title: ExifInterface.getDateTime and getGpsDateTime is not exist
body: <p>So i was diving through ExifInterface class for android. You can see it here:
  <a href="https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/media/java/android/media/ExifInterface.java" rel="nofollow">https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/media/java/android/media/ExifInterface.java</a></p>
  
  <p>There are methods called getDateTime() and getGpsDateTime(). I wonder why i can't access these methods directly from my project, since it has public access modifier, while i can access other methods like getAltitude(double defaultValue), getAttribute(String tag), etc.</p>
  
  <p>From <a href="https://developer.android.com/reference/android/media/ExifInterface.html" rel="nofollow">https://developer.android.com/reference/android/media/ExifInterface.html</a> also no documentation about getDateTime() and getGpsDateTime()</p>
  
  <p>I already searched about this issue but no luck. Did i missed something? Please don't answer about alternatives to get date time or gps date time, since i already know how to do that, i just curious about the concept here. </p>
