Check the Current Network Connection - Java SDK
To check the current network connection, call getConnectionState() on your SyncSession:
Log.v("EXAMPLE", "Sync state: " + app.getSync().getSession(config).getConnectionState());
Log.v("EXAMPLE", "Sync state: ${app.sync.getSession(config).connectionState}")
Important
Connection States vs. Session States
The SDK manages communication with App Services at two levels: connection state and session state. Connection state tracks the state of the network connection between a client device and your backend App. Session state refers to a single user's synchronization state, which can be paused and resumed in the SDK at will. As a result, you must check both states to determine whether a user's local changes will sync to the backend. Synchronization only occurs when the connection state is "connected" and the session state is "active".
You can also subscribe to connection changes on your SyncSession
with addConnectionChangeListener(),
which works similarly to upload and download listeners.
