title: Where is android.os.SystemProperties?
body: <p>I'm looking at the Android Camera code, and when I try importing <code>android.os.SystemProperties</code>, it cannot be found.</p>
  
  <p>Here is the file I'm looking at:<br>
  <a href="https://android.googlesource.com/platform/packages/apps/Camera/+/eclair-release/src/com/android/camera/VideoCamera.java" rel="noreferrer">https://android.googlesource.com/platform/packages/apps/Camera/+/eclair-release/src/com/android/camera/VideoCamera.java</a></p>
  
  <p>I created a new 2.1 project and tried importing this namespace again, but It still cannot be found. I checked <a href="https://developer.android.com" rel="noreferrer">https://developer.android.com</a> and <code>SystemProperties</code> was not listed.</p>
  
  <p>Did I miss something?</p>
