Podcast Addict is developed by Xavier Guillemane and can be downloaded on Google Play Store: https://play.google.com/store/apps/details?id=com.bambuna.podcastaddict&hl=en_US&gl=US

Podcast Addict can be controlled through the sending of remote commands called 'Intents'.
Some 3rd parties apps specialized in task automation will then allow you to control Podcast Addict. For example, you will be able to wake up to the sound of your playlist or to start automatically playing when some NFC tag has been detected.
In Tasker, you just need to copy/paste one of the following intent in the task Action field ("Misc" action type then select "Send Itent") .
If you prefer Automate It, you can use the Podcast Addict plugin that will save you some configuration time (https://play.google.com/store/apps/details?id=com.smarterapps.podcastaddictplugin )
Before using an intent make sure to set the following:
Package: com.bambuna.podcastaddict
Class (UPDATE intent only): com.bambuna.podcastaddict.receiver.PodcastAddictBroadcastReceiver
Class (every other intent): com.bambuna.podcastaddict.receiver.PodcastAddictPlayerReceiver

You can pass an optional boolean argument called "arg2" in order to select if the app UI should be opened. Without this parameter the playlist will be displayed
