You can use the ConnectivityManager to check the network state.

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

}
