How to detect when user connects to wifi or mobile internet in android

Question

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

Broadcast receiver for checking internet connection in android app

Manifest.xml

<uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> <receiver android:name=".UpdateReceiver" > <intent-filter> <action android:name="android.net.conn.CONNECTIVITY_CHANGE" /> </intent-filter> </receiver>

Java

public class UpdateReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE ); NetworkInfo activeNetInfo = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE); boolean isConnected = activeNetInfo != null && activeNetInfo.isConnectedOrConnecting(); if (isConnected) Log.i("NET", "connecte" +isConnected); else Log.i("NET", "not connecte" +isConnected); } }

My problem is these codes only receive only once , If the user disconnect wifi and reconnects the BroadcastReceiver unable to notify.Any help is appreciated .

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 --

public class ConnectionDetector { private Context context; public ConnectionDetector(Context cont){ this.context = cont; } public boolean isConnectingToInternet(){ ConnectivityManager connectivity = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE); if (connectivity != null) { NetworkInfo[] info = connectivity.getAllNetworkInfo(); if (info != null) { for (int i = 0; i < info.length; i++) { if (info[i].getState() == NetworkInfo.State.CONNECTED) { return true; } } } } return false; } }

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

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

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

EDITED::

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

Hope this helps.

brother i need to identify ( receive ) notification when user reconnects to internet now i am using a timer with interval 10 minutes i want to avoid timer and need when user reconnects to internet
@SigmaEquties -- In that case, you can probably change the return statements to return whenever it represents the first connected network interface or null if none of the interfaces are connected. I have modified my answer above. Please check the edited section.
