Each activity displays a +user interface that allows the user to perform a specific task (such as view a map or take a photo). +To take the user from one activity to another, your app must use an {@link +android.content.Intent} to define your app's "intent" to do something. When you pass an +{@link android.content.Intent} to the system with a method such as {@link +android.app.Activity#startActivity startActivity()}, the system uses the {@link +android.content.Intent} to identify and start the appropriate app component. Using intents even +allows your app to start an activity that is contained in a separate app.</p> + +<p>An {@link android.content.Intent} can be <em>explicit</em> in order to start a specific component +(a specific {@link android.app.Activity} instance) or <em>implicit</em> in order to start any +component that can handle the intended action (such as "capture a photo").</p> + +<p>This class shows you how to use an {@link android.content.Intent} to perform some basic +interactions with other apps, such as start another app, receive a result from that app, and +make your app able to respond to intents from other apps.</p> + +<h2>Lessons</h2> + +<dl> + <dt><b><a href="sending.html">Sending the User to Another App</a></b></dt> + <dd>Shows how you can create implicit intents to launch other apps that can perform an +action.</dd> + <dt><b><a href="result.html">Getting a Result from an Activity</a></b></dt> + <dd>Shows how to start another activity and receive a result from the activity.</dd> + <dt><b><a href="filters.html">Allowing Other Apps to Start Your Activity</a></b></dt> + <dd>Shows how to make activities in your app open for use by other apps by defining +intent filters that declare the implicit intents your app accepts.</dd> +</dl> + |
