Chapter 12. The Stack, the Heap, and the Garbage Collector
By the end of this chapter, the missing link between Java and our XML layouts will be fully revealed, leaving us with the power to add all kinds of widgets to our apps as we have done before. However, this time, we will be able to control them through our Java code.
In this chapter, we will get to take control of some fairly simple UI elements, such as Button and TextView, and, in the next chapter, we will take things further and manipulate a whole range of UI elements.
To enable us to understand what is happening, we need to find out a bit more about the memory in an Android device and two areas of it – the Stack and the Heap.
In this chapter, we will learn about the following topics:
- Android UI elements are classes
- Garbage collection
- Our UI is on the Heap
- Special types of class, including Inner and Anonymous
Back to that news flash.
