public class FeatureInfo extends Object implements Parcelable
This object is used to represent both features supported by a device and
features requested by an app. Apps can request that certain features be
available as a prerequisite to being installed through the
uses-feature
tag in their manifests.
Starting in Build.VERSION_CODES.N
, features can have a
version, which must always be backwards compatible. That is, a device
claiming to support version 3 of a specific feature must support apps
requesting version 1 of that feature.

If this object represents a feature requested by an app, this is the minimum version of the feature required by the app.
When a feature version is undefined by a device, it's assumed to be version 0.

public String toString()
Object
toString
method returns a string that
"textually represents" this object. The result should
be a concise but informative representation that is easy for a
person to read.
It is recommended that all subclasses override this method.
The toString
method for class Object
returns a string consisting of the name of the class of which the
object is an instance, the at-sign character `@
', and
the unsigned hexadecimal representation of the hash code of the
object. In other words, this method returns a string equal to the
value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
