Doogee S55 64Gb+4Gb Dual LTE [23/118] Android extensions

[C-0-1] Device implementations MUST provide complete implementations, including all

documented behaviors, of any documented API exposed by the Android SDK or any API

decorated with the “@SystemApi” marker in the upstream Android source code.

[C-0-2] Device implementations MUST support/preserve all classes, methods, and

associated elements marked by the TestApi annotation (@TestApi).

[C-0-3] Device implementations MUST NOT omit any managed APIs, alter API interfaces

or signatures, deviate from the documented behavior, or include no-ops, except where

specifically allowed by this Compatibility Definition.

[C-0-4] Device implementations MUST still keep the APIs present and behave in a

reasonable way, even when some hardware features for which Android includes APIs are

omitted. See section 7 for specific requirements for this scenario.

3.1.1. Android Extensions

Android includes the support of extending the managed APIs while keeping the same API level

version.

[C-0-1] Android device implementations MUST preload the AOSP implementation of both

the shared library ExtShared and services ExtServices with versions higher than or equal to

the minimum versions allowed per each API level. For example, Android 7.0 device

implementations, running API level 24 MUST include at least version 1.

3.2. Soft API Compatibility

In addition to the managed APIs from section 3.1 , Android also includes a significant runtime-only

“soft” API, in the form of such things as intents, permissions, and similar aspects of Android

applications that cannot be enforced at application compile time.

3.2.1. Permissions

[C-0-1] Device implementers MUST support and enforce all permission constants as

documented by the Permission reference page . Note that section 9 lists additional

requirements related to the Android security model.

3.2.2. Build Parameters

The Android APIs include a number of constants on the android.os.Build class that are intended to

describe the current device.

[C-0-1] To provide consistent, meaningful values across device implementations, the table

below includes additional restrictions on the formats of these values to which device

implementations MUST conform.

Parameter Details

VERSION.RELEASE

The version of the currently-executing Android system, in human-

readable format. This field MUST have one of the string values defined

in 8.0 .

VERSION.SDK

The version of the currently-executing Android system, in a format

accessible to third-party application code. For Android 8.0, this field

MUST have the integer value 8.0_INT.
