Some Android devices lack a full framework layer, limiting their features.
Tradefed supports these devices, termed NativeDevice.
Architecture
Our device representation uses a layered architecture. TestDevice extends
NativeDevice, reflecting that native devices are a subset of full Android
devices.
The implementation automatically handles the various situation of device state detection and device availability.
Enable support
If the NativeDevice is started by Tradefed like in the case of virtual devices,
use the following option:
base-device-type-request = 'NATIVE_DEVICE'
if the device is pre-existing, set the NOTIFY_AS_NATIVE
environment variable when starting Tradefed. Specify NOTIFY_AS_NATIVE as a
comma separated list of the serials of device to be considered non-full
framework.
NOTIFY_AS_NATIVE=<serial>,<serial1> ./tradefed.sh
