照片和保存的图像无法在 openAblum 里找到

[StevenLOL]

保存一个图片 到图片库的一个已知目录，在 openAblum 里面无法 找到，哪怕重启 app。 直到在外部用文件管理器打开那个目录并刷新 才可以 在app 里看到。

尝试过一下 方案，没有成功

sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(imageAdded)));

感谢提BUG 会尽快修复

我临时用下面的方法 （RequiresApi(api = Build.VERSION_CODES.KITKAT)）

private void openAblum() {

        Intent pickIntent = new Intent();
        pickIntent.setType("image/*");
        pickIntent.setAction(Intent.ACTION_GET_CONTENT);
        if (photoURI!=null) {

            this.context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, photoURI));

        }
        String pickTitle = "Select or take a new Picture"; // Or get from strings.xml
        Intent chooserIntent = Intent.createChooser(pickIntent, pickTitle);
        startActivityForResult(chooserIntent, SELECT_GALLERY_IMAGE_CODE);

    }

   @RequiresApi(api = Build.VERSION_CODES.KITKAT)
    private void handleSelectFromAblum(Intent data) {
        Uri fileuri=data.getData();
        path = HelperClass.getPath(this.context,fileuri);
        showMesage("path---->"+path);
        startLoadTask();
    }
