枚举安装在Android手机上的SD卡

Question

如何从Java或本地代码中枚举安装在Android手机上的所有SD卡？

Answer 1

这不仅会列出挂载的SD卡，还会列出Android设备上的所有挂载的文件系统。

Runtime rt = Runtime.getRuntime(); 
Process proc = rt.exec("cat /proc/mounts"); 
BufferedReader stdInput = new BufferedReader(new 
    InputStreamReader(proc.getInputStream())); 
BufferedReader stdError = new BufferedReader(new 
    InputStreamReader(proc.getErrorStream())); 
// read the output from the command 
while ((s = stdInput.readLine()) != null) { 
    System.out.println(s); 
}
