My Application looks for the Connectivity-State using a Broadcastlistener. If the Phone is offline, a Snackbar should appear. The Snackbar has an Action, to Open the Networksettings.
If I click on this, my Networksettings were opened. If I don't turn on my Internet and go back to the App, my Snackbar isn't shown again though it is called (Checked it!).
If I set the Snackbar to null and initialise it again, it works!
MainActivity:
@Override
protected void onResume() {
super.onResume();
registerReceiver(networkListener, new IntentFilter("android.net.conn.CONNECTIVITY_CHANGE"));
}
@Override
protected void onPause() {
super.onPause();
unregisterReceiver(networkListener);
}
@Override
public void ToggleSnackbar(boolean ShowHide) {
if (ShowHide) {
snbInternetState.show();
}
else {
snbInternetState.dismiss();
}
bOnline = ShowHide;
}
NetworkListener:
public class NetworkListener extends BroadcastReceiver {
private SnackbarInterface snbInterface;
public NetworkListener(SnackbarInterface snbInterface) {
this.snbInterface = snbInterface;
}
@Override
public void onReceive(Context context, Intent intent) {
ConnectivityManager cm = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo ni = cm.getActiveNetworkInfo();
if (ni == null || !ni.isConnectedOrConnecting()) {
snbInterface.ToggleSnackbar(true);
}
else if (ni != null && ni.isConnected()) {
snbInterface.ToggleSnackbar(false);
}
}
public interface SnackbarInterface {
void ToggleSnackbar(boolean ShowHide);
}
}
Does anybody know how to fix this problem?
Thanks!
