我需要使用线程来测试android中的代码执行速度吗？

public class SpeedTestActivity extends AppCompatActivity {
    private static final int NUM_THREADS = 10;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_speed_test);

        // 创建线程池
        ExecutorService executor = Executors.newFixedThreadPool(NUM_THREADS);

        // 执行测试代码
        for (int i = 0; i < NUM_THREADS; i++) {
            executor.execute(new TestRunnable());
        }

        // 关闭线程池
        executor.shutdown();
    }

    private class TestRunnable implements Runnable {
        @Override
        public void run() {
            // 在这里执行需要测试的代码
            long startTime = System.currentTimeMillis();

            // TODO: 执行需要测试的代码

            long endTime = System.currentTimeMillis();
            long executionTime = endTime - startTime;

            Log.d("SpeedTest", "Execution time: " + executionTime + "ms");
        }
    }
}
