9: Android Bytecode Optimisation with Emma
Play • 42 min

In this episode, Pascal and Mihaela chat with Emma about Redex, an open-source bytecode optimiser for Android apps. Emma talks about the importance and trade-offs of such optimisations and walks us through the basic steps of how Redex works and the different types of detection patterns it uses. If you are interested in trying Redex for yourself or curious to know how it's different than other similar tools, Emma discusses how to adopt Redex in your app and how to write your own detection pattern.
