Android Question "Save As" problem

[Branksey]

I'm trying to use the SaveAs class, and I've created a minimal project to test it, based entirely on Erel's example here: https://www.b4x.com/android/forum/t...list-of-other-related-methods.129897/#content

I'm not using B4XPages so I have used the GetBA code given in the link above.

My project errors in the FileHandler class, in the sub GetBA (line 39) because the variable "cls" has the value [dateutils=null, ion=java.lang.Object@d64f2c6, main=null, starter=null, xuiviewsutils=null], and it does not contain the string "class".

I'm using B4A version 13.10, and I have made the manifest file additions described here: https://www.b4x.com/android/forum/t...e-and-load-external-files.132731/#post-838166

I'm hoping someone can please tell me what is wrong, because I'm stumped. Thanks in anticipation.

Sub Class_Globals
    Private ion As Object
    Type LoadResult (Success As Boolean, Dir As String, FileName As String, RealName As String, Size As Long, Modified As Long, MimeType As String)
End Sub

Public Sub Initialize
End Sub

Public Sub SaveAs (Source As InputStream, MimeType As String, Title As String) As ResumableSub
    Dim intent As Intent
    intent.Initialize("android.intent.action.CREATE_DOCUMENT", "")
    intent.AddCategory("android.intent.category.OPENABLE")
    intent.PutExtra("android.intent.extra.TITLE", Title)
    intent.SetType(MimeType)
    StartActivityForResult(intent)
    Wait For ion_Event (MethodName As String, Args() As Object)
    If -1 = Args(0) Then 'resultCode = RESULT_OK
        Dim result As Intent = Args(1)
        Dim jo As JavaObject = result
        Dim ctxt As JavaObject
        Dim ContentResolver As JavaObject = ctxt.InitializeContext.RunMethodJO("getContentResolver", Null)
        Dim out As OutputStream = ContentResolver.RunMethod("openOutputStream", Array(jo.RunMethod("getData", Null), "wt"))
        File.Copy2(Source, out)
        out.Close
        Return True
    End If
    Return False
End Sub

Private Sub StartActivityForResult(i As Intent)
    Dim jo As JavaObject = GetBA
    ion = jo.CreateEvent("anywheresoftware.b4a.IOnActivityResult", "ion", Null)
    jo.RunMethod("startActivityForResult", Array(ion, i))
End Sub

Sub GetBA As Object
    Dim jo As JavaObject
    Dim cls As String = Me
    cls = cls.SubString("class ".Length)
    jo.InitializeStatic(cls)
    Return jo.GetField("processBA")
End Sub

After more research I found this useful post Problem with "startActivityForResult", and from it I discovered that the solution for me was to replace my GetBA routine with this one:

Private Sub GetBA As Object
    Return Me.As(JavaObject).RunMethod("getBA", Null)
End Sub

Hi Buddy,

I think perhaps you are using b4xpages because the GetBA version to work with B4a default (Non B4xpages is as shown below)

Sub GetBA As Object
    Dim jo As JavaObject
    Dim cls As String = Me
    cls = cls.SubString("class ".Length)
    jo.InitializeStatic(cls)
    Return jo.GetField("processBA")
End Sub

The version you used is meant for b4xpages as Erel rightly stated in his example.

Just fyi so no confusion with users now attempting to use the SaveAs. If I used your version of GetBA it says no such method called GetBA when compiling
