在react-native中构建签名发布APK的正确方法是什么？

我不确定自己在做什么是正确的方法，还是错过了我所做的某些步骤或太多的步骤。我可以从教程，论坛和示例的各种发现中检索到构建APK的方式。同样，我仍然不确定我的构建方式。

我在./android/app目录中有生成的密钥库文件，以下是我找到并尝试的结果，但我不知道它们之间的区别：

第1步：

> cd android
> gradlew clean
> gradlew assembleRelease

第2步：

> react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle
> cd android
> gradlew assembleRelease

步骤3：

> react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/
#Go to ".\android\app\src\main\res" and delete all *drawable-xxxx* and *raw* folder if exist
> cd android
> gradlew assembleRelease -x bundleReleaseJsAndAssets

步骤4：

> npx jetify
> cd android
> gradlew clean
> gradlew assembleRelease

步骤5：

# Go to ./android/app/src/main/assets/ and remove `index.android.bundle` file
> react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res
> cd .\android\app\src\main\res && if exist "drawable-hdpi" rmdir "drawable-hdpi" /q /s && if exist "drawable-mdpi" rmdir "drawable-mdpi" /q /s && if exist "drawable-xhdpi" rmdir "drawable-xhdpi" /q /s && if exist "drawable-xxhdpi" rmdir "drawable-xxhdpi" /q /s && if exist "drawable-xxxhdpi" rmdir "drawable-xxxhdpi" /q /s && if exist "raw" rmdir "raw" /q /s
> cd..\..\..\..\..\android
> gradlew assembleRelease -x bundleReleaseJsAndAssets

另一方面，我还创建了自己的批处理文件，以使该版本成为APK。该文件将在项目根目录文件夹之前运行一个文件夹。

build-react-native-release.bat：

@echo off
:: BatchGotAdmin
:-------------------------------------
REM  --> Check for permissions
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"

REM --> If error flag set, we do not have admin.
if '%errorlevel%' NEQ '0' (
    echo Requesting administrative privileges...
    goto UACPrompt
) else ( goto gotAdmin )

:UACPrompt
    echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
    set params = %*:"=""
    echo UAC.ShellExecute "cmd.exe", "/c %~s0 %params%", "", "runas", 1 >> "%temp%\getadmin.vbs"

    "%temp%\getadmin.vbs"
    del "%temp%\getadmin.vbs"
    exit /B

)

if not '%choice%'=='' (
    if exist %choice% (

        CD %choice%
        goto performbuild
    )
)
echo Invalid directory name!
goto startAgain

cd %currentFolder%%choice%
:choiceOpt
set /P answ=Build complete. Do you want to rebuild again[Y/N]?
if /I "%answ%" EQU "Y" goto :performbuild
if /I "%answ%" EQU "N" goto :justexit

创建的这个APK.\android\app\build\outputs\apk\release是我们将传递给APK进行验证的APK吗？
