初始化RN项目后,经测试在模拟器上能正常跑起来,我的手机不行,经一番搜索现将解决方案备份
手机出错信息如下

进入项目根目录 将项目\android\build.gradle 文件中的com.android.tools.build:gradle:2.2.3，改成1.2.3
运行
控制台再次报下面错误
<pre>
Build file '/home/meijun/RN20170724/AwesomeProject/android/app/build.gradle' line: 1
- What went wrong:
A problem occurred evaluating project ':app'.
Failed to apply plugin [id 'com.android.application']
Gradle version 2.2 is required. Current version is 2.14.1. If using the gradle wrapper, try editing the distributionUrl in /home/meijun/RN20170724/AwesomeProject/android/gradle/wrapper/gradle-wrapper.properties to gradle-2.2-all.zip
- Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
</pre>
根据提示
进入AwesomeProject\android\gradle\wrapper\gradle-wrapper.properties，这个文件， 改为如下
<pre>
distributionUrl=https://services.gradle.org/distributions/gradle-2.2-all.zip
</pre>
再次运行,即可
2,手机无法显示RN Dev setting 选项
请检查是否开启了悬浮窗权限,(rn官网只填了小米,其实我的魅族也限制了弹窗啊啊啊啊啊啊,花了我好久找这个问题)
