On April 6, OPPO, vivo and xiaomi, the main mobile phone manufacturers of the ITGSA Mobile Intelligent Terminal Ecosystem Alliance, jointly announced an announcement for App developers.
The announcement pointed out that from April 2022, when oppo, vivo, and Xiaomi app stores are newly listed, 32-bit app packages will not be allowed to be listed separately, and compatible or dual package uploads can be supported, while game apps are temporarily unrestricted.
Friends who know the computer know that in the past, when installing the Windows system, they needed to know whether the computer was 32-bit or 64-bit.
If you choose incorrectly, the result will be problems such as system performance degradation, incompatibilities, installation failures, and so on.
The reason for this problem is that at that time, the development of hardware was limited, and some low-configuration computers were basically out of touch with 64-bit systems.
In recent years, a few years after mobile phone chips have entered the multi-core era, a 64-bit application revolution has also developed rapidly in the Android ecosystem.
From 32-bit to 64-bit
Before talking about Android, let's talk about Android's "old rival" - Apple.
In fact, as early as 2017, Apple released the iOS 11 system, which completely canceled 32-bit applications.
Apple told developers that if the application package is not 64-bit, it will not be available on the App Store, and applications that have been listed will also be removed if they have not yet been adapted to 64-bit.
This plan began with iOS 7 in 2013, and Apple completed the iteration from 32-bit to 64-bit in just 4 years.
Why did Apple use 64-bit apps long ago, and Android is only acting now?
In fact, Google's pace of opening up the Android 64-bit era is only a year behind Apple's.
Because the first chip to support 64-bit (Qualcomm Snapdragon 808) and the system (Android 5.0) actually came out in 2014.
But by 2022, after years of smartphone development, 32-bit apps are still popular on Android.
For example, many banking, government and enterprise apps.
The reason is that in addition to the openness of the Android system, a large number of old versions and old models also occupy half of the Android ecology.
At the same time, the third-party developers of Android applications are also scattered, so the pace of implementation of 64-bit in the Android camp has always been difficult to unify.
Why the shift to 64-bit?
As for why we switched to 64-bit, it's simple, because 32-bit is no longer suitable for the current environment.
Here's the difference between 32-bit and 64-bit.
According to results from Arm lab tests, 64-bit computing on smartphones is more than 90% faster when compressing files and nearly 80% faster when decompressing than 32-bit computing.
In terms of energy consumption, 64-bit applications have better power performance than 32-bit.
Compared to 32-bit, mainstream mobile processor architectures achieve 13.2% to 35.2% energy efficiency gains in 64-bit environments.
The iPhone now runs on 64-bit apps, which is one of the reasons why the iPhone is smoother than the Android phone.
The specific deep principle is more complicated, you just need to remember that 64-bit applications run more efficiently than 32-bit applications.
How do I see if an app is 32-bit or 64-bit?
Here you need to use a piece of software - LibChecker. After the installation, Guo took a look at it, and there are still many apps in the mobile phone that are 32-bit.
So how do I swap a 32-bit app for a 64-bit app? In other words, where do I download 64-bit apps?
First, try to find 64-bit apps with the phone's own app store, and then upgrade.
For example, the Xiaomi App Store has opened a 64-bit application area for the Xiaomi Mi 12 and Xiaomi Mi 12 Pro series, and the OPPO App Store has fully embraced 64-bit applications.
Secondly, those who have the conditions can go to the Google Play Store to upgrade.
Nowadays, under the joint call of OPPO, vivo, millet and other domestic manufacturers, it is believed that the speed of entering the 64-bit era will be further accelerated, and users can feel a smoother and smoother use experience.
