Android : how to add notification in the Stackbuidler without caching the data?

I am trying to create notifications but for this purpose i am saving the data every time in an array like

            String []events = new String[100];
            events[number]  = msg.getText().toString();

and later On I am adding it like

             for (int i=0; i < events.length; i++) {

                inboxStyle.addLine(events[i]);
            }

instead i want to show the notifications without caching the data like above.
