Shared information between some Android activities
<p>I am new in Android and I'm developing my first app. Right now I have been able to implement some activities that work on their own and share information through intents, bundles, etc.</p>

<p>The problem is that a have a list that I manipulate in several activities and I don't want to pass it each time I change my activity. What I want is to have the same list for all the activities so if I change it in Activity1 I'm also changing it in Activity4. </p>

<p>I don't know what would be the best approach to do this. Can anyone guide me a little bit? </p>
