There are two types of search in Android: local and global. Local search searches within the current application; global search searches the Web via Google’s search engine. You can initiate either type of search in a variety of ways, including the following:
• You can call from a button or menu choice, which will initiate a local search (unless you override this method in your activity).
• You can directly call to initiate a local or global search, including optionally supplying a search string to use as a starting point.
• You can elect to have keyboard entry kick off a search via , for either local search () or global search ().
In either case, the search appears as a set of UI components across the top of the screen, with your activity blurred underneath it (see Figures 36‑1 and 36‑2).
