Read logcat continuously in Android app -

-

i'm trying read continuously - means:

if, example, have process every few second write logcat, want app listen on logcat, once new line added - catch , show on screen

i have 1 activity every second write counter log:

runnable r = new runnable() {      @override     public void run() {         i++;         log.d("bbb", "i= " + i);         mhandler.postdelayed(this, 1000);                    } };

i have service trying "listen" on "logcat -s bbb", once listener started - app stuck (looks app entered endless loop) , after few seconds got message app must closed.

the listener code is: (the message "start read line" printed , that's it...)

public static void parse() {     runtime rt = runtime.getruntime();     process process = null;     try {         process = rt.exec("su");         dataoutputstream os = new dataoutputstream(process.getoutputstream());           os.writebytes("logcat -s bbb");         os.flush();     } catch (ioexception e1) {         e1.printstacktrace();     }      bufferedreader bufferedreader =              new bufferedreader(new inputstreamreader(process.getinputstream()));      string line;     try {         log.d("aaa","start read line");         while ((line = bufferedreader.readline()) != null)         {             log.d("aaa", "line = " + line);         }         log.d("aaa", "finish");     } catch (ioexception e) {         e.printstacktrace();     } }

the service call function parse() once.

someone have idea wrong?

*** edit: found problem - command "logcat -s bbb" should execute rt (process = rt.exec("logcat -s bbb")), , don't need dataoutputstream) thanks!
