处理命令“arp -a”在Android上？ [英] Process command "arp -a" on android?

问题描述

我正在尝试在我的Android设备上调用arp -a，但由于它只适用于PC - 我该如何更改？有没有办法访问一个IP地址列表，arp -a给你，但在Android上呢？

I'm trying to call "arp -a" on my android device, but since it only works for pc - how do i change this? Is there a way to access a list of the ip-addresses, that arp -a gives you, but on android instead?

我的代码在android设备上是这样的：

My code is like this on the android device:

try {

        Process process = Runtime.getRuntime().exec("arp -a");
        process.waitFor();
        BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
        int i = 0;
        while (reader.ready()) {
            i++;
            String ip = reader.readLine();
            if (i >= 4) {
                ip = ip.substring(2, 15) + "\n";
            }
        }
    } catch (IOException | InterruptedException ioe) {
        ioe.printStackTrace();
    }
