Infrastructure Market: Tinder cuts app cold starts by 47% with new R8 Configuration Analyzer
Google's Android Developers Blog published a case study on Tinder's use of the new R8 Configuration Analyzer to optimize its Android app. Tinder had 70% of its codebase unoptimized, carrying 17 DEX files, and unidentified keep rules blocking R8 optimization. By using the analyzer, Tinder identified and refined an over-broad keep rule from an internal library, unlocking R8 optimization. Results included a 47% reduction in slow app cold starts, a 28.98% decrease in download size (from 86.6 MB to 61.5 MB), a reduction in user-perceived ANRs from 0.35% to 0.28%, and a drop from 17 to 11 DEX files. R8 optimization scores improved from 28% to 50%, with ongoing improvements planned. The team integrated optimization monitoring into CI/CD to prevent regressions. The analyzer is integrated into AGP 9.3, with a standalone Gradle task for faster feedback.
Google, a major platform, released a new developer tool (R8 Configuration Analyzer) that enables significant app performance improvements, demonstrated by Tinder's 47% cold start reduction and 28% size decrease, impacting the broader mobile app ecosystem.
