ActivityResultContracts.TakePicture returns "No such file or directory"

In Fragment, I try to capture an image from the camera and use it. I want to do it with ActivityResultContracts.TakePicture() but when I try to use this image after capturing I get:

W/ImageView: Unable to open content: content://com.myniprojects.pixagram/my_images/default_image.jpg
    java.io.FileNotFoundException: open failed: ENOENT (No such file or directory)

I have seen this question ActivityResultContracts.TakePicture() but I don't know what I am doing wrong. Here is everything that I have done:

Following this docks to manifest I added:

<provider
    android:name="androidx.core.content.FileProvider"
    android:authorities="com.myniprojects.pixagram"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths" />
</provider>

and in res/xml I created file file_paths:

<paths>
    <files-path
        name="my_images"
        path="images/" />
</paths>

And in Fragment:

class AddFragment : Fragment(R.layout.fragment_add)
{
    private lateinit var imagePath: File
    private lateinit var newFile: File
    private lateinit var uri: Uri

    override fun onViewCreated(view: View, savedInstanceState: Bundle?)
    {
        super.onViewCreated(view, savedInstanceState)

        //...

        imagePath = File(requireContext().filesDir, "images")
        newFile = File(imagePath, "default_image.jpg")
        uri = getUriForFile(
            requireContext(),
            requireContext().applicationContext.packageName,
            newFile
        )

        binding.butMakeNewImage.setOnClickListener {
            takePicture.launch(uri)
        }
    }

    private val takePicture = registerForActivityResult(ActivityResultContracts.TakePicture()) { isSaved ->
        if (isSaved)
        {
            binding.imgSelected.setImageURI(uri)
        }
    }
}

If it helps this is the full error logact

In docs we can read

An ActivityResultContract to take a picture saving it into the provided content-Uri. Returns true if the image was saved into the given Uri.

So why I get true when after trying to use this image from Uri I get an error?

I finally figured out how to do it. I am not sure but I think that in the question was a problem with File/Uri. Below is a step-by-step solution how to capture an image.

  1. Dependencies:
implementation "androidx.activity:activity-ktx:1.2.0-rc01"
implementation "androidx.fragment:fragment-ktx:1.3.0-rc01"
implementation "com.github.bumptech.glide:glide:4.11.0"
  1. Manifest:
<uses-permission android:name="android.permission.CAMERA" />

<application>
        <provider
            android:name="androidx.core.content.FileProvider"
            android:authorities="${applicationId}.provider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_paths"/>
        </provider>
</application>
  1. res/xml/file_paths.xml (com.example.name should be changed to proper package name)
<paths>
    <external-path name="my_images"
        path="Android/data/com.example.name/files/Pictures" />
</paths

  1. Check if Manifest.permission.CAMERA is granted. If not request permission.

  2. In Fragment create ActivityResultLauncher like this:

private lateinit var uri: Uri

private val takePicture = registerForActivityResult(ActivityResultContracts.TakePicture()) { isSaved ->
    if (isSaved)
    {
        glide
            .load(uri)
            .into(binding.imgSelected)
    }
}
  1. To launch takePicture (e.g. on button click)
binding.butMakeNewImage.setOnClickListener {

    val photoFile = File.createTempFile(
        "IMG_",
        ".jpg",
        requireContext().getExternalFilesDir(Environment.DIRECTORY_PICTURES)
    )

    uri = FileProvider.getUriForFile(
        requireContext(),
        "${requireContext().packageName}.provider",
        photoFile
    )

    takePicture.launch(uri)
}

Tip. If you got the message permission denial on API level below 21, try to do this:

val resultLauncher = registerForActivityResult(
    object : ActivityResultContracts.TakePicture()
    {
        override fun createIntent(
            context: Context,
            input: Uri
        ): Intent
        {
            val intent = super.createIntent(context, input)
            if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP)
            {
                intent.clipData = ClipData.newRawUri("", input)
                intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION or Intent.FLAG_GRANT_READ_URI_PERMISSION)
            }
            return intent
        }
    }) { success ->
    if (success)
    {
        // TODO
    }
}

resultLauncher.launch(photoUri)
