یه نمونه استفاده از کلاس broad cast receiver

sample broad cast receiver

package com.example.testapp1;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;

public class MBroadcastReceiver extends BroadcastReceiver {

    interface StatusInternet {
        void getStatus(boolean data);
    }

    StatusInternet statusInternet;

    public MBroadcastReceiver(StatusInternet callBack) {
        statusInternet = callBack;
    }


    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent != null && intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION)) {
            if (getInternetStatus(context)) {
                statusInternet.getStatus(true);
//                    Toast.makeText(this, "network is available type mobile data", Toast.LENGTH_SHORT).show();
//                textView.setText("network is connected");
            } else {
                statusInternet.getStatus(false);
//                textView.setText("network is not connected to net");
            }
        }

    }

    private boolean getInternetStatus(Context context) {
        ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();

        if (networkInfo != null && networkInfo.isConnectedOrConnecting()) {
            if (networkInfo.getType() == ConnectivityManager.TYPE_MOBILE) {
                return true;
            } else if (networkInfo.getType() == ConnectivityManager.TYPE_WIFI) {
                return true;
            }
        } else {
            return false;
        }
        return false;
    }

}

registering in main activity is like :

registerReceiver(new MBroadcastReceiver(this), new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION));
