No push notifications after build from source

hello everyone
When I download the latest version of Traccar Manager from Google Play, push notifications work fine, but when I download the latest version of GitHub (3.1) the push notifications does not work, and also when I rebuild the same version of the source code

Because GitHub version doesn't include any Google services. Which flavor are you building?

Sorry Anton, I did not understand the question

There are two flavors.

Hi,

I need enable push notification in xml? regards

What xml?

traccar.xml
Or where I need enable push notification?

Obviously you have to enable it on the server side, but how is your question is related to the topic?

ok, thanks

which flavor has the play services configuration for push notification?

Which flavors do you see?

is Regular flavors

Yes, it's one of them. But if you want to use Google Play services, including push notifications, you have to use Google flavor.

What property should I modify to choose google flavor? best regards

There's no property. You just need to build the right flavor.
