Android Question opening file attachment from gmail client

[Branko Milosevic]

my app successfully registers a custom type file (.imp) and it's registered as one of the apps that can deal with this type of file. G-mail in fact skips the options and opens my app directly.

I am also catching the intent in my activity with this code:

Sub Activity_Resume
  
    Dim i As Intent
    i = Activity.GetStartingIntent
  
    If  i.Action.Contains("VIEW") Then
  
            Log(i.GetData)
      
    End If

End Sub

When I click on the file (with my custom extension) in the File Manager app, my app starts and the log(i.GetData) prints the file URI as:

file:///sdcard/impromptu/example%203.imp

However from g-mail the log(i.GetData) does not show a unique file name. This is the log:

content://gmail-ls/[email protected]/messages/29/attachments/0.1/BEST/false

I obviously need some other way to access the attached file but so far haven't been able to find any.

Thanks a lot if you can help...

OK I have a working solution here:

Dim i As Intent
    i = Activity.GetStartingIntent
   
    If  i.Action.Contains("VIEW") Then
   
        Dim jo As JavaObject
        Dim ContentDir As String = jo.InitializeStatic("anywheresoftware.b4a.objects.streams.File").GetField("ContentDir")
        Dim strUri As String = i.GetData

        Dim Inp As InputStream  = File.OpenInput(ContentDir , strUri)
        Dim Out As OutputStream = File.OpenOutput(File.DirRootExternal&"/impromptu", "testfile.imp", False)

        File.copy2(Inp, Out)
        Inp.Close
        Out.Close
   
    End If

However this does not retrieve the original file name and copies the file in the "testfile.imp" file. If I don't figure this out I am may have to implement a sort of a unique file name generator or pop an input dialog to the user to name the file.

Note that you can use "ContentDir" instead of the JavaObject code: https://www.b4x.com/android/forum/threads/receiving-shared-images-from-other-apps.81041/#content

If the file name is not included in the intent then it is not available. Maybe it is stored in a different key. Log the intent and the extras.

Would intent action "SEND" instead of "VIEW" make a difference?

How to get extras? I am not at the computer with b4a at the moment but thinking i.GetExtras would do?

I don't think that it will work with SEND.

How to get extras?

Start with:

Log(i)
Log(i.ExtrasToString)

 

[Branko Milosevic]

No extras. Am I missing some permissions to allow the intent to pass more data?
