The following is the first few sections of a chapter from The Busy Coder's Guide to Android Development, plus headings for the remaining major sections, to give you an idea about the content of the chapter.


PackageManager Tricks

PackageManager is your primary means of introspection at the component level, to determine what else is installed on the device and what components they export (activities, etc.). As such, there are many ways you can use PackageManager to determine if something you want is possible or not, so you can modify your behavior accordingly (e.g., disable action bar items that are not possible).

This chapter will outline some ways you can use PackageManager to find out what components are available to you on a device.
