如何在安卓Q中将文件从app专用文件夹( file :// scheme)拷贝到MediaStore图片集(content:// scheme)？

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

<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <files-path name="my_images" path="images/"/>
</paths>

File file = new File(getFilesDir(), "images/my_image.jpg");
Uri fileUri = FileProvider.getUriForFile(this, "com.example.myapp.fileprovider", file);

ContentResolver resolver = getContentResolver();
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.DISPLAY_NAME, "my_image.jpg");
values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
values.put(MediaStore.Images.Media.RELATIVE_PATH, Environment.DIRECTORY_PICTURES);
Uri imageUri = resolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

try {
    OutputStream outputStream = resolver.openOutputStream(imageUri);
    InputStream inputStream = getContentResolver().openInputStream(fileUri);
    byte[] buffer = new byte[1024];
    int bytesRead;
    while ((bytesRead = inputStream.read(buffer)) != -1) {
        outputStream.write(buffer, 0, bytesRead);
    }
    outputStream.close();
    inputStream.close();
} catch (IOException e) {
    e.printStackTrace();
}
