How to make Executors backward compatible?

    // Example of creating an ExecutorService that is backward compatible for Android
    ExecutorService executorService;
    
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        // Use modern Executors if Honeycomb and above
        executorService = Executors.newFixedThreadPool(4);
    } else {
        // Fallback to a backward compatible option for older versions
        executorService = Executors.newCachedThreadPool(); // Custom implementation for older Android versions.
    }

    // Now you can use executorService to run tasks
    executorService.execute(new Runnable() {
        @Override
        public void run() {
            // Task to be executed in the background
            doBackgroundTask();
        }
    });

    // Don't forget to shut down the executor when done
    executorService.shutdown();
