A radio app offers you a choice of radio streams you can use to listen to online radio on your smartphone. The radio program is transmitted via the Internet and not via FM or HD Radio. There are apps which only offer one radio station, a group of radio stations, or only radio stations from a certain country.
The built-in FM radio tuner is now considered a basic feature. It allows the user to listen to most of the live-broadcasted FM radio stations. Almost all phones with FM radio tuner require a wired headset to be connected to the unit as it's used as an antenna.
FM is short for frequency modulation, which refers to the means of encoding the audio signal on the carrier frequency. FM full power, low power, translator and booster stations operate in the 88 – 108 MHz band. There are many classes of radio stations.
As far as I know, there is no general API for FM radio on Android, because every supplier uses their owen radio chipset. Worst of all, the last Google phone is shipped with no radio at all, which gives little possibilities that there will ever be a native FM radio API by Android itself.
The only project that manage to get close into supporting all devices is Spirit FM, which unfortunately is available as an App and does not offer an open API, but you may try to have some co-operation if you contact them.
Another future option may be the "Euro-Chip" which is being pushed by the European Broadcasting Union, which will for sure have a standard API. But it will take quite some time until this gets broadly into the market, if it ever manages to.
