title: Custom ReleaseTree is not showing the logs using Timber
body: <p>I am using custom <code>ReleaseTree</code> for my application using Timber to filter the logs. But when building the release apk application logs are not showing in logcat. When using <code>Timber.DebugTree()</code> in release build logs are showing properly. </p>
  
  <p>Here is my ReleaseTree class:</p>
  
  <pre><code>class ReleaseTree : Timber.Tree() {
  
      override fun log(priority: Int, tag: String?, message: String, throwable: Throwable?) {
          // Don't log VERBOSE, DEBUG and INFO
          if (priority == Log.VERBOSE) {
              return
          }
  
  
          if (priority == Log.ERROR){
              val t = throwable ?: Exception(message)
  
              // Crashlytics
              Crashlytics.setInt(CRASHLYTICS_KEY_PRIORITY, priority)
              Crashlytics.setString(CRASHLYTICS_KEY_TAG, tag)
              Crashlytics.setString(CRASHLYTICS_KEY_MESSAGE, message)
              Crashlytics.logException(t)
          }
  
      }
  
      companion object {
          private val CRASHLYTICS_KEY_PRIORITY = "Priority"
          private val CRASHLYTICS_KEY_TAG = "Tag"
          private val CRASHLYTICS_KEY_MESSAGE = "Message"
      }
  }
  </code></pre>
  
  <p>How I am initializing the ReleaseTree from Application class:</p>
  
  <pre><code>Fabric.with(this, new Crashlytics());
  Timber.plant(new ReleaseTree());
  </code></pre>
