android - android gradle脚本构建后如何自动将APK放入 Assets 中

Question

我正在使用 DexClassLoader 来动态加载类，现在，我需要每次都将 APK 文件复制到 Assets 文件夹中。有没有办法自动添加到android gradle脚本谢谢

Answer 1

您可以使用 python 来完成此操作，同时确保您在执行此操作之前已经安装了 python。

在您的根项目中创建一个 python 文件。

build.py

import subprocess
import shutil
import os
import sys

# Call this function to build the apk via gradle.
def build_cmd():

    # This will build your debug apk.
    buildProject = "gradlew.bat clean --profile --recompile-scripts --offline --rerun-tasks assembleDebug";

    # If you want to build a release apk use this instead.
    # buildProject = "gradlew.bat clean --profile --recompile-scripts --offline --rerun-tasks assembleRelease -Pandroid.injected.signing.store.file=" + os.path.abspath("store_key.jks") + " -Pandroid.injected.signing.store.password=pass123 -Pandroid.injected.signing.key.alias=key_alias -Pandroid.injected.signing.key.password=pass123"

    # As of Python 3 use run() instead of call() function
    # https://docs.python.org/3/library/subprocess.html#older-high-level-api
    subprocess.run(buildProject, shell=True)

# Call this function to move the builded apk to your desire directory.
def moveDir():
    # Get the generated apk
    apk_path = "./app/build/outputs/apk/debug/app-debug.apk"

    # apk will rename and move to asset directory
    shutil.move(apk_path, "./app/src/main/assets/app-debug.apk")


if __name__ == '__main__':

    build_cmd()
    moveDir()

然后在终端运行build.py

python build.py

然后等待 gradle 任务完成。

编辑:

因为一些成员在这个项目上没有python环境而不是在python中使用脚本尝试在你的app/build.xml中添加一些任务。渐变

android {

    // Some stuffs of yours....

    task copyAPKtoAsset(type: Copy) {
        from "/build/outputs/apk/debug/app-debug.apk", "/build/outputs/apk/release/app-release.apk"
        into "/src/main/assets/"
    }

    afterEvaluate {
        packageDebug.finalizedBy(copyAPKtoAsset)
    }
}

构建您的项目并在之后检查您的assets 目录。
