title: How to change font size programmatically in Android?
body: <p>I need to change the font size of my application at runtime. I referred the following <a href="https://stackoverflow.com/a/44385047/6680585">SO post</a> where they speak about applying font size via styles.xml and applying it. I think it's applicable only for a particular element (like TextView or layout) but is it possible to apply the font size at application level and is it possible to set it programmatically?</p>
