Hi, Facing an screen freeze issue before first activity. As MainApplication uses LoggerFactory.getLogger($class). This method if called first time checks for if StaticLoggerBinder comes from two locations. That takes 200-600 inclusive CPU Time depending on the device used. I have given a stab at solving this problem, i'll be humble if u could review the change. http://jira.qos.ch/browse/SLF4J-328 Regards, Nitin Verms
