LoggerFactory tool
===

In `app/build.gradle`, add the following dependencies:

dependencies {
  compile 'org.slf4j:slf4j-api:1.7.25'
  compile 'com.github.tony19:logback-android:2.0.0'
}

Create `app/src/main/assets/logback.xml` containing:

<configuration>
  <appender name="logcat" class="ch.qos.logback.classic.android.LogcatAppender">
    <tagEncoder>
      <pattern>%logger{12}</pattern>
    </tagEncoder>
    <encoder>
      <pattern>[%-20thread] %msg</pattern>
    </encoder>
  </appender>

  <root level="DEBUG">
    <appender-ref ref="logcat" />
  </root>
</configuration>

In class:

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class BasicClass {
    // 若此類別被繼承, 則 this 會是子類別名稱!!
    protected Logger logger = LoggerFactory.getLogger(this.getClass().getSimpleName()); 
}

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class MainActivity extends AppCompatActivity {
    // 若此類別被為一 Activity, 則 this 會是此類別名稱!!
    protected Logger logger = LoggerFactory.getLogger(this.getClass().getSimpleName()); 
}
