Frequently asked questions
- So, is Android not really an operating system, just a virtual machine, and are all the phones and tablets really Linux machines?
No, all the different sub-systems of an Android device, which include Linux, the ART, and the libraries and drivers, are together what make up the Android operating system.
- I still don't understand all these technical terms, such as ART, object-oriented, APK, and so on. Should I re-read this chapter?
No, that isn't necessary as we just needed to introduce this jargon and we will be revisiting it all as well as clarifying it as the book progresses. If you understand the following, you are ready to proceed to Chapter 2, First Contact: Java, XML, and the UI Designer:
We will be writing Java code and creating other resources in Android Point Studio, which, with the help of the JDK, will turn this code and resources into real Android apps.
