Developers choose API levels, nothing else.
From developers perspective, API levels mean different set of libraries, meaining there are newer functions or newer variant of the same functions that they need to adapt their code. What happens to the HW platform it not their concern. It is OS developer's concern.

See your picture, API level remains 24 on ARM V7 and V8. It doesn't even matter if the underlaying HW is ARM, I am running many Android apps on my Windows 11 (X86-64) WSA (Windows Subsystem for Android).

My android app development knowledge is rusty haven't done it in ages. But Android apps are compiled to bytecode which are run in ART the Android Run Time a virtual machine. By using ART google can abstract away the hardware. Maybe if you made some native android stuff you might need a specific Arm level but i have never worked with native stuff on android..

That is exactly what Android is. The whole thing about Android is its VM.

Beyond the VM, it is native Linux running on any kind of CPU.

In rough terms, Android = Java, Android Apps = Java applet. The VMs run on any kind of CPU with different instruction sets.

I wonder if this early release is to just greet Raimondo with a big FU

It has to be. I am convinced of that. Although I got no proof.

It is interesting though.

The rumours were that these phones were to be ready by the end of this year, possibly.

Looks like they are ready now. Full 5G Huawei phones. But Raimondo's trip was up in the air, it was not for certain she would come to China.

So who actually manufactured the chips for Huaweio_O? Some said it's Huawei themselves transforming into an IDM (although cooperating tightly but indirectly with SMIC and other partners), but most thought it should just be SMIC's mature N+1 or N+2 process building ~7nm chips (are they not allowed to do any business with Huawei since theoretically they are easily monitored and involves loads of US related tech?)

Domestic photovoltaics use GaN again, with a future production capacity of 1 million sets.​


Transphorm announced that the company's GaN platform will be applied to DAH Solar's photovoltaic micro-inverter.

Transphorm stated in the announcement that their gallium nitride will be used in Daheng Energy's Solar Unit product line . GaN devices can realize smaller, lighter, and more reliable solar energy systems, while also providing energy at lower energy consumption. Higher total power generation. Transphorm also said that the market space of gallium nitride technology in the global photovoltaic field will exceed 500 million US dollars .

Specifically, Daheng Energy's Solar Units will use Transphorm 's 150 mΩ and 70 mΩ GaN devices (in PQFN88 packages) in the DC-DC and DC-AC power stages . SolarUnit mainly has 3 models, the power output is 800 W, 920 W or 1500 W, and the peak efficiency is 97.16%, 97.2% and 97.55% respectively.

Anhui Daheng New Energy Technology Co., Ltd. was established in 2009. Its main business includes: photovoltaic modules, photovoltaic systems, photovoltaic storage systems and other technology research and development, production and manufacturing, as well as power station investment, construction and operation and maintenance services.

According to its official website, Daheng Energy has become one of the top 3 well-known photovoltaic companies in Brazil . In April this year, Xie Shenheng, the founder and chairman of Daheng Energy, said in an interview with the media that their revenue this year will be about 6 billion yuan , and it will exceed 10 billion yuan in the next two to three years.

Before the Spring Festival this year, the main structure of Daheng Energy's Anchao base plant and supporting facilities will be officially capped, and an 8GW TOPCon cell and module production base will be built. The project is also progressing as scheduled, and will realize the production capacity of 1 million sets of the world's first SolarUnit integrated photovoltaic system.
According to "experts say three and a half generations", on May 24 this year, Daheng Energy released the "SolarUnit'Roof + balcony'integrated photovoltaic system solution". SolarUnit adopts integrated design of components and inverters, unique three-chip low-current technology, and applies GaN technology , as well as 32-bit high-speed digital processor, the system conversion efficiency is as high as 97.55 % .​

China has world's largest GaN power semiconductor in Innoscience and Daheng New Eenergy is buying foreign GaN?

China needs to put a stop to Ga export or this kind of nonsense will continue. Having a GaN-based inverter supply chain outside of China is definitely not in China's interest.
