Our Android background services should listen for system intents that warn about battery, network, or device storage conditions. When we receive any of the following warning intents, we should probably stop our background services: ACTION_BACKGROUND_DATA_SETTING_CHANGED (if disabled) ACTION_BATTERY_LOW ACTION_DEVICE_STORAGE_LOW CONNECTIVITY_ACTION (if disconnecting) When we receive any of the following intents, we should check whether battery, network, and device storage are "happy" before restarting our background services: ACTION_BACKGROUND_DATA_SETTING_CHANGED (if enabled) ACTION_BATTERY_OKAY ACTION_DEVICE_STORAGE_OK ACTION_POWER_CONNECTED CONNECTIVITY_ACTION (if reconnecting) Also, if we want to perform alert actions when we know the user is (probably) looking at their phone, we can listen ACTION_SCREEN_ON and ACTION_USER_PRESENT. If we want to perform actions when we know the phone is idling, we could listen for ACTION_SCREEN_OFF and ACTION_DREAMING_STARTED.
