What is the difference between arm64-v8a and armeabi-v7a and armeabi

v7aandv8aThe difference arm64-v8a,armeabi-v7aand armeabi are different architecture types for Android applications. arm64-v8a is an application for the 64-bit ARM architecture, suitable for devices that support 64-bit processors, providing higher performance and better memory management. armeabi-v7a is an application for the 32-bit ARM architecture, suitable for most modern Android devices, with good compatibility and performance. armeabi is an older 32-bit ARM architecture that has been gradually replaced by armeabi-v7a. Therefore, the choice of which architecture to use depends on the processor type and performance requirements of the target device. When developing Android applications, you need to choose the appropriate build type according to the architecture of the target device to ensure that the application runs properly and performs well on a variety of devices.

For example: Hisense TV cannot be installedtvbox The main reason is that Hisense TVs use v7a (7th generation and above) 32-bit ARM processors, while TVBox currently only supports 5th and 6th generation 32-bit ARM processors. TVBox currently does not have installation packages for v7a and v8a, which makes it impossible to install TVBox on some TVs using 7th and 8th generation processors.

Sometimes there are several options for downloading software packages, including arm64-v8a, armeabi-v7a, armeabi, x86_64, etc. If you don't know what they mean, randomly choosing to download may result in the software not being installed. The following is an introduction to relevant knowledge.

From these names, you can probably guess that it is related to 32-bit or 64-bit software, which is partly true. To be more precise, arm64-v8a and armeabi-v7a represent the corresponding ABI (Application Binary Interface) of the mobile phone processor and the instruction set it supports.

1. What does arm64-v8a mean?

arm64-v8a stands for the ABI for the 8th generation 64-bit ARM processors. Specifically, it refers to processors that support the ARM 64-bit architecture, which is commonly used in modern high-end mobile phones and tablets. If your device supports the arm64-v8a ABI, then you can install and run applications compiled for this processor architecture.

2. What does armeabi-v7a mean?

armeabi-v7a refers to the ABI for 32-bit ARM processors of the 7th generation and above. Specifically, it refers to processors that support the ARMv7 architecture, which are typically used in older phones and tablets. If your device supports the armeabi-v7a ABI, then you can install and run applications compiled for this processor architecture.

3. How to confirm which ABIs are supported by the phone?

To confirm which ABIs your phone supports, follow these steps:

1. Install AnTuTu Benchmark software (or other similar software) on your phone.
2. Open AnTuTu Benchmark software and find "My Device" or similar option.
3. Look for the "CPU" or "Processor" column in "My Device".
4. Under the "CPU" or "Processor" column, you will see a list of supported ABIs listed, including arm64-v8a, armeabi-v7a,x86-64 wait.

This way you can easily check which ABI your phone supports. If you don't want to install software, you can also use ADB commands to queryABI supported by the phone.

4. How to use ADB command to query the ABI supported by the phone?

To use ADB commands to query the ABI supported by your phone, follow these steps:

1. First, make sure your phone is connected to your computer and the environment variables for the ADB command have been configured.
2. Open Command Prompt (Windows) or Terminal (Mac, Linux).
3. Type the following command and press Enter:

adb shell getprop ro.product.cpu.abi

4. After executing the above command, you will see the supported ABIs listed in the command line, such as arm64-v8a, armeabi-v7a, x86-64, etc.

This way you can use ADB commands to query the ABI supported by your phone without installing additional software.

Summarize

The above introduces different options that you may encounter when downloading software packages, such as arm64-v8a, armeabi-v7a, etc. These options represent different mobile phone processors and instruction sets. In order to ensure that the software can be installed correctly, you need to understand the ABI type supported by the mobile phone. You can query the ABI supported by the mobile phone through Antutu benchmark software or use ADB commands. The choice of ABI is related to the compatibility of the mobile phone processor. A 64-bit processor can be compatible with 32-bit software, but not vice versa.
