Let select the right attachment ;-)

In most cases it isn't necessary to resolve the intent, and you could instead catch the exception in the event that no app is available. For example:

Intent pick = new Intent(Intent.ACTION_PICK, ContactsContract.CommonDataKinds.Email.CONTENT_URI);
try {
    startActivityForResult(pick, REQUEST_CODE);
} catch (ActivityNotFoundException e) {
    Snackbar.make(view, R.string.title_no_contacts, Snackbar.LENGTH_LONG).show();
}

If for whatever reason you do need to resolve/query apps that can handle this intent, then you can declare the corresponding <intent> element. In this case this would be:

<intent>
    <action android:name="android.intent.action.PICK" />
    <data android:scheme="content"
          android:host="com.android.contacts"
          android:mimeType="vnd.android.cursor.dir/email_v2" />
</intent>

Or more succinctly (since a content URI is assumed when only a mime-type is specified):

<intent>
    <action android:name="android.intent.action.PICK" />
    <data android:mimeType="vnd.android.cursor.dir/email_v2" />
</intent>

Specifying the mime-type explicitly is important, since the <intent> won't match the expected <intent-filter> elements without it (we'll update our documentation to make this clearer). The mime-type can be found in the documentation: https://developer.android.com/reference/android/provider/ContactsContract.CommonDataKinds.Email#CONTENT_TYPE

Alternatively, you can find the mime-type for an arbitrary URI via adb:

$ adb shell content gettype --uri content://com.android.contacts/data/emails
Result: vnd.android.cursor.dir/email_v2
