1. customCacheKey for DASH/HLS/SS is now asserted against
in DownloadRequest
2. Merging of event delivery in DownloadManager is very
tricky to get right and probably not a good idea

Currently SimpleCache will touch cache spans whenever it reads
from them. With legacy SimpleCache setups this involves a potentially
expensive file rename. With new SimpleCache setups it involves
a more efficient but still non-free database write.
For offline use cases, and more generally any use case where the
eviction policy doesn't use last access timestamps, touching is
not useful. This change allows the evictor to specify whether it
needs cache spans to be touched or not. SimpleCache will only touch
spans if the evictor requires it.
Note: There is a potential change in behavior in cases where a
cache uses an evictor that doesn't need cache spans to be touched,
but then later switches to an evictor that does. The new evictor
may temporarily make sub-optimal eviction decisions as a result.
I think this is a very fair trade-off, since this scenario is
unlikely to occur much, if at all, in practice, and even if it
does occur the result isn't that bad.

One goal we forgot about a little bit was to allow applications
to provide their own index implementation. This requires the
writable side to also be defined by an interface.

ImaAdsLoader gets the player position after the app releases
the player to support resuming ads at their current position
if the same ads loader is reused.

And all public methods from ShadowLegacyLooper get pushed up to ShadowLooper

Copybara: OK
Also adjust Google3 tests using custom looper shadows where necessary.
Convert exoplayer to paused looper to eliminate reliance on custom shadows

The removed condition only applies when prepare fails and no timeline was or
is known. We should keep a pending seek position in such a case. The internal
player does the same thing already.

- Expose constructors that take DatabaseProvider. Deprecate those
that do not.
- Expose Cache.getUid. This will likely be used for naming of the
tables accessed by DefaultDownloadIndex .

- Allows enforcing immutability, which in a future CL will allow
avoiding allocating a new array/list on every call.
- Also some left over doc cleanup from the DownloadState rename.

The old domain automatically forwards to the new one. For consistency, change
all doc and code references regardless.
Also adds GitHub CNAME config file which configures our page for the custom
domain.

handleSourceInfoRefreshed checks for various conditions which may trigger a
change in position. In all cases, we need to resolve the new position for ads,
and if the corresponding MediaPeriods already exist, perform the seek to the new
position.
This change simplified the code by
1. Moving all conditions in a single if-else structure which just determines
the new playback position. This makes it easier to read and to follow.
2. Doing the subsequent seek and position update in one final step to remove
duplicated code.
As a side effect, it also improves some edge cases. For example when skipping
an ad to an already prebuffered period, we now properly update the existing
prebuffered period.

- Make a best effort to avoid posting MSG_DOWNLOAD_THREAD_STOPPED
if the internal thread has already quit. Doing so is harmless,
but causes an error in Logcat. We used to generate this warning
quite a bit in ExoPlayerImplInternal as well, and we got quite
a few issues filed about it, so best to avoid it if possible.
- Null out the back reference DownloadThread holds to its manager
on release. This avoids a potential issue where a download thread
can prevent GC of its manager if it doesn't cancel quickly.
There's similar logic (with a similar comment) in Loader.LoadTask.

- Rename getAllDownloads to getCurrentDownloads to make it clear
that it doesn't include completed and failed downloads
- Change getDownloadCount to isWaitingForRequirements, which is
what it's used for. Added TODO to make it returns the right thing

Non-trivial download state transitions are currently split across
DownloadManager and Download. These transitions are part of the
same state machine, so it's clearer if they're all in the same place
(i.e. DownloadManager, since this is the component that transitions
downloads between states).

The only state DownloadInternal holds is duplicate of state contained
in Download, but can confusingly be temporarily out of sync. This is
error prone because it's easy to use the wrong variable (e.g.
download.state vs state). DownloadInternals methods are called into
and call out into DownloadManager, which makes some code paths that
are quite hard to follow.
It's possible to simplify DownloadManager quite a lot by removing the
duplicated state in DownloadInternal, at which point DownloadInternal's
methods flatten into DownloadManager, which can just hold an internal
list of Downloads directly.
This is a first step, which makes it clear that DownloadThready only
needs its immutable DownloadAction + an isRemove flag.

Put methods into a more sensible order (the same order as
in the switch statement, which is a more natural order with
e.g. initialize coming first and release coming last).
PiperOrigin-RevId: 242891742
- Changed startDownloads/stopDownloads back to their previous behavior
of starting and stopping all downloads at the manager level.
- Made setManualStopReason methods for the new case of setting a manual
stop reason or some or all downloads.
- Added plumbing to specify an initial manual stop reason when adding a
new download, without also overwriting the manual stop reasons of all
other preexisting downloads. Using the value is left as a TODO pending
a bit of further cleanup that'll make it easier.
PiperOrigin-RevId: 242891688
- Remove NETWORK_TYPE_NOT_ROAMING and NETWORK_TYPE_METERED
because JobScheduler doesn't support them, and they're
probably not useful to many people (data when roaming is
normally enabled/disabled at the OS level, and restricting
to *only* metered networks seems niche)
- Convert network requirements proper flags
- Stop persisting requirements in DownloadIndex. The direction
we're headed to solve the manager start/stop problem is
going to involve state in DownloadManager determining whether
downloads actually start, and if we're doing that then it's
no worse to do it for this as well

Robolectric calls messages posted to the main thread immediately inline. This
will change in the upcoming release and will break tests implicitly relying
on that behavior.
Update ConcatenatingMediaSourceTest to actually wait for the posted message.

HashMap.values does not guarantee a stable order, but our tests
assert that the order is stable. It's probably a nice property
that the order is the same as that in which downloads are added,
so this change makes the order stable, with that order.
A future change will likely improve the way this works, by
changing the internal thread "downloads" variable to have type
ArrayList<Download>, at which point the internal thread can just
pass a read-only copy of its list to the main thread whenever a
state changes.
