New features are:
- New user interface – As I mentioned when we introduced the m3 version of the Android SDK, we’re continuing to refine the UI that’s available for Android. m5-rc14 replaces the previous placeholder with a new UI, but as before, work on it is still in-progress.
- Layout animations – Developers can now create layout animations for their applications using the capabilities introduced in the android.view.animation package. Check out the LayoutAnimation*.java files in the APIDemos sample code for examples of how this works.
- Geo-coding – android.location.Geocoder enables developers to forward and reverse geo-code (i.e. translate an address into a coordinate and vice-versa), and also search for businesses.
- New media codecs – The MediaPlayer class has added support for the OGG Vorbis, MIDI, XMF, iMelody, RTTL/RTX, and OTA audio file formats.
- Updated Eclipse plug-in – A new version of ADT is available and provides improvements to the Android developer experience. In particular, check out the new Android Manifest editor.
