Hi I'm experimenting with HDMI CEC on a Zidoo X9S. I've checked out the code base at https://github.com/robbi5/instreamer. I've successfully implemented the class: com.realtek.server.RtkHDMIService I would now like to implement the class com.realtek.hardware.RtkCECManager and call its method doOneTouchPlay But when I try to launch the service com.realtek.server.RtkCECService I receive the error: No implementation found for boolean com.realtek.server.RtkCECService.JNI_Init() (tried Java_com_realtek_server_RtkCECService_JNI_1Init and Java_com_realtek_server_RtkCECService_JNI_1Init__) My questions are: 1. Is JNI_Init missing from the default source libraries on the zidoo? 2. If so, is a library that contains JNI_Init available from this forum? 3. Is JNI_Init already present in some library on the zidoo that I am not implementing correctly? 4. Is there a better way for me to implement CEC than using RtkCECService? Thanks
