Android10.0图片保存遇到一些问题

在Android10.0中进行图片保存时,运行这一句代码:

MediaStore.Images.Media.insertImage(MainActivity.this.getContentResolver(), storepath, imgpath, null)

会出现如下错误:

java.lang.IllegalArgumentException: MIME type application/octet-stream cannot be inserted into content://media/external/images/media; expected MIME type under image/

程序闪退,但是图片可以保存在文档中。请问这个问题怎么解决?
保存图片的整个函数如下:

    public void saveimg(){
        if (bitmap2==null){
            Toast toast=Toast.makeText(MainActivity.this,"图像尚未处理,无法保存",Toast.LENGTH_SHORT);
            toast.show();
        }
        else {
            final MyAlertInputDialog myAlertInputDialog = new MyAlertInputDialog(this).builder()
                    .setTitle("请输入")
                    .setEditText("");
            myAlertInputDialog.setPositiveButton("确认", new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    myAlertInputDialog.dismiss();
                    String storepath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Pictures";
                    String imgpath = myAlertInputDialog.getResult().toString() + ".jpg";
                    FileOutputStream fos = null;
                    try {
                        File file = new File(storepath, imgpath);
                        fos = new FileOutputStream(file);

                        bitmap2.compress(Bitmap.CompressFormat.JPEG, 100, fos);
                        fos.flush();
                        fos.close();
                    } catch (FileNotFoundException e) {
                        e.printStackTrace();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                    try {
                        MediaStore.Images.Media.insertImage(MainActivity.this.getContentResolver(), storepath, imgpath, null);
                    } catch (FileNotFoundException e) {
                        e.printStackTrace();
                    }
                    sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" + storepath + "/"+imgpath)));

                }
            }).setNegativeButton("取消", new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                    myAlertInputDialog.dismiss();
                }
            });
            myAlertInputDialog.show();
        }
    }

在Android10.0以下的机型都可以正常运行。

试试换其他方法保存图片

ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.DATA, imgFile.getAbsolutePath());
values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg(图片类型)");
Uri uri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
