Checking internet connectivity in android

I'm trying to check internet connectivity on recieving sms. But my service is force closing while changing internet state. E.g If I've enabled wifi its working fine but when I disable wifi app becomes closed with error. I'm using this code in onReceive function. Here is the code.

     ConnectivityManager cm = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);

     NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
     boolean isConnected = activeNetwork != null && activeNetwork.isConnectedOrConnecting();

     if(isConnected == true) { 
            Toast.makeText(context, "Internet", Toast.LENGTH_LONG).show();
     }
     else if(isConnected == false){
            Toast.makeText(context, "No Internet", Toast.LENGTH_LONG).show();
     }

Try to use this code

add permission in manifest file

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />


public class ConnectionDetector {
public static boolean isConnectingToInternet(Context context){
    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;
 }
}

call

  ConnectionDetector.isConnectingToInternet(LoginActivity.this);
