IntentService使用方法

public class IntentService extends android.app.IntentService{

    //两个方法必须实现，构造方法和onHandleIntent


    /**
     * Creates an IntentService.  Invoked by your subclass's constructor.
     *
     * @param name Used to name the worker thread, important only for debugging.
     */
    public IntentService(String name) {
        //name表示他的线程名称
        super(name);
    }

    //实现异步任务的方法，Activity传过来的intent，数据包含在intent中
    @Override
    protected void onHandleIntent(@Nullable Intent intent) {

    }
}
