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。

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.

参考react-native关于生成签名APK的官方文档

原生生成签名APK

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
