How can I transfer the binary data obtained by the web end via socket.io to the Android native layer?

I have checked the source code, and it is necessary to transmit strings to the native layer. However, this will affect my efficiency. For the binary stream pushed by socket.io at 30fps, I have to convert it to base64 for transmission, and then convert it back from base64 in the native layer. As a result, from the time-consuming statistics log, I found that the round-trip conversion time for the binary data of each frame fails to meet the expected requirement.
