public Builder (long beginTimeMillis, 
                long endTimeMillis)

Constructor that specifies the period for which to return events.

Public methods

setPackageNames

public UsageEventsQuery.Builder setPackageNames (String... pkgNames)

Sets the list of package names to be included in the query.

Note:

An empty Set will be returned by UsageEventsQuery.getPackageNames() without calling this method, which indicates querying usage events for all packages. Apps are encouraged to provide a list of package names. Only the matching names supplied will be used to query.

Parameters
`pkgNames`	`String`: the array of the package names, each package name should be a non-empty string, `null` or empty string("") is omitted.

Returns
`UsageEventsQuery.Builder`	This value cannot be `null`.

Throws
`NullPointerException`	if `pkgNames` is `null` or empty.
