58 CHAPTER 3: Performance 5. Click an object type in the list to see a bar graph that shows the number of objects allocated for a particular memory size in bytes. 6. Click Cause GC again to refresh the data. Details of the heap are given along with a graph of allocation sizes for a particular allocation type. Watch the overall trend in Heap Size to make sure it doesn’t keep growing during the application run. Figure 3-5. php. MAT can help you make sense of the heap output. Now when you dump the heap profile or hprof file (see Figure 3-6), it will be automatically analyzed so you can make some sense of the heap file.

2. Click the icon again to stop collection after a couple of seconds. 3. The IDE will automatically launch the Traceview window and allow you to analyze the results from right within the IDE. 4. Click a method call in the bottom pane to create a hierarchy, showing you the current method, the parent(s) that call this method, and then the children methods called from within the selected method (Figure 3-10). CHAPTER 3: Performance Figure 3-10. Method Profiling in DDMS using Traceview 5. Identify the methods that are taking the most time so you can look at them closer by creating Traceview files, which we’ll explore later in this section.

Optimized Code In the next few pages you’re going to see how some of these optimizations are used in the ToDo List application. java, which has a bare-bones onCreate() method. Listing 3-2. java, shown in Listing 3-3, has many of the Android and Java optimizations mentioned in this chapter; see comments in the code for more information. It also shows how to stop and start profiling using the Traceview API. Listing 3-3. renderTodos(); // TIP: Again, don't allocate unnecessary objects that expand the heap size to significant proportions (DONE) // Once GC occurs, a large amount of the heap memory is dumped, especially with // local data structures, which renders a large portion of the heap unused.
