As input: an optional extra to be attached to the `ACTION_PROCESS_WIFI_EASY_CONNECT_URI`. If attached, it indicates the bands which the remote device (enrollee, device-to-be-configured) supports. The Settings operation may take this into account when presenting the user with list of networks configurations to be used. The calling app may obtain this information in any out-of-band method. The information should be attached as an array of raw integers - using the `Intent#putExtra(String, int[])`.

As output: an extra returned on the result intent received when using the `ACTION_PROCESS_WIFI_EASY_CONNECT_URI` intent to launch the Easy Connect Operation . This value is populated only by remote R2 devices, and only for the following error codes: `EasyConnectStatusCallback.EASY_CONNECT_EVENT_FAILURE_CANNOT_FIND_NETWORK`, `EasyConnectStatusCallback.EASY_CONNECT_EVENT_FAILURE_ENROLLEE_AUTHENTICATION`, or `EasyConnectStatusCallback.EASY_CONNECT_EVENT_FAILURE_ENROLLEE_REJECTED_CONFIGURATION`. Therefore, always check if this extra is available using `Intent#hasExtra(String)`. If there is no error, i.e. if the operation returns `Activity.RESULT_OK` , then this extra is not attached to the result intent.

Use the `Intent#getIntArrayExtra(String)` to obtain the list.

Constant Value: "android.provider.extra.EASY_CONNECT_BAND_LIST"

### EXTRA_EASY_CONNECT_CHANNEL_LIST

    public static final String EXTRA_EASY_CONNECT_CHANNEL_LIST

Activity Extra: The Channel List that the Enrollee used to scan a network.

An extra returned on the result intent received when using the `ACTION_PROCESS_WIFI_EASY_CONNECT_URI` intent to launch the Easy Connect Operation. This extra contains the channel list that the Enrollee scanned for a network. This value is populated only by remote R2 devices, and only for the following error code: `EasyConnectStatusCallback.EASY_CONNECT_EVENT_FAILURE_CANNOT_FIND_NETWORK`. Therefore, always check if this extra is available using `Intent#hasExtra(String)`. If there is no error, i.e. if the operation returns `Activity.RESULT_OK`, then this extra is not attached to the result intent. The list is JSON formatted, as an array (Wi-Fi global operating classes) of arrays (Wi-Fi channels).

Use the `Intent#getStringExtra(String)` to obtain the list.

Constant Value: "android.provider.extra.EASY_CONNECT_CHANNEL_LIST"

### EXTRA_EASY_CONNECT_ERROR_CODE

    public static final String EXTRA_EASY_CONNECT_ERROR_CODE

Activity Extra: The Easy Connect operation error code

An extra returned on the result intent received when using the `ACTION_PROCESS_WIFI_EASY_CONNECT_URI` intent to launch the Easy Connect Operation. This extra contains the integer error code of the operation - one of `EasyConnectStatusCallback` `EASY_CONNECT_EVENT_FAILURE_*`. If there is no error, i.e. if the operation returns `Activity.RESULT_OK`, then this extra is not attached to the result intent.

Use the `Intent#hasExtra(String)` to determine whether the extra is attached and `Intent#getIntExtra(String, int)` to obtain the error code data.

Constant Value: "android.provider.extra.EASY_CONNECT_ERROR_CODE"

### EXTRA_INPUT_METHOD_ID

### EXTRA_SETTINGS_EMBEDDED_DEEP_LINK_INTENT_URI

    public static final String EXTRA_SETTINGS_EMBEDDED_DEEP_LINK_INTENT_URI

Activity Extra: Specify the intent for the `Activity` which will be embedded in Settings app. It's an intent URI string from `intent.toUri(Intent.URI_INTENT_SCHEME)`.

This must be passed as an extra field to `ACTION_SETTINGS_EMBED_DEEP_LINK_ACTIVITY`.

Constant Value: "android.provider.extra.SETTINGS_EMBEDDED_DEEP_LINK_INTENT_URI"

### EXTRA_SUB_ID

A bundle extra of `ACTION_WIFI_ADD_NETWORKS` intent action that indicates the list of the `WifiNetworkSuggestion` elements. The maximum count of the `WifiNetworkSuggestion` elements in the list will be five.

For example: To provide credentials for one open and one WPA2 networks:

    final WifiNetworkSuggestion suggestion1 =
           new WifiNetworkSuggestion.Builder()
           .setSsid("test111111")
           .build();
     final WifiNetworkSuggestion suggestion2 =
           new WifiNetworkSuggestion.Builder()
           .setSsid("test222222")
           .setWpa2Passphrase("test123456")
           .build();
     final List<WifiNetworkSuggestion> suggestionsList = new ArrayList<>;
     suggestionsList.add(suggestion1);
     suggestionsList.add(suggestion2);
     Bundle bundle = new Bundle();
     bundle.putParcelableArrayList(Settings.EXTRA_WIFI_NETWORK_LIST,(ArrayList<? extends
     Parcelable>) suggestionsList);
     final Intent intent = new Intent(Settings.ACTION_WIFI_ADD_NETWORKS);
     intent.putExtras(bundle);

### canDrawOverlays

    public static boolean canDrawOverlays (Context context)

Checks if the specified context can draw on top of other apps. As of API level 23, an app cannot draw on top of other apps unless it declares the `Manifest.permission.SYSTEM_ALERT_WINDOW` permission in its manifest, and the user specifically grants the app this capability. To prompt the user to grant this approval, the app must send an intent with the action `ACTION_MANAGE_OVERLAY_PERMISSION`, which causes the system to display a permission management screen.

Parameters
`context` | `Context`: App context.

Returns
`boolean` | true if the specified context can draw on top of other apps, false otherwise
