How To Detect When User Connects To Wifi Or Mobile Internet In Android

I want to check for particular update when user each time connects to internet.I tried the following codes : unfortunately app is getting stopped while checking for network Broadca

Solution 1:

Once I had implemented a check in my app, to see if there is any internet connection or not. You can have a look at this --

publicclassConnectionDetector {

private Context context;

publicConnectionDetector(Context cont){
this.context = cont;
}

publicbooleanisConnectingToInternet(){
ConnectivityManagerconnectivity= (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
if (connectivity != null)
{
   NetworkInfo[] info = connectivity.getAllNetworkInfo();
   if (info != null) {
   for (inti=0; i < info.length; i++) {
   if (info[i].getState() == NetworkInfo.State.CONNECTED) {
        returntrue;
    }
}
}

}
returnfalse;
}
}

You can initialize an object of this class in your OnCreate method.

And finally call this class' method just before you upload files.

BooleanisInternetConnected= cd.isConnectingToInternet();
if (isInternetConnected)
{
    //perform your job here.
}

EDITED::

NetworkInfoactiveNetworkInfo= connectivityManager.getActiveNetworkInfo();
return activeNetworkInfo != null && activeNetworkInfo.isConnected();

Hope this helps.
