In the last chapter, we discussed the Android Market and how you can download and install both free and paid apps from it. In this chapter, we’ll discuss other sources for apps you can acquire. Google doesn’t like to lock Android down. Unlike an iPad, your Android lets you install apps from third-party sources without having to
your device. One caveat: Google doesn’t lock Android, but that doesn’t prevent the device manufacturer (or your carrier) from trying to do so. Some tablets, such as the Nook Color and Kindle Fire, use modified versions of Android that prevent you from installing apps from outside sources. In the Fire and Nook’s case, “outside sources” include the Android Market.
