Notify other activities of the same application to finish it self from one activity
<p>I'm working on an application which have 5 activities and any of the activity can access other 4.  In one of the activities i have a <code>Finish</code> button that should put my application on background thread. I want to notify my other activities to call <code>finish()</code>, and for that i have two ideas in mind. One is by using <code>intent</code> but other is using <code>interface</code> but i'm little confused to decide on which way should i go? </p>

<p>Are there any other way to notify all activities on same application from an event of one activity?</p>

<p>Thanks</p>
