title: Run Activity from beginning
body: <p>I have application which when start I run <code>MainActivity</code> and after get some data I choose which next activity should be started. I have a problem with something like that: when I start first time <code>MainActivity</code> start and choose correct activity. When I am in correct activity and use home button and choose again application from menu Application start not from <code>MainActivity</code> but from my correct activity. How can I start my application always from <code>MainActivity</code> even if I use home button to hide application to background and chose from menu button again my app?</p>
