For each Android build, Appcircle creates a brand new virtual machine running Debian Linux (v. 10).
Virtual machines are created and they become ready for build within seconds.
During the build process, you can install any dependencies and run commands using custom scrip steps in the build workflow. This gives you complete control over your build and the virtual machine.
Appcircle supports using a 3rd party computer to perform builds. You can create your own build environment by installing the operating system and other tools and dependencies you need and tell Appcircle to use that environment to perform builds.
There are many pre-installed packages in virtual machines. You can get a full list of pre-installed packages by running Bash commands in custom script steps.
Here are some most important packages installed in our Linux images used for Android builds:
