I try run bash on android using next code:
    Process proc = null;
    try 
   {
        proc = Runtime.getRuntime().exec("/bin/bash");                      
    } catch (IOException e) 
   {
        e.printStackTrace();
   }
   if (proc != null)
   {
    //some code
   }else
    System.out.println("NULL");
But proc always is null. What I do wrong?
