Transistor Radio

Transistor is a bare bones app for listening to radio programs over the internet. The app stores stations as files on your device's external storage. It currently understands streams encoded in MP3, AAC and Ogg/Opus(*).

Important note: This is an app of type BYOS ("bring your own station"). It does not feature any kind of built-in search option. You will have to manually add radio stations.

Transistor is free software. It is published under the MIT open source license. You can find the code on GitHub (https://github.com/y20k/transistor). GitHub is also a good place to file bugs or even to contribute, if you are interested.

The rename and delete options can be accessed both from the station's detail screen. Just tap on the three dots symbol. You can manage the list of stations also from a file browser (see next question).

+ Where does Transistor store its stations?

Transistor does not save its list of stations in a database. Instead it stores stations as m3u files on your device's external storage. Feel free to tinker with those files using the texteditor of your choice. The files are stored in /Android/data/org.y20k.transistor/files/Collection.

+ How do I backup and transfer my radio stations?

Transistor supports Android 6's Auto Backup feature. Radio stations are always backed up to your Google account and will be restored at reinstall. On devices running on older versions of Android you must manually save and restore the "Collection" folder.

+ Why does Transistor not have any setting?

There is nothing to be set ;). Transistor is a very simple app. Depending on your point of view "simple" is either great or lame.

This permission is needed to install and uninstall radio station shortcuts on the Android Home screen.
