Sony have made the Android M developer preview available on several of its Xperia devices that are listed as part of their Open Device programme.
The list of Xperia devices in the programme are Xperia Z3, Xperia Z3 Compact, Xperia Z3 Tablet Compact, Xperia Z2, Xperia Z2 Tablet, Xperia Z1, Xperia Z1 Compact, Xperia Z Ultra, Xperia E3, Xperia M2, Xperia T2 Ultra, and Xperia T3.
However, Sony's new flagship Xperia Z3+, which is also known as the Z4 in Japan, is not among the devices that will be able to feature the developer preview.
Even though Android M is still in development, several new features have been installed and updated within the new operating system which Sony now wants developers to preview and build apps accordingly.
For example, Android M will bring in a new permissions system through which users will be able to manage app permissions directly during runtime. New apps build for Android M will need to be consistent with this feature, which is why developer previews are so important.
This is the first time that developers will be able to preview Android M on devices other than Google's Nexus ones. So far, other major Android players like HTC, Samsung, Motorola and LG have not released any developer previews of the new operating system.
What benefit Sony will personally derive out of this exercise is difficult to tell, but given some of the gadgets in their Open Device programme are two to three years old, Sony may try and evaluate if they will be able to carry and sync with the Android M platform.
