如何配置React Native Android库以使用npm安装的react-native? [英] How to configure react native android library to use npm installed react-native?
问题描述
我正在编写一个android库，需要调用ReactInstanceManager.onHostResume，我的build.gradle文件内容是:
I'm writing an android library, need to call ReactInstanceManager.onHostResume, my build.gradle file content is:
apply plugin: 'com.android.library'
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
minSdkVersion 16
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile "com.facebook.react:react-native:+"
}
我使用 npm install --save react-native-mylib 将其安装到示例项目中，然后使用 react-native run-android 编译该项目导致的错误:
I installed it into an example project with npm install --save react-native-mylib, and then compile the project with react-native run-android, some errors caused:
MyModuleActivity.java:107: error: cannot find symbol
mReactInstanceManager.onHostPause();
^
symbol: method onHostPause()
location: variable mReactInstanceManager of type ReactInstanceManager
我试图找到已安装的本机库:
I try to find installed react-native libraries:
find . -iname "*.jar"
...
./node_modules/react-native-mylib/android/build/intermediates/exploded-aar/com.facebook.react/react-native/0.20.1/jars/classes.jar
./node_modules/react-native-mylib/android/build/intermediates/exploded-aar/com.facebook.react/react-native/0.20.1/jars/libs/infer-annotations-1.5.jar
...
似乎它从maven安装了react-native@0.20.1，此版本的react-native尚未启用HostPause方法.
Seems it installed react-native@0.20.1 from maven, this version of react-native hasn't onHostPause method.
在另一个链接了某些库的项目中找到库，它们都链接了react-native的旧版本:
Find libraries in another project that linked some libraries, they are all linked old version of react-native:
$ find . -iname "*.jar" | grep com.facebook.react

问题:如何配置它以正确使用node_modules/react-native/android?
已解决，只需将正确的存储库设置为:
repositories {
mavenLocal()
jcenter()
maven {
// All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
url "$projectDir/../../../node_modules/react-native/android"
}
}
推荐答案
不久前也已解决...我使用 react-native-create-library 创建了一个库.maven提供的最新版本是0.20.1，对于今天的react-native版本而言，它有些旧.所以我将所需的RN版本安装到了库的node_modules文件夹中
Resolved a while ago as well... I created a library using react-native-create-library. The latest version maven provides is 0.20.1, which is a little old for today's react-native versions. So I installed the RN version I needed into the node_modules folder of my library
npm install react-native@0.46.1
npm install react-native@0.46.1
在build.gradle中
And in build.gradle
repositories {
maven {
// All of React Native (JS, Android binaries) is installed from npm
url "$rootDir/../node_modules/react-native/android"
}
jcenter()
}
//
dependencies {
compile 'com.android.support:appcompat-v7:23.0.1'
compile "com.facebook.react:react-native:+"
}
这样，您无需将库保留在主项目中即可构建和检查语法.
This way you don't need to keep your library inside of your master project in order to build and check your syntax.
