This is very stange... I experienced the same problems that you for
some days, and now after comlaining and submitting a bug, it suddently
works without any changes to my code. In my case, I setup a
IntentFilter for some Mime Types, and opened an attached VCF-File in
the Email App with the "Open" Button. It starts my activity in this
way:
Starting activity: Intent { action=android.intent.action.VIEW
data=content://com.android.email.attachmentprovider/f70bd905-0a85-4355-
a56f-a41ef6e20100.db/222/RAW flags=0x1 comp={com.companyname/
com.companyname.ActivityName} }
So everything is fine with the "Email" app. Even the Mime type is
somehow getting through (that is, I think so, because how else would
Android know to delegate this Intent to my app?)
But I still experience the same problems with the Gmail App. It
supplies a "Preview" button and a click starts a download but yields
"The attachment could not ne fetched because this type of file cannot
be displayed on the phone." Maybe I need to adjust my IntentFilter to
handle the file:// protocol, I'll try that and report about it.
