Android 2.4 will retain the "Gingerbread" codename and bridge compatibility with "dual-core" apps written for Android 3.0 Honeycomb, according to rumors attributed to a source at Viewsonic. The reports from Pocket-Lint also suggest that version 2.4 will debut in April on Viewsonic's ViewPad 4.

"According to our source, the release date of version 2.4 has been brought forward to ensure that dual-core apps designed for Honeycomb (v3.0) will be able to work with single-core devices running v2.4. Currently, our man on the inside says that’s not possible with version 2.3 (Gingerbread) hence the need to push to the next iteration and version number, but not change the name. It's most likely to be one of the main reasons we’ve yet to see any major manufacturer gunning to get Android 2.3 handsets out there."

There've been plenty of rumors involving Android 2.4 over the past couple of months. It was snapped on the Xperia Arc at CES, though Sony Ericsson later dismissed this as an error. Videos have also appeared of 2.4 apparently running on a German version of the Nexus S, though so far there's been no official confirmation of Android 2.4's existence.

As ever, though, rumors like this should be taken with a pinch of salt, and launch dates -- especially unannounced and unconfirmed ones -- are always subject to change. [Pocket-Lint]
