Android Question How do I copy a file to an External SDCard

[davepamn]

    Dim sSourceFile As String=SQLLite.oDB.sPrivateDatabaseName
    Dim sDestinationFile As String=SQLLite.oDB.sPrivateDatabaseName
    Dim sDirSource As String=File.DirRootExternal
    Dim sDirTarget As String=File.DirDefaultExternal

    Try

    File.Copy(sDirSource, sSourceFile, sDirTarget, sDestinationFile)
    ToastMessageShow(sDirTarget & sDestinationFile,True)
    Catch
        oError.ShowLastException("Error : BackupDB_Click")
    EndTry

The code is copying my file to the internal SDCard.

I inserted the following directive in my manifest
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Only on Android 4.4+ there is an API in the OS to get the sd card path.

What does the CanInstallToExternalStorage directive do?

I read the article. Can you provide me the code snippet that I should use to access the sdcard directory? It seemed like a application specific directory had to be created like com.b4a.myapp. Is this true? Or does the api create the directory?

CanInstallToExternalStorage

It is not related to the sd card.

The code in the link posted above will return the path to the folder that you can access.
