Android以编程方式获取SD卡的ID

作者:互联网

有什么方法可以通过编程方式获取Android设备中当前SD卡的某些特定标识符/序列号?

解决方法:

是的,请尝试以下操作:

public String getSDCARDiD()
    {
        String sd_cid = null;
        try {

            File file = new File("/sys/block/mmcblk1");
            String memBlk;
            if (file.exists() && file.isDirectory()) {

                memBlk = "mmcblk1";
            } else {
                //System.out.println("not a directory");
                memBlk = "mmcblk0";
            }

            Process cmd = Runtime.getRuntime().exec("cat /sys/block/"+memBlk+"/device/cid");
            BufferedReader br = new BufferedReader(new InputStreamReader(cmd.getInputStream()));
            sd_cid = br.readLine();
            //System.out.println(sd_cid);

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return sd_cid;
    }
