[移动开发]代码设置桌面壁纸或者屏保

• 今天公司让弄一个把图片和视频设置为屏保和壁纸的功能，刚开始在网上找了很多资料 设置壁纸很好实现 一句话就可以了，这个可以参考这个人写的代码 图片视频设置为壁纸 但是实现设置锁屏屏保就不大好实现了，后来想了想 如果能跳转到系统设置壁纸的界面 由用户自己选择设置壁纸 或者 屏保不就行了 于是百度，最后整理出来 有需要的拿走 直接上代码

• 注意 记得加权限
  <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
• 7.0文件路径的问题记得适配 还有就是本地根目录下得有bbb.jpg这个图片文件
• 希望能帮到你！！
