Reverse Engineering of Android Apps


It is not uncommon that you find an amazing Android app on Google Play store and wish to know how the app is designed and developed.

Instead of just storing values as simple strings, it recognizes multiple specific data types such as Lists, Sets, Hashes (maps), Strings or Numbers. Each data type has its own set of features to manipulate the data it contains in an atomic manner, making it an ideal tool for highly distributed system where concurrency is a potential issue.

Combining those features in creative ways allows for novel ways of doing “traditional” things differently.
