Android Wear - code to read LogCat output programmatically and continuously is not working -

-

hi wrote code read logcat output continuously within background thread started background service in app. not think there errors in code it's not working.

in thread, have:

@override public void run() {     process process = null;     string cmd = "logcat -v time | grep 'audiofocus  requestaudiofocus()'";      try {         process = runtime.getruntime().exec("su");         dataoutputstream os = new dataoutputstream(process.getoutputstream());         os.writebytes("logcat -c" + "\n");         os.writebytes(cmd + "\n");         os.flush();     } catch(exception e) {     }      bufferedreader reader = new bufferedreader(new inputstreamreader(process.getinputstream()));      string line;      try {         while ( (line = reader.readline()) != null ) {             log.e(staticval.tag, line);              // code write line own log file         }     } catch(exception e) {     } }

i added permission manifest:

<uses-permission android:name="android.permission.read_logs" />

however, when plug device pc , test android studio, log.e(staticval.tag, line); did not print out results , nothing wrote own log file.

any appreciated!

(directly run logcat -v time | grep 'audiofocus requestaudiofocus()' on device through adb terminal results expected)
