    We need to check if device is connected to Internet on making every API call (or call to Remote server). The function below returns true if device is connected to Internet.

    //**This function tells whether the device having an Internet connection or not**///

        public static boolean isNetworkAvailable(Context context) 
        {
            ConnectivityManager connectivityManager 
            = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
            //System.out.println(activeNetworkInfo.);
            return activeNetworkInfo != null;
        }
    

    We need to add the following permissions in the Manifest file

      <uses-permission android:name="android.permission.ACCESS&#95;NETWORK&#95;STATE" />   
      <uses-permission android:name="android.permission.INTERNET" />
