Control Rig not working on android mobile

I make a Control rig or CR which can do basic foot IK, it works fine on PC simulating, but when install into android mobile device, it cant work, I dont know I should post which part of my blueprint, they just prety basic and meanwhile can work on PC, I dont think BP or CR itself have any major problem. It should be some setting problem or sth else.
If you need any part of my projection’s detail, just let me know
thanks in advance
