First, implement a class that conforms to the Logging interface. Below is an example of a logging service that only prints out messages with a log level of Error.

Copy
class ErrorLogger implements Logging {
 @Override
 public void trace(String tag, String message) {}

 @Override
 public void debug(String tag, String message) {}

 @Override
 public void warning(String tag, String message) {}

 @Override
 public void error(String tag, String message) {
  Log.e("ErrorLogger", message);
 }
}
Copied to your clipboard
class ErrorLogger implements Logging {
 @Override
 public void trace(String tag, String message) {}

 @Override
 public void debug(String tag, String message) {}

 @Override
 public void warning(String tag, String message) {}

 @Override
 public void error(String tag, String message) {
  Log.e("ErrorLogger", message);
 }
}

Next, use the setLoggingService API of ServiceProvider to update the logging service used by the SDK.

Copy
ServiceProvider.getInstance().setLoggingService(new ErrorLogger());
Copied to your clipboard
ServiceProvider.getInstance().setLoggingService(new ErrorLogger());

To revert to the default implementation of the LoggingService, you can set the logging service to nil using setLoggingService API.

Copy
ServiceProvider.getInstance().setLoggingService(null);
Copied to your clipboard
ServiceProvider.getInstance().setLoggingService(null);

Swift

First, implement a type that conforms to the Logging protocol, as defined above. Below is an example of a logging service that only prints out messages with a log level of Error.

Copy
class ErrorLogger: Logging {
  func log(level: LogLevel, label: String, message: String) {
    guard level == .error else { return }
    print("\(label): \(message)")
  }
}
Copied to your clipboard
class ErrorLogger: Logging {
  func log(level: LogLevel, label: String, message: String) {
    guard level == .error else { return }
    print("\(label): \(message)")
  }
}

Next, set the loggingService on the shared ServiceProvider used by the SDK.

Copy
ServiceProvider.shared.loggingService = ErrorLogger()
Copied to your clipboard
ServiceProvider.shared.loggingService = ErrorLogger()

To revert to the default implementation of the LoggingService, you can set the loggingService to nil.

Copy
ServiceProvider.shared.loggingService = nil
Copied to your clipboard
ServiceProvider.shared.loggingService = nil
