[Ovmsdev] [Action Required] Update your apps to the latest Firebase Cloud Messaging APIs and SDKs

Sun Jan 7 03:54:01 HKT 2024

Everyone,

we need some auditing & beta test help on this.

I've just finished the migration for the server & App side. Everything 
works fine in my test environment, but I had WTF moments on the way. 
Some magically resolved themselves on the next day, so I have no idea 
why they occured in the first place.

New server code is in Server/fcm, see README for details: 
https://github.com/openvehicles/Open-Vehicle-Server/tree/fcm/v3

The server now uses a child process for FCM communication, as each 
delivery attempt now takes 0.3 seconds. The new code also now 
automatically cleans up expired App tokens.

New App code & build is in Android/master: 
https://github.com/openvehicles/Open-Vehicle-Android/tree/master/latest

The App currently uses my API IDs (File "google-services.json") instead 
of the official OpenVehicles version, this needs to be changed for the 
release. It should nevertheless work with api.openvehicles.com, but I 
haven't tested that yet.

FCM makes it harder to configure an App for other servers than build 
into the App. I've done some experimentation and found a way to still 
keep the configuration as simple as before, i.e. you just need the 
custom FCM sender ID (which now always is the FCM/cloud project ID). 
Caveat is, this uses undocumented behaviour, so may need to be changed 
in the future.

See my comment & explanation here:
https://github.com/openvehicles/Open-Vehicle-Android/blob/master/OpenVehicleApp/src/main/java/com/openvehicles/OVMS/ui/MainActivity.java#L404

Code audits & tests are welcome.

When running your own server, follow the steps described in the README 
to get & install your FCM key. FCM keys btw. don't expire until the year 
10000. Connect your module & App to your server, use "notify raise" to 
send test messages.

Btw, FCM migration doesn't need to be done in a specific order 
(server/App): this is just an API change on both sides, the 
infrastructure behind the scenes is more or less identical. An FCM App 
receives GCM transmissions and vice versa. Please test that as well if 
possible.

We need to finish migration before June 20, as the GCM APIs will then be 
switched off.

Regards,
Michael
