android - Is this below code is correct for saving logcat details to a file in eclipse? -

public static void savelogcattofile(context context) {         string filename = "logcat_"+system.currenttimemillis()+".txt";      file outputfile = new file(context.getexternalcachedir(),filename);      @suppresswarnings("unused")      process process = runtime.getruntime().exec("logcat -f "+outputfile.getabsolutepath());   } 

please check above code , me to save logcat details file (permanently), should append after everytime debugging in eclpise.

try

public static void savelogcattofile(context context)     {     try {                 process process = runtime.getruntime().exec("logcat -d");                 bufferedreader bufferedreader = new bufferedreader(new inputstreamreader(process.getinputstream()));                  stringbuilder log = new stringbuilder();                 string line;                 while ((line = bufferedreader.readline()) != null) {                     log.append(line);                 }                  string logfilepath = environment.getexternalstoragedirectory() + file.separator + "logtest.txt";                  file logfile = new file(logfilepath);                 if (!logfile.exists())                     logfile.createnewfile();                  fileoutputstream outstream = new fileoutputstream(logfile, true);                 byte[] buffer = log.tostring().getbytes();                  outstream.write(buffer);                 outstream.close();             } catch (exception ex) {                 ex.printstacktrace();              }     } 

and don't forget mention permissions in manifest file

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

at last check so link writing file on external storage.
