枚舉安裝在Android手機上的SD卡

Question

如何從Java或本地代碼中枚舉安裝在Android手機上的所有SD卡？

Answer 1

這不僅會列出掛載的SD卡，還會列出Android設備上的所有掛載的文件系統。

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); 
}
