I am trying to get an image from the camera on an Android device. I want to display the image in an ImageView. I have a button in a fragment that opens the camera. I use the Activity Results API to get the response. Here's the fragment code:
class MainFragment : Fragment() {
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
val view = inflater.inflate(R.layout.fragment_main, container, false)
val activity = requireActivity()
val file = File(activity.filesDir,"images/go_capture.png")
val imageUri = FileProvider.getUriForFile(
activity,
BuildConfig.APPLICATION_ID + ".images.provider",
file
)
val takePicture = registerForActivityResult(ActivityResultContracts.TakePicture()) { saved: Boolean ->
Log.d(MainFragment::class.toString(), "take picture result")
Log.d(MainFragment::class.toString(), saved.toString())
val action = MainFragmentDirections.actionImage(imageUri.toString())
view.findNavController().navigate(action)
}
val cameraButton: ImageButton = view.findViewById(R.id.camera_button)
cameraButton.setOnClickListener {
takePicture.launch(imageUri)
}
return view
}
}
When I click on the button and take a picture, I get the following exception
Unable to open content: content://codeguru.cameraexample.images.provider/images/go_capture.png

How do I fix this error? What am I missing?
FileProvider will not create directories for you, even though it will create files for you in a designated directory. So, you should make sure that the directory for your file exists before anything tries using a Uri from FileProvider for that file.
