## Announcement

### Podcini.R, or Podcini 6, is currently under pre-release for early evaluations.  The major overhaul is the replacement of SQLite DB with the object-based Realm DB. With a different application Id, it can be installed in parallel with a previous version. See [Podcini 6 migrations instroctions](migrationTo6.md)

This project is based on a fork of [AntennaPod](<https://github.com/AntennaPod/AntennaPod>) as of Feb 5 2024.

Compared to AntennaPod this project:

1. Migrated all media routines to `androidx.media3`, with `AudioOffloadMode` enabled, nicer to device battery,
2. Is purely `Kotlin` based and mono-modular, and targets Android 14,
3. Iron-age celebrity SQLite is replaced with modern object-base Realm DB
4. Removed the need for support libraries and jetifier
5. Outfits with Viewbinding, Coil replacing Glide, coroutines replacing RxJava and threads, and SharedFlow replacing EventBus,
6. Boasts new UI's including streamlined drawer, subscriptions view and player controller,
7. Accepts podcast as well as plain RSS and YouTube feeds,
8. Offers Readability and Text-to-Speech for RSS contents,
9. Features `instant sync` across devices without a server.

The project aims to profit from modern frameworks, improve efficiency and provide more useful and user-friendly features.

While podcast subscriptions' OPML files (from AntennaPod or any other sources) can be easily imported, Podcini can not import DB from AntennaPod.

## Notable new features & enhancements

### Player

* More convenient player control displayed on all pages
* Revamped and more efficient expanded player view showing episode description on the front
* External player class is merged into the player
* Playback speed setting has been straightened up, three speed can be set separately or combined: current audio, podcast, and global

* The "Skip to next episode" button on the player
  * long-press moves to the next episode
  * by default, single tap does nothing
  * if the user customize "Fast Forward Speed" to a value greater than 0.1, it behaves in the following way:
    * single tap during play, the set speed is used to play the current audio
    * single tap again, the original play speed resumes
    * single tap not during play has no effect
* Added preference "Fallback Speed" under "Playback" in settings with default value of 0.0, dialog allows setting a float number (capped between 0.0 and 1.5)
* if the user customizes "Fallback speed" to a value greater than 0.1, long-press the Play button during play enters the fallback mode and plays at the set fallback speed, single tap exits the fallback mode
* Various efficiency improvements, including removal of:
  * redundant media loadings and ui updates
  * frequent list search during audio play
* streamed media somewhat equivalent to downloaded media
  * enabled episode description on player detailed view

### Podcast/Episode list

* A whole new interface of the Subscriptions page showing only the feeds with tags as filters, no longer having tags as folders in the page,

* Long-press filter button in FeedEpisode view enables/disables filters without changing filter settings
* Subscriptions view has various explicit measures for sorting
* in Subscriptions view, click on cover image of a feed opens the FeedInfo view (not FeedEpisodes view)

* externally shared feed opens in the new online feed view fragment
* OnlineFeedView` activity is stripped down to only receive externally shared feeds
* Youtube channels are accepted from external share or paste of address in podcast search view, and can be subscribed as a normal podcast, though video play is handled externally

### Instant (or Wifi) sync

* Ability to sync between devices on the same wifi network without a server (experimental feature)
* It syncs the play states (position and played) of episodes that exist in both devices (ensure to refresh first) and that have been played (completed or not)
* So far, every sync is a full sync, no sync for subscriptions and media files

### Security and reliability
