Mon premier programme android pour afficher des informations sur l'interface WiFi / 3G :
- SSID, RSSI
- Mac Address, IP Address, Netmask, Gateway
- DNS Server, DHCP Server, DHCP Lease
Captures d'écran
Code snippet :
/**
* Show WLAN interface informations
* cf. http://www.droidnova.com/get-the-ip-address-of-your-device,304.html
* **/
private void showIPAddress1() {
TextView tv;
WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
DhcpInfo dhcpInfo = wifiManager.getDhcpInfo();
tv = (TextView) findViewById(R.id.id_wlan_ssid);
tv.setText(wifiInfo.getSSID());
tv = (TextView) findViewById(R.id.id_wlan_rssi);
tv.setText(""+wifiInfo.getRssi());
tv = (TextView) findViewById(R.id.id_wlan_mac_address);
tv.setText(wifiInfo.getMacAddress());
tv = (TextView) findViewById(R.id.id_wlan_ip_address);
tv.setText(intToIp(dhcpInfo.ipAddress));
tv = (TextView) findViewById(R.id.id_wlan_netmask);
tv.setText(intToIp(dhcpInfo.netmask));
