It can take a very long time for the GUI software called Android Studio just to start up, and then another long time to just load a project (if I'm loading one I worked on previously). I'm interesting therefore in just running command line compilation commands, to do Android app compilation entirely from the command line. I'm already used to doing that in other programming languages (VC++2003, GoAsm, NAsm, TinyCC, Java). And I already have the Java command line compiler installed (which I know I will need anyway for Android app compiling). I just need to know how to run the other tools that will also bee needed for compiling an Android app, from the command line, so I can avoid installing and running Android Studio altogether (which not only takes a long time to start, it also takes a large amount of harddrive space). It's these long loading times and large amount of harddrive space needed for the programming software itself (Android Studio), that really has kept me from going full throttle into making Android apps, as I really do want to make them.

I don't think Google's own official documentation for compiling Android apps even tells you how to do such commandline-only compilings of apps. So unfortunately, the information I will need will likely be coming from some third party hacker who's managed to use reverse engineering to find the minimum number of needed programs to perform compiling for Android. And Google's official documentation will definitely not be helpful in pointing me to any such third party source of such information. So I hope someone here knows where I can get such information, or even has such information themselves.
