• 代碼如下

• 注意：只能在有系統許可權下使用，也就是在AndroidManifest.xml裡面有

  <?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">

  　　

• 需要有許可權

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

  　　

• 所以這就決定了只能再自己有源碼不是定製android系統的裝置上有效果
