Android Question Best Method to Transfer Data/files

[JonRubin]

After some searching, I see that there are at least 2 different methods to send data back and forth to a PC. The Websocket Library and the AsyncStreams. However, both seem to be a few years old. My question is which is the best method/library to transfer the data... or is there something newer that I missed in my searches. Thank you for all your help and Happy Holidays to All.

Let me add that the connection between the PC and the Android will be via the Internet and not a USB connection...... Thanks... Jon

Thank you for your reply Mario and I often use FTP however I believe that the functions I am looking for really calls for more of a Websocket or Async approach.... Jon

WebSocket is text based so it is less suitable for file transfers.

There are many ways to transfer files. You can create a small B4J server that receives files: https://www.b4x.com/android/forum/t...r-b4j-server-over-the-internet.37201/#content
You can use sockets: https://www.b4x.com/android/forum/threads/network-asyncstreams-b4xserializator.72149/#content
You can use MQTT.
You can use FTP.
You can use Bluetooth with AsycnStreams and B4XSerializator.

And there are probably more options available.

You can use MQTT.

MQTT? I thought it was ideal for small amounts of data to be sent.

The messages can be large. The maximum size is 250mb. However I wouldn't use it for such large files as the complete message is stored in memory.

The OP didn't write anything about the file size, assuming that it is up to several MBs then MQTT can be a good solution.

Sorry Erel and thank you for your reply.... I'll be transferring JPG's mostly under 1MB. I don't feel that I will be exceeding 250MB. The same file will be simultaneously transferred to multiple Android users Additionally on the the PC Side I will be developing in .net
Thank you! Jon
