How to increase performance and test Android performance?

chat GPT:

1. Optimize Layouts and UI Rendering:
   Use ConstraintLayout: Instead of deeply nested layouts, use ConstraintLayout for better performance.
   Reduce Overdraw: Minimize layers of views to reduce overdraw, where pixels are drawn multiple times in a single frame.
   Avoid Unnecessary Views: Only include views that are necessary. Use ViewStub or include tags for layouts that are not always needed.
2. Optimize Background Processes:
   Use WorkManager, JobScheduler, or Coroutines: For managing background tasks efficiently.
   Avoid Frequent Wakeups: Limit how often your app wakes up the device, as this can drain battery and reduce performance.
   Lazy Loading: Load data and resources only when they are needed.
3. Memory Management:
   Avoid Memory Leaks: Use tools like Android Studio Profiler to detect memory leaks. Ensure you’re not holding references to contexts or views unnecessarily.
   Use Bitmap Efficiently: Use BitmapFactory.Options to downsample images to save memory.
4. Network Optimization:
   Reduce Network Calls: Combine network requests, use efficient data formats (e.g., JSON over XML), and use caching where possible.
   Use a Background Thread for Network Calls: Ensure network operations are not running on the main thread to avoid ANR (Application Not Responding) errors.
5. Code Optimization:
   Avoid Unnecessary Object Creation: Reuse objects where possible.
   Use Efficient Data Structures: Choose the right data structures (e.g., SparseArray instead of HashMap when possible).
   Reduce Method Count: Use ProGuard/R8 to reduce method count and optimize bytecode.
6. Profiling and Performance Testing Tools:
   Android Profiler: Use the Android Studio Profiler to monitor CPU, memory, network, and energy usage.
   Systrace: Provides a detailed report on your app's performance, including rendering performance and background work.
   GPU Rendering Profile: Analyze the GPU rendering performance to identify bottlenecks.
   Lint Tool: Run Lint checks to identify potential performance issues.
   LeakCanary: A memory leak detection library for Android.
   StrictMode: Helps detect things you might be doing by accident that could lead to poor performance, like doing disk or network operations on the main thread.
7. Benchmarking:
   Jetpack Benchmark Library: Measure the performance of your Android code, especially useful for testing the speed of operations.
   Macrobenchmark: For measuring startup times, frame rates, and more across the entire app lifecycle.
8. Testing on Real Devices:
   Test on Multiple Devices: Ensure to test on a variety of devices with different performance capabilities.
   Automated Testing: Use Espresso or UI Automator for automated UI tests to ensure performance consistency.
9. Reduce APK Size:
   ProGuard/R8: Minimize and obfuscate your code.
   Shrink Resources: Remove unused resources during the build process.
   Use App Bundles: Google Play App Bundles allow for dynamic delivery of resources, reducing APK size.
10. Monitoring Performance in Production:
    Firebase Performance Monitoring: Helps monitor performance issues in real-time as your app is used by real users.
    Crashlytics: Detect crashes and performance issues with logs and stack traces.
