How to encrypt and decrypt URL in java?

Question

I am working on an android project and securing my code from reverse engineering using proguard. I'm facing a serious issue my code is secure like 90% secure but issue is with my web services URL. I did save URL's path in separate class like

Public class key_Strings
{
public static url="https://www.google.co.uk";
}

and say i'm using this URL in my activity like :

public class MainActivity extends Activity 
{
@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        String URL=key_Strings.url;

    }
}

after exporting my .APK file i did apply reverse engineering tools and then at the end i get this class with anonymous name but thing is that i get the URL something like:

this.h="https://www.google.co.uk";

i want to secure my URL so need help Thanks

A url is essentially a String. Did you search SO for how to encrypt Strings? — Chetan Kinger, Mar 03 '15 at 16:55

Use DexGuard as recommended in ProGuard FAQ.
