FTP Tests via the Emulator

[Bradley James Marks]

All,

I just purchased Basic4Android. I am trying to conducts some FTP tests.

Is it possible to test FTP functions via the emulator? I keep running into problems.

Thanks,
Brad

You should use a real device. I have always had problems with FTP and the emulator.

 

[Erel]

I agree with @margret. If you do want to test with an emulator then try to set PassiveMode to true.

Margret and Erel,

Thanks for the help, I appreciate it.

I added "PassiveMode = True" and FTP.List now works nicely via emulation mode. (One step forward!!!)

I would now like to get "FTP.DownloadFile" to work in emulation mode.

I copied one of the examples in the B4A documentation as shown on the next line.


FTP.DownloadFile("JobControlRecord1.txt" , False , File.DirRootExternal , "B4ADdown.txt")

I am now receiving this error

LastException.Message = java.io.FileNotFoundException: /mnt/sdcard/B4ADdown.txt (Permission denied)

I would guess that the parameter "File.DirRootExternal" is generating the "/mnt/sdcard/" in the path.

I currently do not have access to a real Android device, so my FTP testing is limited to emulation mode.

Is there a way to get FTP.Download to work in emulation mode?

Thanks,
Brad Marks

Have you configured the emulator to have a SD card?

Create a new AVD and make sure that it includes an SD card.

Erel,

Thanks for your assistance.

No, I had not configured the emulator to have a SD card.

I tried to do so and kept receiving an error.

I then did some more digging and stumbled upon the "mksdcard" utility.

I tried this utility as described here
http://developer.android.com/tools/help/mksdcard.html

From a DOS prompt, I keyed in the command as shown on this page.

When I do this, it keeps echoing back to me the "usage" info for the mksdcard utility.

I must be missing something.

Thanks,
Brad

The mksdcard is only required if you want to copy existing data to the sd card. You do not need it in your case.

Which error did you get when you tried to set an AVD with a SD card?

As I previous wrote I recommend you to use a real device. It is easier and more reliable.

Erel,

Thanks for your assistance.

I set up a new AVD with Size=9MiB. When I tried "Start", I received a message "Failed to allocate memory :8"

I then set up another AVD pointing at a file instead of using the "Size" option. When I tried "Start" for this AVD, I received this message "###Warning SD Card File Must be at Least 9mb, ignoring C:\SD.img Failed to allocate Memory :8"

I am currently away from home and do not have access to a real device. We are driving home today and I hope to be able to test with a real device tonight. Still, I can see where it would be handy to be able to test with a virtual device in the future, so I would like to get things working with AVDs.

Thanks again.

Sincerely,
Brad Marks

Try to set the size to 16mb.

 

[Bradley James Marks]

Erel,

I tried 16mb and again received the "Failed to allocate memory error" with the AVD.

However, I am no longer on the road. I am now back at home and have a physical Android device.

My first test with the real device worked perfectly!!!

I am all smiles.

Thanks for all of your help.

Sincerely,
Brad Marks
