2. Why does user uninstalls app?
3. Users are Impatient • 61% - start < 4sec • 49% - Respond < 2sec Intolerant of problems(Uninstalls) • 80% problematic app < 3 times • 53% crashes, freezes or errors • 36% heavy battery usage Blame the mobile app & the company • 55% App responsible • 37% Company’ brand Survey
4. What is App’s Performance? • Use power sparingly. • Start up quickly. • Respond quickly to user interaction. • No choppy animations, & slow rendering • No App Freezing or Crashing
5. Techniques • Proactive ◦ Planning ◦ Measuring ◦ Profiling • Reactive ◦ Monitoring ◦ Debugging
6. Android Profiler Real time data for app's CPU, Memory, and Network activity. Sample-based method tracing helps us to • Time the code execution • Capture heap dumps • View memory allocations • Inspect network-transmitted files
8. CPU Profiler
11. Memory Profiler
14. Techniques for Profiling Memory • Try forced memory leaks • Provoke memory leaks • Smaller the leak, the longer you need to run the app Trigger a memory leak in one of the following ways: • Rotate the device • Switch between your app & another app
15. Network Profiler
18. APK Debug & Analyzer • Insight into the composition of your APK after the build process • Reduce the time you spend debugging issues with DEX files and resources • Help reduce your APK size.
21. Users are reaching for their mobile devices many times a day to use mobile apps. Make sure yours is one of them.
