这是ExifInterface中的错误吗？

Question

我的问题是,在某些设备上,从库中选取后,一些图像在ImageView中旋转.我发现了很多使用ExifInterface来解决这个问题的信息,所以我尝试使用它.但是当我尝试使用图像路径创建ExifInterface实例时,我有一个奇怪的例外.

W/ExifInterface: Invalid image
java.io.IOException: Invalid marker: 89

我的道路没有错,因为我之前使用它并且它有效.这是我的代码.

        private void setLogo() {
        File mediaStorageDir = new File(Environment.getExternalStorageDirectory()
                + "/Android/data/"
                + getActivity().getPackageName()
                + "/Files");

        String mImageName="iGeoTrackUserAvatar.jpg";

        File mediaFile = new File(mediaStorageDir.getPath() + File.separator + mImageName);

//        if (mediaFile.exists()) {
//            Glide.with(getActivity())
//                    .load(mediaFile)
//                    .transform(new SystemUtils.CircleTransform(getActivity()))
//                    .diskCacheStrategy(DiskCacheStrategy.NONE)
//                    .skipMemoryCache(true)
//                    .into(mUserLogo);
//        }

        Bitmap bitmap = BitmapFactory.decodeFile(mediaFile.getPath());

        try {
            bitmap = modifyOrientation(bitmap, mediaFile.getAbsolutePath());
        } catch (IOException e) {
            e.printStackTrace();
        }

        mUserLogo.setImageBitmap(bitmap);
    }

我从stackoverflow.com上的许多答案中找到了这段代码

public static Bitmap modifyOrientation(Bitmap bitmap, String image_absolute_path) throws IOException {
    ExifInterface ei = new ExifInterface(image_absolute_path);
    int orientation = ei.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);

    switch (orientation) {
        case ExifInterface.ORIENTATION_ROTATE_90:
            return rotate(bitmap, 90);

        case ExifInterface.ORIENTATION_ROTATE_180:
            return rotate(bitmap, 180);

        case ExifInterface.ORIENTATION_ROTATE_270:
            return rotate(bitmap, 270);

        case ExifInterface.ORIENTATION_FLIP_HORIZONTAL:
            return flip(bitmap, true, false);

        case ExifInterface.ORIENTATION_FLIP_VERTICAL:
            return flip(bitmap, false, true);

        default:
            return bitmap;
    }
}

public static Bitmap rotate(Bitmap bitmap, float degrees) {
    Matrix matrix = new Matrix();
    matrix.postRotate(degrees);
    return Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
}

public static Bitmap flip(Bitmap bitmap, boolean horizontal, boolean vertical) {
    Matrix matrix = new Matrix();
    matrix.preScale(horizontal ? -1 : 1, vertical ? -1 : 1);
    return Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
}

我没有发现任何关于这个问题,但我发现Jake Wharton 提到它可能是Android中的错误.你能帮助我吗？因为我无法理解如何解决这个问题.

CommonsWare的建议非常好.当我使用Gradle编译时,com.android.support:exifinterface:25.1.0这个类已经开始工作而不是标准实现.
