[codenameone-discussions] Re: logfile
The problem though, unless I'm missing something, is in a thread, with an
unhandled crash the code checks isCrashBound,
(CodenameOneThread#handleException) which would be false and so would never
call the newly installed logger (Log.e())
public static void handleException(Throwable err) {
if(Log.isCrashBound()) {
Log.e(err);
Log.sendLog();
}
}

See this post, which includes a snippet that extracts stack traces using a temporary logfile. You can adapt this to capture all the log events - but except for stack traces I think you're better off using a private mechanism to log info. https://groups.google.com/forum/#!searchin/codenameone-discussions/logfile%7Csort:relevance/codenameone-discussions/kCbXGCqmt2o/N6vvLXtECQAJ -- You received this message because you are subscribed to the Google Groups "CodenameOne Discussions" group.

You can file an RFE for that although I'm not sure when we'll get around to it. 3.6 is already overbooked and 3.7 is filling up quickly with tasks. -- You received this message because you are subscribed to the Google Groups "CodenameOne Discussions" group.

[codenameone-discussions] Re: logfile
ok, so I have a situation that requires some flexibility. The tablets are
air gapped so using the "cloud based crash reporting" wont work. We can
use email based reporting (they can save the logfile as a draft and then
send when they are connected)
However the sendlog function is static (not instance based) so I cant
override it. Can the following, or similar, change be made? Or is there
another way to send the log?
public static void sendLog() {
if (instance != null) instance._sendLog();
}
protected void _sendLog() {
current sendLog continues here .

[codenameone-discussions] Re: logfile
I use this code to capture the contents of a log file. Its a bit obscure
because it threads
a needle through the standard codename1 class "Log" to create a temporary
log file.
class LogCapture extends Log
{Log oldLog;
StringWriter myWriter;
LogCapture()
{ oldLog = Log.getInstance();
install(this);
}
protected Writer createWriter() throws IOException
{return(myWriter = new StringWriter());
}
public String dispose()
{
install(oldLog);
return(myWriter.toString());
}
}
then, this code can capture a stack trace as a string
public static String getStackTrace(Throwable t)
{
LogCapture cap = new LogCapture();
Log.e(t);
return cap.dispose();
}
Rather than redirect System.out, I use my own redirectable printer for
debugging
messages. Depending on the situation, I redirect it to a network stream, a
string
builder, or a logging window that's part of my app.

Log.e() prints the stack trace etc. Grabbing system out/err is a bit of a technical challenge across platforms. -- You received this message because you are subscribed to the Google Groups "CodenameOne Discussions" group.

[codenameone-discussions] Re: logfile
I am interested in getting the stacktrace. In my desktop java apps I redirect System.out and Sytem.err uploading to a website I already have, but others might be intersted in that.

I use this for debugging and catching the unexpected from deployed applications. The biggest trick is getting a stack trace (which is also a "pro" feature for no good reason IMO). I can share my code to (1) get stacktraces (2) post them to a web site (3) receive and log them. The particular code I use may not be suitable for everyone, but the general methods ought to be part of any deployed application. -- You received this message because you are subscribed to the Google Groups "CodenameOne Discussions" group.

Not much beyong the javadocs as far as I recall. Our official way for reading is the sendLog() method which we use a lot but it's a pro feature. Writing is just Log.p(),Log.e() where you can just write whatever you want into the log.
