title: Supported FPS in Camera2 API
body: <p>I am trying to get supported Frames per second values from Camera2 API using below code.</p>
  
  <pre><code>CameraManager manager = (CameraManager)activity.getSystemService(Context.CAMERA_SERVICE);
  ...
  String cameraId = manager.getCameraIdList()[0];
  CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraId);
  Range&lt;Integer&gt;[] fpsRanges = characteristics.get(CameraCharacteristics.CONTROL_AE_AVAILABLE_TARGET_FPS_RANGES);
  </code></pre>
  
  <p>Developer site says <code>CONTROL_AE_AVAILABLE_TARGET_FPS_RANGES</code> is used to get list of frame rate ranges for <code>CaptureRequest#CONTROL_AE_TARGET_FPS_RANGE</code> supported by the camera device.</p>
  
  <p>These are the values of fpsRange(upper and lower) array for Pixel2 mobile.</p>
  
  <pre><code>[15, 15], [24, 24], [7, 30], [30, 30], [7, 60], [60, 60]
  </code></pre>
  
  <p>Does this mean the above mentioned device supports Frame rates from 7 to 60 i.e. 7, 15, 24, 30 and 60? I am bit confused about these values.</p>
