Tip: 1：动态权限是Android6.0以上(API 23||23+)才有的如果发现每次请求权限返回的都是true,将/app/build.gradle compileSdkVersion,buildToolsVersion,targetSdkVersion都调整到23及以上版本. 2：每次请求都是false,原因可能是没有在AndroidManifest.xml 里面注册权限。 3：如果已经同意一次权限请求下次在使用该权限时不会提示，只有拒绝后才会每次都弹出提示框。 android 原生权限工具： https://github.com/wuyunqiang/ReactNativeUtil/issues/54
