Delivering Performance in a Blink

This session focuses on how Blinkit optimized app performance at scale, with emphasis on four key areas — app launch time, UI rendering, stability, and network efficiency.

We'll walk through several practical strategies that drove these improvements - including App Startup Optimization, Lightweight TextView, View Caching, pre-warming the OkHttp client, lazy JSON parsing, Wi-Fi location caching and much more.

We'll also introduce Droid Dex - an open-source tool that provides deep insights into device performance across CPU, memory, storage, network, and battery, helping teams make smarter, data-driven optimisation decisions like selectively delivering high-performance features to capable devices.

Together, these initiatives have significantly reduced load times, improved stability, and elevated the overall user experience for millions of Blinkit users.
