Android custom camera image inverted Solution

Some mobile phone images are upside down. How can this problem be solved? See the following 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 (). getdefadisplay display (). 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 );}

@Overridepublic void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) {// TODO Auto-generated method stub
                setCameraDisplayOrientation(this,0,camera)
}
