How do you perform performance analysis and identify bottlenecks in systems?

The following approaches are typically used for performance analysis and identifying bottlenecks in Android applications:

• Profiling with Android Profiler in Android Studio: allows tracking CPU, memory, network, and energy usage.
• Using Traceview and Systrace for detailed analysis of calls and execution time.
• Logging and analyzing ANR (Application Not Responding) to identify UI thread blockages.
• Monitoring UI response time and frame rate to assess interface smoothness.
• Using LeakCanary tools to detect memory leaks.

Example: if an app slows down when loading data, CPU Profiler can show which methods take the most time, allowing for optimization.
