The name of the action. Some standard actions are defined in theIntent class as ACTION_string constants. To assign one of these actions to this attribute, prepend "android.intent.action." to the string that follows ACTION_.For example, for ACTION_MAIN, use "android.intent.action.MAIN"and for ACTION_WEB_SEARCH, use "android.intent.action.WEB_SEARCH".

For actions you define, it's best to use the package name as a prefix toensure uniqueness. For example, a TRANSMOGRIFY action might be specified as follows:

<action android:name="com.example.project.TRANSMOGRIFY" />
