Android的你如何在设备总内存RAM？ [英] Android How do you get total memory RAM in the device?

问题描述

我可以得到总的可用内存：

I can get total available memory by:

ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
MemoryInfo memoryInfo = new ActivityManager.MemoryInfo();
activityManager.getMemoryInfo(memoryInfo);
memoryInfo.availMem;

不过，你怎么弄的设备的总内存（RAM）？

However, how do you get Total memory (RAM) of the device?

我看过： <一href="http://stackoverflow.com/questions/2298208/how-to-discover-memory-usage-of-my-application-in-android">http://stackoverflow.com/questions/2298208/how-to-discover-memory-usage-of-my-application-in-android

它似乎并不像加pidMemoryInfo.getTotalPss（）给我的总内存无论是。

It doesn't seem like adding pidMemoryInfo.getTotalPss() gives me the total memory either.

推荐答案

试试这个对我的作品。

public static String getTotalRAM() {
    RandomAccessFile reader = null;
    String load = null;
    try {
        reader = new RandomAccessFile("/proc/meminfo", "r");
        load = reader.readLine();
    } catch (IOException ex) {
        ex.printStackTrace();
    } finally {
        // Streams.close(reader);
    }
    return load;
}
