Please try below function . If internet connection is available in device then it will return true otherwise it will return false.

public static boolean CheckInternet(Context context) 
{
    ConnectivityManager connec = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    android.net.NetworkInfo wifi = connec.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
    android.net.NetworkInfo mobile = connec.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);

    if (wifi.isConnected()) {
        return true;
    } else if (mobile.isConnected()) {
        return true;
    }
    return false;
}

Add Permission in android manifest file.

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

try {
ConnectivityManager conMgr = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE); 
NetworkInfo info= conMgr.getActiveNetworkInfo(); 

    if(info != null && info.isConnected()) 
    {
        //Internet is there
    }
    else{
        //Internet is not there
    }
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

hope it will help you...
