One of the least commented on, but far-reaching changes in Android, is a new signature for the ubiquitous findViewByIdI() method. It’s used by all Android developers, and has remained unchanged since the introduction of Android. If you wanted to save a view reference with specific type, such as Button or TextView, you’d have to include casting syntax. But with the new generic declaration of the method’s return type, the casting expression is no longer needed.
