How a service can post message to a not yet running main activity?

Question

I have a background service that receive notification data messages and i want that is the main activity of the app who will process then. When the main activity is running, i can send the data message to it via LocalBroadcastManager, but my problem is when the main activity is not running ! How the service can send message to the main activity in the way that the main activity will receive the message when it's will start ?

you can save that data in local storage either database or shared preference and when your activity starts check for the value and proceed accordingly — Vivek Mishra, May 10 '17 at 08:02
how you will do this using shared preference ? i mean is their anyway using shared preference to store data in `row` (several records with their fields) like in database ? — zeus, May 10 '17 at 08:12

Also you can save custom array list too in shared preference using gson library easily
