如何在Android中恢复前置摄像头的翻转图片？

Question

Can not figure out for couple of days now how to resolve my flipped picture from front camera on Android 4.

I want to rotate them on this way, but for some reason android don`t detect rule for front facing camera and OS version.

    public static float getDegree(int exifOrientation) {
    if (exifOrientation == ExifInterface.ORIENTATION_ROTATE_90)
        return 180;
    else if (exifOrientation == ExifInterface.ORIENTATION_ROTATE_180)
        return 270;
    else if (exifOrientation == ExifInterface.ORIENTATION_ROTATE_270)
        return 0;

    Camera.CameraInfo info = new Camera.CameraInfo();
    android.hardware.Camera.getCameraInfo(0, info);
    if (android.os.Build.VERSION.SDK_INT>13 && info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT)
    {
        return 270;
    }
    else {
        return 90;
    }

Any suggestions?

Create two arrays: one that contains the data for vertical lines and one for temporary data (they should have the same size). Then create a loop where you start from the length of the first array and go to 0. On every iteration, add the data from that vertical line array to the another one. Then just convert the temporary array to an image if you will.
