How to Install Emailed APK Files

1. Connect your Android device to the computer using the USB cable. Windows detects the device and mounts a temporary drive to the computer.

2. Download the APK file to the same directory where your Android development kit is installed. Typically, the SDK is installed in the 'C:\eclipse' directory.

3. Click the Windows 'Start' button and type 'cmd.' Press 'Enter' to open the Windows command prompt.

4. Type 'set path=%path%;$Android_SDK_Path' and press 'Enter.' This command option sets the Android's SDK path to the Windows environment path, so the installer can find the necessary files.

5. Type 'adb install c:\eclipse\file.apk' where 'file.apk' is the file emailed and stored in your Android directory. Press 'Enter' to install the package to your device.
