As you probably know, Google last week launched the latest version of its Android operating system, known as the Jelly Bean (v. 4.1). This is the latest version to be built over Ice Cream Sandwich, which was officially presented to the public early in the event Google I / O. Basically, Android 4.1 Jelly Bean offers a user interface faster and more fluid experience to voice search, which some say could almost pass for an Apple Siri bygone technology, research and capacity are improved.
The SDK is already available since last week as a developer preview developer.android.com from the site. Android 4.1 Jelly Bean will arrive in mid-July on some devices.
The Android platform Software Development Kit (PDK) is designed for developers and hardware partners will be available for Android devices in 2 to 3 months before the release date of future versions of Android. A beta version of PDK Jelly Bean has already been made available to everyone on an ongoing basis.
