HTTP Post a picture using share button.

[arr0ba]

I'm trying to use the share button after taking a picture with camera to upload a picture to a web server that is hosting an asp page. The problem is that I cant seem to get the file name to the image created by the camera after the picture is taken. I am not using the Advanced Camera Library, I want to do this using the native camera app.

In java I was doing this like this

 Uri uri = (Uri) extras.getParcelable(Intent.EXTRA_STREAM);
                         String ImageFile = getRealPathFromURI(uri);

I am stuck here...

How do you access this intent? Where does it come from?

 

[arr0ba]

Its the sharing intent fired when you hit the share button after you take the picture with the camera.

android.content.Intent.ACTION_SEND

Something like:

Dim uri as Object
uri = intent.GetExtra("android.intent.extra.STREAM")

I guess that getRealPathFromUri is the same code as the one posted in post #3 here: http://www.b4x.com/forum/basic4andr...orials/13473-uri-content-media-real-file.html

 

[arr0ba]

The following code returns null every time...

Sub Activity_Resume
ShareIntent = Activity.GetStartingIntent
ToastMessageShow(ShareIntent.Action,False)
   If ShareIntent.Action = "android.intent.action.SEND" Then
      Dim ShareString As String
      ShareString = ShareIntent.GetExtra("android.intent.extra.STREAM")
      ToastMessageShow("Share : " & ShareString, False)
   Else
      ToastMessageShow("No Share action!", False)
      Activity.Finish
   End If

End Sub

 

[Erel]

Which line returns Null?

 

[arr0ba]

ShareString = ShareIntent.GetExtra("android.intent.extra.STREAM")
ToastMessageShow("Share : " & ShareString, False)

 

[Erel]

You can use Intent.HasExtra to check if the extra field exists. In this case it seems that the field doesn't exist.

 

[arr0ba]

I did that and Intent.HasExtra returns True, I also tried to Intent.ExtrasToString this returns a bundle with the value aswell. The problem that I'm having is getting Intent.GetExtra("android.intent.extra.STREAM" ) to return the value of the URI, Instead it always returns null I believe this might be a bug. Can I use reflector Library to get the value and if so how do I do this?

 

[Erel]

Check the unfiltered logs and see if there is an error message about a casting error (when you call Intent.GetExtra).

[Erel]

In that case you will need to use reflection:

Dim r As Reflector
r.Target = i 'the intent object
uri = r.RunMethod2("getParcelableExtra", "android.intent.extra.STREAM", "java.lang.String")

Thank you... the following code works...



Sub Activity_Resume

ShareIntent = Activity.GetStartingIntent
ToastMessageShow(ShareIntent.Action,False)
If ShareIntent.Action = "android.intent.action.SEND" Then
If ShareIntent.HasExtra("android.intent.extra.STREAM") = True Then
'Using reflector library since this does not work without it...
Dim r As Reflector
r.Target = ShareIntent 'the intent object

Dim ShareString As String
ShareString = r.RunMethod2("getParcelableExtra", "android.intent.extra.STREAM", "java.lang.String")

ToastMessageShow(GetPathFromContentResult(ShareString),True)
End If
Else
ToastMessageShow("No Share action!", False)
Activity.Finish
End If
End Sub
