I would like my app to be able to respond when an email address is "sent" in an intent. for example, when a user clicks on an email address in the contacts app, the gmail and email apps show up. i'd like to get into that list.
my first attempt was to match on scheme="mailto",
<intent-filter>
<action android:name="android.intent.action.SEND" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="mailto" />
</intent-filter>
which did not work. next attempt was to match pathPattern=".@.".
<data android:pathPattern=".*@.*" />
this didn't work, and as the JD's say, that's only meaningful if the host, scheme is specified.
any ideas?

An intent filter declares the capabilities of its parent component — what an activity or service can do and what types of broadcasts a receiver can handle. It opens the component to receiving intents of the advertised type, while filtering out those that are not meaningful for the component.
Implicit intent uses the intent filter to serve the user request. The intent filter specifies the types of intents that an activity, service, or broadcast receiver can respond. Intent filters are declared in the Android manifest file. Intent filter must contain <action>
Starting activities or services. To start an activity, use the method startActivity(intent) . This method is defined on the Context object which Activity extends. The following code demonstrates how you can start another activity via an intent.
An intent is an object that can hold the os or other app activity and its data in uri form.It is started using startActivity(intent-obj).. \n whereas IntentFilter can fetch activity information on os or other app activities.
The Email app uses:
<intent-filter>
<action android:name="android.intent.action.VIEW"/>
<action android:name="android.intent.action.SENDTO"/>
<data android:scheme="mailto"/>
<category android:name="android.intent.category.DEFAULT"/>
<category android:name="android.intent.category.BROWSABLE"/>
</intent-filter>
<intent-filter android:label="@string/app_name">
<action android:name="android.intent.action.SEND"/>
<data android:mimeType="*/*"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
<intent-filter android:label="@string/app_name">
<action android:name="android.intent.action.SEND_MULTIPLE"/>
<data android:mimeType="*/*"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
