This is due to a bug in AsyncTask in the Android framework. AsyncTask.java has the following code:
private static final InternalHandler sHandler = new InternalHandler();
It expects this to be initialized on the main thread, but that is not guaranteed since it will be initialized on whichever thread happens to cause the class to run its static initializers. I reproduced this issue where the Handler references a worker thread.
・The AsyncTask class must be loaded on the UI thread. This is done automatically as of JELLY_BEAN.
・execute(Params...) must be invoked on the UI thread.
Thus, there are simply two rules to Android's single thread model:
1. Do not block the UI thread
2. Do not access the Android UI toolkit from outside the UI thread
If you have operations to perform that are not instantaneous, you should make sure to do them in separate threads ("background" or "worker" threads).
AsyncTask enables proper and easy use of the UI thread. This class allows to perform background operations and publish results on the UI thread without having to manipulate threads and/or handlers.
An asynchronous task is defined by a computation that runs on a background thread and whose result is published on the UI thread.

managedQuery() will use ContentResolver's query(). The difference is that with managedQuery() the activity will keep a reference to your Cursor and close it whenever needed (in onDestroy() for instance.) If you do query() yourself, you will have to manage the Cursor as a sensitive resource. If you forget, for instance, to close() it in onDestroy(), you will leak underlying resources (logcat will warn you about it.)
