android - 储存在牛轧糖中

Question

我编写了以下代码来存储拍摄的图像照片。但由于某种原因，它适用于美国的所有 Android 操作系统，但不适用于保加利亚的牛轧糖。我无法访问保加利亚，但我的应用用户说他们无法存储图像。

Post.java

@Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        switch (requestCode) {
            case PermissionUtil.MY_PERMISSIONS_REQUEST_WRITE_EXTERNAL_STORAGE:
                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    switch (ImageUtil.userSelectionID) {
                        case R.id.selectPhotoProduct:
                            ImageUtil.showFileChooser(this);
                            break;
                        case R.id.takePhotoProduct:
