logcat

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
