title: Faster loading times for activities in android app
body: <p>The way I have my app set up now the initial activity that launches displays an options screen which has 4 buttons. Each button when clicked.launches its own activity and layout that goes with it. But when the user clicks a button it takes almost 3-5 seconds.for the activity to open the new screen. Is there a better way of doing this so that it loads faster? Is there a way to launch all of the activities in the background at the start of the app so they are already running? What woiluld be the best/recomended way of dealing with this.</p>
