Android之應用中執行Linux命令

下面，我以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);
