如何生成一个可以在没有带反应原生的服务器的情况下运行的apk？ [英] How can I generate an apk that can run without server with react-native?

问题描述

我已经构建了我的应用程序，我可以在我的本地模拟器上运行它（也可以通过更改调试服务器在同一网络中的我的Android设备上运行）。

I've built my app, I can run it on my local simulator (and also on my android device within the same network by changing debug server).

但是，我想构建一个apk，我可以发送给没有访问开发服务器的人，我希望他们能够测试应用程序。

However, I want to build an apk that I can send to someone without access to development server and I want them to be able to test application.

我看到有一个部分在文档的iOS部分使用脱机捆绑包。但我无法弄清楚如何为Android做同样的事情。这可能吗？如果是这样，怎么做？

I see there is a section Using offline bundle on iOS section of the documentation. But I couldn't figure out how to accomplish same for android. Is this possible? If so, how?

更新：关于这个问题的答案（反应原生android无法加载JS包）据说离线包可以从开发服务器下载。但是当我从开发服务器获取包时，无法加载图像文件。

UPDATE: On the answer to this question (react native android failed to load JS bundle) it is said that offline bundle can be downloaded from development server. But when I obtain the bundle from development server the image files can't be loaded.

推荐答案

按照Aditya Singh的回答生成（没有签名）apk不会安装在我的手机上。我必须使用说明生成一个签名的apk 这里。

Following Aditya Singh's answer the generated (unsigned) apk would not install on my phone. I had to generate a signed apk using the instructions here.

以下对我有用：

$ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000

将 my-release-key.keystore 文件放在 android / app
下项目文件夹中的目录。然后编辑文件
〜/ .gradle / gradle.properties 并添加以下内容（用正确的密钥库密码替换****
，别名密钥密码）

Place the my-release-key.keystore file under the android/app directory in your project folder. Then edit the file ~/.gradle/gradle.properties and add the following (replace **** with the correct keystore password, alias and key password)

MYAPP_RELEASE_STORE_FILE=my-release-key.keystore
MYAPP_RELEASE_KEY_ALIAS=my-key-alias
MYAPP_RELEASE_STORE_PASSWORD=****
MYAPP_RELEASE_KEY_PASSWORD=****

如果你'重新使用MacOS，您可以使用此处而不是以明文形式存储它。

If you're using MacOS, you can store your password in the keychain using the instructions here instead of storing it in plaintext.

然后编辑app / build.gradle并确保以下内容（可能需要添加visaConfigs signingConfig的部分）：

Then edit app/build.gradle and ensure the following are there (the sections with signingConfigs signingConfig may need to be added) :

...
android {
    ...
    defaultConfig { ... }
    signingConfigs {
        release {
            if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
                storeFile file(MYAPP_RELEASE_STORE_FILE)
                storePassword MYAPP_RELEASE_STORE_PASSWORD
                keyAlias MYAPP_RELEASE_KEY_ALIAS
                keyPassword MYAPP_RELEASE_KEY_PASSWORD
            }
        }
    }
    buildTypes {
        release {
            ...
            signingConfig signingConfigs.release
        }
    }
}
...

然后运行命令 cd android&& ./gradlew assembleRelease ，

For Windows 'cd android'然后运行 gradlew assembleRelease 命令，在 android / app / build / outputs / apk / app-release.apk 签名 apk >

For Windows 'cd android' and then run gradlew assembleRelease command , and find your signed apk under android/app/build/outputs/apk/app-release.apk
