Advanced
FormatStrategy formatStrategy = PrettyFormatStrategy.newBuilder()
.showThreadInfo(false) // (Optional) Whether to show thread info or not. Default true
.methodCount(0)
// (Optional) How many method line to show. Default 2
.methodOffset(7)
// (Optional) Hides internal method calls up to offset. Default 5
.logStrategy(customLog) // (Optional) Changes the log strategy to print out. Default LogCat
.tag("My custom tag")
// (Optional) Global tag for every log. Default PRETTY_LOGGER
.build();
Logger.addLogAdapter(new AndroidLogAdapter(formatStrategy));
Loggable
Log adapters checks whether the log should be printed out or not by checking this function. If you want to disable/hide logs for output, override isLoggable method and put the condition.
Logger.addLogAdapter(new AndroidLogAdapter() {
@Override public boolean isLoggable(int priority, String tag) {
return BuildConfig.DEBUG;
}
}
);
Save logs to the file
//TODO: More information will be added later
Logger.addLogAdapter(new DiskLogAdapter());
Add custom tag to Csv format strategy
FormatStrategy formatStrategy = CsvFormatStrategy.newBuilder()
.tag("custom")
.build();
Logger.addLogAdapter(new DiskLogAdapter(formatStrategy));
How it works
More
- Use the filter for a better result. PRETTY_LOGGER or your custom tag
- Make sure that wrap option is disabled
- You can also simplify output by changing settings.
- Timber Integration
// Set methodOffset to 5 in order to hide internal method calls Timber.plant(new Timber.DebugTree() {
@Override protected void log(int priority, String tag, String message, Throwable t) {
Logger.log(priority, tag, message, t);
}
}
);
Breaking changes
- Initialization is changed. No backward compatibility support. Use
Logger.addLogAdapter - LogLevel is removed. Use the new
isLoggableapproach
