we could see more Material You on Custom ROMs

Google is loosening up on its Material You requirements for Android 12 and 13. This should especially help custom ROM developers working on the new design of the operating system.

With the arrival of Android 12, Google unveiled Material You, new interface design guidelines. A design best known for Monet, the function that allows you to adapt the colors of the system according to the wallpaper chosen. However, in February, we learned that Google was going to require Material You to be present on Android 12 smartphones if they wanted to take advantage of Google Mobile Services. Without this license, no Play Store or Google services, which means that this condemns the phone if it is intended for the general public (just look at Huawei). Apparently this requirement no longer exists and would have simply been removed. In fact, this should help developers work with Material You on custom ROMs more.

No Material You, no Google services

The problem is that Google had established a list of models authorized to take advantage of the libraries it provides to application developers. Developers who could not then optimize their applications for their custom ROMs: they could only test their applications on certain smartphones, which Google had validated.

According Android Police, this whitelist came from a rather logical reasoning. The American media recalls that “Material You was designed to ensure customization does not interfere with accessibility “. This with the aim ofensure that system-generated colors do not make buttons or text difficult to read“. However, “nothing stops smartphone makers from making bad and stupid changes to android“. In reality, this does not prevent manufacturers from deploying Material You, but aims to prevent them from modifying it in a way that would affect this accessibility.

The end of this Google requirement

It’s a “reliable source» ofAndroid Policewhich tells the media that “Google dropped its Material You requirement for Android 12 GMS licenses“. Only specific standards remain for smartphones that actually implement it.

For Android 13 phones and ROMs, this list of allowed models would simply be removed. On this version of the operating system, Google “plans to create a series of automated tests to verify that Material You is implemented correctly“. Tests that will not happen on Android 12, since on this version the giant says it is working with manufacturers individually.

However, as the outlet notes, “custom ROMs cannot implement Material You on Android 12 if the manufacturer of the device they are developing the software for has not been approved“. Dropping this requirement from Google is therefore likely to help Android 12 ROM developers work on Material You.
