Adds a file to the downloads database system, so it could appear in Downloads App (and thus become eligible for management by the Downloads App).

It is helpful to make the file scannable by MediaScanner by setting the param isMediaScannerScannable to true. It makes the file visible in media managing applications such as Gallery App, which could be a useful purpose of using this API.

For applications targeting android.os.Build.VERSION_CODES#Q or above, path must be within directories owned by the application {e.g. Context#getExternalFilesDir(String)} or if the application is running under the legacy storage model (see android:requestLegacyExternalStorage), path can also be within the top-level Downloads directory (as returned by Environment#getExternalStoragePublicDirectory(String) with Environment#DIRECTORY_DOWNLOADS).
