either null or empty.

Thank you sir, I manage to enable API, so where do i get the channel name. please have look on my screenshot.

Make sure to pass the channel name into the API call.

Thanks a lot its working pretty fine now!!
