颤动生成的3个APK之间有什么区别? [英] What is the difference between 3 APKs generated from flutter?

问题描述

我需要了解Android设备的体系结构，以及为什么在使用时会生成三种不同类型的APK:

I need to understand the Android device architecture and, Why there is three different types of APKs are generated when I use:

flutter build apk --split-per-abi.

当我使用

flutter build apk

我得到了一个名为fat APK的大型APK文件，其中包含该应用程序的3个版本.

I get a large APK file called fat APK contains the 3 versions of the app.

推荐答案

flutter build apk为您带来了很大的apk，因为

flutter build apk gives you large apk because,

flutter build apk会生成一个胖APK，其中包含为所有目标ABI编译的代码.此类APK的大小要大于拆分后的对应文件，导致用户下载不适用于其设备架构的本机二进制文件.

flutter build apk results in a fat APK that contains your code compiled for all the target ABIs. Such APKs are larger in size than their split counterparts, causing the user to download native binaries that are not applicable to their device’s architecture.

--split-per-abi产生两个APK文件:

---

--split-per-abi results in two APK files:

(flutter build命令默认为--release.)

(The flutter build command defaults to --release.)

<app dir>/build/app/outputs/apk/release/app-armeabi-v7a-release.apk
<app dir>/build/app/outputs/apk/release/app-arm64-v8a-release.apk

其中armeabi-v7a是32位设备，而arm64-v8a是64位设备.

Where armeabi-v7a for is 32-bit devices and arm64-v8a for 64-bit devices.
