I am creating wifi hotspot in my phone and I want get its state change event when I switched on or off hotspot.
Please look at the following code. This will help you
public class WifiApManager {
private final WifiManager mWifiManager;
public WifiApManager(Context context) {
mWifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);
}
/*the following method is for getting the wifi hotspot state*/
public WIFI_AP_STATE getWifiApState() {
try {
Method method = mWifiManager.getClass().getMethod("getWifiApState");
int tmp = ((Integer) method.invoke(mWifiManager));
// Fix for Android 4
if (tmp > 10) {
tmp = tmp - 10;
}
return WIFI_AP_STATE.class.getEnumConstants()[tmp];
} catch (Exception e) {
Log.e(this.getClass().toString(), "", e);
return WIFI_AP_STATE.WIFI_AP_STATE_FAILED;
}
}
/**
* Return whether Wi-Fi Hotspot is enabled or disabled.
*
* @return {@code true} if Wi-Fi AP is enabled
* @see #getWifiApState()
*/
public boolean isWifiApEnabled() {
return getWifiApState() == WIFI_AP_STATE.WIFI_AP_STATE_ENABLED;
}
}
Where WIFI_AP_STATE is an enum which is as follows
public enum WIFI_AP_STATE {
WIFI_AP_STATE_DISABLING,
WIFI_AP_STATE_DISABLED,
WIFI_AP_STATE_ENABLING,
WIFI_AP_STATE_ENABLED,
WIFI_AP_STATE_FAILED
}
