Pleasant Android + Kotlin logging by DokiDevs. Inspired by Timber + AnkoLogger.

Features

  1. Use different LogProfile for different builds. Similar to how you plant your tree in Timber.
  2. Get subclass name directly like AnkoLogger. You can only get parent class via Timber.
  3. Enable / disable logging at class level via enableClassLog.
  4. Everything is extendable! Customise LogProfile to suit your needs!

Getting Started

Application

In your Application class, create a LogProfile with a unique name and add it to DokiLog.

IMPORTANT: Default LogProfile is suitable for DEBUG purpose only. Do not use it for RELEASE!!

class DemoApplication: Application() {

    override fun onCreate() {
        super.onCreate()

        if (BuildConfig.DEBUG) {
            // Use the default log profile and give it a name, this should be sufficient for most cases.
            DokiLog.addProfile(LogProfile("Debug"))
        } else {
            // You should always customise your LogProfile for release use!! Beware of information leak!!!
        }
    }

}

DokiLog

Similar to AnkoLogger, implements DokiLog interface to your class and start logging!

Default format of log print is {filterTag} - {subClass} | {method}: {message}

open class BaseActivity: AppCompatActivity(), DokiLog {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        v("This is called from BaseActivity")
        // v for VERBOSE, d for DEBUG... etc.
        // Output: Doki - BaseActivity | onCreate: This is called from BaseActivity

        v()
        // Output: Doki - BaseActivity | onCreate: called
        // Empty argument will automatically replace message with 'called'.
        // This is useful for tracking method call sequence.
    }

}

Continuing from above, you can extend BaseActivity and the log will still be printed. Notice that the class name is DemoActivity even though the log for onCreate is called in BaseActivity.

class DemoActivity: BaseActivity() {

    override onResume() {
        v("This is called from DemoActivity")
        // Output:
        // Doki - DemoActivity | onCreate: This is called from BaseActivity
        // Doki - DemoActivity | onResume: This is called from DemoActivity
    }

}

You can disable logging for a specific class by calling

class DemoActivity: BaseActivity() {

    override val enableClassLog: Boolean
        get() = false
    // Set this to FALSE and all logs related to DemoActivity (including those called in BaseActivity)
    // will not be shown. However, if you mark this as FALSE in BaseActivity, and TRUE in DemoActivity,
    // all logs will still be shown. The control lies with the last class which overrides this value.

LogProfile

IMPORTANT: Default LogProfile is suitable for DEBUG purpose only. Do not use it for RELEASE!!

To customise, extend LogProfile. Some main methods to override are as below.

class ReleaseLogProfile: LogProfile("Release") {  // Give it a unique profile name

    init {
        // Give it a new filter tag if you wish to. Default = "Doki"
        // This is useful for filtering in logcat.
        filterTag = "MyAppName"
    }

    // Modify priority for certain devices
    override fun adjustPriority(priority: Int): Int {
        if (Build.MANUFACTURER.equals("huawei", true) ||
            Build.MANUFACTURER.equals("samsung", true)
        ) {
            if (priority == Log.VERBOSE || priority == Log.DEBUG) {
                return Log.INFO
            }
        }
        return priority
    }

    // Only log for ERROR and ASSERT
    override fun isLoggable(priority: Int): Boolean {
        return priority == Log.ERROR || priority == Log.ASSERT
    }

    // Use the parent class name instead of subclass name (as shown in example above)
    override fun getTag(className: String, stackTraceElement: StackTraceElement): String {
        val tag = "$filterTag - ${stackTraceElement.className} | ${stackTraceElement.methodName}"
        if (tag.length <= MAX_TAG_LENGTH || Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            return tag
        }
        return tag.substring(0, MAX_TAG_LENGTH)
    }

}
