No android to build in Visual Studio

Hello. I got the zip containing unreal engine source code.

I extracted it. Ran setup.bat and ran generateProjectFiles.bat with administrator.
I got a UE4.sln file. Opened it and built Development Editor | win 64.

But I can’t see the android platform in the list to build for android. What do I need to make it appear? Please help me.

You need to install AndroidWorks from the Engine/extras directory, then log out and back in to make sure environment variables update, then run setup.bat again. It only downloads the Android files if NDKROOT is defined. Then, GenerateProjectFiles again and rebuild.

Thank you for your reply. But when I built it, it shows these errors. What should I do? Pls help me.
