how to pass data from activity to running service

Question

I want to send data to the server periodically, I\'m using background Service for that, but I want to send when the data got updated, and updated data I\'m getting

Answer 1

The best option would be to persist the data on the hard drive (e.g. SharedPreferences, database, ...).

Activity got updated => persist to storage => invoke Service

The Service has to read the data from the chosen storage before sending the data.
