Use a BroadcastReceiver and declare it in the
AndroidManifest
with...You wil also need...
...in the manifest.
In the
onReceive(...)
method of theBroadcastReceiver
check theIntent
to see what change has occurred - if it has changed to connected, you can start a sync operation.To perform the sync, use an IntentService which will perform the work on a worker thread and then self-terminate when the work is done.
If you want periodic backups, you should also consider using AlarmManager to create a repeating alarm which can be used to fire the
IntentService
at regular intervals. In this case theIntentService
will obviously have to perform an explicit check to see if there is a connection to the Internet available.
