Android Question The path to the file when using the soft emulator

[Valeriy Lakhtin]

During initialization drawing or reading a text file on the emulator, I have problems. I suspect that when debugging and testing on an soft emulator, the standard DIR File.DirAssets or File.DirInternal - give errors. So I think in the code is necessary temporarily to print a different path. If I'm right do you can tell me how to describe the standard path to the files when use on the emulator. For me to use the emulator is very convenient so do not need me to discourage use of the emulator

What errors ?

I think File functions works the same way on emulator and real device

Log(File.DirInternal & " DIR")
bitMap.Initialize(File.DirAssets, strIMG)

Eerror rows in log window

/data/user/0/b4a.example/files DIR
java.io.FileNotFoundException: /storage/emulated/0/Android/data/b4a.example/files/virtual_assets/
img_sushi_mal1.png
(No such file or directory)

I checked the file exists in the source directory

remove the space from the " DIR"

DIR not impotent word becouse it is in Log string. I have two parts DirAssets and Imge file nam, togethe they have errors. But example with listview with picture work OK. May be a problem in the file extension from my PNG, or in the size of pictures 150x200

 

[DonManfred]

The problem is in YOUR code! Find the problem and fix it

Eerror rows in log window
/data/user/0/b4a.example/files DIR

I want to get a listView with a picture using data from XML file. I decided to problems with reading XML file. I checked the file name from XML file and checkit it with list files. But I can not activate the image before it is inserted into the list. Maybe me need to copy a picture in other catalog before building the listview. I write my code as Example

Sub xomBuilder1_BuildDone(xomDoc As XOMDocument, Tag As Object)
'   Log(LastException.Message)
   If xomDoc.IsInitialized Then
'   If Not (xomDoc=Null) Then   
'         Msgbox(N_Group,"first test")
        Dim RootElem As XOMElement
        RootElem=xomDoc.RootElement
        xomGroups= RootElem.GetChildElementsByName("group")
        N_Group = xomGroups.Size
'       Msgbox(N_Group & "ALL ОК","second test")
        Dim strIMG As String, strName As String, loc_Rating As String, Rating As String, strData As String
        Dim str1 As String, str2 As String
        Dim i As Int
        Dim bitMap As Bitmap

        Log(N_Group)
        For i=0 To N_Group-1
            Try
            ' Задаем рисунок для списка
'            Log(xomGroups.GetElement(i).Value & "Группы")
            xomGroup=xomGroups.GetElement(i)
'            Log(xomGroup.Value & "Группа" )
            xomOption=xomGroup.GetFirstChildElementByName("option")
'            Log(xomOption.Value & "Опции")
            ' Формируем имя группы с рейтингом
            strName=xomGroup.GetFirstChildElementByName("name").Value
            str1=loc_Rating & " " & Rating & " " & strName
            Log(Rating & "Рейтинг")
            strData=xomGroup.GetFirstChildElementByName("time").Value
            str2=strData
            Log(strName & "Имя")
            loc_Rating=xomGroup.GetFirstChildElementByName("loc_rating").Value
            Log(loc_Rating & "Лок рейтинг")
            Rating=xomGroup.GetFirstChildElementByName("rating").Value
           
            strIMG=xomOption.GetFirstChildElementByName("beg_img").Value
            Log(strIMG & "Картинка")
            Log(File.DirAssets & "Каталог")
            bitMap.Initialize(File.DirAssets,  strIMG)
        listView_G.SingleLineLayout.Label.TextSize = 20
        listView_G.SingleLineLayout.Label.TextColor = Colors.Blue
        listView_G.SingleLineLayout.Label.Gravity = Gravity.CENTER
        listView_G.FastScrollEnabled = True
            listView_G.AddTwoLinesAndBitmap(str1, str2, bitMap)  
            Catch 
            Log(LastException.Message)   
            End Try       
            Next
        Else
        Msgbox("Проблемы с файлом","")   
    End If
End Sub

There are no problems with the emulator file system.

Have you added the file: img_sushi_mal1.png to the Files tab?

Does it only happen on the emulator?

Try to uninstall the app before you install it.
