At ever Google I/O a new version of Android seems to be released. So with this knowledge, it would seem that Android 5.0 (presumably called Key Lime Pie) would be announced on May 15th when I/O’13 starts. Unfortunately, there seems to be several new rumors making the rounds on the internet that the brand new operating system will not be ready by the time the developer conference starts.
Android Police also started to track new version of Android visiting different websites. This new Android version is codename JWR23B. Unless Google plans to put out a major update to Jelly Bean right before releasing the completely new OS in May, it would seem that the next version of Android will be 4.3, still Jelly Bean. To add onto this, we know that new versions of Android do not get official code-names until they are several weeks away from being released.
Google announced awhile ago that they would slow down major releases so as to give developers and OEMs the ability to work with the code to make it better. If they released completely new code each year, developers would have to redesign their applications and OEMs would spend even more time trying to adapt the code for their phones.
Anyone disappointed about this news? Personally, as long as Android gets even better (as it always is after each update), I do not mind what Google releases.
