At least for older versions, if multiple selection is allowed (Intent#EXTRA_ALLOW_MULTIPLE), URIs will be returned as clipboard data:
data.getClipData()
See Intent#getClipData() and ClipData.
Check if data is being returned there:
ClipData clipData = data.getClipData();
Uri selectedImage = null;
if (clipData != null) {
selectedImage = clipData.getItemAt(0).getUri();
} else {
selectedImage = data.getData();
}
