1，在项目根目录下创建一个名为package.json的空文本文件，然后填入以下内容：
{
"name": "MyReactNativeApp",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node node_modules/react-native/local-cli/cli.js start"
},
"dependencies": {
"react": "16.0.0-alpha.6",
"react-native": "0.44.3"
}
}
2，执行
$ npm install

3,加入react依赖dependencies {
...
compile "com.facebook.react:react-native:+" // From node_modules.
}

4,项目的build.gradle中加入
allprojects {
repositories {
...
maven {
// All of React Native (JS, Android binaries) is installed from npm
url "$rootDir/../node_modules/react-native/android"
}
}
...
}

5,配置权限
接着，在 AndroidManifest.xml 清单文件中声明网络权限:

<uses-permission android:name="android.permission.INTERNET" />
如果需要访问 DevSettingsActivity 界面（即开发者菜单），则还需要在 AndroidManifest.xml 中声明:

<activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />

6, 创建index.android.js

7，请确保你在开发版本中有打开悬浮窗(overlay)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (!Settings.canDrawOverlays(this)) {
Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, OVERLAY_PERMISSION_REQ_CODE);
}
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == OVERLAY_PERMISSION_REQ_CODE) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (!Settings.canDrawOverlays(this)) {
// SYSTEM_ALERT_WINDOW permission not granted...
}
}
}
}

8， 如果报Could not get BatchedBridge, make sure your bundle is packaged correctly

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

9，如果报Conflict with dependency 'com.google.code.findbugs:jsr305'](http://blog.csdn.net/anyway1919/article/details/53469318)
android {
configurations.all {
resolutionStrategy.force 'com.google.code.findbugs:jsr305:1.3.9'
}
}

10,执行npm start

11,正常的run android

12,如果连接不上检查代理是否关闭，重设置ip host:8081
