How to fix the issue with Android ImageView not displaying photos.

If the ImageView in Android is not displaying the photo, it could be caused by the following reasons:

1. Photo path is incorrect: Make sure that the photo path you have set is correct, you can try using an absolute path or a relative path to load the photos.
2. The image failed to load: This could be due to a damaged photo file or an unsupported format. Try using a different photo to confirm if the issue is with the image itself.
3. If the size of the image exceeds the limit, it may cause the image to not be displayed properly on the ImageView control. You can try adjusting the size of the image or using the ScaleType property to fit the image.
4. Permission issue: If you are loading photos from the gallery or SD card, add storage read permission in AndroidManifest.xml.
5. Insufficient memory: If there isn’t enough memory on your phone, it could prevent the ImageView from displaying photos. Try clearing the phone’s memory or restarting the application.

If none of the above methods work, you can try restarting your phone or rebuilding the ImageView to attempt to solve the issue.
