I’ve just been using the audio player on ES File Explorer. It tends to forget all its state and has various other UI problems.
I’m interested in an audio player that will keep playlists for me, and remembers its state so I can resume playback. My main use case is to cue up podcasts for driving, so I want it to save my place when I don’t finish listening to a whole episode during my drive. Saving my place in multiple playlists would be great too, like an audiobook and a series of podcast episodes would both have saved state so I could switch between them.
Ideally it would also activate playback whenever the phone connects to a particular bluetooth device - my car audio. The use case is I hop in the car, turn on my bluetooth receiver, and audio resumes without me needing to take the phone out of my pocket. Turn off bluetooth, playback stops.
I use vlc. But it does not create playlists that can be exported and then imported again, so I am making my own .m3u file
Why not use a podcast manager like antennapod?
Sounds like it has all the things you are looking for.
[Edit: This is comment more suited for music, not podcasts.]
I’ve tried a lot and I think VLC is probably the best I have found so far. It has the resume playback option:
(I also have innertune and newpipe to listen to songs online from youtube and… spotify for some rare occasions.)
It seems that you want a Podcast player and an Audiobook player. I use two different apps for that : AntennaPod for podcasts and Voice for Audiobooks. You can use AntennaPod also for Audiobooks, but I like to separate the two.
I’m not sure if it’s helpful , but Vinyl and Vanilla are good mp3 players. Both are available on Fdroid
