This is a simple log print utils, likeandroid.util.Log.
The "log" module is written in kotlin and can be used anywhere in Java / Kotlin projects.
- API Documentdokka
The "log-android" module is a utility for using the "log" module on Android.
- API Documentdokka
log
- Java SE 7 or later
log-android
- Android API Level 14 (Android 4.0.0) or later
And I strongly recommend to use with Lambda. (Kotlin, Java8, desugar, retrolambda, etc.)
This library needs to set Log Level. Default is never output log.And needs to specify a Sender. Default does nothing.
If you use the default implementation, write as follows.
privatevalDEBUG=trueprivatevalVERBOSE=true...if (DEBUG) {Logger.setLogLevel(Logger.VERBOSE)Logger.setSender(Senders.create())Senders.appendCaller(VERBOSE)Senders.appendThread(VERBOSE)}
If you write it like this, you can output log to Logcat. (default is System.out)
privatevalVERBOSE=true...if (BuildConfig.DEBUG) {Logger.setLogLevel(Logger.VERBOSE)Logger.setSender(AndroidSenders.create())AndroidSenders.appendCaller(VERBOSE)AndroidSenders.appendThread(VERBOSE)}
Of course you can implement Sender any way.e.g. write to a file or send it to the network, etc.
Logger.setSender {level, message, throwable->...}
If you want to use same format as the default, please try the following:
Logger.setSender(DefaultSender.create { level, tag, message->...})
If you set the log level, logs that are equal to or higher than the set value are output.
ASSERT > ERROR > WARN > INFO > DEBUG > VERBOSE
eg. If you set Log.ERROR
Logger.setLogLevel(Log.ERROR)
Only ASSERT or ERROR level logs are output.
Logger.v("verbose")Logger.d("debug")Logger.i("info")Logger.w("warning")Logger.e("error")
Logger.setLogLevel(Logger.VERBOSE)Logger.setSender(Senders.create())

In 0.9.4 moved to mavenCentral from jcenter.
Please note that thegroupID has changed
Download from mavenCentral.
Add dependencies, as following.
dependencies { implementation("net.mm2d.log:log:0.9.4")}
If use with Android utils, as following.
dependencies { implementation("net.mm2d.log:log:0.9.4") implementation("net.mm2d.log:log-android:0.9.4")}
Versions below 0.9.4 were distributed with jCenter.However, jCenter will close and old versions are not migrated to mavenCentral.If you need an older version, please use the Github Pages repository.
repositories { maven { url=URI("https://ohmae.github.com/maven") }}
dependencies { implementation("net.mm2d:log:0.9.3") implementation("net.mm2d:log-android:0.9.3")}
