Android Question [Solved]File I/O and storage confusion.

[DataMiser]

Having some issues with some file routines I am trying to add to my app.

I have this code that saves some data to a file.

Private cfgWriter As TextWriter
cfgWriter.Initialize(File.OpenOutput(File.DirInternal,"Device.cfg",False))
cfgWriter.WriteLine(txtHostIP.text)
cfgWriter.WriteLine(txtPort.Text)
cfgWriter.close

Then I have this code that reads the file

If File.Exists(File.DirInternal, "Device.cfg") Then
Private cfgReader As TextReader
cfgReader.Initialize(File.OpenInput(File.dirinternal,"Device.cfg"))
modCommon.HostIP=cfgReader.ReadLine
modCommon.HostPort=cfgReader.ReadLine
cfgReader.close
Else

The code is reading the data from the file but I can't seem to locate the file on the device if I browse for it from my PC.

I have added a msgbox to display the value of the folder and it shows \data\data\my.app\files. No such folder shows up in explorer. If I look under \android\data\my.app\files there is no file there.

If I switch to DirDefaultExternal or DirRootExternal it shows different paths but also paths that I can not locate on the device.

So the question is where are the files actually being written and why can't I locate them from my PC?
Also is there a way to specify some other path and/or create files that can be accessed from the PC through Windows Explorer.

I am pretty sure that when I was testing with the trial version I had used an example from the guide and the file was written under the \android\data\package,name\files folder and that I was able to see it from the pc, copy it over and look at the contents of it but for some reason I can not seem to locate either of the files being created by my app now yet I know they are being created because the app can read them afterwards.

btw I am testing using a Samsung Tab4 connected via USB to a windows 10 PC

\android\data\package,name\files folder

\android\data\package,name\files folder is DirDefaultExternal in Tab4. I have used a Tab4 and you will be able to see the file using explorer. You may have to unplug and replug the USB cable.

Pulling the USB cable and reconnecting did the trick.

Thanks

Is there a way to write to a specific folder on the device?

For example I have a Temp folder off the root is there a way to write there?

Yes. You can use File.DirRootExternal & "/Temp" instead of file.DirDefaultExternal

Cool, that makes sense. I suppose I was confused by what shows up when I used msgbox to display the content of File.DirRootExternal

Thanks again
