初始化项目安装react-native-camera会遇到各种版本问题，逐个更改
打release包一直报 android/app/build/intermediates/res/merged/release/drawable-hdpi/node_modules_reactnavigation_src_views_assets_backicon.png: error: uncompiled PNG file passed as argument. Must be compiled first into .flat file..
暂时解决方法： In your gradle.properties file add following lines: classpath 'com.android.tools.build:gradle:3.0.0' distributionUrl=https://services.gradle.org/distributions/gradle-4.1-all.zip android.enableAapt2=false
Could not resolve all files for configuration ':react-native-vector-icons:classpath'.
Could not resolve com.android.tools.build:gradle:2.3.+. 在react-native-vector-icons/build.gradle添加： maven { url 'https://maven.google.com/' name 'Google' }
统一ui: 背景黄色: #fc0 按钮背景: #d40511 subTitle: #969696 title: #333
