I am trying to add some ImageView images to Android Activity (ConstraintLayout), on the Android Studio preview screen, it shows the images correctly, but when I run the application on a real device or emulator, it does not display the image.
Below is the code I'm using,
<?xml version="1.0" encoding="utf-8"?>

</android.support.constraint.ConstraintLayout>
Preview the user interface in Android Studio as shown below.
We see that 3 images are displayed here,
But when I run the application on an emulator or on a real device, it does not display any of the three images. Below is a screenshot of the emulator,
- @ Dimen / rates_icon_size value: 36dp
- Three images sizes,
- icon_rates: 87x59 pixels
- icon_schedule: pixels 88x78
- icon_payout: 60x82
