after struggling around with the mcte utils settings.ini file to remap buttons, I tought I might share what I learned.
This assumes, you have installed xposed, activated the mtce-utils module and placed the settings.ini file at your internal sc card (/storage/emulated/0).
Here's how to remap buttons:
# In this section, you have to put all GLOABL remap functions into. You can use the following ways or remapping:
# note: xxx always stands for the mtc-keycode. If you do not know them, you can use MTCD Tools -> Creata new bnding -> Obtain key sequence to get the key codes.
#--> this defines to launch any app, e.g. app_257 would in my case launch spotify when pressig OK button.
keycode_xxx = 4
# ---> with the keycode command, you can assign android keycodes. For example "4" is the back button, "87" is media next.
# a full list of android codes can be found here: https://android.googlesource.com/platform/frameworks/native/+/master/include/android/keycodes.h
activity_xxx = com.zoulou.dab/com.zoulou.dab.MainActivity
# --> this is to launch any activity. Always put a pair of app/activity with a slash in between. My example starts the DAB App.
intent_xxx= [any android intent action]
#--> this is to assign an intent. Couldn't test it yet.
# --> this is used to reassign another mtc key.
# to remap buttons within specific apps, create an extra section which contains the app name [B][app.name#keys][/B]
# same as with global remapping, put the codes here as you which to reassign keys within special apps.
Well hope that makes the settings more clear for you.
