Intent (Android)
open-in-new
<h2 id="description">Description</h2> <p>The concept was created as a way to allow developers to easily remix different apps and allow each type of <a href="/facts/Task_analysis/LzaFdGBP">task</a> (called <i>activity</i>) to be handled by the application best suited to it, even if provided by a third party. Although the concept was not new, the Android architecture doesn't require <a href="/facts/Elevated_privilege/7eS1wna4">elevated privileges</a> to access the components, which makes it an <a href="/facts/Open_platform/y5WEFeJR">open platform</a>.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> </p><p>Activities in Android are defined as classes that control the life cycle of a task in the user interface. The activities supported by an application are declared in a <a href="/facts/Manifest_(computing)/h8PEdvVx">manifest</a>, so that other applications can read what activities are supported. Intents in one application can start particular activities in a different application, if the latter supports the message type of the Intent.<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> </p><p>An analysis in 2011 by researchers from <a href="/facts/University_of_California%2c_Berkeley/MXVEjklr">The University of California at Berkeley</a> found that Intents can pose a <a href="/facts/Security_risk/tbBEDA0V">security risk</a>, allowing attackers to read content in messages and to insert malicious messages between applications. <a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> </p> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>Ferrill, Paul (2011).
