Also based on linux, why is Android inefficient?

Reasons: 1. A JAVA virtual machine is set up on the Android system to support the running of Java applications, and this virtual machine consumes a lot of hardware; 2. The mobile phone manufacturer’s requirements for the Android system Customization and development increase the burden on the Android system, slowing down its running speed and affecting its fluency; 3. Application software is too bloated and homogeneous, which slows down the running speed of Android phones to a certain extent.

#The operating environment of this tutorial: linux7.3 system, Dell G3 computer.

Android is an open source mobile operating system that is widely used around the world and has the largest market share in the world. As we all know, the Android system is developed based on the Linux kernel. Compared with the clean, stable, smooth and other characteristics of Linux, the Android system still appears to be bloated and messy.

So, with the same kernel, why is Linux clean and stable while Android is bloated and smoky?

The upper-layer application system independently constructed by the Android system

Although the Android system is developed based on the Linux kernel, it only uses the Linux kernel and its upper-layer application system All are built completely independently. In this process, the Android system has redefined many things, especially in terms of its running environment.

Back then, when Google started developing the Android system, in order to lower the entry barrier for developers and quickly attract developers to join, it chose the popular JAVA language at the time. However, a JAVA virtual machine must be set up on the Android system to support the running of Java applications, and this virtual machine consumes a lot of hardware.

# Therefore, this design pattern of the Android system causes its fluency and portability to lag behind the Linux operating system.

Customization and development of Android systems by mobile phone manufacturers

Google’s Android system is open source, and any mobile phone manufacturer can build on it Secondary customization and development of the system, such as the current domestic mainstream OPPO mobile phone ColorOS, Xiaomi MIUI and Huawei's emui are all based on the Android system.

However, in the process of system customization and development, driven by profit, merchants often pre-install some specific application software into the system, and most of the pre-installed software cannot be freely uninstalled. of. Such a wave of operations will inevitably increase the burden on the Android system, slow down its running speed and affect its smoothness.

The Android system application ecosystem lacks supervision

One of the fundamental reasons why Apple’s iOS system is smooth is the lack of supervision of system applications and The management and supervision of permissions are in place, and a unified Apple Store is used in the APP installation mode. Users who want to download application software must go through this app store, and all businesses listed in the store have been strictly reviewed by the platform. This move fundamentally eliminates some permission confusion issues.

In contrast, the performance of Android system in this aspect is very confusing.

Due to the lack of unified management of the domestic Android ecosystem, mobile phone manufacturers of major brands are working independently, and due to the open source characteristics of the Android system, the process of installing applications is completely unnecessary. Through the app store, you only need an APk program installation package to install it directly. This gives applications the potential to unleash their will to a large extent, especially in terms of obtaining important permissions such as various message push, address book permissions, and text message reading. This not only slows down the running speed of the Android system, but also creates security risks of personal privacy leakage.

Application software is too bloated and homogeneous

Domestic application software is generally bloated. For example, Alipay covers almost every application scenario in life, and even You can also play games through Alipay. In reality most of these features are unnecessary. Domestic APPs wish that one software could take care of all your food, drinks and peeing.

In this case, if a large number of software are installed, there will inevitably be a large number of duplicate application functions in the mobile phone. This will also slow down the running speed of Android phones to a certain extent.
