Strictmode using syslog

[andpro]

Does syslog work ok with strict mode. I got this mesg when creating the logger. But no mesg when the mesg is send.
Not done extensive testing so asking if someone has experience with it.
Thanks

It looks like the SyslogAppender in Android's strict mode causes a NetworkOnMainThreadException:

Can this be fixed?

Thanks

Please test this snapshot of logback-android-1.0.6-2. Thanks.

Hi,

I double checked my test and looks like I do not get the Network exception as you do. The server does show the log mesg so the syslog did push the log mesg to server.
I only get violation for disk read at start up which may be ok as it is reading the configuration file.
I also checked with the snapshot and I get the same. Here is my code.

StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
.detectDiskReads().detectDiskWrites().detectNetwork()
.penaltyLog().build());
StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
.detectLeakedSqlLiteObjects().detectLeakedClosableObjects()
.penaltyLog().build());

    super.onCreate(savedInstanceState);
    logger = LoggerFactory.getLogger(SyslogLogbackActivity.class);
    LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();
    StatusPrinter.print(lc);
    setContentView(R.layout.main);
    logger.debug("Hello Test Strict Mode");

config file (space added around >< as the comments is not showing properly.

< configuration debug="true" >
< appender name="SYSLOG" class="ch.qos.logback.classic.net.SyslogAppender" >
< syslogHost>AAA.REMOVED.com
< port>11111
< facility>AUTH
< suffixPattern>[%thread] %logger %msg
</ appender >
< root level="DEBUG" >
< appender-ref ref="SYSLOG" />
</ root >
</ configuration >

Hi,

In the snapshot the syslog does not work. Went back to the last released jar and it works fine on it.
Thanks

[tony19]

Ok, thanks for testing.
