I want to check Internet connection throughout the run time of my Android application. I tried using services but seems like it is not the best option. Is there any possible way for me to implement a broadcast receiver with in a service? Or do I have to give up the service and use broadcast receivers alone?
I will show you how to create SMS receiver in a service:
public class MyService extends Service {
@Override
public void onCreate() {
BwlLog.begin(TAG);
super.onCreate();
SMSreceiver mSmsReceiver = new SMSreceiver();
IntentFilter filter = new IntentFilter();
filter.setPriority(IntentFilter.SYSTEM_HIGH_PRIORITY);
filter.addAction(SMS_RECEIVE_ACTION); // SMS
filter.addAction(WAP_PUSH_RECEIVED_ACTION); // MMS
this.registerReceiver(mSmsReceiver, filter);
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);
return START_STICKY;
}
/**
* This class used to monitor SMS
*/
class SMSreceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if (TextUtils.equals(intent.getAction(), SMS_RECEIVE_ACTION)) {
//handle sms receive
}
}
}
It wouldn't be wise to check for the connectivity every second. Alternatively you can listen to the action (ConnectivityManager.CONNECTIVITY_ACTION) and identify if you are connected to an active network or not.
IntentFilter filter = new IntentFilter();
filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
Additionally you can check the network Type that is currently active(Type_WIFI, Type_MOBILE)
This way, you don't need a service that keeps checking the connectivity every second.
You need not to use Service
or BroadCastReceiver
for this purpose. Just check Connection status everyTime you need to ping the server.
you can write a method which checks this and returns a boolean
(true/false) according to connection status.
Below method does the same.
public static boolean isNetworkAvailable(Context mContext) {
try {
final ConnectivityManager conn_manager = (ConnectivityManager) mContext
.getSystemService(Context.CONNECTIVITY_SERVICE);
final NetworkInfo network_info = conn_manager
.getActiveNetworkInfo();
if (network_info != null && network_info.isConnected()) {
if (network_info.getType() == ConnectivityManager.TYPE_WIFI)
return true;
else if (network_info.getType() == ConnectivityManager.TYPE_MOBILE)
return true;
}
} catch (Exception e) {
// TODO: handle exception
}
return false;
}
