[android-developers] Re: setAccuracy vs setHorizontalAccuracy

Hi,

Not I, but you could guess that these relate in a device, cost &/or technology independant manner about what (Location) accuracy is desired by your app.

The current technologies that the OS might choose from based on your settings include GPS (fine or high accuracy), Wifi access point (medium accuracy), Cell Tower (low accuracy) & Barometer (for medium vertical acurracy ?), public IP address (low accuracy?)  where those technologies are supported by the end users device.

By presenting the Location accuracy options in a technology independant manner Android also leaves open the possibility of supporting other Location based techniques in future, such as Bluetooth, RFID, NFC, and other passive wireless techiques, using sensors etc. And to do this with you needing to update your app.

Great - my question as stated in the OP is _why have 2 methods with different set of integer parameters (why not an enum btw) doing the exact same thing_ not why I do not ask for GPS or wifi by name.
Please read more carefully before posting

As internally accuracy just sets `mHorizontalAccuracy` I wonder why both setHorizontalAccuracy() and setAccuracy() - and no less than 6 constants - are provided.

Anyone knows ?

setAccuracy

setHorizontalAccuracy

Another example of the pristine android docs. So what is the difference ? Notice they take different constants - is it possible/desirable to specify both with some combination of constants ?
