#1 about 4 min

The impact of slow Gradle builds and modularization

How modularization helps Gradle compile only necessary changes to reduce daily build times.

#2 about 3 min

Analyzing module relationships and recompilation triggers

Understanding how changes at different levels of a project monolith force downstream module recompilations.

#3 about 3 min

The drawbacks of leaking dependencies with API configurations

Why using API declarations leaks transitive dependencies and forces unnecessary project rebuilds.

#4 about 2 min

Applying single responsibility to commons modules

Preventing frequent, project-wide rebuilds by splitting generic commons logic into specific feature modules.

#5 about 3 min

Splitting large domains and utilizing sample apps

Breaking massive domain modules into smaller pieces and using localized sample apps for faster testing.

#6 about 2 min

Separating public interfaces from implementation details

Extracting stable public APIs from volatile code to minimize the compilation impact of internal changes.

#7 about 4 min

Decoupling features using global navigation systems

Replacing direct module dependencies with centralized navigation graphs and URIs to streamline architecture.

#8 about 6 min

Unifying configurations with custom Gradle convention plugins

Creating shared build logic modules to standardize settings across all Android project submodules.

#9 about 4 min

Managing polyrepo dependencies with version catalogs

Utilizing TOML files and custom settings plugins to harmonize library versions across complex repositories.
