Is it possible for a third party app to open a WiFi Hotspot on Android? Following is basically the crux of how I am doing this.

public void setWifiApEnabled(int channel) {
    WifiConfiguration wifiConfig = new WifiConfiguration();
    wifiConfig.SSID = "GunaMelodyHotspot";
    wifiConfig.preSharedKey = "Melody123";
    wifiConfig.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
    wifiConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
    wifiConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
    wifiConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
    wifiConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
    wifiConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
    wifiConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
    wifiConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);

    // Using reflection to set the hotspot configuration
    try {
        Method setWifiApConfigurationMethod = wifiManager.getClass().getMethod("setWifiApConfiguration", WifiConfiguration.class);
        setWifiApConfigurationMethod.invoke(wifiManager, wifiConfig);

        Method getWifiApStateMethod = wifiManager.getClass().getMethod("getWifiApState");
        int state = (int) getWifiApStateMethod.invoke(wifiManager);

        if (state == 12 || state == 13) { // AP state is enabled or enabling
            Method getWifiApConfigurationMethod = wifiManager.getClass().getMethod("getWifiApConfiguration");
            WifiConfiguration currentConfig = (WifiConfiguration) getWifiApConfigurationMethod.invoke(wifiManager);

            if (currentConfig != null) {
                Field apBandField = currentConfig.getClass().getDeclaredField("apBand");
                Field apChannelField = currentConfig.getClass().getDeclaredField("apChannel");

                apBandField.setAccessible(true);
                apChannelField.setAccessible(true);

                apBandField.setInt(currentConfig, 0); // 0 for 2.4GHz, 1 for 5GHz
                apChannelField.setInt(currentConfig, channel);

                setWifiApConfigurationMethod.invoke(wifiManager, currentConfig);
            }
        } else {
            Log.e("HotspotHelper", "Failed to set hotspot configuration");
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

I have the following permissions decalred in my AndroidManifest.xml

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

But I get the following exception.

W System.err: Caused by: java.lang.SecurityException: App not allowed to read or update stored WiFi AP config (uid = 10370)

Is it somehow allowed for a normal third-party to create a hotspot on Android?
