摘　　要：异步技术的选用是制约Android应用产品优劣的重要因素之一。目前Android应用开发的重要异步技术主要包括Async Task、Thread Pool、Thread+Handler这三种。针对这三种异步技术在面对短时间内高爆发的场景时的表现,设计了一个Android应用,分别在稳定性、响应速度、资源耗费等指标方面进行了对比实验及综合分析。实验结果表明,在这三种异步技术中,Thread Pool技术的综合表现最优秀。该技术能更好地适应于短时间内与网络进行大量数据交互的情形,并在一个移动OA项目中采用了Thread Pool技术,利用此技术实现了异步下载文件的功能。The selection of asynchronous techniques is an important factor restricting the pros andcons of Android applications. At present, the important asynchronous techniques of Android application development include AsyncTask, ThreadPool and Thread ＋ Handler. Aiming at the performance of these three asynchronous techniques when facing the scene of high outbreak in short period, we designed an Android application, and carried out the contrast experiments and analyses on stability, reaction speed and consumption of resource separately. Experimental result showed that the ThreadPool technique had the best comprehensive performance among three asynchronous techniques. This technique could better adapt to the situation of interacting a large amount of data with network in a short period. In a mobile OA project the ThreadPool technique was adopted, and by using it the function of asynchronous files download was realised.
