Nexus 5x reverse landscape sensor fix in a android camera preview app

by

The 5X camera is not “reverse”; it does report the correct camera orientation in its parameters, so no special workarounds are needed, just make sure you’re setting the display orientation correctly:

 public static void setCameraDisplayOrientation(Activity activity,
     int cameraId, android.hardware.Camera camera) {
 android.hardware.Camera.CameraInfo info =
         new android.hardware.Camera.CameraInfo();
 android.hardware.Camera.getCameraInfo(cameraId, info);
 int rotation = activity.getWindowManager().getDefaultDisplay()
         .getRotation();
 int degrees = 0;
 switch (rotation) {
     case Surface.ROTATION_0: degrees = 0; break;
     case Surface.ROTATION_90: degrees = 90; break;
     case Surface.ROTATION_180: degrees = 180; break;
     case Surface.ROTATION_270: degrees = 270; break;
 }

 int result;
 if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
     result = (info.orientation + degrees) % 360;
     result = (360 - result) % 360;  // compensate the mirror
 } else {  // back-facing
     result = (info.orientation - degrees + 360) % 360;
 }
 camera.setDisplayOrientation(result);
}
