What methods are used to improve the efficiency of the system?

The following methods are used to improve the efficiency of Android applications:

• Memory optimization: avoid memory leaks, use weak references, release resources timely.
• Asynchronous processing: perform heavy operations (network, database, calculations) in a background thread (for example, using AsyncTask, Coroutine, RxJava) to prevent blocking the UI.
• Data caching: store frequently used data in memory or on disk for quick access.
• Network optimization: use compression, minimize the number of requests, apply efficient protocols.
• Using profilers: Android Profiler helps identify bottlenecks in CPU, memory, and network.
• UI rendering optimization: avoid excessive redraws, use ViewHolder in lists.

Example of an asynchronous request using Kotlin Coroutines:

GlobalScope.launch(Dispatchers.IO) {
    val data = fetchDataFromNetwork()
    withContext(Dispatchers.Main) {
        updateUI(data)
    }
}
