Whats the best way to bring an already running app to the front in android?
<p>I have two apps that I want to be able to switch between without killing each different activity and without re-launching the activity I want to switch back too. </p>

<p>Lets say I have a edittext in each activity and I want the text that is written to stay in that edittext view so that when this activity is brought to the front again it's still there. 
The problem is that I can't use savedinstancestate, shared preferences or a database to store the information. It should just be there while the application is running. So if it's killed in the background and the info disappears it's no problem.</p>

<p>So what could be the best way of switching between two running applications within these two applications?</p>
