What methods can be used to reduce application startup time?

To reduce the startup time of an Android application, the following methods can be used:

• Code and resource optimization: reduce APK size, remove unused resources.
• Lazy initialization: load heavy components and libraries as needed, not at startup.
• Using Splash Screen: to improve perceived load time.
• Profiling and optimization: use profiling tools (e.g., Android Profiler) to identify bottlenecks.
• Using Instant Run / Apply Changes: speeds up the development cycle but does not affect the final APK.
• Database and network operation optimization: avoid long operations in the onCreate method.
• Using multithreading: perform heavy operations in a background thread.

These methods will help make app startup faster and smoother.
