Yes thats right.The error is caused by UI string.I looked app->res->values->strings.xml
And there,like this
Quantized_Efficientnet
Float_Efficientnet
Quantized_MobileNet
Float_Mobilenet
Then,i changed like this
QUANTIZED_EFFICIENTNET
FLOAT_EFFICIENTNET
QUANTIZED_MOBILENET
FLOAT_MOBILENET
And problem is solved.Thanks for your opinion
