ContentProviders are allowed to return null and both
of our contact directories (Focus and Exchange) actually
do when they find no data to return.
The problem is that when LoaderManager receives a result
from a loader, it checks if the result is the same as
previously received. That's fine, as long as the loader
always returns a different result. Now consider a loader
that returns null when it cannot produce the result.
What we are seeing is that if the loader is rapidly restared
and returns null twice in a row, the null is never
delivered to the callbacks.
In the case of the reported bug, the scenario is this:
1. We look for "foo"
2. Data for "foo" comes from a directory and we display it
3. We hit backspace twice in rapid succession. Each time
we hit backspace, the loader is restared, but since we do
this very fast, the second restart overrides the first. So
far so good.
4. The directories are programmed to return null if the
query string is less than 3 characters long, so the loader
returns null twice.
5. Loader manager looks at the final result, compares it
to the previous result and since they are the same (both null)
concludes that it does not need to deliver either of them.
6. The UI attempts to show the stale data and blows up

Also hide the bitmap thumbnail stuff, we can't support it in its
current form.
And fix some bugs with propagating paths to native code. Yikes!

When measuring a package's usage, put the external size in the
PackageStats as well. This will allow programs using a lot of space on
the external card to be held accountable.

The default is now to serialize everything onto the thread pool. If you would
like to have finer grained control over how AsyncTasks are executed, you can
call the new executeOnExecutor method, which takes a custom Executor. The
pool used by the default is handily now accessible as THREAD_POOL_EXECUTOR.
This change is because it is too tempting to convert single threaded Janky™
code to use AsyncTask in a way that is unsafe and ends up calling the
AsyncTasks in parallel.
Also, this adds a static execute(Runnable) method to AsyncTask that posts
onto the serialized queue, so that if you don't have any parameters or
return values, you can just use Runnable instead of AsyncTask.

You can now do android:largeHeap="true" on an application.
Doesn't yet do anything, waiting for Dalvik API.
Also tweak package parsing so that the SDK API level is set in the
configuration, allowing manifest resource value selection based on
that.

Added check avoid a division by zero resulting in NaN which in turn
makes checkFullyTilted to ignore high tilt angles from then on.
If (x, y, z) == (0, 0, 0) then there is no tilt or rotation and
this vector must be ignored. This check is extended to ignore all
small acceleration values where noise can be of big influence.
Low or zero readings can happen when space travelling free falling,
but more commonly when shaking or getting bad readings from the sensor.
The accelerometer is turned off when not used and polling it too soon
after it is turned on may result in (0, 0, 0).

docs: Rewrite of App Fundamentals.. Part 2.
This introduces three new docs:
Services:
Provides an introduction to using services and describes the
service lifecycle (previously in the "Component Lifecycles" section
of the fundamentals.jd document)
Bound Services:
A guide for services that offer binding.
AIDL:
A doc about using AIDL (primarily for creating a service interface)
Also includes edits to IntentService javadocs to clarify
different behaviors for some callback methods
Includes a new version of the services lifecycle diagram
and an additional diagram for determining onRebind()
These files are orphaned for now---they're not linked in the sidenav,
until I get the last couple documents submitted for the app fundamentals.

There was a lot of fancy code just above the clear to ensure
that drawables that aren't affected by the change are kept,
then the entire array was cleared. This patch removes the
clear, so that the drawables that haven't changed are really
kept, matching the logs, comments and larger part of the code.
This patch also fixes the various constant states to return
correct ChangingConfigurations.
