aio_androidtv.basetv module

Communicate with an Android TV or Amazon Fire TV device via ADB over a network.

ADB Debugging must be enabled.

class aio_androidtv.basetv.BaseTV(host, port=5555, adbkey='', state_detection_rules=None)

Bases: object

Base class for representing an Android TV / Fire TV device.

The state_detection_rules parameter is of the format:

state_detection_rules = {'com.amazon.tv.launcher': ['idle'],
                         'com.netflix.ninja': ['media_session_state'],
                         'com.ellation.vrv': ['audio_state'],
                         'com.hulu.plus': [{'playing': {'wake_lock_size' : 4}},
                                           {'paused': {'wake_lock_size': 2}}],
                         'com.plexapp.android': [{'paused': {'media_session_state': 3, 'wake_lock_size': 1}},
                                                 {'playing': {'media_session_state': 3}},
                                                 'idle']}

The keys are app IDs, and the values are lists of rules that are evaluated in order.

VALID_STATES

VALID_STATES = ('idle', 'off', 'playing', 'paused', 'standby')

Valid rules:

• 'idle', 'playing', 'paused', 'standby', or 'off' = always report the specified state when this app is open

• 'media_session_state' = try to use the media_session_state() property to determine the state

• 'audio_state' = try to use the audio_state() property to determine the state

• {'<VALID_STATE>': {'<PROPERTY1>': VALUE1, '<PROPERTY2>': VALUE2, ...}} = check if each of the properties is equal to the specified value, and if so return the state

  • The valid properties are 'media_session_state', 'audio_state', and 'wake_lock_size'

Parameters

• host (str) – The address of the device; may be an IP address or a host name

• port (int) – The device port to which we are connecting (default is 5555)

• adbkey (str) – The path to the adbkey file for ADB authentication

• state_detection_rules (dict, None) – A dictionary of rules for determining the state (see above)

aio_androidtv.basetv.state_detection_rules_validator(rules, exc=<class 'KeyError'>)

Validate the rules (i.e., the state_detection_rules value) for a given app ID (i.e., a key in state_detection_rules).

For each rule in rules, this function checks that:

• rule is a string or a dictionary

• If rule is a string:

  • Check that rule is in VALID_STATES or VALID_STATE_PROPERTIES

• If rule is a dictionary:

  • Check that each key is in VALID_STATES

  • Check that each value is a dictionary

    • Check that each key is in VALID_PROPERTIES

    • Check that each value is of the right type, according to VALID_PROPERTIES_TYPES

See BaseTV for more info about the state_detection_rules parameter.

Parameters

• rules (list) – A list of the rules that will be used to determine the state

• exc (Exception) – The exception that will be raised if a rule is invalid

Returns

rules – The provided list of rules

Return type

list
