fetchBase64File

Fetches a file from the given URL and returns its contents as a base64-encoded string.

This is typically used to download a file that was previously uploaded via uploadBase64File. The URL is the one returned by that upload method. The raw response bytes are read in full and encoded to a Base64 string.

The download itself is asynchronous, with the listener callbacks invoked on the main thread. A call rejected on the spot — meeting not joined, or a missing argument — calls listener.onError synchronously on the calling thread.

Requires a joined meeting, like uploadBase64File. Called before the meeting is joined, or while it is reconnecting, nothing is fetched and the reason arrives twice: once on onError (see Meeting for the codes) and once as the same text on listener.onError.

Code Example:

meeting.fetchBase64File(fileUrl, token,
    new TaskCompletionListener<String, String>() {
        
        public void onComplete(String base64Data) {
            Log.d("Meeting", "File fetched, length: " + base64Data.length());
        }

        
        public void onError(String error) {
            Log.e("Meeting", "Fetch error: " + error);
        }
    });
