Btw, got this from documentation, concentrate on the last sentence : "Every time there's new intent for a "standard" activity, a new instance of the class is created to respond to that intent. Each instance handles a single intent. Similarly, a new instance of a "singleTop" activity may also be created to handle a new intent. However, if the target task already has an existing instance of the activity at the top of its stack, that instance will receive the new intent (in an onNewIntent() call); a new instance is not created." found here : http://developer.android.com/guide/topics/manifest/activity-element.html#lmode
