How to exchange data (objects) between different Android Activities?
<p>What is proper way to exchange data or objects between different Android Activities?</p>

<p>Welcome screen &lt;-> Main Screen &lt;-> Startup routines &lt;-> Processing data &lt;-> Settings</p>

<p>Is it normal/recommended to have more than one activity in Android app? in my opinion, it's somehow strange to have this model of data exchange inside application</p>
