Install apps in your android virtual device

Some times we want to install built apps (apk files) in our virtual device.
It is simple we just have to copy that apk file in to platform-tools folder in Android sdk directory.
Then execute this command in command prompt in platform-tools directory.

            adb install appName.apk

"appName.apk" should replaced by name of the app that you want to replace.

see the following example screen shot.
