Intent action for network events in android sdk
Here's a working example:
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<receiver android:name=".receiver.ConnectivityReceiver">
<intent-filter>
<action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
</intent-filter>
</receiver>
.
public class ConnectivityReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Log.d(ConnectivityReceiver.class.getSimpleName(), "action: "
+ intent.getAction());
}
}
yanchenko's answer is very much useful, i am just simplifying a little bit to get connection status, please modify onReceive as below :
public class ConnectivityReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Log.d(ConnectivityReceiver.class.getSimpleName(), "action: "
+ intent.getAction());
MyConstants.IS_NETWORK_AVAILABLE = haveNetworkConnection(context);
//IS_NETWORK_AVAILABLE this variable in your activities to check networkavailability.
}
private boolean haveNetworkConnection(Context context) {
boolean haveConnectedWifi = false;
boolean haveConnectedMobile = false;
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo[] netInfo = cm.getAllNetworkInfo();
for (NetworkInfo ni : netInfo) {
if (ni.getTypeName().equalsIgnoreCase("WIFI"))
if (ni.isConnected())
haveConnectedWifi = true;
if (ni.getTypeName().equalsIgnoreCase("MOBILE"))
if (ni.isConnected())
haveConnectedMobile = true;
}
return haveConnectedWifi || haveConnectedMobile;
}
}
