Logger

Simple, pretty and powerful logger for android

Setup

Download

groovy
implementation 'com.orhanobut:logger:2.2.0'

Initialize

java
Logger.addLogAdapter(new AndroidLogAdapter());
And use
java
Logger.d("hello");

Output

Options

Logger.d("debug");
Logger.e("error");
Logger.w("warning");
Logger.v("verbose");
Logger.i("information");
Logger.wtf("What a Terrible Failure");

String format arguments are supported

java
Logger.d("hello %s", "world");

Collections are supported (only available for debug logs)

java
Logger.d(MAP);
Logger.d(SET);
Logger.d(LIST);
Logger.d(ARRAY);

Json and Xml support (output will be in debug level)

java
Logger.json(JSON_CONTENT);
Logger.xml(XML_CONTENT);

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 adapter checks whether the log should be printed or not by checking this function. If you want to disable/hide logs for output, override

isLoggable
method.
true
will print the log message,
false
will ignore it.
java
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

java
Logger.addLogAdapter(new DiskLogAdapter());

Add custom tag to Csv format strategy ```java FormatStrategy formatStrategy = CsvFormatStrategy.newBuilder() .tag("custom") .build();

Logger.addLogAdapter(new DiskLogAdapter(formatStrategy)); ```

How it works

More

  • Use 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
    java
    // 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);
    }
    });
