BaseTV
(adb, host, port=5555, adbkey='', adb_server_ip='', adb_server_port=5037, state_detection_rules=None)[source]¶ 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 = ('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 themedia_session_state()
property to determine the state'audio_state'
= try to use theaudio_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 stateThe valid properties are
'media_session_state'
,'audio_state'
, and'wake_lock_size'
