Android Question Using ContentChooser URI, Dir/Filename

[RJB]

Hi,
if I use contentchooser to select a file then I can access the file using the returned URI, Dir/Filename.
If I save those details in a file then try to use them the next time the App is run I get an error:

(SecurityException) java.lang.SecurityException: Permission Denial: opening provider com.android.providers.media.MediaDocumentsProvider from ProcessRecord{4244e500 23518:com.XXXX.XXXX/u0a82} (pid=23518, uid=10082) requires android.permission.MANAGE_DOCUMENTS or android.permission.MANAGE_DOCUMENTS

Can those details be used next time it runs? If so how?
How to set permission: android.permission.MANAGE_DOCUMENTS?
Thanks

the search box is the best thing since b4x pages.

Thanks I'll read through it.
Out of interest what did you put in the search box to find that? It never came up with the combinations I tried.

i typed "android.permission.MANAGE_DOCUMENTS" in the search box. that was the best i could do.

OK thanks. Looks like the easiest and safest thing to do will be to copy the file to SafeDirDefaultExternal then save the new location. I'll try it later.

Yes, that seems to work, something like:

    Class_Globals: Public rpTempDir As String
    B4XPage_Created: rpTempDir = rp.GetSafeDirDefaultExternal("Temp")

........
    Wait For CC_Result (Success As Boolean, Dir As String, FileName As String)
    If Success Then
        Dim FileCount As Int = 0
        Dim CopyFileName As String = "Image" & FileCount & ".jpg"
        Do While File.Exists(B4XPages.MainPage.rpTempDir, CopyFileName)
            FileCount = FileCount + 1
            CopyFileName = "Image" & FileCount & ".jpg"
        Loop
        File.Copy(Dir, FileName, B4XPages.MainPage.rpTempDir, CopyFileName)
........

Now just need to think about how to avoid loads of copied files building up once they are no longer needed!
