I have 3 activities, each with map fragments. Now I was wondering how I could use hide and show to allow them to stay loaded in the background once the activity is triggered.
Essentially the user starts on Homescreen, loads up rss feed and map fragment then goes to next activity by clicking button. Then he loads up that activity with map fragment. If the user then clicks the back button the Homescreen has to be reloaded and the same if he goes back to the second activity.
How can I have it so when an activity is loaded if the the user travels to different activity the old activity stays active but hidden in the background so the data is already downloaded when he travels back.
