Android Studio中的GUI方式

Have the Android app part of the React Native app open in Android Studio (this just means opening the android folder of your react-native project with Android Studio) Go to the "Build" tab at the top Go down to "Build Bundle(s) / APK(s)" Then select "Build APK(s)" This will walk you through a process of locating your keys to sign the APK or creating your keys if you don't have them already which is all very straightforward. If you're just practicing, you can generate these keys and save them to your desktop. Once that process is complete and if the build was successful, there will be a popup down below in Android Studio. Click the link within it that says "locate" (the APK) That will take you to the apk file, move that over to your android device. Then navigate to that file on the Android device and install it.

第一个

cd android

然后运行

./gradlew installRelease

最后你将能够在这里找到apk。

Project\android\app\build\outputs\apk\release\app-release.apk

你应该使用android studio来完成这个过程。这样更简单。但是首先在react原生应用目录下运行这个命令:

对于react-native的更新版本(例如:React原生0.49.0等等…)

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

对于react-native的旧版本(0.49.0及以下)

react-native bundle --platform android --dev false --entry-file index.android.js   --bundle-output android/app/src/main/assets/index.android.bundle   --assets-dest android/app/src/main/res/

然后使用android studio在你的react原生应用目录中打开“android”文件夹，它会要求升级gradle和其他一些东西。去build->生成签名APK，并按照那里的指示。这真的很直接。

执行如下命令:

react-native run-android --variant=release

注意——variant=release仅在设置了签名时可用 使用cd android && ./gradlew assemblerrelease。

进入工程目录，执行如下命令:

cd android && ./gradlew assembleRelease

不使用dev-server生成调试APK

如果你真的想生成一个调试APK(用于测试)，可以在没有开发服务器的情况下运行，这里是我对另一篇类似文章的回答的链接，这可能会对你有帮助。 https://stackoverflow.com/a/65762142/7755579

你所要做的就是:

编辑/ app / android构建gradle。

project.ext.react = [
    ...
    bundleInDebug: true, // add this line
]

在项目的根目录下运行此命令

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

然后，在/android文件夹内运行。/gradlew assembleDebug (Mac或Linux)或gradlew assembleDebug (Windows) 如果构建失败，我建议您从Android studio构建应用程序
