I implemented a Loader in my application for querying data from the database. I listen the changes that happen' by implementing LoaderCallbacks<Cursor> listener. The problem that I have is when using the onLoaderReset(Loader<Cursor> loader) method when my data change and I want to invalidate and free any data associated with the loader. In all the examples, in this method there is the following call: mAdapter.swapCursor(null); But the thing is I don't use the data from the cursor in adapter, I use it in some other way in my application. (directly from the returned cursor in onLoadFinished

I'm trying to use an AsyncTaskLoader to load data in the background to populate a detail view in response to a list item being chosen. I've gotten it mostly working but I'm still having one issue. If I choose a second item in the list and then rotate the device before the load for the first selected item has completed , then the onLoadFinished() call is reporting to the activity being stopped rather than the new activity.

Is it possible that loaders are currently broken in the SDK or is there some

I'm creating a chat application and I need a little bit of guidance. I am using a sqlite database to store the chat as it comes in. I want my Activity, when it's open, to load the chat history from that particular chat and to continue to refresh as new chat is entered (my main question is how do I go about doing this). Should I use a CursorAdapter with an inital cursor of a query containing the chat for that conversation and set it as the adapter for the ListView? I have tried this, but the data doesn't refresh when I insert into the database. I know I didn't provide any code, but general
