Get image from camera-CodePudding

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

How do I fix this error? What am I missing?

CodePudding user response：

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.
