How to create wifihotspot in Oreo programmatically?

Question

Hello Given link question is just showing how to turn on/off wifi hotspot but i want to add create wifi hotspot with SSID and password. I written code for creating wifihotspot(in both NONE and WPA2 PSK) in android and its working fine upto android 7 but in oreo it returning me false value.The summary of my code is-

private WifiManager wifiManager;
private Method method;
private WifiConfiguration config;
config.SSID = ssid;
config.status = WifiConfiguration.Status.ENABLED;
method = wifiManager.getClass().getMethod("setWifiApEnabled",                                           
WifiConfiguration.class, Boolean.TYPE);
boolean status = (Boolean)  method.invoke(wifiManager, config, true);

So my question is how to create wifihotspot in both NONE and WPA2 PSK format for android oreo? Is it possible?

Oreo doesnot support to create hotspot programmatically with no password. It always creates hotspot with unique ssid and key generated randomly.

 WifiManager manager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
 WifiManager.LocalOnlyHotspotReservation mReservation;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        assert manager != null;
        manager.startLocalOnlyHotspot(new WifiManager.LocalOnlyHotspotCallback() {

            @SuppressLint("SetTextI18n")
            @Override
            public void onStarted(WifiManager.LocalOnlyHotspotReservation reservation) {
                super.onStarted(reservation);
                Timber.d("Wifi Hotspot is on now , reservation is : %s", reservation.toString());
                mReservation = reservation;
                 key = mReservation.getWifiConfiguration().preSharedKey;
                 ussid = mReservation.getWifiConfiguration().SSID;


            }

            @Override
            public void onStopped() {
                super.onStopped();
                Timber.d("onStopped: ");
            }

            @Override
            public void onFailed(int reason) {
                super.onFailed(reason);
                Timber.d("onFailed: ");
            }
        }, new Handler());
    }

"LocalOnlyHotspot" does not have internet access. – Always Lucky Dec 11 '18 at 18:32 — Always Lucky, Dec 11 '18 at 18:32

thanks, bro finally I found the solution on your answer,

first adding this (enable the modify setting)

 Intent intent = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS);
        intent.setData(Uri.parse("package:" + this.getPackageName()));
        startActivity(intent);

After pasting your code then adding permissions in manifast

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

location mainly needs

  <uses-feature android:name="android.hardware.wifi" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

The setWifiApEnabled will be deprecated. Looking at the source code, it always returns false :

/**
 * This call will be deprecated and removed in an upcoming release.  It is no longer used to
 * start WiFi Tethering.  Please use {@link ConnectivityManager#startTethering(int, boolean,
 * ConnectivityManager#OnStartTetheringCallback)} if
 * the caller has proper permissions.  Callers can also use the LocalOnlyHotspot feature for a
 * hotspot capable of communicating with co-located devices {@link
 * WifiManager#startLocalOnlyHotspot(LocalOnlyHotspotCallback)}.
 *
 * @param wifiConfig SSID, security and channel details as
 *        part of WifiConfiguration
 * @return {@code false}
 *
 * @hide
 */
@SystemApi
@RequiresPermission(android.Manifest.permission.TETHER_PRIVILEGED)
public boolean setWifiApEnabled(WifiConfiguration wifiConfig, boolean enabled) {
    String packageName = mContext.getOpPackageName();
    Log.w(TAG, packageName + " attempted call to setWifiApEnabled: enabled = " + enabled);
    return false;
}

You can try using ConnectivityManager#startTethering(int, boolean, ConnectivityManager#OnStartTetheringCallback) as said in the javadoc. I personnally never tried it.
