What Is a Sandbox Android Environment?
A sandbox Android environment is an isolated, secure space where you can run apps without affecting your main operating system. Think of it as a digital quarantine zone on your computer or in the cloud. It's perfect for developers testing new apps, security researchers analyzing potential threats, or anyone who wants to try out an app without giving it access to their personal data.
