Basic Android Programming (6/10) - Miscellaneous. Topics that doesn't really fit well anywhere. ActionBar - a title bar, tool bar, main menu, all rolled into one. It can do tabs too, but that's not covered in this video. Resources - like strings. Everywhere else I will be hard coding strings, but here I will talk about them. Styles - they give your app an uniform look, and can reduce the amount of XML clutter in the layout file. The more XML layout you use, the more you will appreciate these. Compatibility - Android provides a mechanism where the code detects the run time and can skip code as needed.
