Android Question Saving a picture

Hi,
I'm using the following code to save a picture that I previously loaded from gallery:
B4X: 
        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:

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?

use GetSafeDirDefaultExternal

B4X: 
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

Should I use GetSafeDirDefaultExternal or DirInternal?
Click to expand...
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.
