保存后文件不存在

Question

I am developing simple node manager where user should be able to make a photo for the note. Here's the code for button that starts the camera:

final Intent makePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

PackageManager packageManager = fragment.getActivity().getPackageManager();
Uri uri = FileProvider.getUriForFile(getActivity(), FILE_PROVIDER, mTempPhotoFile);
makePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri);

List<ResolveInfo> cameraActivities = packageManager
        .queryIntentActivities(makePhotoIntent, PackageManager.MATCH_DEFAULT_ONLY);
for (ResolveInfo info : cameraActivities) {
    getActivity().grantUriPermission(info.activityInfo.packageName, uri,
            Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
}

startActivityForResult(makePhotoIntent, REQUEST_PHOTO);

I'm creating the File object this way:

public File getPhotoFile(String fileName) {
    File filesDir = context.getFilesDir();
    return new File(filesDir, fileName);
}

Here's the FileProvider configuration:

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="com.artyom.taskmanager.fileprovider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/files" />
</provider>
<paths>
    <files-path
        name="task_photos"
        path="."/>
</paths>

After making a photo I set it to ImageView and it is displaying properly. Then the photo file name is set to the field of the note and note is saving to local database using Room.

But when I open saved note the photo is not displaying. I got the photo file by the name from the note's field but file.exists() returns false.

Where I am going wrong I am not able to figure that out. Please help.
