Android應用中執行Linux命令

  修改某一檔案的許可權為777為例：

/** 執行Linux命令，並返回執行結果。 */        public static String exec(String[] args) {            String result = "";            ProcessBuilder processBuilder = new ProcessBuilder(args);            Process process = null;            InputStream errIs = null;            InputStream inIs = null;            try {                ByteArrayOutputStream baos = new ByteArrayOutputStream();                int read = -1;                process = processBuilder.start();                errIs = process.getErrorStream();                while ((read = errIs.read()) != -1) {                    baos.write(read);                }                baos.write('n');                inIs = process.getInputStream();                while ((read = inIs.read()) != -1) {                    baos.write(read);                }                byte[] data = baos.toByteArray();                result = new String(data);            } catch (IOException e) {                e.printStackTrace();            } catch (Exception e) {                e.printStackTrace();            } finally {                try {                    if (errIs != null) {                        errIs.close();                    }                    if (inIs != null) {                        inIs.close();                    }                } catch (IOException e) {                    e.printStackTrace();                }                if (process != null) {                    process.destroy();                }            }            return result;        }  

下面在我們需要的地方調用上面函數即可：

String[] args = { "chmod", "777", "(檔案路徑)"};   exec(args);
