Hi, my name is Shanu Sahadevan, and in this talk, Maximizing Android App Efficiency, Proven Techniques for Seamless Performance Across Devices, I will share practical tips and proven methods to help you make your Android app run faster, use less battery, and work smoothly on all devices. Jetpack Compose and efficient layout strategies can significantly boost performance, reduce lag, and enhance user experience. Jetpack Compose simplifies UI development with a declarative approach, making code cleaner and easier to maintain. It optimizes UI updates by recomposing only necessary parts, improving responsiveness. It also reduces memory usage and recompositions significantly, ensuring smoother performance. With built in state management, Compose delivers high frame rates and fluid user experience. Deep layouts slow down the rendering. By increasing CPU and GPU. Workload ing view can cut rendering times significantly, making the uua faster and more responsive. Efficient resource management helps reduce app size and speed up loading times for a better user experience. Converting PNG and JPG majors to cut file size by up to 55 percentage without losing quality. This reduces APK size, improves download speed, and saves storage with real world cases, showing up to 3MB reduction. Lazy loading defers non essential resources, cutting initial load times by 40%. By loading images and heavy UI components only when needed, apps achieve faster first page render, improving performance on mid range devices. Optimizing app size ensures faster downloads, lower storage use, and better performance. Android app bundles reduce APK size by up to 35 percent by delivering only the necessary code and resources for each device. This results in faster downloads, lower storage use, and higher installation success rates. ProGuard removes unused code, reducing app size by up to 90%. It also optimizes bytecode, enhancing security and improving runtime performance. Efficient memory management prevents leaks and keeps apps running smoothly. Using SparseArray instead of HashMap reduces memory usage by 50 percent by avoiding auto boxing. It's especially effective for large collections. Weak references help prevent memory leaks by allowing cached objects to be garbage collected when needed. This reduces out of memory errors by up to 40 percent in production, improving app stability. Optimizing network usage reduces data consumption and improves app responsiveness. Retrofits built in caching cuts network requests and reduces API response times from 2. 5 seconds to 0. 3 seconds. By reusing valued responses, apps stay responsive and even with poor connectivity. OKHTTP caching with custom interceptors lower data usage and enable offline access. A well configured disk cache balance performance and storage efficiently. When it comes to threading, efficient multi threading keeps apps responsive and smooth during background tasks. Call in coroutines reduce UI thread blocking, ensuring smooth animations, and trends responsiveness during network calls and image processing. Also using Room Database with suspended functions boosts data operation efficiency, enabling seamless pagination, real time updates, and offline caching without affecting frame rates. Optimizing battery usage helps extend device life and improve user experience. Smart week log management cuts battery drain and ensuring background process don't keep device awake unnecessarily. Also, batching network requests and deferring tasks to ideal periods reduce CPU wake up time. Using job scheduler and work manager ensures tasks run only when charging or on Wi Fi. Android Studio Profiler helps identify and fix performance bottlenecks for a smoother app experience. Track real time CPU usage, memory allocation, and thread activity to detect performance issues. Use CPU sampling, heap dumps, and network analysis to find bottlenecks across different devices. Apply Profiler Insights can cut app load times by 40 percent and reduce memory usage by 30%. By implementing the techniques discussed in this presentation, you can significantly improve the performance of your Android apps. This leads to enhancing user satisfaction to a great level. Thank you all for watching my presentation.
