title: How to replace the first character of a String in Android
body: <p>I am doing an app wherein the user is required to enter his mobile number. In order for my app to be user friendly, I am providing a format for them <strong>(e.g. 09XX-XXX-XXXX)</strong>. After the registration process, the app will automatically text a certain number which compose the user's FirstName, Last Name and Mobile Number. In order for the server to contact the user, I must replace the '0' (which is the first character) with <strong>'+63'</strong>. Can somebody help me on how to replace it?</p>
