react-native init Test 创建一个Test项目
npm install ：安装依赖库
react-native run-android：运行项目

compile 'com.github.barteksc:android-pdf-viewer:2.7.0'
WebStorm 卡在 react-native-pdf-view没反应。
react-native-pdf-view的Android版本降低
// compile 'com.github.barteksc:android-pdf-viewer:+'
compile 'com.github.barteksc:android-pdf-viewer:2.7.0'
npm config set registryhttps://registry.npm.taobao.org 一直卡着。
可以先升级node.js的最新版，sudo -n 。npm install 升级后再改回7.8.0.
Resolving dependencies ':react-native-pdf-view:_debugPublish'卡住
可以直接单独下载react-native-pdf-view

解决
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
可以在打包命令后面添加--stacktrace，控制台会输出更多问题信息。
打包添加更多日志 ： gradle assembleRelease --stacktrace
最后发现是没配置NDK。在项目的local.properties的文件中添加NDK的路径。
如何将当前版本的ReactNative 降级 ？
npm install --save [email protected]
node 的版本安装
确保nvm安装
nvm install 7.8.0
nvm use 7.8.0
要外围
sodu n 8.3.0
刷新页面
adb shell input keyevent 82
手机热加载
ip:8081
查询console日志
adb logcat *:S ReactNative:V ReactNativeJS:V
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/
测试
react-native run-android --flavor=Flavors_testDebug -- appId=com.evergrande.qms.test
生产
react-native run-android --flavor=Flavors_defaultDebug
打生产包
gradle assembleRelease

- 将react-native-pdf-view 的compileSdkVersion，buildToolsVersion，buildToolsVersion，targetSdkVersion设置和主工程相同
- 并修改主工程的,设置相同的版本编译库，防止其他库使用的版本不同。

Provided schema version 220 is less than last set version 222
修改realm的schemaVersion: 222

修改 minSdkVersion 15 为 minSdkVersion 16
还有个测试方法报错
直接删掉

依赖包多了很慢加载很久。
Resolving dependencies ':app:_flavors_defaultDebugApk' >
1、修改加载慢的包中的react-native 版本。
compile "com.facebook.react:react-native:0.44.0" // From node_modules
2、 可能的原因是项目的下载依赖库有问题,有些仓库地址访问不到，删除掉。
allprojects {
repositories {
// mavenLocal()
// maven { url "https://maven.google.com" }
// maven { url "https://jitpack.io" }
jcenter()
maven {
// All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
url "$rootDir/../node_modules/react-native/android"
}
}
