Can you use a LoaderManager from a Service?

Does anyone know why LoaderManager was excluded from Service?

As stated in the other answer, LoaderManager was explicitly designed to manage Loaders through the lifecycles of Acivities and Fragments. Since Services do not have these configuration changes to deal with, using a LoaderManager isn't necessary.

If not is there a way around this?

Yes, the trick is you don't need to use a LoaderManager, you can just work with your Loader directly, which will handle asynchronously loading your data and monitoring any underlying data changes for you, which is much better than querying your data manually.

First, create, register, and start loading your Loader when your Service is created.

@Overridepublic void onCreate() {    mCursorLoader = new CursorLoader(context, contentUri, projection, selection, selectionArgs, orderBy);    mCursorLoader.registerListener(LOADER_ID_NETWORK, this);    mCursorLoader.startLoading();}

Next, implement OnLoadCompleteListener<Cursor> in your Service to handle load callbacks.

@Overridepublic void onLoadComplete(Loader<Cursor> loader, Cursor data) {    // Bind data to UI, etc}

Lastly, don't forget clean up your Loader when the Service is destroyed.

@Overridepublic void onDestroy() {    // Stop the cursor loader    if (mCursorLoader != null) {        mCursorLoader.unregisterListener(this);        mCursorLoader.cancelLoad();        mCursorLoader.stopLoading();    }}

Unfortunately, no. Loaders were designed for activities and fragments in order to cleanly handle configuration changes that occur in Activites and Fragments. i.e. Rotating your device and re-attaching to the existing data.

A service does not have any configuration changes, it will sit in the background until it completes or the system is forced to kill it. So assuming you're executing your code on a background thread in your Service (which you should be anyways), theres just no reason to use a Loader. Simply make the calls you need to query your data.

So if your Service is just an IntentService, you can write your logic to query your cursor-backed data in the onHandleIntent() method.
