Here’s how to install APK files on an Android emulator.
First, start the Android emulator from Eclipse or another development environment.
The command to install an APK file is “adb install path_to_APK_file”.
% adb install ~/Downloads/myapp.apk 
2427 KB/s (34093911 bytes in 13.715s)
  pkg: /data/local/tmp/myapp.apk 
Success
That’s all you need to do to install an APK file on the emulator.
That’s all from the Gemba.
