1.android.intent.action.search:告诉搜索服务，这个可以被搜索

/**
* Builds an entire list (suitable for display) of
* activities that are searchable, by iterating the entire set of
* ACTION_SEARCH & ACTION_WEB_SEARCH intents.
*
* Also clears the hash of all activities -> searches which will
* refill as the user clicks “search”.
*
* This should only be done at startup and again if we know that the
* list has changed.
*
* TODO: every activity that provides a ACTION_SEARCH intent should
* also provide searchability meta-data. There are a bunch of checks here
* that, if data is not found, silently skip to the next activity. This
* won’t help a developer trying to figure out why their activity isn’t
* showing up in the list, but an exception here is too rough. I would
* like to find a better notification mechanism.
*
* TODO: sort the list somehow? UI choice.
