Creating file and storing picture taken with and intent in this file - kotlin

Question

I am trying to create a file in a subdirectory of the internal storage and then saving a picture taken with a picture intent in this file. The picture is only supposed to be used once so everytime a new picture is taken the file can be overwritten with the new picture. I have created a file and with the fileprovider i get a URI for the file and try to save the picture herein but this doesn't seem to work.
The manifest.xlm file:
<uses-feature android:name="android.hardware.camera"
android:required="true" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
android:maxSdkVersion="18" />
<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/provider_paths" />
</provider>
The TakePictureFragment containing the method for creating a file and taking the picture:
fun createFileAndIntent() {
//Lav nyt subdirectory i **internal storage**
val dir = File(context?.filesDir, "mydir")
if (!dir.exists()) {
dir.mkdir()
} else dir.delete()
val filePath = File(context?.filesDir, "mydir")
val newFile = File(filePath, "7Kabale.jpg")
if (!newFile.exists() || !newFile.canRead()) throw
IllegalArgumentException("newFile does not exist")
val fileURI = FileProvider.getUriForFile(
requireContext(),
context?.packageName + ".provider",
newFile
)
if (Uri.EMPTY.equals(fileURI)) throw IllegalArgumentException("Uri not found")
val takePictureIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileURI)
startActivity(takePictureIntent)
}
