Android. issue with logcat with shell and from app -

if adb shell:

logcat -d -v time incall:i *:s 

i :

but in android app:

 public static stringbuilder getlog() {          stringbuilder builder = new stringbuilder();          try {             string[] command = new string[] { "logcat", "-d", "-v", "time", "incall:i *:s" };              process process = runtime.getruntime().exec(command);              bufferedreader bufferedreader = new bufferedreader(                     new inputstreamreader(process.getinputstream()));              string line;             while ((line = bufferedreader.readline()) != null) {                 //if (line.contains(processid)) {                     builder.append(line);                     //code here                     log.e(tag, line);                 //}             }         } catch (ioexception ex) {             log.e(tag, "getlog failed", ex);         }          return builder;     } 

i only:

--------- beginning of system --------- beginning of main 

why? hot logs adb shell?
