If you really must make your application unusable when the user's device even temporarily loses its connectivity, you will have to add a listener to a special location called /.info/connected. It will tell you when the SDK thinks it has lost its connected. This is described in the documentation. You will have to write code to make your app behave the way you want when your listener is notified like this.
However, your application may have still written data in the time it took from the moment the connection to became stalled, before the SDK makes a decision that the connection is actually gone. And those writes will still be synchronized.
It's better to just make your application usable offline, and notify the user when their data isn't yet synchronized due to being offline.

Currently, in order to prevent write to Firebase after returning back from offline, I check for internet connectivity before every write operation. And by that I do not mean just checking for network connectivity, but also if there is actual internet access available. I ping google.com in order to find out.
I do not think this is the best way to do that.
So, what is the best practice to just tell Firebase not to cache any write operations when there is no internet connection available and just preview a plain simple "No internet connection available" message?
