Androidアプリケーション（IDE Eclipse）でログバック付きのslf4jを使用したい。Eclipseでパスをビルドするためにjarファイル（slf4j-api-1.7.1 logback-android-1.0.7-1.jar）をすでに追加しました。次の簡単なメインアクティビティを使用して、Advでアプリを起動しようとしています
import org.slf4j.Logger
import org.slf4j.LoggerFactory
public class MainActivity extends Activity{
private static final Logger logger =
LoggerFactory.getLogger(MainActivity.class);
private void onnCreate(Bundle svedInstanceState){
super.onCreate(savedInstanceState)
logger.debug("MainActivity created");
}
}
そして、logcatによってキャプチャされた次のエラーが発生します
