ConnectivityManager is crashing while getting network info

I am new to Android and when I give the following snippet, my Android application is crashing.

ConnectivityManager manager = (ConnectivityManager) this.getSystemService(Context.CONNECTIVITY_SERVICE);
manager.getNetworkInfo(ConnectivityManager.TYPE_WIFI); // Application is crashing in this line.

I also checked the AndroidManifest.xml where I gave the Internet permission to the application. Any help would be really useful for my further work.

I am not sure what you want to say but if you want to check internet connection then you can use this code

/**
     * THIS IS FUNCTION FOR CHECKING INTERNET CONNECTION
     * @return TRUE IF INTERNET IS PRESENT ELSE RETURN FALSE
     */
    public boolean checkInternetConnection() {
        ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

        NetworkInfo activeNetworkInfo = cm.getActiveNetworkInfo();
        return (activeNetworkInfo != null && activeNetworkInfo.isAvailable() && activeNetworkInfo.isConnected());
    }

and dont forget 

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