是否有任何的API，它讲述了一个Android设备是否为双核或不？ [英] Is there any API that tells whether an Android device is dual-core or not?

问题描述

我通过做多线程双核心优化，它的工作原理是这样的： 如果设备具有双核处理器，将创建两个线程完成计算，并且如果装置只有一个核处理器，只有一个线程被创建做计算

I am doing dual core optimization by multi-threading, and it works like this: If the device has dual-core processor, two threads are created to do the computation, and if the device has only one-core processor, only one thread is created to do the computation.

我的问题是：怎么我的程序知道设备是否是双核还是不？ 我只希望有一程序，它可以既双核和一核心设备上运行，因此它必须能够知道的信息。

My question is: how does my program know whether a device is dual-core or not? I just want to have one program that can run on both dual-core and one-core devices, so it has to be able to know that information.

code是这样的：

    if( xxx_API_is_device_dual_core() )  // Inside if() is the expected API
    {
     saveThread = new SaveThread[2];
    }
    else
    {
    saveThread = new SaveThread[1];
    }

非常感谢您的帮助！

Thank you very much for any help!

推荐答案

是的 Runtime.availableProcessors（）未能在2核设备上正确地报告？

Is Runtime.availableProcessors() fails to report correctly on the 2-core device?
