I modify the example from Android SDK example so user can add and save contact person details in phone, while introducing a new photo entity called “geotag photo”. User are given two options (gallery or camera) to import image.
BUT the apps crash when user select image from gallery, ALSO if user taking a photo.
below is my class:
