How to set Android camera orientation properly

Question

I want to set the camera orientation according to the device orientation in Android but nothing seems to be working  I tried to rotate the Surface as well as the camera parameters but the camera preview in portrait mode always comes upside down  I would need to rotate it by 90 degree clockwise for it to be correct  Here is the code I am using right now which works in landscape mode only       SurfaceHolder Callback surfaceCallback   new SurfaceHolder Callback           Override     public void surfaceDestroyed SurfaceHolder holder            camera stopPreview            camera release            camera   null              Override     public void surfaceCreated SurfaceHolder holder                      initCamera                          private Size getOptimalPreviewSize List lt Size gt  sizes  int w  int h            final double ASPECT TOLERANCE   0 2          double targetRatio    double  w   h          if  sizes    null              return null           Size optimalSize   null          double minDiff   Double MAX VALUE           int targetHeight   h              Try to find an size match aspect ratio and size         for  Size size   sizes                Log d TAG   Checking size     size width    w     size height                        h                double ratio    double  size width   size height              if  Math abs ratio - targetRatio   gt  ASPECT TOLERANCE                  continue              if  Math abs size height - targetHeight   lt  minDiff                    optimalSize   size                  minDiff   Math abs size height - targetHeight                                       Cannot find the one match the aspect ratio  ignore the            requirement         if  optimalSize    null                minDiff   Double MAX VALUE              for  Size size   sizes                    if  Math abs size height - targetHeight   lt  minDiff                        optimalSize   size                      minDiff   Math abs size height - targetHeight                                                     return optimalSize              Override     public void surfaceChanged SurfaceHolder holder  int format  int width  int height            Camera Parameters parameters   camera getParameters             List lt Size gt  sizes   parameters getSupportedPreviewSizes            Size optimalSize   getOptimalPreviewSize sizes  width  height                    Log d TAG   Surface size is     width    w     height    h            Log d TAG   Optimal size is     optimalSize width    w     optimalSize height    h                       parameters setPreviewSize optimalSize width  optimalSize height                         parameters setPreviewSize width  height                       camera setParameters parameters           camera startPreview

From other member and my problem   Camera Rotation issue depend on different Devices and certain Version   Version 1 6  to fix the Rotation Issue  and it is good for most of devices  if  getResources   getConfiguration   orientation    Configuration ORIENTATION PORTRAIT                           p set  orientation    portrait                p set  rotation  90                     if  getResources   getConfiguration   orientation    Configuration ORIENTATION LANDSCAPE                                                       p set  orientation    landscape                          p set  rotation   90               Version 2 1   depend on kind of devices  for example  Cannt fix the issue with XPeria X10  but it is good for X8  and Mini  Camera Parameters parameters   camera getParameters    parameters set  orientation    portrait    camera setParameters parameters     Version 2 2  not for all devices  camera setDisplayOrientation 90     http   code google com p android issues detail id 1193 c42

I finally fixed this using the Google s camera app  It gets the phone s orientation by using a sensor and then sets the EXIF tag appropriately  The JPEG which comes out of the camera is not oriented automatically   Also  the camera preview works properly only in the landscape mode  If you need your activity layout to be oriented in portrait  you will have to do it manually using the value from the orientation sensor

This solution will work for all versions of Android  You can use reflection in Java to make it work for all Android devices   Basically you should create a reflection wrapper to call the Android 2 2 setDisplayOrientation  instead of calling the specific method   The method       protected void setDisplayOrientation Camera camera  int angle       Method downPolymorphic      try               downPolymorphic   camera getClass   getMethod  setDisplayOrientation   new Class     int class             if  downPolymorphic    null              downPolymorphic invoke camera  new Object     angle               catch  Exception e1                  And instead of using camera setDisplayOrientation x  use setDisplayOrientation camera  x         if  Integer parseInt Build VERSION SDK   gt   8          setDisplayOrientation mCamera  90       else               if  getResources   getConfiguration   orientation    Configuration ORIENTATION PORTRAIT                        p set  orientation    portrait                p set  rotation   90                     if  getResources   getConfiguration   orientation    Configuration ORIENTATION LANDSCAPE                        p set  orientation    landscape                p set  rotation   90
