The Analog Adapter Accessory Mode as described in the USB Type-C
specification appendix A multiplex analog audio signals onto the

when the support is not universal across different Android devices

Screen zoom enables users to reconfigure the display size, thereby
improving device accessibility for users with low vision.

The modification of the display density might impact apps if not
implemented carefully and thus the requirement also spells out
the boundary conditions when implementing the feature.

CDD: High perf VR devices requires BT 4.2 and LE Data Length

High performance VR device implementations are expected to be
used in a full-immersive nature, which means there would be a
need to have controllers typically external to the device.
Bluetooth 4.2 and LE Data Length extensions would be the baseline
foundation to grow an interoperable ecosystem of such accessories
upon which apps can rely on.

CDD: Update app private storage requirements.

Bumping the generic requirement up from 1.5GB to 3GB since:

a. the size of apps being distributed are growing
b. the statistics on median usage of the data/ partition is now over
2GB across devices from various geographies
c. the change was already hinted since 2 years ago

Reducing television requirements from 5GB to 4GB, because the
adoptable storage feature introduced in Android 6.0 are widely
adopted by televisions and can be used to meet the need for larger
app private storage

CDD: Require detection of three key ranges, strongly recommend fourth key range.

In order to support a more consistent behavior of the keys commonly used
on 3.5mm headsets across Android devices, Android 5.0 introduced a
recommended impedance range to detect the following four headset keys;

- KEYCODE_HEADSETHOOK ~ 70Ω
- KEYCODE_VOLUME_UP 210 ~ 290Ω
- KEYCODE_VOLUME_DOWN 360 ~ 680
- KEYCODE_VOICE_ASSIST 110 ~ 180Ω

In Android 7.0, we now REQUIRE that Android devices with a 3.5mm
four-conductor audio jack would at least map the the ranges defined for
the first three keys onto the same keycode events.

Some devices upgrading to Android 7.0 might not necessarily have the
hardware with sufficient resolution range to properly detect four ranges,
especially to distinguish between the two lower impedance ranges. Hence,
we do NOT REQUIRE the detection of the KEYCODE_VOICE_ASSIST yet.

CDD: Clarify external cameras MAY be connected through non-USB ports.

Previously the CDD requirements for external camera assumed the device
is connected with the external camera through the USB port.

As this does not have to be necessarily the case, the requirements are
rewritten to allow device implementations to introduce new mechanisms
to connect the external camera(s) with the device.

Android 7.0 adds support to control the camera through the native

We also make it a requirement to have memory of at least 3 times the
maximum camera resolution, which was previously recommendation only.
