I’m having an issue using Bitmovin’s Player SDK for Android. However I don’t see any logs, so I can’t understand what’s happening. Is there an option to enable logs?

Bitmovin Android Player SDK uses [SLF4J](https://www.slf4j.org/) facade API for logging. So the application has to provide a logger implementation of this API to direct the logs to specific output and control the log output levels. A couple of reference implementation are as below.

> Useful logger for Android based on standard android.util.Log class. Simple lightweight (\< 50 Kb) implementation of SLF4J API. Easy but powerful configuration via properties file and some additional helpful logging methods. Easy analogue of popular log4j library.

Quick steps to enable logs using [android-logger](https://github.com/noveogroup/android-logger) are as follows:

1. Add following dependency in your app build.

```auto
dependencies {
  compile 'com.github.tony19:logback-android:2.0.0'
}

```

1. Create app/src/main/assets/logback.xml containing following in your app.

```auto
<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>

```

## Proguard Configuration

When using [Proguard](https://www.guardsquare.com/proguard), the following line must be added to the proguard file:

```auto
-dontwarn org.slf4j.**

```

I know that this has already been answered, but I would like to add a little to this:

While the SLF4J logging facade is currently the official logger in the Android Player SDK it is also very helpful to subscribe to warning and error events on the `Source` and the `Player`:

```auto
        // Attach warning and error listeners to player
        player.on<PlayerEvent.Error> { Log.e("PlayerError", "$it") }
        player.on<PlayerEvent.Warning> { Log.w("PlayerWarning", "$it") }

        // Attach warning and error listeners to source
        source.on<SourceEvent.Error> { Log.e("SourceError", "$it") }
        source.on<SourceEvent.Warning> { Log.w("SourceWarning", "$it") }

```

This can provide you with quick feedback when something is going wrong.
