android實現自動關機代碼

[java]   private void shutdown() {               try {                   Process process = Runtime.getRuntime().exec("su");                   DataOutputStream out = new DataOutputStream(                           process.getOutputStream());                   out.writeBytes("reboot -p\n");                   out.writeBytes("exit\n");                   out.flush();               } catch (IOException e) {                   e.printStackTrace();               }           }     private void shutdown() { try { Process process = Runtime.getRuntime().exec("su"); DataOutputStream out = new DataOutputStream( process.getOutputStream()); out.writeBytes("reboot -p\n"); out.writeBytes("exit\n"); out.flush(); } catch (IOException e) { e.printStackTrace(); } }Note:手機必須獲取Root權限！！！
