Hello hyder611112,

There seem to be a couple issues here. The main reason this is failing is told by this message:

WindowsPlatform.get_Compiler: WARNING: Visual C++ 2015 toolchain does not appear to be correctly installed. Please verify that “Common Tools for Visual C++ 2015” was selected when installing Visual Studio 2015.

This would affect all packaging that involves code in any way. Can you try opening up the VS2015 installer from your Programs & Features and ensure that the Common Tools for Visual C++ 2015 is checked?

There seem to be some android specific issues as well but they may be symptoms of the previous problem. After checking the 2015 installation, I would suggest to first ensure that packaging for Windows works. If it does, try to package for Android. If it doesn’t, please post the logs for it.

When you go to package for Android, if it fails, can you send me a screenshot of your settings under Project Settings > Android SDK?
