java - 尝试使用 ACTION_VIEW 打开文件时在 android 11 上找不到媒体

Question

我有一种方法用于从我的应用程序中打开文件，并且在 android 10 之前一切正常，但是当我尝试使用谷歌照片在 android 11 中打开文件时，它不会打开它并显示 Media not found toast。我正在尝试在任何外部应用程序中打开。

这是我正在使用的方法：

private void openFile(String url) throws IOException {
    // Create URI
    StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
    StrictMode.setVmPolicy(builder.build());
    Uri uri = Uri.parse(url);

    Intent intent = null;
    // Check what kind of file you are trying to open, by comparing the url with extensions.
    // When the if condition is matched, plugin sets the correct intent (mime) type,
    // so Android knew what application to use to open the file
    intent = new Intent(Intent.ACTION_VIEW);
    if (url.contains(".doc") || url.contains(".docx")) {
        // Word document
        intent.setDataAndType(uri, "application/msword");
    } else if(url.contains(".pdf")) {
        // PDF file
        intent.setDataAndType(uri, "application/pdf");
    } else if(url.contains(".ppt") || url.contains(".pptx")) {
        // Powerpoint file
        intent.setDataAndType(uri, "application/vnd.ms-powerpoint");
    } else if(url.contains(".xls") || url.contains(".xlsx")) {
        // Excel file
        intent.setDataAndType(uri, "application/vnd.ms-excel");
    } else if(url.contains(".rtf")) {
        // RTF file
        intent.setDataAndType(uri, "application/rtf");
    } else if(url.contains(".wav")) {
        // WAV audio file
        intent.setDataAndType(uri, "audio/x-wav");
    } else if(url.contains(".gif")) {
        // GIF file
        intent.setDataAndType(uri, "image/gif");
    } else if(url.contains(".jpg") || url.contains(".jpeg")) {
        // JPG file
        intent.setDataAndType(uri, "image/jpeg");
    } else if(url.contains(".png")) {
        // PNG file
        intent.setDataAndType(uri, "image/png");
    } else if(url.contains(".txt")) {
        // Text file
        intent.setDataAndType(uri, "text/plain");
    } else if(url.contains(".mpg") || url.contains(".mpeg") || url.contains(".mpe") || url.contains(".mp4") || url.contains(".avi")) {
        // Video files
        intent.setDataAndType(uri, "video/*");
    }

    //if you want you can also define the intent type for any other file

    //additionally use else clause below, to manage other unknown extensions
    //in this case, Android will show all applications installed on the device
    //so you can choose which application to use


    else {
        intent.setDataAndType(uri, "*/*");
    }

    this.cordova.getActivity().startActivity(intent);
}
