Android Question Share bitmap png

[Emme Developer]

Hi to all!
I'm trying to implement this code to share bitmaps, and it works like expected. But i don't know why, external application doesn't pick also the Alpha value (my pngs have a transparent background). I tried to edit the intent type in "image/png", but i Always get black background. Anyone can help me?
Thanks!

you should upload a example sender and a exapmple receiver which shoes the issue.

Hard to help without seeing your code.

Edit to add:

Is this the sender or the receiver?
