When i click on AVD Manager, i am getting an error as in the screenshot below.
Referred to the following links. But none of the solution works for me.
Failed
My android.bat file was missing when updating the particular SDK package and my computer suddenly shut down. Thus, my tools folder became empty.

You can recover your android.bat file from temp folder

Manually unzip tools_r23.05-windows or any tool_rXX.zip file (red color)
Get a folder called tools (orange color)
Copy all the file in this folder to the original tools folder (outside temp folder, e.g. D:\android-sdk\tools)
In my case, the problem was solved this way. Hope this helps.
