Google has also addressed another frequently-cited concern of Android developers, namely people copying their apps without paying.
"From Jelly Bean and forward, paid apps in Google Play are encrypted with a device-specific key before they are delivered and stored on the device," the company wrote in a developer blog post. "We know you work hard building your apps. We work hard to protect your investment."
Jelly Bean also comes with new APIs for accessibility services, making it easier for developers to integrate gesture-based commands for the visually-impaired. Other new APIs target functionality such as network bandwidth management and low-level media codec access.
In a move that could prove useful to both users and developers, Google has updated the Play store so that app updates no longer require the fresh downloading of the app's entire installation package (APK). Instead, the new 'smart app update' will only download the part of the APK that has changed, saving on bandwidth and battery.
According to Google, there are now more than a million new Android device activations each day. :sign0060:
