passed to TrackSelection.updateSelectedTrack was incorrectly set to
0. It should have been set to correctly reflect buffered media in
previous periods still being played out.
- This change fixes the issue described above, and also propagates the

This change fixes various issues:
- MobileHarness sometimes allocated devices with SDK < 16. As we have no tests running
on these SDKs, a new dimension filter for the mobile_test target ensures that only
devices with SDK >= 16 are selected. A similar filter for SDK version is also added
to the ABR playback tests to ensure no old devices are selected.
- DRM specific tests are skipped for Api < 18, but were not able to run because the
DashTestRunner class tried to link to the MediaDrm constructor. Moved the
constructor to a seperate Builder class to allow execution on Api levels 16 and 17.
- DashWidevineOfflineTest also tried to access code for Api >= 18 without checking
the current level.
- Action implementations which are waiting for events did not ensure that they have a
nextAction to wait for. This caused NullPointerExceptions when this next action was
scheduled.
- DefaultDrmSession always restored the offline keys when a new license was requested,
even if the keys were already restored. These repeated slow calls to restoreKeys
resulted in high numbers of dropped buffers.

- Otherwise, use one of the following values as tie-breaker in order:

- SampleRate
- BitRate

Controls are still hidden while playing ads, but if the app pauses the player,

When the player enters the background then returns to the foreground, the

Updates DefaultDrmSessionManager to use the prefered Widevine version (v1

For other DRM schemes, uses the first scheme found.
* Always assume a renderer is ready if it's read to the end of
its current stream and there's a subsequent period already
prepared. This prevents getting stuck when a non-clock renderer
has a short stream.
* Switch to the standalone clock if the renderer providing the
media clock has read to the end of its current stream, is no
longer ready, and there's a subsequent period already prepared.
This prevents getting stuck when a clock renderer has a short
stream.
* Remove unnecessary clock synchronization logic (since it would
need to be made more complicated as a result of this change).
* Don't update the playing period holder when playWhenReady is
false. This avoids the position jumping to the start of the
next period when seeking to the very end of the current period
whilst paused (we still end up showing the first frame of video
from the next period, but fixing that will have to wait).

Currently, to make transition to next media period seamless, after the renderer
has read until the end of the current SampleStream, we may send it the next
SampleStream so the renderer may read from the next SampleStream ahead of the
transition.
For NoSampleRenderer, we should avoid doing this: skipping ahead for such
renderer doesn't have any benefit (the renderer does not consume data from
SampleStream), and it will change the provided rendererOffsetUs while the
renderer is still rendering from the playing media period.

There are use-cases, in which the users want to have simple Renderer

Remaining instrumentation tests either use android.os.Handler or rely on assets.
In the latter case, the tests are difficult to migrate due to differences
between the internal and external build systems, and configuration needed in
Android Studio. In addition, SimpleCacheSpanTest remains as an instrumentation
test because it fails due to a problem with string encoding on the internal
build (and two other tests in its package are kept with it because they depend
on it).
This test removes a dependency from testutils on Mockito, as a different
version of Mockito needs to be used for instrumentation tests vs Robolectric
tests, yet both sets of tests need to rely on testutils. Mockito setup is now
done directly in the tests that need it.
Move OggTestData to testutils so it can be used from both instrumentation and

We do this in the dynamic case, and I think we've seen
a few GitHub issues where developers do this and don't
understand what they've done wrong (because the failure
comes later).

Currently the ExoPlayerWrapper is used to run tests using an ExoPlayer
implementation. Some properties of the test are set in the constructor, some
are set by overloading the class, others are hard-coded in the
ExoPlayerWrapper class, and a mechanism similar to the existing ActionSchedule
is missing.
This change does the following:
1. Renames ExoPlayerWrapper to ExoPlayerTestRunner as it better reflects
its purpose.
2. Adds an internal Builder to easily set-up the test in a coherent way. This
allows to only set necessary test components while using defaults for the rest.
3. Integrate ActionSchedule.
4. Apply the new structure to the existing tests currently using ExoPlayerWrapper.
