I like audiobooks a lot and prefer to listen to them instead of listening to music. While there is nothing wrong with music, (mostly) non-fictional audiobooks not only entertain me but also educate me at the same time.
I used to play audiobooks with the built-in Android music player and while that works just fine, it is lacking in several regards.
There is for instance no option to remember the play position of multiple audiobooks which often resulted in me having to use the position slider to find the position I stopped listening the last time.
Listen Audiobook Player for Android is not free -- it costs €0.99 -- but it is reasonably priced in my opinion. Plus, the app itself as a consequence does not feature ads or any form of in-app purchases for monetization.
When you first start the application it asks you to pick a root audiobook folder on your device. It is recommended that each audiobook is in its own directory in that root folder, and if you want, you can exclude the books from being picked up by other media players on the system.
All audiobooks are then displayed in the main interface afterwards. For each, the total playtime, current position and percentage are displayed.
Covers get picked up automatically if stored in the same folder. The first time you tap on an audiobook without cover, you get the option to download it from the Internet.
This displays image search results that you can select an appropriate cover from with a tap.
The controls are basic but that is not necessarily a bad thing. The current position, play time and remaining play time is displayed at the top. You can long press here to jump to another position. The controls at the bottom allow you to go back and forward, while a tap anywhere else on the screen toggles play and pause.
Chapter navigation needs to be enabled in the settings before it becomes available. If you enable it, you find chapters listed under the forward and backward buttons then.
The options menu displays features related to the current audiobook. Here you can enable sleep mode which stops playback after a set period of time, change playback speed or playback volume.
The sleep settings alone fill more than a screen and include interesting options such as resetting the timer by shaking the device, enabling auto-sleep or setting the sleep time itself.
Especially the speed option can come in handy as you can speed up playback slightly to decrease the time it takes to listen to the audiobook.
The author of Listen Audiobook Player has built several other features into the application that improve playback. You can save bookmarks for example or access a position history which get synced across your devices. For that, it is necessary to link a Dropbox account as it is used by the app for the synchronization.
Automatic behaviors are available as well. The app will rewind automatically if the book has been on pause for a specific amount of time, or start to play automatically when it recognizes a bluetooth headset connection. It will furthermore pause if the headset is disconnected and displays options to configure auto resume (or not) after phone calls.
Listen Audiobook Player is a great audiobook player for Android that ships with a rich set of features that leaves little to be desired.
In fact, there is only one feature that I can think of that it does not offer yet, and that is the ability to set multiple root folders for audiobooks.
