So something to consider is that Formatter.formatIpAddress(int) is being deprecated: This method was deprecated in API level 12. Use getHostAddress(), which supports both IPv4 and IPv6 addresses. This method does not support IPv6 addresses. So using formatIpAddress(int) is likely not a good long term solution, although it will work. Here is a potential solution if … Read more
NOTE: For a recent, up-to-date answer, see this one below! After a lot of googling and debugging, I believe this is the correct way to determine if Wifi has connected or disconnected. The onReceive() method in the BroadcastReceiver: public void onReceive(final Context context, final Intent intent) { if(intent.getAction().equals(WifiManager.NETWORK_STATE_CHANGED_ACTION)) { NetworkInfo networkInfo = intent.getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO); if(networkInfo.isConnected()) { … Read more
its an old post but this might help someone… WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE); int numberOfLevels = 5; WifiInfo wifiInfo = wifiManager.getConnectionInfo(); int level = WifiManager.calculateSignalLevel(wifiInfo.getRssi(), numberOfLevels); Documentation: public static int calculateSignalLevel (int rssi, int numLevels)
Actually you’re checking for whether Wi-Fi is enabled, that doesn’t necessarily mean that it’s connected. It just means that Wi-Fi mode on the phone is enabled and able to connect to Wi-Fi networks. This is how I’m listening for actual Wi-Fi connections in my Broadcast Receiver: public class WifiReceiver extends BroadcastReceiver { @Override public void … Read more
android.net.wifi.WifiInfo.getSSID? WifiManager wifiMgr = (WifiManager) getActivity().getSystemService(Context.WIFI_SERVICE); WifiInfo wifiInfo = wifiMgr.getConnectionInfo(); String name = wifiInfo.getSSID();
Using “svc” through ADB (rooted required): Enable: adb shell su -c ‘svc wifi enable’ Disable: adb shell su -c ‘svc wifi disable’ Using Key Events through ADB: adb shell am start -a android.intent.action.MAIN -n com.android.settings/.wifi.WifiSettings adb shell input keyevent 20 & adb shell input keyevent 23 The first line launch “wifi.WifiSettings” activity which open the … Read more
Warning This method will not work beyond 5.0, it was a quite dated entry. Use the class below to change/check the Wifi hotspot setting: import android.content.*; import android.net.wifi.*; import java.lang.reflect.*; public class ApManager { //check whether wifi hotspot on or off public static boolean isApOn(Context context) { WifiManager wifimanager = (WifiManager) context.getSystemService(context.WIFI_SERVICE); try { Method … Read more
The question is about a non rooted device but if it is rooted the simplest way would be to: From the terminal on your phone, do this: su setprop service.adb.tcp.port 5555 stop adbd start adbd See this answer for full details.
Part 1: Creating a WEP WiFi configuration programmatically This is pretty much straightforward, WifiConfiguration exposes the interface to create the same. Here is the sample code: void saveWepConfig() { WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE); WifiConfiguration wc = new WifiConfiguration(); wc.SSID = “\”SSID_NAME\””; //IMP! This should be in Quotes!! wc.hiddenSSID = true; wc.status = WifiConfiguration.Status.DISABLED; wc.priority … Read more
Wifi is not available on the emulator if you are using below of API level 25. When using an AVD with API level 25 or higher, the emulator provides a simulated Wi-Fi access point (“AndroidWifi”), and Android automatically connects to it.
