The popularity of the Android operating system has mushroomed in the past few years as many new Android-based cell phones, tablet computers, and handheld computers have appeared in the marketplace.
Like their competitor, the iPhone, Android-based systems can easily install new programs to add functionality never envisioned by the original developers. The programs must be written for the Android operating system; iPhone programs, Windows programs, Macintosh programs, and other non-Android programs will not work.
Thousands of Android programs are now available, including web browsers, email programs, calorie counters, ebook readers, games, programs to track your personal calendar, database programs for telephone numbers and addresses, and much, much more. Genealogy programs also appear frequently for Android systems.
