[slf4j-user] Problem with SLF4J and Android

[Max Braun]

I put your code in a basic Android project using slf4j-api-1.5.6.jar  
and slf4j-jdk14-1.5.6.jar from openrdf-sesame-2.3-pr1-sdk.zip. The  
error is the same that I got before:

LoggerFactory; to field Lorg/slf4j/impl/StaticLoggerBinder;.SINGLETON
