Objects Still In Localstore After Unpinallinbackground(list<...>, Deletecallback)

I'm using Parse.com in my Android app. I'm making a collaborative shopping list which allows the user to mark items for deletion (they turn grey), but they only get actually delete

Solution 1:

Ok, so I solved it. From what I understood, what I was trying to do is not possible using the parse library.

First of all, deleteAllInBackground() also unpins objects, so the unpinAllInBackground() is not needed.

The problem is that I was pinning the objects using item.pin(MyApplication.ALL_ITEMS), thus the only way to unpin them is by passing the pin name using item.unpinInBackground(MyApplication.ALL_ITEMS). However, the batch version does not allow to pass as argument both a collection of items AND the pin name. Thus, it isn't possible to batch unpin items with a named pin.

I ended up unpinning the objects individually passing the pin name. The big complain I have is that doing item.unpinInBackground() without the pin name does not throw an exception and thus I was not aware what the problem was.
