How to transmit the APK file to SD card?

You may use one of the below methods:

<1> Data line or Bluetooth: copy the APK file into SD card and install it by connecting your computer and Android phone (so does Andriod Emulator, only does it use some software to connect) with them.

<2> Web server: create a web server on PC and put the APK file in one of its directorys, next visit the web and open the downloading webpage to download the APK into SD card via WiFi or other Network on the android-powered phone (so does Android Emulator).

Note: The emulator is as same as the visiable Android-powered Phone. Merely emulator provides much convenience for APP developpers to test in local computer. Next, I will tech you how to install an Android Emulator in your computer.
