How to Check Network Connectivity in android Device Programaticaly

First Way Like this..

private void checkNetwork() {

    ConnectivityManager connMgr =

        (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

    NetworkInfo activeInfo = connMgr.getActiveNetworkInfo();

    if (activeInfo != null && activeInfo.isConnected()) {

        wifiConnected = activeInfo.getType() == ConnectivityManager.TYPE_WIFI;

        mobileConnected = activeInfo.getType() == ConnectivityManager.TYPE_MOBILE;

        if(wifiConnected) {

            Log.i(TAG, "WIFI connected");

        } else if (mobileConnected){

            Log.i(TAG, "Mobile Connected");

        }

    } else {

        Log.i(TAG,"Neither Mobile nor WIFi connected.");

    }

  }

 

Second Way Like this..

public static boolean isInternetActivorNot(Context context) {

 ConnectivityManager cm = (ConnectivityManager) context

   .getSystemService(Context.CONNECTIVITY_SERVICE);

 // test for connection

 if (cm.getActiveNetworkInfo() != null

   && cm.getActiveNetworkInfo().isAvailable()

   && cm.getActiveNetworkInfo().isConnected()) {

  Log.v("Util", "Internet is working");

  // txt_status.setText("Internet is working");

  return true;

 } else {

  // txt_status.setText("Internet Connection Not Present");

  Log.v("Util", "Internet Connection Not Present");

  return false;

 }

}
