Question Joying UIS broadcast receiver messages in android program

[spdri]

Hello,

I have an earlier developed program with these content:

public final static String MTCBroadcastVolChanged = "com.microntek.VOLUME_CHANGED";
public final static String MTCBroadcastVideosignalChange = "com.microntek.videosignalchange";
public final static String MTCBroadcastBackviewend = "com.microntek.backviewend";

On new joying hu the com.microntek doesn't work. What should I replace with these to get it work on joing uis head unit?

Thanks
