Android Question Saving a picture

[Stefano Di Chiano]

Hi,
I'm using the following code to save a picture that I previously loaded from gallery:

        Dim out As OutputStream
        If File.Exists(File.DirRootExternal, "Uppeee/profile.jpg") Then
            out = File.OpenOutput(File.DirRootExternal, "Uppeee/profile.jpg", False)
            bmp.WriteToStream(out, 100, "JPEG")
        Else
            File.MakeDir(File.DirRootExternal, "Uppeee")
            out = File.OpenOutput(File.DirRootExternal, "Uppeee/profile.jpg", False)
            bmp.WriteToStream(out, 100, "JPEG")
        End If
        out.Close

but when I run it, I get the following error:

sending message to waiting queue (OnActivityResult)
running waiting messages (1)
Error occurred on line: 196 (Profilo)
java.io.FileNotFoundException: /data/user/0/it.uppeee.uppeee/files/Uppeee/profile.jpg (No such file or directory)

Even if I have the picture in the gallery I need to save it as a profile picture. So the next time the user log in, I can already show the picture without having the user to select it again.
Line 196 is: "out = File.OpenOutput(File.DirInternal, "Uppeee/profile.jpg", False)". I don't get why I get the "No such file or directory" error even if I'm using the MakeDir function just the line before.

Can anyone help me solve this issue?

Are you requesting the "write external storage" permission at runtime? Are you aware to the complexities related to File.DirRootExternal?

Why aren't you using File.DirInternal?

 

[ronell]

use GetSafeDirDefaultExternal

Sub Process_Globals
    Private rp As RuntimePermissions
End Sub

    Dim out As OutputStream
        If File.Exists(rp.GetSafeDirDefaultExternal("Uppeee"), "profile.jpg") Then
            out = File.OpenOutput(rp.GetSafeDirDefaultExternal("Uppeee"), "profile.jpg", False)
            bmp.WriteToStream(out, 100, "JPEG")
        Else
          
            out = File.OpenOutput(rp.GetSafeDirDefaultExternal("Uppeee"), "profile.jpg", False)
            bmp.WriteToStream(out, 100, "JPEG")
        End If
    out.Close

Are you aware to the complexities related to File.DirRootExternal?

No, I am not. Is there a tutorial that explains it?

use GetSafeDirDefaultExternal

I did as you say and it works.

Should I use GetSafeDirDefaultExternal or DirInternal?

Should I use GetSafeDirDefaultExternal or DirInternal?

DirInternal refers to storage that is inside the app's private area. Judging by this statement ...

So the next time the user log in, I can already show the picture without having the user to select it again.

... that is exactly what you need. Using external storage of any type is more complicated and I cannot see how it would give you any benefits. Use DirInternal.

 

[Erel]

Use DirInternal.

 

[Stefano Di Chiano]

Ok, I will use DirInternal then. Thanks for the help!
