Is it possible to set a custom font for entire of application?

Question

I need to use certain font for my entire application. I have .ttf file for the same. Is it possible to set this as default font, at application start up and then use it else

Answer 1

This solution does not work correctly in some situations.
So I extend it:

FontsReplacer.java

public class MyApplication extends Application {

    @Override
    public void onCreate() {
        FontsReplacer.replaceFonts(this);
        super.onCreate();
    }

}
