steps to Install .apk files in Android emulator (AVD)

Here is the solution to installing the .apk files in AVD which is short for Android Virtual Device. I am assuming that you already know how to install the sdk and setup the Android Emulator.
Just make sure the development environment is set, go to the Android sdk root directory, search for the folder platform-tools and then right click on computer then properties and then choose the advanced system settings, then Environment Variables then find the path option and edit it by adding a semicolon(;) and then pasting in the path of the Platform-tools folder. Now open up the command prompt and type in
cd [path of the "platform-tools" folder]
for eg. cd C:\android-sdk-windows\platform-tools
and then hit enter and now copy the .apk app file to the platform-tools directory and switch back to command prompt
now type in the ADB(Android Development Bridge) command, with still working on the platform-tools folder in command prompt. type the following command
adb install abc.apk 
here abc is the name of the file.
it will take a few minutes and it is all done showing the success message. Do follow the video for more detailed picture on this and enjoy developing on the Android Platform
