Optimization of Android apps: ProGuard, D8, R8. The secrets of obfuscation.

Build optimization is the icing on the cake for a mobile app. Hopefully, some tools have been tested and trusted by the community. Unfortunately, optimization is not always taken seriously and given the attention it deserves.

We will:

• determine the place of build optimization in the matter of optimizing the application;
• analyze how the tools that we are used to using in a couple of lines work;
• slightly open the curtain of obfuscation;
• we will become spectators of the arms race. Analyze the comparative analyzes of the creators of ProGuard and R8.

Regardless of experience, every developer will be able to discover something new.
