I was recently looking for a good Material Design Podcast app. I found Podcast 02, which seemed to be okay, but I found some things that didn't work quite how I wanted them to.
Then I found uPod, and I've got say, I'm hooked. It has a unique inbox style for new Podcasts that I have really been enjoying.
Some features aren't quite as rich as BeyondPod or PocketCasts, but the developer is very responsive and active, working hard on adding new features. On the Google+ page it states that he was considering going Open Source with the app, due to time constraints, but then decided not to due to lack of support. I think that is a shame for such a great app. It is free to use, and has a 7 day trial with all premium features. If you want an awesome Material Design podcast manager, I highly suggest you check it out and give it the support it deserves.
Scala has a higher memory footprint than Java (e.g. Option wrapper around null-APIs). But what you get in return for that is a way more concise language, ridiculously simplified concurrency and a gateway to the beautiful world of functional programming. But all in all, from my experience about standard business application logic you will not notice a performance difference to Java. If you're scared of performance issues, keep in mind that you can mix Scala & Java files.
Concerning the compilation times, yes they are slower. Yes, they are a pain. It depends a lot on your programming style, though. If you move more and more logic into the type level, you increase the workload for the compiler. But you get a more generic and type-checked app, which is nice. Then again, you have sbt, Scala Build Tool, which supports incremental compile. Meaning, once you compiled the code, changing a file will only recompile the affected files, which basically happens in no time.
There are plenty up- and downsides. Frustration about Java in general (not only for Android) was the reason for me to give Scala a chance. Since then I never looked back and shortly after began to introduce it to my Android apps.
This is a rather nice Scala on Android app I am aware of: https://play.google.com/store/apps/details?id=mobi.upod.app
I am currently working on this one, but unfortunately not open to public: https://play.google.com/store/apps/details?id=com.liefery.courier_android_app
