Google released on Wednesday a new version of the software development kit for its open mobile platform called Android.

The new SDK has a new user interface, a geocoder that lets developers search for businesses as well as translate an address into a coordinate and vice versa, support for new media codecs, and code that lets developers create layout animations.

One thing missing is change to the telephony package, laments one developer on the Android Developer discussion on Google Groups.

“This is very disappointing, especially because we were told in the Android coding day in Israel that the telephony package will be updated soon,” the developer wrote. “We still cannot detect the ingoing/outgoing call number or send DTMF tones properly.” Prototypes of Android phones were shown at the GSMA Mobile World Congress in Barcelona on Monday. Google launched Android in November along with and the Open Handset Alliance, a consortium of 34 handset manufacturers, carriers and chipmakers that have said they plan to support Android products and services. Products are due out later this year.
