As of now, I observe that DOWNLOAD_EMU is always set to false. It might have been set because of emulator issues.
The download destination will be /sdk/emulator based on this
Also, With AndroidUtil.createSubFolder(androidFolder, "sdk"); some redundent SDKs gets created.
The emulator needs to be launched by selecting the RUN IN EMULATOR option, for now, it's not working on the Windows platform.
