• 注意：只能在有系统权限下使用，也就是在AndroidManifest.xml里面有

  <?xml version="1.0" encoding="utf-8"?>
  <manifest xmlns:android="http://schemas.android.com/apk/res/android"
      android:sharedUserId="android.uid.system"
      package="com.jiangdg.usbcamera">
  

  　　
• 需要有权限

  <uses-permission android:name="android.permission.EXPAND_STATUS_BAR"/>
  

  　　

• 所以这就决定了只能再自己有源码不是定制android系统的设备上有效果
