Merge "[DPP] Add EXTRA to indicate bands support on remote device"

     * Input: The Intent's data URI specifies bootstrapping information for authenticating and

     * provisioning the peer, and uses a "DPP" scheme. The URI should be attached to the intent

     * using {@link Intent#setData(Uri)}. The calling app can obtain a DPP URI in any

     * way, e.g. by scanning a QR code or other out-of-band methods.

     * way, e.g. by scanning a QR code or other out-of-band methods. The calling app may also

     * attach the {@link #EXTRA_EASY_CONNECT_BAND_LIST} extra to provide information

     * about the bands supported by the enrollee device.

     * <p>

     * Output: After calling {@link android.app.Activity#startActivityForResult}, the callback

     * {@code onActivityResult} will have resultCode {@link android.app.Activity#RESULT_OK} if

    /**

     * Activity Extra: The Band List that the Enrollee supports.

     * <p>

     * An extra returned on the result intent received when using the {@link

     * #ACTION_PROCESS_WIFI_EASY_CONNECT_URI} intent to launch the Easy Connect Operation. This

     * extra contains the bands the Enrollee supports, expressed as the Global Operating Class,

     * see Table E-4 in IEEE Std 802.11-2016 Global operating classes. This value is populated only

     * by remote R2 devices, and only for the following error codes: {@link

     * android.net.wifi.EasyConnectStatusCallback#EASY_CONNECT_EVENT_FAILURE_CANNOT_FIND_NETWORK}

     * {@link android.net.wifi.EasyConnectStatusCallback#EASY_CONNECT_EVENT_FAILURE_ENROLLEE_AUTHENTICATION}

     * This extra contains the bands the Enrollee supports, expressed as the Global Operating

     * Class, see Table E-4 in IEEE Std 802.11-2016 Global operating classes. It is used both as

     * input, to configure the Easy Connect operation and as output of the operation.

     * <p>

     * As input: an optional extra to be attached to the

     * {@link #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

     * {@link Intent#putExtra(String, int[])}.

     * <p>

     * As output: an extra returned on the result intent received when using the

     * {@link #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:

     * {@link android.net.wifi.EasyConnectStatusCallback#EASY_CONNECT_EVENT_FAILURE_CANNOT_FIND_NETWORK},

     * {@link android.net.wifi.EasyConnectStatusCallback#EASY_CONNECT_EVENT_FAILURE_ENROLLEE_AUTHENTICATION},

     * or

     * {@link android.net.wifi.EasyConnectStatusCallback#EASY_CONNECT_EVENT_FAILURE_ENROLLEE_REJECTED_CONFIGURATION}.

     * Therefore, always check if this extra is available using {@link Intent#hasExtra(String)}. If

     * there is no error, i.e. if the operation returns {@link android.app.Activity#RESULT_OK}, then

     * this extra is not attached to the result intent.

     * Therefore, always check if this extra is available using {@link Intent#hasExtra(String)}.

     * If there is no error, i.e. if the operation returns {@link android.app.Activity#RESULT_OK}

     * , then this extra is not attached to the result intent.

     * <p>

     * Use the {@link Intent#getIntArrayExtra(String)} to obtain the list.
