How to install Google Android application from PC

I am sure that probably most people alredy know on how to install apk file(s) (Google Android Application) but because i just want to make sure that i don’t forget this because i just received an android phone last week as a gift and because i don’t have internet access on my mobile phone due to mobile connectivity here is just way to expensive for me, the only way for me to install Android apps is by downloading it on PC and then install it using the Android SDK from PC. Anyway here’s the steps:

1. Download Android SDK and install / extract it somewhere on your hard drive (and optionally download the usb driver, although in my case i don’t need to install the USB driver because i’ve installed the driver from Samsung)

2. Add the tools directory in your Android SDK directory to your environment variables (PATH)

3. Open command prompt and change to the directory where your put the android application
