How to Save Logs to File?

Currently, I'm developing an app for the company I work for, a lot of my co-workers use my app, the thing is, some times crashes/errors occur and I have no way of checking the log messages so I'll like to save the log messages in a text file so when an error happens I can check the log file and get a better idea of what is causing the problem.
I don't need the log to be sent to me through e-mail, it is good enough to have the file locally on the phone so I can plug it in my pc and extract the log file.
Currently, this is how I manage my logs:
try {
//stuff...
}
catch (Exception ex) {
Log.e("Error", ex.getMessage());
}
The Log.e("Error", ex.getMessage()); is what I would like to save.

try this :
public void appendLog(String text)
{
File logFile = new File("sdcard/log.file");
if (!logFile.exists())
{
try
{
logFile.createNewFile();
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
try
{
//BufferedWriter for performance, true to set append to file flag
BufferedWriter buf = new BufferedWriter(new FileWriter(logFile, true));
buf.append(text);
buf.newLine();
buf.close();
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
If you do not want to change your app, you can try mmlog tool.
