I'm using logcat to log messages in my Android application, and I'd like to be able to access these messages and show them in a TextView in a DialogFragment. The list of messages is very inconsistent and changes each time I open and close the dialog. It shows the full history once, and then the next time it erases, and sometimes it shows some more messages. Is there anything that I can do to show all the messages (for the run) each time I open the dialog? Am I running the process at the wrong time or something? Or should the buffer be handles somewhere else? Thanks. 

```
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.action_view_logs:
            // View Logs MenuItem tapped
            if (logsDialogFragment == null) {
                logsDialogFragment = new LogsDialogFragment();
            }
            logsDialogFragment.show(getFragmentManager(), "dialog");
            return true;
        case R.id.action_exit:
            // Exit MenuItem tapped
            finish();
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

```

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    Log.i(WifiDirectHandler.LOG_TAG, "Viewing Logs");
    AlertDialog.Builder dialogBuilder =  new  AlertDialog.Builder(getActivity())
        .setTitle(getString(R.string.title_logs))

                public void onClick(DialogInterface dialog, int whichButton) {
                    dialog.dismiss();
                }
            }
        );

    LayoutInflater i = getActivity().getLayoutInflater();
    View rootView = i.inflate(R.layout.fragment_logs_dialog, null);

    TextView logTextView = (TextView) rootView.findViewById(R.id.logTextView);
    logTextView.setMovementMethod(new ScrollingMovementMethod());

    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) {
            if (line.contains(WifiDirectHandler.LOG_TAG)){
                // Removes log tag and PID from the log line
                log.append(line.substring(line.indexOf(": ") + 2)).append("\n");
            }
        }
        logTextView.setText(log.toString());
    } catch (IOException e) {
    }

    dialogBuilder.setView(rootView);
    return dialogBuilder.create();
}
}
