* This class provides the primary API for managing all aspects of Wi-Fi
* connectivity.
* <p>
* On releases before {@link android.os.Build.VERSION_CODES#N}, this object
* should only be obtained from an {@linkplain Context#getApplicationContext()
* application context}, and not from any other derived context to avoid memory
* leaks within the calling process.
* <p>
* It deals with several categories of items:
* <ul>
* <li>The list of configured networks. The list can be viewed and updated, and
* attributes of individual entries can be modified.</li>
* <li>The currently active Wi-Fi network, if any. Connectivity can be
* established or torn down, and dynamic information about the state of the
* network can be queried.</li>
* <li>Results of access point scans, containing enough information to make
* decisions about what access point to connect to.</li>
* <li>It defines the names of various Intent actions that are broadcast upon
* any sort of change in Wi-Fi state.
* </ul>
* This is the API to use when performing Wi-Fi specific operations. To perform
* operations that pertain to network connectivity at an abstract level, use
* {@link android.net.ConnectivityManager}.

* Request a local only hotspot that an application can use to communicate between co-located

* applications have successfully registered concurrently, they will be sharing the underlying
* hotspot. {@link LocalOnlyHotspotCallback#onStarted(LocalOnlyHotspotReservation)} is called
* when the hotspot is ready for use by the application.
* <p>
* Each application can make a single active call to this method. The {@link
* LocalOnlyHotspotCallback#onStarted(LocalOnlyHotspotReservation)} callback supplies the
* requestor with a {@link LocalOnlyHotspotReservation} that contains a
* {@link WifiConfiguration} with the SSID, security type and credentials needed to connect
* to the hotspot. Communicating this information is up to the application.
* <p>
* If the LocalOnlyHotspot cannot be created, the {@link LocalOnlyHotspotCallback#onFailed(int)}
* method will be called. Example failures include errors bringing up the network or if
* there is an incompatible operating mode. For example, if the user is currently using Wifi
* Tethering to provide an upstream to another device, LocalOnlyHotspot will not start due to
* an incompatible mode. The possible error codes include:
* {@link LocalOnlyHotspotCallback#ERROR_NO_CHANNEL},
* {@link LocalOnlyHotspotCallback#ERROR_GENERIC},
* {@link LocalOnlyHotspotCallback#ERROR_INCOMPATIBLE_MODE} and
* {@link LocalOnlyHotspotCallback#ERROR_TETHERING_DISALLOWED}.
* <p>
* Internally, requests will be tracked to prevent the hotspot from being torn down while apps
* are still using it. The {@link LocalOnlyHotspotReservation} object passed in the {@link
* LocalOnlyHotspotCallback#onStarted(LocalOnlyHotspotReservation)} call should be closed when
* the LocalOnlyHotspot is no longer needed using {@link LocalOnlyHotspotReservation#close()}.
* Since the hotspot may be shared among multiple applications, removing the final registered
* application request will trigger the hotspot teardown. This means that applications should
* not listen to broadcasts containing wifi state to determine if the hotspot was stopped after
* they are done using it. Additionally, once {@link LocalOnlyHotspotReservation#close()} is
* called, applications will not receive callbacks of any kind.
* <p>
* Applications should be aware that the user may also stop the LocalOnlyHotspot through the
* Settings UI; it is not guaranteed to stay up as long as there is a requesting application.
* The requestors will be notified of this case via
* {@link LocalOnlyHotspotCallback#onStopped()}. Other cases may arise where the hotspot is
* torn down (Emergency mode, etc). Application developers should be aware that it can stop
* unexpectedly, but they will receive a notification if they have properly registered.
* <p>
* Applications should also be aware that this network will be shared with other applications.
* Applications are responsible for protecting their data on this network (e.g., TLS).
* <p>
* Applications need to have the following permissions to start LocalOnlyHotspot: {@link
* android.Manifest.permission#CHANGE_WIFI_STATE} and {@link
* android.Manifest.permission#ACCESS_COARSE_LOCATION ACCESS_COARSE_LOCATION}. Callers without
* the permissions will trigger a {@link java.lang.SecurityException}.
