I am working on this project: TensorFlow Lite image classification Android example application

I run this project on my own phone (xiaomi redmi note 8) on Android Studio (not emulator)

When I run this project on Android Studio, TFL Classify applications gives the following error: application keep stopping.

Then Android Studio gives this error:

I wanted to put the link, but I got an error “Sorry, you can’t include links in your posts.”
So i put like this
Project link :

github.com.tensorflow.examples.tree.master.lite.examples.image_classification.android

Hi @Ugur_Ercelik it seems that the project builds OK to my AS.
Download again the projects from here go to the image_classification/android folder and build it again.

Also check that inside Classifier.java file there is:

/** The model type used for classification. */
  public enum Model {
    FLOAT_MOBILENET,
    QUANTIZED_MOBILENET,
    FLOAT_EFFICIENTNET,
    QUANTIZED_EFFICIENTNET
  }

Best

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
