Sony is known to be one of the leading OEMs to support the third-party Android development community for its devices. This is evident from the AOSP for Xperia program from the company, where it offers a stock AOSP build of the latest version of Android for its selected devices.
As a part of its Open Device program, Sony has now provided developers and advanced users with all the necessary software binaries and instructions to get the Developer Preview of Android M up and running for certain Xperia devices. Sony has also uploaded a video of the Developer Preview of Android M running on the Xperia Z3 Compact:
The supported list of devices are as follows:
The company has not made pre-built ROMs available for the devices above, but it is just a matter of time before a developer creates an Android M based ROM for all the devices supported under the Open Device program from Sony. The ROM is only meant for developers for their testing purposes, and cannot be used as a daily driver since the camera and modem functionality are broken.
