Although the hardware architecture of the Raspberry Pi is similar to that of most Android devices, there is no official edition of the mobile operating system available for the popular single-board computer. That could be about to change, however, with indications emerging that an Android build for the Raspberry Pi is being considered.
A folder assigned to the Raspberry Pi 3 has been spotted in the Android Open Source Project. Although the folder is currently empty, its existence does offer some evidence that consideration has been given to releasing Android for the Raspberry Pi 3.
There have been a number of unofficial attempts, such as Razdroid, to create a build of Android for the Raspberry Pi. But if official support comes from Google, interest from developers and hobbyists is likely to increase considerably.
