合法的linux命令，可以從Android應用程序調用它們？

Question

我需要從本地方法C++，這是iwconfig，也使用popen來獲取此命令的輸出的命令。

這是我的代碼

std::string exec(const char* cmd) { 
FILE* pipe = popen(cmd, "r"); 
if (!pipe) return "ERROR"; 
char buffer[128]; 
std::string result = ""; 
while(!feof(pipe)) { 
    if(fgets(buffer, 128, pipe) != NULL) 
    result += buffer; 
    } 
    pclose(pipe); 
    return result; 
} 

我不知道是否有可能把它！

，所以我有這樣的代碼在此link

把「iwconfig的」 shell腳本里面，你可以從機器人，加工標準輸出，直到對其做運行過程中直接..這樣品執行殼名= /斌/ pars_submit。

 public String getFfmpeg(@QueryParam("infil1") String infil1, 
       @QueryParam("infil2") String infil2, @QueryParam("otfil") String otfil, 
       @QueryParam("t") String time) {   
     String outfil = "dummy.mp4"; 

      List<String> command = new ArrayList<String>(); 
      command.add("vendor/bin/pars_submit"); 

      command.add(infil1);  

      command.add(infil2); 
      command.add(otfil); 
      command.add(time); 

System.out.println("Starting process " +command.toString()); 
      ProcessBuilder builder = new ProcessBuilder(command); 
      Map<String, String> environ = builder.environment(); 
//   for(Entry<String, String> entry : environ.entrySet()){ 
    //   System.out.println("ENV " +entry.getKey() + " " +entry.getValue()); 
     //  } 
//   builder.redirectErrorStream(true); 
      Process process = null; 
      try { 
       process = builder.start(); 

      InputStream is = process.getInputStream(); 

      InputStreamReader isr = new InputStreamReader(is); 
      BufferedReader br = new BufferedReader(isr); 
      String line; 
      while ((line = br.readLine()) != null) { 
       //System.out.println(line); 
       outfil=line; 
      } 

//   int exitVal = process.waitFor(); 
//   System.out.println("Process exitValue: " + exitVal); 
      } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
      finally { 
        if (process != null) { 
        process.destroy(); 
        process = null; 
        } 


       }   


      return outfil; 


       }
