I want to set listener to listen on wireless state,can anyone help me with my code
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
...
TelephonyManager wTelephonyManager;
...
wTelephonyManager=(TelephonyManager)getSystemService(Context.WIFI_SERVICE);
wTelephonyManager.listen(new PhoneL(),PhoneStateListener.LISTEN_DATA_CONNECTION_STATE);
connManager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);
//here is the event that i use that i want to listen for wifi change, and the above code is all in onCreate{}
class PhoneL extends PhoneStateListener
{
public void onWifiStateChanged(int state, String nesto)
{
mWifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
//mWifi.isConnectedOrConnecting()
if(mWifi.isConnectedOrConnecting())
{
Toast.makeText(WifiActivity.this,"Ima WIFI",Toast.LENGTH_LONG).show();
}
else
{
Toast.makeText(WifiActivity.this,"! NEMA WIFI",Toast.LENGTH_LONG).show();
}
}
}
//Can anyone please help me creating a listener that will listen to the wifi state and check if wifi is connected or connecting if is not i want to enable data packet traffic through 3g/4g
I came across that problem too, here's how I solved it.
In my activity onCreate(..) I did
this.registerReceiver(mWifiStateChangedReceiver,new IntentFilter(WifiManager.WIFI_STATE_CHANGED_ACTION));
and additionally i created the member 'mWifiStateChangedReceiver' this way
private BroadcastReceiver mWifiStateChangedReceiver = new BroadcastReceiver()
{
@Override
public void onReceive(Context context, Intent intent)
{
// TODO Auto-generated method stub
int extraWifiState = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE, WifiManager.WIFI_STATE_UNKNOWN);
switch (extraWifiState)
{
case WifiManager.WIFI_STATE_DISABLED:
case WifiManager.WIFI_STATE_DISABLING:
enableUI(false);
break;
case WifiManager.WIFI_STATE_ENABLED:
ConnectivityManager conMan = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
while(conMan.getActiveNetworkInfo() == null || conMan.getActiveNetworkInfo().getState() != NetworkInfo.State.CONNECTED)
{
try
{
Thread.sleep(500);
} catch (InterruptedException e)
{
e.printStackTrace();
}
}
update();
enableUI(true);
break;
case WifiManager.WIFI_STATE_ENABLING:
break;
case WifiManager.WIFI_STATE_UNKNOWN:
break;
}
}
};
As you can see, when I get WifiManager.WIFI_STATE_ENABLED
I additionally test if the network is really connected, because a enabled WiFi doesn't mean it's connected. At least this was my guess, that's why I'm waiting till the network is really connected.
