Android Question Need to read files from another tablet.

Is it feasible to copy the files over a wi-fi connection?

Yes. See this example: http://www.b4x.com/android/forum/th...eceive-files-with-asyncstreams.30493/#content

Erel,
I tried the FileTransfer app on a tablet that has both Wi-Fi and Bluetooth capabilities but using wi-fi it fails on a "Connection Refused" error. The IP address I plugged in for Wi-Fi was the address of the tablet I was trying to get the file from. Is there something I need to do on the tablet I'm trying to read? Is it failing a password test on my router?

Also, on another issue, I tried the transfer app on a tablet that does not have BlueTooth capability and it fails to run on this line:


It gets an error on line 52, "NullPointerException"

I assume, if I want to use that tablet as the reader, I can work around this by deleting all references to BlueTooth in the FileTransfer app's code.

That's correct.

Have you run this app on both tablets?

Erel,
I had not successfully run it on both tablets. In its initial state the BlueTooth logic would fail on the tablet that did not have BlueTooth capability. I was able to comment out all references to BlueTooth in the code and install it and run it on both tablets successfully.

However, it appears that the transfer "pushes" the files to the other tablet rather than "pull" the files. If this is true and the only way this will work, the problem is that I have to sit at each of the six "satellite" tablets one at a time and push the files to the "Master" tablet. I was hoping I wouldn't have to do all that running around. Actually, I was hoping all I had to do was just turn on the other tablets. However, I suppose my ideal would cause all kinds of security issues.

Thanks for your help, though. This is a great transfer tool and remarkably fast. I will keep using it for a while to see if it is really better than the USB connection method. One plus is I won't need to lug a laptop around but then they're getting smaller, too.

One more question. You say "The folder can be changed by setting the StreamFolder field" but I don't know where that is. I don't find that name in the FileTransfer code.

Erel,
Forgive me. I said I couldn't find StreamFolder but now I have. Thanks for not scolding me, as it was right under my nose.
