Google has introduced a new software development kit for the Android 2.2 operating system known as Froyo.

In a July 8 blog post, Google engineer and Android SDK Tech Lead Xavier Ducrohet, said Google initially released an Android 2.2 SDK at the Google I/O developer conference in May, but the company has created subsequent builds of the software since then.

According to Durochet's post: "The Android 2.2 SDK that was released at Google I/O contained a preview of the Froyo system image and today, we are releasing an update to bring it into sync with the system image pushed to Nexus One devices."

Meanwhile, in a separate July 8 blog post, Suchi Amalapurapu, a Google engineer working on Android 2.2, said the Froyo release supports application installation on external storage devices like the SD card. "This should give users room for many more apps, and will also benefit certain categories, like games, that need huge assets," he said.

Amalapurapu added that the "'Manage Applications' screen in the Settings app now has an -On SD Card' tab. The sizes listed in Manage Applications only include the space taken by the application on internal storage."

Moreover, SD-card installation "is an optional feature on Android 2.2," Amalapurapu said. He added that SD card installation "is under the control of the developer not the user, and will not affect any applications built prior to Android 2.2."
