Browse source 
Set the following android result metadata:
- ANDROID_LENS_FOCAL_LENGTH
- ANDROID_LENS_APERTURE
- ANDROID_JPEG_GPS_TIMESTAMP
- ANDROID_JPEG_GPS_COORDINATES
- ANDROID_JPEG_GPS_PROCESSING_METHOD

And the following EXIF fields:
- GPSDatestamp
- GPSTimestamp
- GPSLocation
  - GPSLatitudeRef
  - GPSLatitude
  - GPSLongitudeRef
  - GPSLongitude
  - GPSAltitudeRef
  - GPSAltitude
- GPSProcessingMethod
- FocalLength
- ExposureTime
- FNumber
- ISO
- Flash
- WhiteBalance
- SubsecTime
- SubsecTimeOriginal
- SubsecTimeDigitized

Based on android request metadata.

This allows the following CTS tests to pass:
- android.hardware.camera2.cts.StillCaptureTest#testFocalLengths
- android.hardware.camera2.cts.StillCaptureTest#testJpegExif
