I found Error

" -I C:\\\"Program Files (x86)\"\\Android\\android-sdk\\platforms\\android-21\\android.jar\"";

This Line was missing starting quote of the URL, while it contains ending quoteI fixed error by including quote like this:

" -I \"C:\\\"Program Files (x86)\"\\Android\\android-sdk\\platforms\\android-21\\android.jar\""

Thanks to @Prashant and @Laszlo Lugosi for your attention.
