react-native 配置在安卓模拟器上运行

1. 在全局路径下修改环境变量

vim ~/.bash_profile

# Setting PATH for Python 3.6
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.6/bin:${PATH}"
#如果你不是通过Android Studio安装的sdk，则其路径可能不同，请自行确定清楚。
export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools
export PATH=$PATH:$ANDROID_HOME/emulator
export GRADLE_HOME=/Applications/Android\ Studio.app/Contents/gradle/gradle-5.1.1
export PATH=${PATH}:${GRADLE_HOME}/bin
export ELECTRON_MIRROR="https://npm.taobao.org/mirrors/electron/"

2. 在android/ 下增加：local.properties文件

sdk.dir=/Users/liuwei/Library/Android/sdk
ndk.dir=/Users/liuwei/Library/Android/sdk/ndk-bundle

3. 将android/app/build.gradle文件中的implement改为compile

4. 另外gradle是负责编译的，参考https://blog.csdn.net/u013553529/article/details/55011602

5. react-native run-android
