60.10 Summary

Implicit intents provide a mechanism by which one activity can request the service of another, simply by specifying an action type and, optionally, the data on which that action is to be performed. In order to be eligible as a target candidate for an implicit intent, however, an activity must be configured to extract the appropriate data from the inbound intent object and be included in a correctly configured manifest file, including appropriate permissions and intent filters. When more than one matching activity for an implicit intent is found during an intent resolution search, the user is prompted to make a choice as to which to use.

Within this chapter an example was created to demonstrate both the issuing of an implicit intent, and the creation of an example activity capable of handling such an intent.
