Need Help in Checking Internet Connection in Android?

Question

Hai Friends, I want to display a toast message to the user, when there is poor or no internet connection, so i have written the following code in my activity.

ConnectivityManager conMgr = ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);

  if (

conMgr.getNetworkInfo(0).getState() == NetworkInfo.State.CONNECTED || conMgr.getNetworkInfo(1).getState() == NetworkInfo.State.CONNECTING ) {

      //notify user you are online

  }       else if (

conMgr.getNetworkInfo(0).getState() == NetworkInfo.State.DISCONNECTED || conMgr.getNetworkInfo(1).getState() == NetworkInfo.State.DISCONNECTED) { //notify user you are not online

      Toast.makeText(getBaseContext(),"Please

Check Your Internet Connection and Try Again",Toast.LENGTH_SHORT).show();

  }

The error message in Log is

10-25 15:52:03.412: ERROR/AndroidRuntime(19084): Caused by: java.lang.SecurityException: ConnectivityService: Neither user 10031 nor current process has android.permission.ACCESS_NETWORK_STATE.

Add the android.permission.ACCESS_NETWORK_STATE permission request to your application manifest:

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