How to install android mobile application in mobile phone?

Enable Unknown Sources
Before attempting a manual installation of apps using the .apk files, you must first allow your phone to install from “Unknown Sources” (i.e. non-Market apps).

To do this, navigate to Menu -> Settings -> Applications and check the box marked “Unknown Sources“.

Method 1 to install the apk file  in android mobile phone:
 Step 1: Install File Manager
Android does not natively come with any method of browsing the data on your SD card, so you will need to install a file manager from a market. There are a large variety of file managers available on Android, but my personal favourite is ASTRO File Manager.
Step 2: Connect the android mobile phone and CPU using USB cable.
Step 3: Copy .apk file to SD card
Once you have ASTRO File Manager installed, connect your Android device to your PC using your USB cable. Mount the SD card and copy over the .apk file you would like to install.
Step4: Install .apk
On your Android device, navigate to the .apk file using ASTRO File Manager and select it.
This will open a dialog box allowing you to install the app. Select “Open App Manager“.

On the next two pages, select “Install” and “Install” again to install the .apk.
