That is the normal behavior of app launching. You don't need to do anything special. (And definitely do not at all use the android:launchMode="singleInstance" option. That is a very special behavior that is probably not what you want.)

According to the Android activity lifecycle, it shouldn't be possible to start a second copy on an activity. If it isn't terminated, it will resume the running instance.
