file:///android_asset/ only works for WebView AFAIK.

what is solution?

You can use my StreamProvider, which offers a ContentProvider that can serve a file from assets/.

Or, you can implement your own ContentProvider that can serve the file from assets/.

Or, you can copy the asset to a local file (e.g., in getFilesDir() or getCacheDir()), then use FileProvider to serve that local file.
