android - android只分享意图到谷歌驱动器

Question

我已经设置了共享图像和标题的共享意图，但它只被定向到谷歌驱动器，我不明白为什么..这是代码：

Intent shareCaptionIntent = new Intent(Intent.ACTION_SEND);
                shareCaptionIntent.setType("image/*");

                //set photo
                Uri examplePhoto = Uri.fromFile(getExternalFilesDir(filepath[position]));
                shareCaptionIntent.setData(examplePhoto);
                shareCaptionIntent.putExtra(Intent.EXTRA_STREAM, examplePhoto);

                //set caption
                shareCaptionIntent.putExtra(Intent.EXTRA_TITLE, modelname);
                startActivity(Intent.createChooser(shareCaptionIntent,"share using:"));
