A question I get asked quite often is: How do I enable the installation of applications from outside the Android Market? The answer is pretty simple, as long as you know where to look for the setting.

You have to enable untrusted sources in order to install from anywhere outside of the standard location. This even applies for apps you’ve developed, or .apk files you have received or found. Here’s the solution:

  1. Tap the Menu button.
  2. Tap Settings.
  3. Tap Applications.
  4. If the check box for Unknown Sources is unchecked, check it.

You should be able to install apps from anywhere. Warning: Do not install an application from a source you do not trust. Just because this application promises to do everything you’ve ever needed your tablet or smartphone to do, it doesn’t mean it isn’t malicious. Of course, there are applications in the Android Market that are malicious, so use our best judgment when installing apps.
