How to Install an Android Game Through a PC With APKby Jim Campbell
An APK file contains the installation files for any Android game. If you have an APK file on your PC, you can copy the file directly to your Android device and install the game without connecting to the Android Market. This process is beneficial to test your own custom Android game, or to install a game sent to you by a friend to the phone.
Connect the Android device to your PC using the USB device. Windows mounts a drive to the Android's memory card. Copy and paste the APK file from your computer to the mounted drive.
Tap the "Settings" icon on your Android device. In the list of options, tap the "Applications" icon. Check the option labeled "Unknown Sources." This option allows you to install APK files not verified or uploaded to the Market. Tap "OK" to save the settings.
Tap "Applications" again and tap the "App Installer" application icon. Tap the name of the APK game in the list of applications. Tap "Install" to install the APK to the phone.
