[Java] Runtime Exec

The Exec method of runtime is often used to record standard usage and make it easier to copy code later.

Process process; String cmd = "cat/sys/devices/virtual/mxc_edid_class/mxc_edid_dev/timing"; StringBuffer SB =New StringBuffer ("");Try{process = Runtime.getruntime (). EXEC ("su"); String line =Null; DataOutputStream dos =NewDataOutputStream (Process.getoutputstream ()); Dos.writebytes (cmd + "\ n")); Dos.flush (); Dos.writebytes ("exit\n"); Dos.flush (); BufferedReader BF =New BufferedReader (new InputStreamReader (Process.geterrorstream ())); While (line = Bf.readline ()) = null) {} BufferedReader bf2 = new BufferedReader (new InputStream Reader (Process.getinputstream ())); While (line = Bf2.readline ())! = null) {sb.append (line);} process.waitfor ();} Catch (Exception e) {e.printstacktrace (); return;}
