针对于android app的各种设置的相关知识点整理一下

api Settings

系统api settings 的源码位于 android.provider.Settings 包下，里面有各种关于app需要跳转到手机去设置的权限，这里列出一些常用的权限（官方说明文档）：

像跳转到wifi， 网络，定位等设置界面，就是intent 不同而已，所以我们只需要记住常用的或者去查询，像app的设置界面，开发者设置界面等等。而跳转的代码可以用公式表达为

Intent intent = new Intent("某个intent");
startActivityForResult（intent ，code）；
