A Single, Portable ZIP file to replace Android Studio

[Android Central Question]

Is there a single ZIP file that android developer can download, and is portable (meaning you run from flash drive or portable hard disk), and can develop/build android apps without the need to connect to Internet? (Because the current Android studio requires too much time & resources, e.g. need to connect to the Internet to download separate files, such as gradle)?

So far, there's only 1 Android Studio-like system - Android Studio itself.

You could always use one of the "write once, run on two" systems that let you write the app and output a Java version for Android and a Swift version for iOS.
