public class NetworkCapabilities extends Object
ConnectivityManagerand when inspecting a network. Note that this replaces the old ConnectivityManager#TYPE_MOBILE method of network selection. Rather than indicate a need for Wi-Fi because an application needs high bandwidth and risk obselence when a new, fast network appears (like LTE), the application should specify it needs high bandwidth. Similarly if an application needs an unmetered network for a bulk transfer it can specify that rather than assuming all cellular based connections are metered and all Wi-Fi based connections are not.
|Modifier and Type||Field and Description|
Indicates that this network should be able to reach the internet.
|Constructor and Description|
|Modifier and Type||Method and Description|
Indicates whether some other object is "equal to" this one.
Gets the capabilities.
Tests for the presence of a capability on this instance.
Returns a hash code value for the object.
Sets the capabilities.

Note that it is generally necessary to override the
hashCode method whenever this method
is overridden, so as to maintain the general contract for the
hashCode method, which
states that equal objects must have equal hash codes.

hashCodemethod on each of the two objects must produce the same integer result.
Object.equals(java.lang.Object)method, then calling the
hashCodemethod on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
As much as is reasonably practical, the hashCode method defined by class
return distinct integers for distinct objects. (This is typically implemented by converting the
internal address of the object into an integer, but this implementation technique is not required
by the JavaTM programming language.)
