解決辦法：

int degree = ImageUtil.readPictureDegree(imageUri.getPath());
Bitmap bmpOk = ImageUtil.rotateToDegrees(bmp, degree);

/**
 * 圖片旋轉 * @param tmpBitmap
* @param degrees
* @return
*/
public static Bitmap rotateToDegrees(Bitmap tmpBitmap, float degrees) {
    Matrix matrix = new Matrix();
matrix.reset();
 
matrix.setRotate(degrees);
    return tmpBitmap =
            Bitmap.createBitmap(tmpBitmap, 0, 0, tmpBitmap.getWidth(), tmpBitmap.getHeight(), matrix,
                    true);
}

/**
 * 讀取照片exif資訊中的旋轉角度 * @param path 照片路徑
* @return角度  */
public static int readPictureDegree(String path) {
    int degree = 0
 
;
    try {
        ExifInterface exifInterface = new ExifInterface(path);
        int orientation =
                exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_NORMAL);
        switch (orientation) {
            case ExifInterface.ORIENTATION_ROTATE_90:
                degree = 90
 
;
                break;
            case ExifInterface.ORIENTATION_ROTATE_180:
                degree = 180;
                break;
            case ExifInterface.ORIENTATION_ROTATE_270:
                degree = 270;
                break;
}
    } catch (IOException e) {
        e.printStackTrace();
}
    return degree;
}

bmpOK就是我們需要的沒有旋轉過的照片了。
