Although Cydia is one of the few important applications that were available exclusively on the iOS platform, its creator chose to port the idea to AndroidOS launching Cydia Substrate. Practically Cydia Substrate is the Android version of MobileSubstrate from iOS, Saurik already porting Winterboard to Google's platform. Thanks to saurik's software, developers will be able to port tweaks and applications from Cydia to the Android platform, and this will definitely happen.
Substrate makes it easy to modify software, even without the source code, and in a way that allows users to easily choose which changes they want. Developers support this by building their changes as "substrate extensions" that are loaded into all of the processes they want to take control of. By using the provided API to make all changes in memory, multiple developers can safely adapt the same parts of the target program to their purposes.
Although the whole Cydia Substrate project is just at the beginning, it will offer the owners of Android terminals a platform that on iOS is available for tens of millions of iDevices. For now, you can find out more details about the project on WEBSITE saurik and if you have an Android terminal you will benefit from the tweaks from Cydia in the near future.
